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) ora-01001 invalid cursor for loop 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 As a note, the ORA-01001 error does not exist in Oracle 10g, according to the Oracle documentation.

Execution failed on statement if v_cursor%isopen then close v_cursor; -- here was an error end if; After some digging into I discovered that problem was in subprogram that opened this cursor. I fixed bug by adding output parameter sys_refcursor in subprogram. http://stackoverflow.com/questions/11341166/strange-error-ora-01001-invalid-cursor-in-procedure To clarify situation consider following test code: procedure nested_test(test number, p_cur out sys_refcursor) is procedure nested_procedure_fail is begin open p_cur for select 1, 2, 3, 4 from dual where 1 = 0; end; procedure nested_procedure_success(p_cur out sys_refcursor) is begin open p_cur for select 1, 2, 3, 4 from dual where 1 = 0; end; begin if test = 1 then nested_procedure_fail; else if test = 2 then nested_procedure_success(p_cur => p_cur); else open p_cur for select 6, 7, 8, 9 from dual where 1 = 1; end if; end if; end; procedure test_fail is v_cur sys_refcursor; begin nested_test(test => 1, p_cur => v_cur); if v_cur%isopen then close v_cur; end if; end; procedure test_success is v_cur sys_refcursor; begin nested_test(test => 2, p_cur => v_cur); if v_cur%isopen then close v_cur; end if; end; If I try to run test_success everything is OK, but on test_fail I receive a message ORA-01001: Invalid cursor I cannot find any information about this. Can anyone explain why this code fails?

Oracle. 0 Comments End-to-end performance tuning is something you hear more and more about. I have seen many presentations about how the "modern" DBA has to be http://phlonx.com/blog/fred/index.php/2009/09/25/debugging-ora-01001-invalid-cursor/ intimately concerned with all layers of the application stack and cannot just focus on the database. I'm on board with that, but the reality is, I have rarely seen it http://plsql.globinch.com/ora-01001-invalid-cursor/ in practice. The only time DBAs, developers, and netops folks seem to venture out of their silos is during crisis meetings and in emergency-situation chatrooms. A case in point was invalid cursor when I was asked to troubleshoot an invalid cursor error on a client's database. Here's the helpful documentation Oracle provides for this error: oerr ora 1001
01001, 00000, "invalid cursor"
// *Cause:
// *Action: Hm. I guess that this is one of those things you're just supposed to "know". Actually, invalid cursor is generally a problem with the 01001 invalid cursor application design. Perhaps the code is squandering resources and opening too many cursors. A common solution is to jack up the value of MAXOPENCURSORS. (Note that this is not an Oracle parameter as some people seem to think. It's precompiler option. Meaning that you set this in a C header file and recompile your application in order to change it. But don't ask me about this stuff; I'm a DBA, not a developer, remember?) Well, there was no chance of throwing this problem back on the developers and saying "it's your problem, fix it." The application in this system is a black box, the source code is unavailable, and the vendor who wrote the software is long gone. Must be a pretty sweet time for the developers in this shop; they get to spend their days with their feet up or playing foosball. Thus it was up to us DBA-types to come up with a solution. Where to begin? The error arose when a user of the application tried to change her password through the web interface. Our first thought w
2 ORA-01001: invalid cursor TweetSumoMe Tweet ORA-01001: invalid cursor error occurs when you tried to reference a cursor that does not yet exist. A few scenarios given below. 1. FETCH cursor before opening the cursor. 2. CLOSE cursor before opening the cursor. 3. FETCH cursor after closing the cursor. See the blow example: When you write generic cursor you can either use FETCH..,OPEN… and CLOSE cursor statements Or you can use the FOR LOOP for iterating through the cursor. When you use FOR LOOP for iteration no need of Explicit use of FETCH..,OPEN… and CLOSE cursor statements. The cursor will open automatically when entering FOR LOOP and will close the cursor once the loop ends. Read:Cursor | Oracle PL/SQL Cursors and example. Read:ORA-01000: maximum open cursors exceeded. Read:Oracle Cursors | OPEN ,FETCH and CLOSE Cursor statements. If you use CLOSE statement after the FOR LOOP Oracle will throw the error : ORA-01001:Invalid Cursor See the example below create or replace procedure Param_Cursor as CURSOR PERSON_CUR(pAge NUMBER) is Select * from Person p where p.age = pAge; BEGIN for i in PERSON_CUR(13) loop dbms_output.put_line(i.firstname); end loop; close PERSON_CUR; END Param_Cursor; Execute this: SQL> exec Param_Cursor; begin Param_Cursor; end; ORA-01001: invalid cursor ORA-06512: at "TEST.PARAM_CURSOR", line 10 ORA-06512: at line 1 SQL> Technorati Tags: ORA-01001, CLOSE cursor, open cursor, Fetch cursor, Oracle cursor Be Sociable, Share!
