# title: IIF function prevents the condition from being pushed into the union for better optimization
|
|
# decription:
|
|
# 1. Obtain engine_version from built-in context variable.
|
|
# 2. Make config for trace in proper format according to FB engine version,
|
|
# with adding invalid element 'foo' instead on boolean ('true' or 'false')
|
|
# 3. Launch trace session in separate child process using 'FBSVCMGR action_trace_start'
|
|
# 4. Run ISQL with calling test SP.
|
|
# 5. Stop trace session. Output its log with filtering only messages related to ticket notes.
