ISSUE: 5348
|
|
TITLE: ISQL plan output is unexpectedly truncated after a query is simplified to become shorter
|
|
DESCRIPTION:
|
|
Start of discussion: letter to dimitr, 30-dec-2015 13:57; its subject refers to core-4708.
|
|
It was found that explained plan produced by ISQL is unexpectedly ends on WI-V3.0.0.32256.
|
|
This test uses that query, but instead of verifying plan text itself (which can be changed in the future)
|
|
it is sufficient to check only that plan does NOT contain lines with ellipsis or 'truncated' or 'error'.
|
|
This mean that 'expected_stdout' section must be EMPTY. Otherwise expected_stdout will contain info
|
|
about error or invalid plan.
