Digging in to Key Features



Hidden Column

•Useful for protecting sensitive data from dynamic queries

•Hide a column by default

•Column is still there and can be manipulated directly


CREATE TABLE ZENDDATA/EMPMAST (

NAME CHAR (20 ) NOT NULL WITH DEFAULT,

CITY CHAR (20 ) NOT NULL WITH DEFAULT,

STATE CHAR (2 ) NOT NULL WITH DEFAULT,

SSN INT NOT NULL WITH DEFAULT IMPLICITLY HIDDEN)


Insert data…

•Must explicitly reference field on insert statement

(lost sleep here, but makes sense)

•Then values clause…


INSERT INTO

ZENDDATA.EMPMAST (NAME, CITY, STATE, SSN)

VALUES('Sheldon Cooper', 'San Jose', 'CA‘,567891234);


Let’s see…

•So using “select *” returns only the visible fields…



Hidden field

•Reference hidden field explicitly to reveal data



In PHP, why is this good

•Write dynamic routines to display data

•Database can manage what is seen by default

•But as a developer, you can still manipulate and control!



But what if I want to see this?

• Include the column in the select

•Now you can see it…
