# 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
|
|
# decription:
|
|
# 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 ...
|
|
#
|
|
# Confirmed bug on: 4.0.0.1723; 3.0.5.33225: found "VARCHAR(0)" in above mentioned lines.
|
|
# Checked on: 4.0.0.1737; 3.0.6.33236 - works fine.
