"Invalid Cursor" Error in Form
Hi,
I wrote a procedure that take a REF CURSOR as an IN OUT argument. This procedure does an "OPEN cursor FOR qry" with a dynamic query:
OPEN l_cursor FOR
'SELECT A '||
'FROM B '||
'WHERE C = :l_var'
USING myVar;After calling the procedure, I do a LOOP with FETCH.
It works well when I use it in SQL*Plus with DBMS_OUTPUT but it returns a "ORA-01001 invalid cursor" error in Forms.
Any help is welcome!
Regards,
Olivier.
I found a solution on Metalink:

Invalid Cursor error when modifying Assignment details - Transfer workflow
Hi,
We're trying to submit a Transfer transaction but if we try to modify any field in the Assignment details screen, we're getting a system error, and sometimes we see ORA-01001: invalid cursor error. We have already checked the database objects (procedures, packages, triggers) and we don't see any code which has an invalid use of a cursor. Does anyone have a clue on the cause of this error?This is just a guess,
all you cursors are being opened regardless of any condition, for example;
OPEN CUT(:NEW.LAYOUT_NO);
OPEN DET(:NEW.LAYOUT_NO);
OPEN ITM(:NEW.LAYOUT_NO);
OPEN LOT(:NEW.LAYOUT_NO);
OPEN DTN(:NEW.LAYOUT_NO, :NEW.CUT_NO, :NEW.NOTE);UNA however is opened after a condition;
IF DTN%NOTFOUND THEN
/** start --added for cha 2011-3172 6/14/2011 **/
OPEN UNA(:NEW.LAYOUT_NO, :NEW.ACCOUNT_NO);All cursors arel however closed regardless, i.e. they are all assumes to be open;
CLOSE CUT;
CLOSE DET;
CLOSE DTN;
CLOSE ITM;
CLOSE LOT;
CLOSE STAT;
CLOSE UNA;So I think you are closing the UNA cursors wen it is in fact not open.
So, move the "CLOSE UNA;" line of code to before the END IF; on line 278, since that is when it will definitely be open. -
Getting Invalid Cursor error in a procedure

Is that fine with you???? -
I have a table called cdd_merge_children where the comments field contains the following SQL.
SELECT EVENT_ID FROM EVENT WHERE ACCOUNT_ID = :ACCOUNT_NO
In my procedure I am doing the following:
--get the comments from the cdd_merge_children table where CDD_MERGE_CHILDREN_TYPE
--is of type 3. type 3 are a replica of type 2's for audit/history purposes
SELECT DISTINCT COMMENTS
INTO ls_comments
FROM CDD_MERGE_CHILDREN
where table_name = ps_tablename
and CDD_MERGE_CHILDREN_TYPE = 3 ;
--get the comments from the table and execute the dynamic sql using the looser.
OPEN col_cv FOR ls_comments USING gvloosingaccount ;
--dump the curosr values in the table
FETCH col_cv BULK COLLECT INTO loosingvals ;
For some reason or the other when I try doing the fetch I am getting invalid cursor or ORA-01001: invalid cursor error. WHY WHY
Please help !You cannot bulk-fetch from a cursor into a collection of records, you can only bulk-fetch from a cursor into one or
more collections:
DECLARE
TYPE NameList IS TABLE OF emp.ename%TYPE;
TYPE SalList IS TABLE OF emp.sal%TYPE;
CURSOR c1 IS SELECT ename, sal FROM emp WHERE sal > 1000;
names NameList;
sals SalList;
BEGIN
OPEN c1;
FETCH c1 BULK COLLECT INTO names, sals;
END;
You cannot however,
DECLARE
TYPE NameList IS TABLE OF emp.ename%TYPE;
names NameList;
salary emp.sal%TYPE;
TYPE DeptRecTab IS TABLE OF dept%ROWTYPE;
dept_recs DeptRecTab;
CURSOR c1 IS
SELECT deptno, dname, loc FROM dept WHERE deptno > 10;
BEGIN
SELECT ename, sal BULK COLLECT INTO names, salary; -- illegal target
BEGIN
OPEN c1;
FETCH c1 BULK COLLECT INTO dept_recs; -- illegal
END;
Ok I have a table called cdd_merge_children which has a column called comments. In this column I am storing dynamic SQL such as
SELECT EVENT_ID FROM EVENT WHERE ACCOUNT_ID = :ACCOUNT_NO
Now in my code I retrieve this SQL statement and use it as follows:
--get the comments from the table and execute the dynamic sql using the looser.
OPEN col_cv FOR ls_comments USING gvloosingaccount ;
--col_cv is a reference cursor BTW
--dump the curosr values in the table
FETCH col_cv BULK COLLECT INTO loosingvals ;
Ok at this fetch is where I am getting the following error
ORA-01001: invalid cursor
Why ? Anyhelp would be great

"ORA-01001 Invalid Cursor" error
Platform: oracle 8.X on ibm aix and java client code from
windows NT.
JDBC DRIVER: JDBC Oracle thin driver version 1.2.
when i execute a Sql satement with Cursor expression from the
java client code with XSU it returns an XML DOM But if the
CURSOR EXPRESSION IN THE SQL QUERY RETURNS EMPTY ROWS i get
back an error node with "ORA-01001 Invalid Cursor" error
message.i had aslo set the setNullAttributes(true) property
on oraclexmlquery.
Interestingly, if i exceute the same query in the SQL plus
it returns the column names with no rows.
is there any way where i can get xml document with table
structure, when there are no rows instead of ORA error message.
This is just a guess,

OPEN CUT(:NEW.LAYOUT_NO);

Database selection with Invalid Cursor error in RSDRI_INFOPROV_READ
Hi Everyone.
I am using RSDRI_INFOPROV_READ Function module for reading data from a multiprovider.
Logic of the code is as following
while <more data>
CALL RSDRI_INFOPROV_READ reading data in E_T_DATA
Append lines of E_T_DATA to EO_T_DATA.
If total lines of data in EO_T_DATA > 200000
<save EO_T_DATA in a file using GUI_DOWNLOAD>
<clear EO_T_DATA>
EndIF
EndWhile.
As soon as number of record exceed 200000 first file is saved, but after that next data call results in error.
Error says "Database selection with invalid cursor".
I suspect that this because of call to FM GUI_DOWNLOAD. While calling this FM after RSDRI_INFOPROV_READ causes system to commit and again the cursor is tried to open in next call casuing it to fail.
But it is imperative for me to save data in file at regular intervals as data volume is huge.
Any pointers in this direction will be helpful.Hi Everyone.

Oracle 10g EE Export Results in ORA-01001: invalid cursor Error
Hi,
I'm quite new to Oracle 10g and OCS10g. We have a crippled/corrupt SYSAUX tablespace (data file 3) which cannot be recovered using recover
command anymore. So metalink support instructed us to do a export of the metadata of the working tablespace which contains our system data (we are in configuration stage for OCS 10g 10.1.2) via transportable tablespaces so that I can just recreate the database in DBCA and import the metadata. So after I made a cold backup, set the "transportable" tablespaces to "READ ONLY" mode, I proceeded w/ the export command which resulted in an error, please see below:
$exp \'sys/********@ocs10gSID as sysdba\' parfile=transport.par

Anyone encountered this problem before? Any recommendations or tips to get this working?
I checked this url:"http://luhartma.blogspot.com/2006/05/how-to-check-if-tablespace-is.html"
And when I try to follow the instructions and check on of the tablespace I set to and verified to be in "READ ONLY" mode, I get the same error.

Thanks in advance.

-KenthHi,
The status is "RECOVER" we have actually tried to recover but unfortunately the archive logs that were needed were on disks and were lost during one of the server hardware failures. Actually that is the reason why metalink support recommended this route for getting everything in order since we don't have any application data in SYSAUX yet.
Thanks. -
Invalid number error with Form on table page
We used the "Form on Table..." wizard to create a simple page to update the SCOTT.EMP table. When we submit the page we get the ORA-01722: invalid number error. When I view the data in the WWV_FLOW_DATA view in the FLOWS_010500 schema, I can see all the data from our form in long format with the actual values that were submitted. But I can not track down where this error is coming from.
James,
What data did you enter in each field? Could it be as simple as you tried to enter character data into the deptno column?

Unexpected "ORA-01001: invalid cursor" error
I have a Pro*C application that basically fetches from a cursor, does a bunch of work with that row, does a "delete from <table> where current of <cursor name>", then loops back, fetches, the next row, etc., and finally closes the cursor once all the rows have been processed.
One of our clients is getting an 'ORA-01001' error on the "DELETE FROM <table> WHERE CURRENT OF <cursor>" statement. This is long-standing, frequently executed code at 100+ clients and I've never had a problem with this statement before. The client is consistently getting this error on a particular row from this cursor, but other rows processed with the same cursor are processing successfully.
Unfortunately, I do not have direct access to the client's database, so I cannot debug directly, but I've placed print statements around the only place in my application's code that explicitly closes the cursor. A log generated on a run that threw the 1001 error confirmed that the cursor is NOT being explicitly closed by my application by an "EXEC SQL CLOSE <cursor>" statement.
Likewise, I put print statements around all the COMMITs and ROLLBACKs in my application, and none of these showed in the logs either.
My application does make a call to a client-customized PL/SQL function that they recently changed. However, I have a copy of the clients function and there are not any explicit COMMIT, ROLLBACK, ANALYZE, ALTER, DROP, REPLACE, TRUNCATE or CREATE statements that would implicitly commit and close the cursor.
Here are potential problems that I have ruled out:
-Oracle OPEN_CURSORS parameter - It appears that if this were the problem, the error would be an ORA-1000, not 1001. Please correct me if I am wrong here.
-Pro*C MAXOPENCURSORS parameter - I compiled a version with a MAXOPENCURSORS value that is higher than the client's OPEN_CURSORS setting. If this were the problem, the error should have switched to the ORA-1000 error when I increased the parameter. It remained as an ORA-1001.
Next steps:
-What could cause a cursor to close other than explicit COMMIT, ROLLBACK, ANALYZE, ALTER, DROP, REPLACE, TRUNCATE or CREATE statements?
-Is there anything I can run, such as a database trace, that will show me exactly when the cursor is being closed? I admittedly don't know a lot about DB traces.
-Anything else I should check? Any other information I should provide?
Thanks ahead of time for any help!Chandrakaanth Ramamurthy wrote:
Does the client customized PL/SQL block contain EXIT
Exit will end up issuing a commit and hence this could be an issue.Exit is not used in the customized function.
Chandrakaanth Ramamurthy wrote:
Also please check that commit and roll back are placed at the end of the loop.The only commit/rollback is after the loop is over is finished.
I actually just figured out the issue. Turns out the cursor just hadn't been opened due to a very unique data condition... facepalm You know what happens when you assume things, right? :)
Thanks for the help anyway! -
Payables Open Interface Purge completes with error "Invalid Cursor"
Hello,
I'm trying to run Payables Open Interface Purge (version 115.8) and get an invalid cursor error in the beforereport trigger. Does anyone know the cause and remedy of this? A portion of the log is below. I've looked at the cursor and everything looks fine to me.

Steve,
Were you ever able to look at this item? In the meantime, my work around was to do a separate xsql query for each sub-query(cursor) and then append nodes in my DOM as I went along. But, I would like to help this tool be better. I think I have determined that if one of the sub-select/sub-cursor queries doesn't return anything, I get the "invalid cursor" error. Does that make sense to you? I think that if a the result should still be a blank node
( </NODE> ). What do you think?
thanks,
chad.

I attached two files:
1. file with sql script - you'll have to change the schema.
2. file with code. Two sections
a. 1st with jdbc result set code
b. 2nd with OracleXMLQuery
I comment out one or the other code section to run one or the other.
If you need any other information, please let me know.

| |
| | (1) Does the problem occur if you do a simple query like:
| |
| | SELECT body FROM table
| |

| |
| | (2) Or does it only happen in combination with CURSOR() ?

| | | Hello Steve,
| | |
| | | First I want to thank-you for all of the support you put into Oracle's
| XML
| | | board. I just ordered your book from Fatbrain and it's on back order!
| I
| | | tried asking my question on the board and didn't have any luck getting
| any
| | | responses - maybe people didn't understand my question. I'm desperate
| for
| | | this to work and really need some guidance.
| | |
| | | I'm using the command line to extract data from tables to XML
| | | (.bin\xsql\bin\xsql healthwise.xsql chad.xml). Everything works
| | wonderfully
| | | until I add a LONG data type to the mix. Here is my xsql before the
| LONG:
| | |
| | | <?xml version="1.0"?>
| | | <!-- healthwise_xslt.xsql -->
| | | <xsql:query
| | | xmlns:xsql="urn:oracle-xsql"
| | | connection="healthwise_dev2"
| | | max-rows="22050" >
| | |
| | | SELECT hwp.publish_document_id, hwp.topic_id, hwp.section_id,
| | | CURSOR( SELECT hws.name as section_name
| | | FROM health.section hws
| | | WHERE hwp.section_id = hws.section_id) as section,
| | | CURSOR( SELECT hwk.name as keyword_name
| | | FRO M health.keyword hwk, health.map_keyword_object
| | | hwmko, health.object hwo
| | | WHERE (hwp.publish_document_id =
| | | hwo.publish_document_id) and
| | | (hwo.object_id = hwmko.object_id) and
| | | (hwmko.keyword_id = hwk.keyword_id) ) as keywords,
| | | CURSOR( SELECT hwt.name as topic_name,
| | | CURSOR( SELECT hwts.name as topic_synonym_name
| | | FROM health.topic_synonym hwts
| | | WHERE hwt.topic_id = hwts.topic_id) as
| | | topic_synonyms,
| | | CURSOR( SELECT hwc.name as catagory_name
| | | FROM health.category hwc,
| | health.map_category_topic
| | | hwmct
| | | WHERE (hwt.topic_id = hwmct.topic_id) and
| | | (hwmct.category_id = hwc.category_id) ) as catagories
| | | FROM health.topic hwt
| | | WHERE hwp.topic_id = hwt.topic_id) as topic
| | | FROM health.publish_document hwp
| | | WHERE hwp.publish_document_id IN (13729, 1033, 11695)
| | | </xsql:query>
| | |
| | |
| | | I'm using this in combination with a XSLT and get this output -

| | | </xsql:query>
| | |
| | |
| | | Do I have to pull this out into code and stream the long into a string

nullJust wanted to post Steve's response to this question, in case others have problems with LONG data types and CURSORS in their .xsql queries (thanks Steve!):
I can reproduce the problem with your testcase.
I've filed Bug Number 1472008.
You can workaround the problem by using CLOB
instead of LONG in your table.
You can use to TO_LOB() function in a CREATE TABLE...AS SELECT...
or in an INSERT INTO TABLE...SELECT... to easily
convert existing LONG content into CLOBs.
