SQL Standard (a ldquoshortrdquo introduction)

Well-known de jure database language standard

Mature standard but still evolving

ISO standard (ISOIEC 9075) developed collaboratively by a number of national bodies

(USA UK Germany Canada Japan Netherlands Sweden etc)

National body standards identical to the ISO standard

Many implementations - with varying degrees of conformance

Large number of applications



SQL Basics

Data structured as tables

Declarative query expressions to retrieve data from tables

Update operations (INSERT UPDATE DELETE)

Declarative constraints and triggers

Security model based on the concept of privileges and grantingrevoking those privileges

Control of concurrent access and system failures through transaction mechanism

Schema evolution

Recent enhancements SQLXML and temporal queries

many more

SQL Standard ndash Parts Overview

Part 1 SQLFramework

ndash Structure of the standard and relationship between various parts

ndash Common definitions and concepts

ndash Conformance requirements statement

Part 2 SQLFoundation

ndash Specifies the core language - all of SQL1999Foundation plus a few extensions

bull DDL for creating altering and dropping various persistent objects including tables

views user-defined types and SQL-invoked routines

bull Predefined data types + type constructors

bull DML for retrieving and updating persistent data

bull Scalar and table expressions

bull Predicates

bull Host language bindings dynamic SQL and direct SQL



SQL Standard ndash Parts Overview (cont)

Part 3 SQLCLI

ndash A Call-Level Interface for invoking SQL from applications

ndash Consists of over 60 routine specifications

bull Control connections to SQL-servers

bull Allocate and deallocate resources

bull Execute SQL statements

bull Control transaction termination

bull Obtain information about the implementation

ndash Provided for vendors of truly portable shrink wrapped software

bull CLI does not require pre-compilation of the application program

bull Application program can be delivered in shrink wrapped object-code form




Part 4 SQLPSM (Persistent Stored Modules)

ndash Procedural language constructs (similar to those found in block-structured languages)

bull Improve performance in centralized and clientserver environments

Multiple SQL statements in a single EXEC SQL

Multi-statement procedures functions and methods

ndash Gives great power to DBMS

bull Several control statements (procedural language extension)

beginend block assignment call case if loop for signalresignal variables

exception handling

ndash SQL-only implementation of complex functions

bull Without worrying about security (firewall)

bull Without worrying about performance (local call)




Part 9 SQLMED (Management of External Data)

ndash Two distinct concepts

bull Datalinks

External data coordinated by SQL-server

External data accessed through native interface

External data kept consistent with SQL-data

bull Foreign Data (or Wrapper interface)

External data not controlled by SQL-server

External data accessed through SQL-server

Data access from multiple sources transparently

Part 10 SQLOLB (Object Language Bindings)

ndash Embedding of SQL statements in Java programs

ndash Many differences from the traditional host language bindings

bull specification in terms of JDBC but static compilation

bull provides typed cursors and better exception handling

bull platform independence (binary portability)

ndash precursor SQLJ Part 0




Part 11 SQLSchemata

ndash Specification of over 65 views that describe the metadata in the SQL-environment

bull TABLES

bull COLUMNS

bull USER_DEFINED_TYPES etc

ndash Exist in schema INFORMATION_SCHEMA

ndash Can be queried by users - see only those objects that are either owned or have some

privilege on

ndash Cannot be updated by users

ndash Underlying base tables created in a hypothetical schema DEFINITION_SCHEMA -

automatically updated every time a DDL statement is executed

Part 13 SQLJRT (Javatrade Routines and Types)

ndash SQL extensions that allow creation of

bull SQL-invoked routines corresponding to Java static methods

bull SQL user-defined structured types corresponding to Java classes

ndash precursor SQLJ Parts 1 amp 2




Part 14 SQLXML

ndash Major goals

bull Publish SQL query results as XML documents

bull Ability to store and retrieve XML documents

bull Query XML data

ndash Rules for mapping SQL types SQL identifiers and SQL data values to and from

corresponding XML concepts

ndash A new built-in type XML

bull Based on the XQuery data model

bull Can be an XML document or more complex (ie a sequence in the XQuery data

model)

ndash A number of built-in operators that produce values of type XML

ndash A number of built-in expressions to querymanipulate XML values

bull XMLTable

bull XMLQuery

bull XMLExists

bull XMLCast



Conformance

SQL-92 used incremental levels of conformance (Entry Intermediate Full)

SQL1999 SQL2003 SQL2008 and SQL2011 consist of a large number of small

features each identified and precisely specified as to its content

Each feature is specified either to be a constituent of Core SQL or not a constituent of

Core SQL

ndash SQL2003 SQL2008 and SQL2011 did not add any features to Core

Implementations can claim

ndash minimum conformance (Core SQL)

bull conformance to certain features of parts 2 (Foundation) and 11 (Schemata)

ndash conformance to a part (0 or more)

bull mandatory features of part + addtl conformance requirements of part

ndash conformance to optional feature (0 or more)

bull may imply conformance to other features



Overview of SQL2011 Core Features

All of SQL-92 Entry level

Some Intermediate SQL-92 features

Some Full SQL-92 features

The following features of SQL1999

ndash Distinct data types including USER_DEFINED_TYPES view

ndash WITH HOLD cursors

ndash SQL-invoked routines (but not the ability to explicitly specify a PATH or overloading)

bull SQL-invoked routines written in SQL or an external language (one can conform by

supporting only one)

bull RETURN statement (for functions written in SQL)

bull CALL statement (with the extension to dynamic SQL to support CALL)

bull ROUTINES and PARAMETERS view

ndash Value expression in order by clause

SQL2003 SQL2008 and SQL2011 did not add any features to Core

Agenda







Features added in DB2 1012

Weakly typed distinct types

Pipelined table functions


copy 2013 IBM Corporation Need webcast troubleshooting help Click attachments


Purpose

ndash Compatibility to Oracle SUBTYPE

ndash Use a unique alias for the data type of a group of variables parameters and columns to provide a single point of control over their type

ndash Provide check constraints for distinct types which allows for data types with more restrictive domains than base types (eg COLOR ZIPCODE)

ndash Relax current distinct type strong typing rules

Scope ndash Parameters variables and table columns (without constraints only)

29

29


Weakly typed distinct types example

CREATE TYPE color AS CHAR(1) WITH WEAK TYPE RULES

NOT NULL CHECK (VALUE IN (lsquoRrsquolsquoGrsquolsquoBrsquo))

CREATE VARIABLE my_color color DEFAULT lsquoRrsquo

SET my_color = lsquoWrsquo

SQL20552N The cast or assignment failed because the value does not conform to the data type constraint of the user-defined type User-defined type COLOR Value W

CREATE TYPE hellip WITH WEAK TYPE RULES

ndash Function resolution treats type as base type

ndash Optional check constraint and NOT NULL constraint

Ref ldquoDistinctly weak type rules with a constrained twistrdquo at wwwibmcomdeveloperworkscommunityblogsSQLTips4DB2LUWentryweak_type

30

30



Purpose ndash Compatibility to pipelined functions in Oracle

ndash Incrementally produce a result set for consumption on demand

Problem ndash Java C and NET table functions provide support but require host

language skill

ndash Inline SQL table functions must compose the result set in a single RETURN statement

Solution ndash PIPE statement returns a row to caller but continues at next statement

if caller wants another row

31

31


Pipelined table functions Example

CREATE FUNCTION dates(IN dt DATE) RETURNS TABLE(dt DATE) BEGIN LOOP PIPE (dt) SET dt = dt + 1 DAY END LOOP RETURN END

SELECT FROM TABLE(dates(2013-01-01)) FETCH FIRST 2 ROWS ONLY DT 2013-01-01 2013-01-02

Indexes based on expressions

Indexes that exclude null keys

Indexes with random order

Not enforced unique and primary key constraints

Ad-hoc federated table access

Tables with extended row size




Purpose ndash Add support for indexes with expression-based keys such that queries

with these predicates on expressions can exploit the indexes

ndash Avoid the drawbacks of work-around (index on generated column)

ndash Compatibility with DB2 family

ndash Commonly used in Oracle to perform case insensitive searches and to index over complex expressions

Solution

ndash Allow expressions for parts of index key

ndash Index statistics are collected through an associated statistical view that is generated automatically

34

34


Indexes based on expressions Examples

-- an index on employee name and id columns

CREATE INDEX emp_name ON employee(name id)

-- an index with an expression-based key using upper case

-- of employee name (still include the id column)

CREATE INDEX emp_upper ON employee(upper(name) id)


-- of employee name total employee compensation and id column

CREATE INDEX emp_comp on employee(upper(name) salary + bonus id)

35

35


Index based on expressions Catalog representation


SYSCATINDEXES

SYSCATINDEXCOLUSE

INDNAME COLCOUNT COLNAMES INDEXTYPE

EMP_COMP 3 +K00+K01+ID REG

INDNAME COLSEQ COLNAME TEXT

EMP_COMP 1 K00 UPPER(NAME)

EMP_COMP 2 K01 SALARY + BONUS

EMP_COMP 3 ID -

36


Index based on expressions Statistical view

CREATE INDEX user1emp_comp on user1employee (upper(name) salary + bonus id)

Generated statistical view

CREATE VIEW ldquoUSER1EMP_COMP_V(K00 K01 ldquoID) AS

SELECT UPPER(NAME)

SALARY + BONUS

ldquoID

FROM ldquoUSER1EMPLOYEEldquo

RUNSTATS against table and indexes as usual also collects statistics for the statistical view

Caution The generated statistical view cannot be used in other statements by any user select k00 k01 id from user1emp_comp_v

SQL0551N The statement failed because the authorization ID does not have the

required authorization or privilege to perform the operation Authorization

ID ldquoSWAGRMAN Operation SELECT Object ldquoUSER1EMP_COMP_V

SQLSTATE=42501



Indexes that EXCLUDE NULL KEYS

Purpose ndash Allow for the creation of unique constraints that are not enforced for

duplicate null keys

ndash Reduce the size of indexes over a large number of null keys

ndash Compatibility with Oracle where indexes do not include null keys

Solution ndash INCLUDE NULL KEYS and EXCLUDE NULL KEYS clauses are added to the

CREATE INDEX statement

ndash INCLUDE NULL KEYS is the default

38

38


A NULL key is a key where all the key parts are NULL

Consider possible indexes

ndash create unique index ENK on t1 (c1 c2) exclude null keys

ndash create unique index INK on t1 (c1 c2) include null keys


Unique Constraint Insert

C1 C2

NULL NULL

C1 C2 ENK Index INK Index

NULL 1 Success Success

2 NULL Success Success

NULL NULL Success Success

NULL NULL Success Fail

39

Excluded from ENK index

(included in table)

Need webcast troubleshooting help Click attachments


Indexes that EXCLUDE NULL KEYS Usage

Indexes created with the ENK clause do not index rows where all key parts are null

ENK indexes can be used for query optimization when one or more index key parts are used in null-rejecting predicates ndash SELECT FROM T1 WHERE C1 = 5

ndash SELECT FROM T1 T2 WHERE T1C1 = T2C1

40

40


Indexes that EXCLUDE NULL KEYS Examples

-- an EXCLUDE NULL KEYS index on customer email

CREATE INDEX cust_email ON customer(email) EXCLUDE NULL KEYS

-- an INCLUDE NULL KEYS index on customer id name

CREATE INDEX cust_key ON customer(id name) INCLUDE NULL KEYS

SYSCATINDEXES

INDNAME NULLKEYS

CUST_EMAIL N

CUST_KEY Y

Sample motivating scenario

ndash An online store defines an ORDER_NUM column

ndash ORDER_NUM is indexed for fast lookups

ndash Each concurrent transaction gets a newly incremented ORDER_NUM value

ndash Results in frequent attempts by each member to update last index leaf page to

add the latest ORDER_NUM

Random key indexes

CREATE INDEX i1 ON t1 (INT ORDER_NUM RANDOM)

ndash Each ORDER_NUM is randomized before insertion into the index

ndash Spreads access requests evenly across index leaf pages

ndash Lookups apply reverse algorithm

ndash Not usable for scans



NOT ENFORCED unique and primary key constraints

Constraint attribute NOT ENFORCED extended to include unique and primary key constraints

ndash Already supported for check and referential constraints

Use when data is known unique but index and enforcement not needed

No longer and underlying index to enforce the uniqueness

Optimizer still takes advantage of the information but without an index

Target usage is for column-organized tables where indexes are not used

If an enforced referential constraint exists the parent unique or primary key constraint must also be enforced

There is no ALTER TABLE support to toggle between NOT ENFORCED and ENFORCED

ndash Drop the constraint and add it again with the different enforcement




Problem

ndash Historically DB2 required creation of a NICKNAME to access a

remote table

ndash Syntax is incompatible with Oracle

Solution

ndash Support an ad-hoc reference to a remote table using the server in

the identifier DB2 105 adds this support for static (SQL PL and

PLSQL) statements

ndash DB2 select from serverschematable

ndash Oracle select from schematableserver

44

44



Purpose ndash Support applications that require large row size

ndash Avoid length table redefinitions to change pagesize on migration

ndash Allow tables with defined row size gt 32K max page size

Target users ndash Database schema design that defines string columns as bigmaximum

length when the actual content is typically much smaller

ndash Tables with many columns that are usually NULL but can be large

ndash Migrating tables with row sizes greater than 32KB to DB2

Solution ndash Large strings treated like LOB if actual row size exceeds page size limit

ndash Designed assuming that a small percentage of rows will spill over

45

45


Tables with extended row size Externals

EXTENDED_ROW_SZ database configuration parameter

ndash Defaults to ENABLED for databases created in DB2 105 or later

ndash Defaults to OFF for databases created prior to DB2 105

In CREATE TABLE table space selection defaults to the table space

with the smallest page size that can accommodate the table without

extended row size

If this search fails a second search is conducted that defaults to the

largest page size that can accommodate the table with extended row

size

Of course you should always specify the table space you want

46

46


Tables with extended row size Internals

INSERT or UPDATE which cause the row to exceed the page size of

the table space causes a subset of varying length string columns to

be stored as LOB data

UPDATE which shrinks the size of the row to be within the page size

will return to using the varcharvargraphic storage of string data

47

47


Tables with extended row size Limits

The extended row size length limit is 1048319 bytes

(just under 1MB)

Individual VARCHAR and VARGRAPHIC column length limits are not

changed (from 32672 and 16338 respectively)

The maximum number of columns allowed for a particular page size

is not changed (500-1012 currently)

48

48


Tables with extended row size Catalog representation

SYSCATTABLESEXTENDED_ROW_SIZE

ndash Y ndash Row size exceeds the maximum record length for the page size

ndash N - Row size does not exceed the maximum for the page size

SYSCATTABLESPCTEXTENDEDROWS

ndash Extended rows as a percentage of total rows in the table

ndash -1 if statistics are not collected

Performance penalty when need to go bdquooff page‟ for a portion of row

ndash For intended scenarios instances of long rows are rare

ndash If you expect long rows to be common use a larger page size if possible

49

49


SQL Compatibility A Steady Increase

Steady increase in compatibility over time

ndash More and more complex applications

DB2 105 estimated to provide gt98 statement compatibility

Data is based on DCW (Database Conversion Workbench) DB2 reports



Agenda







Reflections of a database language architect

SQL has grown tremendously over the past 20 years (DB2 and Standard)

Tendency to look at the changes incrementally from release to release ndash Eg Can I use this new feature that was delivered

Are we taking advantage of the incredible power of SQL that the

combination of these incremental changes has provided

Are there ldquoforgotten old toolsrdquo in the tool box that you could be using

perhaps together with the ldquoshiny new toolsrdquo



Early SQL (circa 1990)

Life as SQL user was simpler but way more limited

The DB2 SQL Reference manual was about 200 pages

Consider that

ndashFROM clause allowed table or view names with implicit inner join

ndashLogic was mostly in a WHERE clause with a set of predicates (basic quantified BETWEEN EXISTS IS NULL LIKE and IN)

bull Also in the HAVING clause for grouping sets

ndashThere were only 5 aggregate functions

ndashThere were only 20 built-in scalar functions

ndashThere were no user-defined procedures functions types triggers etc



Modern SQL (circa 2013)

Consider current SQL support particularly for query and data manipulation

ndashFROM clause

ndashLogic and control capabilities

ndashBuilt-in functions

ndashTriggers

ndashUser-defined procedures functions and modules



FROM clause

Explicit JOIN (INNER LEFT RIGHT and FULL OUTER) with ON clause

Nested table expression or derived table allows a fullselect ndash Allows a query to be performed on the result of another query (maybe

including aggregations or order by and fetch first clauses) ndash Much like specifying query from a view instead of the view name ndash Includes possibility of a ldquoconstant tablerdquo using the VALUES form of fullselect

References to federated tables as nicknames or 3-part names

References to data change table representing ndash new rows from insert operation ndash old rows from delete operation ndash old or new rows from update operation

References to built-in or user-defined table functions including ndash UNNEST to convert an array to a result table ndash XMLTABLE to query an XML document and return a result table based on the

sequence

Period specification for temporal table queries (AS OF FROM TO and BETWEEN)



Logic and control capabilities

Basic quantified and IN predicates with comparison of row value

expression

Some additional specialized predicates added ndash ARRAY_EXISTS XMLEXISTS trigger event predicates cursor predicates

CASE expression provides powerful inline logic

SQL PL extended logic support to also control flow

ndashEg CASE FOR IF ITERATE REPEAT WHILE etc

Compound SQL statement can use SQL PL and be a stand alone

statement or get used as the body of a procedure function or trigger

MERGE statement provides statement level logic to determine update

delete or insert processing of data



Built-in functions

Over 20 aggregate functions

Over 200 scalar functions ndash string numeric datetime cast array XML etc

8 specific window (or OLAP) functions plus use of most aggregate

functions over a window ndash LAG LEAD

ndash RANK DENSE_RANK ROW_NUMBER

ndash FIRST_VALUE LAST_VALUE RATIO_TO_REPORT



Triggers

Associate automatic operations with data change operations on tables

within the database

BEFORE triggers can change the values to be inserted or updated and

can also be used for more complex checking of new values

AFTER triggers can be used for other operations related to the data

change

Use SQL PL and compound SQL for triggered action definition

Ability to invoke user-defined procedures and functions within trigger

Combine or separate triggers by event ndash Insert update delete or any combination of these

ndash For combination trigger use trigger event predicates (inserting updating

deleting)



User-defined procedures functions and modules

Allows user to define application logic or commonly used operations in the

database

Procedures and functions can be written in SQL or an external language

like C or Java

Definitions of procedures and functions can be overloaded (by various

criteria)

More recent additions made definition and use even more flexible ndash Defined defaults for parameters

ndash Associate parameter name with arguments when invoking procedure or

function

Modules can be defined to group a set of procedures functions types

variables and conditions ndash Module objects can be published or defined for use only within the module

ndash Module object usage outside of the module generally requires module name as

additional qualifier

There are also user-defined types to be consideredhellip 59 Need webcast troubleshooting help Click attachments


Example Destructive read

Retrieve and delete the next lowest order number

SQL features used 1 Data change operation in a FROM clause

2 Fullselect as target of DELETE

3 ORDER BY and FETCH FIRST in subselectfullselect

4 Deletable even with ORDER BY clause

60

SELECT ordernum INTO ordernum

FROM OLD TABLE(DELETE -- 1

FROM (SELECT FROM orders -- 2

ORDER BY ordernum -- 3

FETCH FIRST ROW ONLY)) -- 4

Could also use a separate SELECT INTO (which would still use features 3

and 4) followed by searched DELETE



Example ndash Top 2 per department

Retrieve the top 2 wage earners by workdept

SQL features used 1 Nested table expression in a FROM clause

2 RANK window function

61

SELECT EMPNO WORKDEPT WAGES RANK_WAGES

FROM (SELECT EMPNO WORKDEPT SALARY+BONUS AS WAGES -- 1

RANK() OVER (PARTITION BY WORKDEPT -- 2

ORDER BY SALARY+BONUS DESC)

AS RANK_WAGES

FROM EMPLOYEE) AS RANK_BY_DEPT

WHERE RANK_WAGES lt 3 ORDER BY WORKDEPT RANK_WAGES

Nested table expression was used to compute the rank before the rank could

be used in the WHERE clause Common table expression could also be used




When faced with an SQL challenge

ndashConsider the depth of available SQL capabilities

ndashExplore the extensible nature of SQL for creative solutions

ndash If one approach encounters a restriction or missing feature look for

another way

ndashShare your creative solutions with other SQL users bull For example go ahead and send your solution to me and I can post it on

sqltips4db2com (giving you credit for it of course)
