ORA-14552: cannot perform a DDL in a execute immediate - proc

Hi All,
I am trying to disable triggers in a stored procedure:
PROCEDURE Alter_trigger_DISBALE
IS
BEGIN
execute immediate ('alter trigger BEI_INS_MY DISABLE');
END;
I get the following error:
ORA-14552: cannot perform a DDL, commit or rollback inside a query or DML
Is there a solution for this problem ?
Best Regards
Friedhold

How are you calling the procedure?
I assume that, since your procedure actually compiles, it doesn't have the parenthesis around the EXCEUTE IMMEDIATE string and that there is a CREATE before the PROCEDURE. I hope that "disable" is spelled correctly in the real thing.

ORA-14552: cannot perform a DDL, commit or rollback inside a query or DML;;

Hi all,
I have a problem!
I have one PL SQL function doing an Update and insert into some oracle tables, this function return one number (0 or 1 or 2).
I'm excuting this query from one PHP program to call the function :
SELECT SALE.DB_FUNC_ASSOCIATE_TB2U('[email protected]',123)
FROM dual;
the problem that I have these errors :
ERROR DB_FUNC_ASSOCIATE_TB2U Level 1 : ORA-01403: no data found
ERROR DB_FUNC_ASSOCIATE_TB2U : ORA-14552: cannot perform a DDL, commit or rollback inside a query or DML
there's a mean that i can do to call this function from PHP without getting this Error such as I tested this function using the script below and it works fine:
declare
a number;
begin
a:= SALE.DB_FUNC_ASSOCIATE_TB2U('[email protected]',123) ;
end;
Please help me :)
regards,

Sure, it works in the sense that you would no longer get an error.
Creating this as an autonomous transaction, however, is going to blow your transactional integrity. You've now got code that is being called as the result of a SELECT operation (something that everyone that comes after you will assume is read-only) that commits outside of the current transaction scope. That is almost always a bad thing.
In addition, having a WHEN OTHERS without a RAISE is almost always a bug. You're completely hiding the error message plus you're discarding proper exception handling in order to provide a return code and assuming that the caller is going to check the status. Relying on return status codes is normally a bad idea because it's very easy on the client side to forget to check the return code. Even if the client were to check the return code, it has no idea what went wrong, so it can't even log the root cause of the error.

this error generates everytime when i run a apex application
i did call the package in session state with dbms_session.set_nls('NLS_LANGUAGE','AMERICAN'); but still it shows the error in the report any solution please

Hi Amrit
Can you put the FND_GLOBAL calls in a pre map trigger/process rather than as part of the map?

ORA-14551: cannot perform a DML operation inside a query

I have a Java method which is deployed as a Oracle function.
This Java method parses a huge XML & populates this data
into a set of database tables.
I have to call this Oracle function in a unix shell script using sqlplus.
Value returned by this function will be used by the shell script to decide
what to do next.
I am calling the Oracle Java function as follows in the shell script:
echo "SELECT XML_TABLES.RUN_XML_LOADER('$P1','$P2','$P3','$P4') FROM DUAL;\n" | sqlplus $DB_USER > $LOG
This gives error - "ORA-14551: cannot perform a DML operation inside a query".
If I have to add a AUTONOMOUS_TRANSACTION pragma to this Java function,
where to I add it considering, that the definition of the function is in a Java class.
Can we do it in call spec?
create or replace package XML_TABLES is
function RUN_XML_LOADER(xmlFile IN VARCHAR2,
xmlType IN VARCHAR2,
outputDir IN VARCHAR2,
logFileDir IN VARCHAR2) RETURN VARCHAR2 AS
LANGUAGE JAVA NAME 'XmlLoader.run
(java.lang.String, java.lang.String, java.lang.String, java.lang.String)
return java.lang.String';
end XML_TABLES;
If not is there any other way to acheive this?
Thanks in advance.
Sunitha.

If I have to add a AUTONOMOUS_TRANSACTION pragma to this Java function,You'd have to write a PL/SQL function that calls the JSP. But I would caution you about using that pragma. It does introduce tremendous complexity into processing.
As I see it you only need a function to return the result code so why not use a procedure with an OUT parameter?
Cheers, APC
Of course Yoann's suggestion of using an anonymous block would work too.

Yes - and the exception is telling you EXACTLY what the problem is. You have a query
IF INSERT_BATCH(99,varSTMT) > 0 THEN
And you are performing a DML operation inside that query:
INSERT INTO BATCH_STATEMENT(QUEUE_ID,TABLE_ID,STATEMENT,QUEUE_SEQUENCE_ID)
    VALUES (numQUEUE_ID,numTABLE_ID,varSQL_STATEMENT,1);
Like the exception says: you can't do that.
You need to call the function using PL/SQL and capture the return value into a variable. Then test that variable:
myVar := INSERT_BATCH(99,varSTMT);
if myVar > 0 THEN

Cannot perform DDL DML inside a query

Hi,
I am using Tom Kyte's in_list function to create a select list inside a select query in one of the reports in my application, given as follows:

If I replace the query passed to function select_list_from_query, with some simple dummy query, then it works fine.
Please tell me is there any limitation of its use as this case?
What may be the possible best solution?

I have tried Scott's parenthesis solution first.
It is working but with making an additional change, i.e., passing '||''''||colon_delimited_list||''''||' instead just ''||colon_delimited_list||''.
Denes, I have also seen your examples, really a helpful resource.
Thank you very much!

Calling procedure from RPD. Error ORA-14552 as it has a commit.

Hi All,
I have implemented the calling of procedure functionality from rpd.
But our data base procedure that is called has commit in it which I guess is not allowed & so we are getting this error.
We need to commit once we finish off the procedure. Please suggest how we can achieve this.

This is we are using from RPD to call the function:
SELECT trailing_cost_function('USD', 'JUN-08', ' POC', '', 'DJRC46', '') AS RET_VAL
FROM dual
Now this is the structure of the function which is in back end db:
CREATE OR REPLACE Function
Trailing_Cost_Function(a IN varchar2,b IN varchar2,c IN varchar2,d IN varchar2,e IN varchar2,
f IN varchar2) return
varchar2 IS
ret_o varchar2(50);
begin
test123; -- calling the procedure
ret_o:='0';
return ret_o;
end;
And the procedure is:
create or replace procedure test123 is
begin
insert into test_123 values ('asssd');
end test123;
Thanks,

SQL Error: ORA-04092: cannot COMMIT in a trigger

Trying to drop the table inside the trigger but i'm unable to do it.
SQL Error: ORA-04092: cannot COMMIT in a trigger
I need to drop the table based on the some condition say condition is the archive table with more than millions of records which is of no use so i plan to drop the table.
I will be inserting the the unwanted table to mytable ,mytable which is having the trigger will fire to drop the table.
I need this to be done on automatic basis so i have chosen trigger.
is there anyway of automatic other than trigger in this case.

is there anyway of automatic other than trigger in this case.You can't COMMIT inside a trigger. Oracle issue an auto COMMIT before and after the execution of DDL. So you can't use DDL in trigger. You may get suggestion to use AUTONOMOUS_TRANSACTION to perform COMMIT within tirgger. But dont do that. Its wrong idea.
I will suggest you look back into your requirement and see what exactly you want. You could schedule a job that runs on a daily basis that will pick up the object details from your table and drop them accordingly.

ORA-00604 and ORA-14552

Hello,
I have an Oracle 10.2.0.1 database and access via sqlplus, toad or applications that use ado for example, is shown the errors ORA-00604-(recursive sql error ocurred at level 1) and ORA-14552 - (can not perform DDL, commit or rolback inside a query or DML) simultaneously. The interesting thing is that is causing intermittent access occurs sometimes but not others. Already checked all datafiles and tablespace structure, but did not identify the source of these errors. These errors occur in access to different schemas, as if the source was some bug or global parameter. What could be causing this?
Thanks.

Would any query in the data dictionary that I could use for self-identifying the source of these errors? In my environment at times though I was logged on the bench when I run some queries it returns the error. It's been two days and am having difficulty self-identifying the problem. Another thing that I could enter the problem is that one of the developers of the application created and modified objects in production base without us knowing. He told us that despite the change there is nothing that could cause errors. We are thinking of stopping the database and start again. This would also be an alternative?

ORA-00604 & ORA-30512 CANNOT MODIFY TABLE MORE THAN ONCE IN A TRANSACTION

What causes "ORA-01445: cannot select ROWID from" error

While executing a SELECT query i got this error:

Below mentioned is the join condition part of the query. The line which the error has occured is italicized

What do i do?

I would rather use Notepad than store my data in SQL server. It just so happens that our product is released for SQL Server as well. Hence i did the testing.
>Is there a limit to the number of joins that can be performed in Oracle?
Wrong question as it does not have anything to do with the number of views.. it has everything to do with the ability to correctly identify the unique row. Re-read the error message details posted by Blu - it explains the error.As you can see from my post, i created a table using the(CTAS) SELECT query from the View vw_ver_master's definition. So the view's result set is now stored in a table and now there are only tables involved in these JOINS.
The query will succeed if i comment out ANY one of these JOINS in this statement. This is so weird.

ORA-02047: cannot join the distributed transaction in progress

Hi All,
My requirement is to do COMMIT Transactions in BULK like 100 rows. I am doing update in Oracle and SQL Server both. Following statement update the SQL Server side:
v_sqlstr :=
'update JDETAIL set interfacedate = getdate() where company ='
|| v_company
|| ' and Recordnumber= '
|| TO_NUMBER (v_recordNumber)
|| ' COMMIT TRANSACTION';
num_rows :=
DBMS_HS_PASSTHROUGH.execute_immediate@ex_test (v_sqlstr);
After this I am calling Oracle Update Procedure . In Oracle UPDATE Procedure when I write AUTONOMOUS TRANSACTIONS AND Commit then it works fine BUT when I don't COMMIT which I don't want because I want to COMMIT in BATCHES then following error is thrown
ORA-02047: cannot join the distributed transaction in progress
Thanks

you can't put the commit transaction into a pasthrough statement.
Oracle Gateway starts the transaction, so you need to write the code in a way that allows the gateway to perform the commit. When doing a commit in a passhrough statement the gateway has no control over the committed data. Thus you get the error unless you start an autonomous transaction.
Why do you need to call the update in a pasthrough statement? Why not in a PL/SQl code block with a counter that commits after 100 rows?

ORA-22990 ( Cannot span lob... ) while using connection pooling...

Hi all, I am maintaining a web site that has lots of requests ( about 10 requests a second ) to an Oracle table that has a BLOB field. Those requests create new blobs, updates them and reads them... My program worked fine until I started using connection pooling ( Before that, I used a single connection that was initialized at startup ). Although I had to synchronized the methods that interact with blob field, everything worked great. So now, to optimize my site, I want to use connection pooling so that even if my methods are synchonized on the connection object, there will be more than one connection available so it will not affect performance.
So once I introduced my connection pooling system with the oracle.jdbc.pool.OracleConnectionCacheImpl class, I started getting ORA-22990 ( Cannot span lob objects... ). I get the error on the flush() method when I try to write the blob to the database. Here is my function that writes a row in the databse.
private synchronized void writeSession(CapSession pSession) throws Exception
        javax.sql.PooledConnection pc = pool.getPooledConnection();
        Connection conn = pc.getConnection();
        CallableStatement stmt=conn.prepareCall(writeObjSQL);
        stmt.setString(1,pSession.getSessionId()+pSession.getPassword());
        stmt.setLong(2,pSession.getLastAccess());
        stmt.setLong(3,pSession.getTimeout());
        stmt.registerOutParameter(4,java.sql.Types.BLOB);
        stmt.executeUpdate();
        oracle.sql.BLOB blob=(BLOB)stmt.getBlob(4);
        OutputStream os=blob.getBinaryOutputStream();
        ObjectOutputStream oop=new ObjectOutputStream(os);
        oop.writeObject(pSession);
        oop.flush();
        oop.close();
        os.close();
        stmt.close();
        conn.commit();
        conn.close();
        pc.close();
} If anyone could help me, I would deeply appreciate it!
Thank you for your time.

Thank you very much for your advice!!!
Like you said, I started to check whether the connections are fine before giving them from the pool.I am executing a simple "select 'anil' from dual" and if its fine only then I return the connection. So far it seems to be fine. Also I am reopening the connections(closing the old ones and opening new connections) after every 12 hours.
As far as the JDBC driver is concerned, I already tried with Oracle 8i driver, it gave the same problems. I read that 9i driver might solve this problem, so I changed to the latest 9i driver (classes12_g.zip).
Sometimes before(before I started checking whether the connection is good )the application used to hang up at the point where I am issuing setAutoCommit(false).It never comes out from that statement.Is this something to do with theconnections being closed?
What I am afraid is, will the appilation get hung up even after I check the connection with select query and then issue autocommit(false)??
Or will it hang up while I check with a select query??
As long as it doesn't hung up, I am fine. Because i am cathching the exceptions.
Thanks In ADVANCE
Anil
