Errors executing Oracle recursive query

Azim Fahmi, THSNet,Inc.

Published: 16 Mar 2004

I'm frequently getting ORA-00604 combined with ORA-01000 (max cursor opens). However, when I checked the code, all the result set and statement objects are closed in the final block (I am using JDBC). The query I am executing is an Oracle recursive query (start with and connect by). Can you tell me what could be wrong and under what circumstances the above error occurs?
It could be that the open_cursors parameter is set to a very low number in init .ora file. The default for this is very low (50). It should be set to 200 or higher.

It could be that even if you are closing the result set you are not closing the SQL statements in your JAVA code.

3. Please ensure that your Enable Connection Pooling if set to yes (for performance reason), is set to no.

Please have your DBA monitor the database and ask to see entries using V$OPEN_CURSORS and V$SYSSTAT data dictionary views.

How to implement a ref cursor called in a stored procedure Expert Brian Peasland explains how and when to implement a ref cursor called in a stored procedure.

CURRENT OF with a RETURNING clause I am using Toad for Oracle to create PL/SQL. I get an ORA-00933. Can I do a CURRENT OF with a RETURNING clause?

ORA-00932 using length function An article on this Web site said the length function could tell me the length of a long datatype column. However, in SQL*Plus I received the following error: "ORA-00932: inconsistent datatypes: expected NUMBER got LONG."

DB exception with two errors I am getting a DB exception with two errors together: "ORA-00604: error occurred at recursive SQL level 2" and "ORA-01000: maximum open cursors exceeded." Does this mean that the error in recursive SQL at level 2 is "maximum open cursors exceeded" or does it mean that one of my queries has caused "maximum open cursors exceeded" and it got detected when the recursive SQL at level 2 was executed?

Maximum open cursors exceeded I've got two procedures in order to insert and append content to a BLOB field. In my code I call these procedures to insert content bigger than 4,000 characters. I call the second procedure add_more( p_text in raw ) in a loop. If the loop is executed too many times I get the message "ORA-01000: maximum open cursors exceeded ORA-06512 esql."
