ORA-01001 invalid cursor
Cause: Either a host language program call specified an invalid cursor or the value of the MAXOPENCURSORS option in the precompiler command were too small. All cursors must be opened using the OOPEN call before being referenced in any of the following calls: SQL, DESCRIBE, NAME, DEFINE, BIND, EXEC, FETCH, and CLOSE. The Logon Data Area (LDA) must be defined by using OLON or OLOGON. If the LDA is not defined, this message is issued for the following calls: OPEN, COM, CON, ROL, and LOGOFF.
Action: Check the erroneous call statement. Specify a correct LDA area or open the cursor as required. If there is no problem with the cursor, it may be necessary to increase the MAXOPENCURSORS option value before precompiling.
The ORA-01001 error occurs when:
a host language program call gave an invalid cursor for use
the value of the MAXOPENCURSORS option in the precompiler command was too small
You can fix the ORA-01001 error by:
Check your problematic call statement for any issues
Specify a correct LDA area or open the cursor as required
As a last resort, increase the MAXOPENCURSORS option value before precompiling
