|

|

|
|
# On 5.0.0.88 and 4.0.1.2523 expression marked as [ 2 ] raises:
|
||
|
|
# "SQLSTATE = 22025/Invalid ESCAPE sequence",
|
||
|
|
# After fix its error became the same as for [ 1 ].
|
||
|
|
#
|
||
|
|
# NB: backslash character must be duplicated when SQL script is launched from Python,
|
||
|
|
# in contrary to common usage (pass script to ISQL utility from OS command prompt).
|
||
|
|
#
|
||
|
|
# Checked on: 5.0.0.113, 4.0.1.2539.
