Updated tests: cases with bugs or which cannot be run
with the cursor-protocol were excluded with
"--disable_cursor_protocol"/"--enable_cursor_protocol"
Fix for v.10.5
This patch adds for "--ps-protocol" second execution
of queries "SELECT".
Also in this patch it is added ability to disable/enable
(--disable_ps2_protocol/--enable_ps2_protocol) second
execution for "--ps-prototocol" in testcases.
Tests with checking metadata or that cannot be run with
the view-protocol are excluded from --view-protocol.
For tests that do not allow the use of an additional connection,
the util connection is disabled with "--disable_service_connection".
Also cases with bugs for --view-protocol are disabled.
CREATE PROCEDURE did not detect unknown SP variables in assignments like this:
SET var=a_long_var_name_with_a_typo;
The error happened only during the SP execution time, and only of the control
flow reaches the erroneous statement.
Fixing most expressions to detect unknown identifiers.
This includes simple subqueries without tables:
- Query specification: SELECT list, WHERE,
HAVING (inside aggregate functions) clauses, e.g.
SET var= (SELECT unknown_ident+1);
SET var= (SELECT 1 WHERE unknown_identifier);
SET var= (SELECT 1 HAVING SUM(unknown_identifier);
- Table value constructor: VALUES clause, e.g.:
SET var= (VALUES(unknown_ident));
Note, in some more complex subquery cases unknown variables are still not detected
(this will be fixed separately):
- Derived tables:
SET a=(SELECT unknown_ident FROM (SELECT 1 AS alias) t1);
SET res=(SELECT * FROM t1 LEFT OUTER JOIN (SELECT unknown_ident) t2 USING (c1));
- CTE:
SET a=(WITH cte1 (a) AS (SELECT unknown_ident) SELECT * FROM cte1);
SET a=(WITH cte1 (a,b) AS (VALUES (unknown,2),(3,4)) SELECT * FROM cte1);
SET a=(WITH cte1 (a,b) AS (VALUES (1,2),(3,4)) SELECT unknown_ident FROM cte1);
- SELECT .. GROUP BY unknown_identifier
- SELECT .. ORDER BY unknown_identifier
- HAVING with an unknown identifier outside of any aggregate functions:
SELECT .. HAVING unknown_identifier;
