deptid is the foreign "ey referencing the primary "ey deptid of table dept.

In case a department is closed+ the department row needs to be deleted from @dept@ table. Since foreign

"ey constraint e4ists+ the department row cannot be deleted if there are any employees in that

department.

To o!ercome the abo!e+ an -FT)* T*IGG)* was created on the @dept@ table with code to delete the

indi!idual employee rows based on the deptid.

hich of the following is the final outcome of issuing a %)')T) statement for a deptid in the @dept@ table/

- The employee rows in table empgets deleted and the department row in dept table is then deleted

? The employee rows in emp table alone get deleted

C The department row in dept table alone gets deleted

&he delete on dept table fails due to foreign #ey constraint and no further deletions ta#e place
