ISSUE: 1577
|
|
TITLE: Prepare fails when having a parameter in a DSQL statement before a sub query
|
|
DESCRIPTION:
|
|
NOTES:
|
|
[19.1.2022]
|
|
Using WITH for prepare() call is important to dispose returned prepared statement before
|
|
connection is closed. Otherwise pytest will report unhandled exceptions in __del__ calls
|
|
as prepared statement objects are destructed at wrong time.
