Since about 1 month we have a database/ODBC error.
Server: ORACLE 188.8.131.52
Client: Windows 7, VB6 SP6, ODBC 12.1 / 12.2 (32-bit)
The error is characterized by
that no error messages are reported by the ODBC driver.
e.g. Query usually ends with the error:
ORA-01427: single-row subquery returns more than one row
Our configuration brings however,
an incomplete result set without notification / error message.
e.g. Constraint injuries in inserts are not reported
but the SQL remains active until the timeout (connection hangs).
We found through tests that a new ODBC driver version (instant_client 18.5) is working correct.
Is there a way to get around this error, without complete driver change?
