ISSUE: 6365
|
|
TITLE: The Metadata script extracted using ISQL of a database restored from a Firebird
|
|
2.5.9 Backup is invalid/incorrect when table has COMPUTED BY field
|
|
DESCRIPTION:
|
|
Test uses backup of preliminary created database in FB 2.5.9, DDL is the same as in the ticket.
|
|
This .fbk is restored and we launch ISQL -X in order to get metadata. Then we check that two
|
|
in this script with "COMPUTED BY" phrase contain non zero number as width of this field:
|
|
1) line that belongs to CREATE TABLE statement:
|
|
FULL_NAME VARCHAR(100) ... COMPUTED BY ...
|
|
2) line with ALTER COLUMN statement:
|
|
ALTER FULL_NAME TYPE VARCHAR(100) ... COMPUTED BY ...
