ID: gtcs.ref-integ-drop-fk-index
|
|
TITLE: Index that is used for FK should not be avail for DROP
|
|
DESCRIPTION:
|
|
Original test see in:
|
|
https://github.com/FirebirdSQL/fbtcs/blob/master/GTCS/tests/REF_INT.4.ISQL.script
|
|
|
|
This test uses pre-created script ( <QA_ROOT>/files/gtcs-ref-integ-init.sql ) which creates two
|
|
tables with PK/FK referencing constraint(parent = department, child = employee).
|
|
FK-constraint uses index with name = 'ref_key', and here we try to:
|
|
* DROP this index;
|
|
* insert record in the child table which has no apropriate PK in the parent table.
|
|
(see 'sql_addi' variable which stores SQL statements for that).
|
|
Both actions should fail.
|
