Regression with INSERT/UPDATE...RETURNING statements in driver version 13
Hi,
Since we've upgraded to PSQLODBC 13 we've noticed inconsistency with what SQLFetch returns when INSERT/UPDATE statement with a RETURNING clause is executed consecutively.
We're using PostgreSQL ANSI Driver with Postgres 13.
The sequence of events as follows, with the results we're seeing in the logs.
We've also attached the complete log files for reference.
1. PREPARE ins_invhisthead statement.
PREPARE upd_invhisthead statement.
2. EXECUTE "BEGIN"
3. EXECUTE upd_invhisthead INTO .... USING .... (Update non-existed Record #1)
(UPDATE Statement) SQLExecute with return code 100 (SQL_NO_DATA_FOUND)
(Expected)
4. EXECUTE ins_invhisthead INTO .... USING .... (Insert Record #1)
(INSERT Statement) SQLExecute with return code 0 (SQL_SUCCESS)
(Expected)
(Retrieve RETURNING value) SQLFetch with return code 0 (SQL_SUCCESS)
(Expected)
5. EXECUTE upd_invhisthead INTO .... USING .... (Update non-existed Record #2)
(UPDATE Statement) SQLExecute with return code 0 (SQL_SUCCESS)
(This should have returns code 100 (SQL_NO_DATA_FOUND))
(Retrieve RETURNING value) SQLFetch with return code 100 (SQL_NO_DATA_FOUND)
(The UPDATE statement should have returns code 0, and the SQLFetch shouldn't be executing here as there is no value to retrieve)
6. EXECUTE ins_invhisthead INTO .... USING .... (Insert Record #2)
(INSERT Statement) SQLExecute with return code 0 (SQL_SUCCESS)
(Expected)
(Retrieve RETURNING value) SQLFetch with return code 0 (SQL_SUCCESS)
(Expected)
7. EXECUTE upd_invhisthead INTO .... USING .... (Update non-existed Record #3)
(UPDATE Statement) SQLExecute with return code 100 (SQL_NO_DATA_FOUND)
(Expected)
8. EXECUTE ins_invhisthead INTO .... USING .... (Insert Record #3)
(INSERT Statement) SQLExecute with return code 0 (SQL_SUCCESS)
(Expected)
(Retrieve RETURNING value) SQLFetch with return code 0 (SQL_SUCCESS)
(Expected)
9. EXECUTE upd_invhisthead INTO .... USING .... (Update Existing Record #2)
(UPDATE Statement) SQLExecute with return code 0 (SQL_SUCCESS)
(Expected)
(Retrieve RETURNING value) SQLFetch with return code 100 (SQL_NO_DATA_FOUND)
(This should have returns the invhisthead_id with return code 0)
10. EXECUTE ins_invhisthead INTO .... USING .... (Insert Record #2)
(INSERT Statement) SQLExecute with return code -1 (SQL_ERROR) ERROR: duplicate key value violates unique constraint "invhead_company_branch_date_cusno_invno_udx
(Expected)
11. EXECUTE "COMMIT"
