DML Operations in Stored Function

Hi,
I have used Update Statement in a function. Which is giving an errror (ORA-14551: cannot perform a DML operation inside a query).
Can I use DML operations in a stored function ?
(I need help on locking master/transaction tables, i.e if a one user locks a master another user should not get modify access to the master/transactions).
Thanks
Ramesh Ganji

Someone who obviously din't read my previous post in this thread. You should pay attention, programming is all about the details.
ORA-14551: cannot perform a DML operation inside a query).Then it obviously does more than just "returns a Table Type object". Why are you doing DML in a function?
PLS-00653: aggregate/table functions are not allowed in PL/SQL scopeWe can only call pipelined functions from SQL queries. So you'll have to ditch the DML or make it an autonomous transaction. Be very careful if you adopt the latter approach.

How to write DML operation in a function

Hi
Its very urgent for me.
I am writing DML operation directly in a function and is being called from select statement, it is getting error as "DML Operations cannot be performed inside a query".
How to write a DML operation inside a function.
My objective is to call that function from select statement.
Please help me out.
Thankd

No no no. You're committing after each row! soany
other session running the same query will see the
changes you're making. Your session will equallysee
changes caused by running this query in those
sessions.Other session, yes, but current session will only see
the changes once it has completed the current
statement. Otherwise my "rn" column would not have
gone up sequentially in the above example. it would
have gone
1st row rn = 1 (all rows get updated by 1:-
2,3,4,5,6,7,8,9,10,11)
2nd row rn = 3 (all rows get update by 1:-
3,4,5,6,7,8,9,10,11,12)
3rd row rn = 5 (all rows get update by 1:-
4,5,6,7,8,9,10,11,12,13)
4th row rn = 7 (all rows get update by 1:-
5,6,7,8,9,10,11,12,13,14)
5th row rn = 9 (all rows get update by 1:-
6,7,8,9,10,11,12,13,14,15)
6th row rn = 11 (all rows get update by 1:-
7,8,9,10,11,12,13,14,15,16)
7th row rn = 13 (all rows get update by 1:-
8,9,10,11,12,13,14,15,16,17)
8th row rn = 15 (all rows get update by 1:-
9,10,11,12,13,14,15,16,17,18)
9th row rn = 17 (all rows get update by 1:-
10,11,12,13,14,15,16,17,18,19)
10th row rn = 19 (all rows get update by 1:-
11,12,13,14,15,16,17,18,19,20)
So the fact the commit happens each time the rows get
updated, isn't effecting the currently running select
statement.
No, actually you DO see the other session changes. This is because it is AUTONOMOUS transaction, and this a function.
Test by adding:
create or replace function incvals return number as
pragma autonomous_transaction;
v_val number;
begin
update t set rn = rn + 1;
select max(rn) into v_val from t;
dbms_lock.sleep(1); --add this line
commit;
return v_val;
end;
And test in two sessions.
You will NOT get sequential ascending.
>
Think about the effect of two parallel sessionsboth
running this query at the same time, and ask isthis
sensible?Gawd, no, of course not. Like I said, I'd never use
this sort of thing myself. I'm just wondering what
on earth the OP is trying to achieve.
:)Glad to hear it.

Get the Stored Function Results

If there is DML in my Stored Function ,how to Using View Objects to Select Stored Function Results?
I want to get the Stored Function Results in my jsp.
please give me the example jsp.Thanks!

There's an article on my "Dive into BC4J" weblog that describes this.

Any issue if we writing DML,DDL and TCL commands in stored functions.

Hi,
Is there any issue if we writing DML,DDL and TCL commands in stored function with help of PRAGMA AUTONOMOUS_TRANSACTION.

Hi,
Yes, Ofcourse. Using DML Statements Inside the function using PRAGMA AUTONOMOUS_TRANSACTION is not highly
recommended. It is recommended to use AUTONOMOUS TRANSACTION for error logging purposes only, and
when used in an disorganized way it may lead to dead locks and we will have problem when examining the
Trace Files.

Executing DML-ing stored function from EntityManager

Hi,
Is there some way of getting the result from a DML-ing stored function from the EntityManager? I can use a native query and just select the function from dual if it doesn't do any DML but when it does, it is not permitted. I can't use getDelegate() to get the raw connection either :-/

Date Field Displaying and DML Operations

Hi all,
I have an issue with displaying and updating date columns that I'm hoping someone can assist me with.
I'm using APEX 3.0.1.
I have a Form page with a number of fields sourced from one database table that are being populated by an Automatic Row Fetch On Load - After Header.
The Item P6_MONTHFOR is stored as a Date datatype in the table and displayed on the form using the Date Picker (use Item Format Mask). I have a Format Mask set as 'MON-RR'. I want to ensure that the last day of the month is saved back to the database table so have been trying various calculation techniques to try and achieve this but am experiencing a variety of SQL errors!
I have tried using LAST_DAY(:P6_MONTHFOR) in the Post Calculation Computation, or as a separate Computation After Submit.
I have also tried having P6_MONTHFOR as a hidden column and using display Items and then trying Item calculations to then update the value of P6_MONTHFOR column prior to DML operations but to no avail.
The only DML operations allowed on these rows are DELETE and UPDATE and I'm using an Automatic Row Processing (DML) On Submit - After Computations and Validations process to control these operations.
Any help or suggestions greatly appreciated :-)
Kind Regards,
Gary.

the function LAST_DAY is a date function, expecting a date as input. Since it is all web, the values of items are as string/varchar2. In order to use date-function, you have to first make it a date with to_date() with the format-mask (DD-MON-RR).
In my opinion Dates are still tricky, it would be great if ApEx would have a DV() function, next to the V() and NV() functions, It is in ApExLib (of Patrick Wolf)

Oracle 8i array DML operations with LOB objects

Hi all,
I have a question about Oracle 8i array DML operations with LOB objects, both CLOB and BLOB. With the following statement in mind:
INSERT INTO TABLEX (COL1, COL2) VALUES (:1, :2)
where COL1 is a NUMBER and COL2 is a BLOB, I want to use OCIs array DML functionality to insert multiple records with a single statement execution. I have allocated an array of LOB locators, initialized them with OCIDescriptorAlloc(), and bound them to COL2 where mode is set to OCI_DATA_AT_EXEC and dty (IN) is set to SQLT_BLOB. It is after this where I am getting confused.
To send the LOB data, I have tried using the user-defined callback method, registering the callback function via OCIBindDynamic(). I initialize icbfps arguments as I would if I were dealing with RAW/LONG RAW data. When execution passes from the callback function, I encounter a memory exception within an Oracle dll. Where dvoid **indpp equals 0 and the object is of type RAW/LONG RAW, the function works fine. Is this not a valid methodology for CLOB/BLOB objects?
Next, I tried performing piecewise INSERTs using OCIStmtGetPieceInfo() and OCIStmtSetPieceInfo(). When using this method, I use OCILobWrite() along with a user-defined callback designed for LOBs to send LOB data to the database. Here everything works fine until I exit the user-defined LOB write callback function where an OCI_INVALID_HANDLE error is encountered. I understand that both OCILobWrite() and OCIStmtExecute() return OCI_NEED_DATA. And it does seem to me that the two statements work separately rather than in conjunction with each other. So I rather doubt this is the proper methodology.
As you can see, the correct method has evaded me. I have looked through the OCI LOB samples, but have not found any code that helps answer my question. Oracles OCI documentation has not been of much help either. So if anyone could offer some insight I would greatly appreciate it.

Before 9i, you will have to first insert empty locators using EMPTY_CLOB() inlined in the SQL and using RETURNING clause to return the locator. Then use OCILobWrite to write to the locators in a streamed fashion.
From 9i, you can actually bind a long buffer to each lob position without first inserting an empty locator, retrieving it and then writing to it.

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.

Recursing through table / complex return types in Java Stored Functions

I have a table representing a tree with arbitrary depth, of the form:
ID NUMBER(10) PRIMARY KEY,
NAME VARCHAR2(20),
PARENT NUMBER(10)
with PARENT being a foreign key for ID, so that top-level nodes in the tree have a NULL PARENT, and other nodes have the ID of their parent node in the PARENT field.
I want a good way to get a row representing a node as well as all its ancestor nodes recursively up to the top level. I do this a lot in my Java application, and right now it works by just getting each row, checking if PARENT is null, and recursing again until I get the top-level node. Since this recursion is in Java and I do multiple queries it's rather slow, and I'd rather perform this operation in the database (using a Java Stored Function/Procedure or PL/SQL).
I'm no good at PL/SQL so don't have a clue how to go about doing this sort of thing, and although I can write a Java Stored Function that does the same recursion I do in the application, I don't know how to return the results. I can't return a REF CURSOR type since the results are from multiple queries, and I can't find any documentation about how to return structured types from a JSF.
If anyone could give me a near-complete PL/SQL listing that does this or (better) help me to complete my Java Stored Function by returning the results in a structured type.

You are my own personal God (for the day). Thanks, exactly what I needed, and all in one query with no procedural.

Calling stored function that contains commit from .JCX

I would like to call a stored function (Oracle) that contains a commit, from
a WebLogic database control (.JCX). The suggested way to call a stored
function is to do something like:
* @jc:sql statement::
* SELECT MY_FUNCTION({projectID}, {staffID}) FROM DUAL
int callMyFunction(int projectID, int staffID) throws SQLException;
This doesn't work if the function contains a commit - I get: ORA-14552:
cannot perform a DDL, commit or rollback inside a query or DML. I don't
want to just get my own connection to the db in my code and call it directly
because then I won't be using the connection pool provided by WebLogic. Is
there a recommended way to do this? So far, the database control has taken
care of getting connections from the pool. Can I get a connection from the
pool explicitely and use it? How do I "return" it to the pool?
Thanks.

Thanks for the response.
So far, I've only used the database control, so I haven't been doing any
transaction management (rollbacks/commits) myself - I've just called methods
in my database control and not worried it. Come to think of it, all my
other calls are just SELECTs, so it hasn't been an issue, but I've assumed
WebLogic or the connection pool would take care of transaction management
for me if I coded an UPDATE function in the database control.
What do you mean by "find and use the control API provided for
defining/demarking
transactions" ... what control?
I've seen stuff in the help file about transaction management, so I can
research that, but where do I get the connection to use for this? I'm
thinking I should get it from the pool (rather than create my own
connection). I saw a generated method in my database control called
getConnection, but when I tried using it with a CallableStatement I got
error:
"The transaction is no longer active - status: 'Committed'. No further JDBC
access is allowed within this transaction."This means that you are automatically being taken care of transactionally,
and don't need to do any commit() calls.

I guess it's pretty obvious that I'm pretty new to WebLogic.

How to Track DDL and DML Operations happening in Backend into Log Files....

Hi I have one requirement for Tracking the DDL And DML Operation happening in Backend once the user Inserts or Updates any Table.How to Implement the same can anyone proviode the code for the same.
Ex: I have multiple tables in my database if any user fires the DDL or DML it should make entry in the Log file as
Name of the Table Operation Timestamp
X Insert DD-MM-YYYY HH24:MM:SS
Y Update DD-MM-YYYY HH24:MM:SS
Z Delete DD-MM-YYYY HH24:MM:SS
L Select DD-MM-YYYY HH24:MM:SS
Is it Possible to Develop it through Procedure,Function or Package,please give me Idea,,,,,

Please do not post same question in multiple forum. How to Track DDL and DML Operations happening in Backend into Log Files....
What's wrong with the answers posted in the above forum ? Do you go through the "AUDIT" option as suggested in the above post by various members ?

Cannot perform dml operation inside a query

I have created a function which does some dml opration.
when I use it in a through a transformation operator, and execute the map,
it throws the following error:
cannot perform dml operation inside a query
how to handle this?

Hi,
if you want to execute the dml within a mapping, use the pre or post mapping procress operator. Or use a sql*plus activity in the process flow.

04:01:41 - SQL Error : ORA-14551: cannot perform a DML operation inside a query
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

Two DML operations in one FORALL?

Hi all,
In 11g is it possible to make two dml operations in one Forall loop?
For example:
SQL> create table xx_test (col1 number, col2 number, col3 number);
Table created
SQL> create table xx_test1 (col1 number, col2 number, col3 number);
Table created
SQL> insert into xx_test values(1,2,3);
1 row inserted
SQL> insert into xx_test values(1,2,3);
1 row inserted
SQL> insert into xx_test values(4,5,6);
1 row inserted
SQL> insert into xx_test1 values(6,7,8);
1 row inserted
SQL> declare
2 cursor c is select col1, col2, col3 from xx_test;
3 type t is table of c%rowtype;
4 v t;
5 begin
6   open c;
7 loop
8 fetch c bulk collect into v limit 1000;
9   forall i in 1..v.count
10   update xx_test1
11 set col1 = v(i).col2;
12
13 insert into xx_test1(col1,col2,col3) values(v(i).col1,v(i).col2,v(i).col3);
14
15 exit when c%notfound;
16 end loop;
17
18 end;

PL/SQL: SQL Statement ignoredany ideas? I know that this can be achieved by processing row by row but in my case the cursor retrieves a lot of rows...
Thanks in advance,
Alexander.

Stew, a bulk bind from an OCI client looks as follows:
OCIStmtPrepare()
OCIBindByName()/OCIBindByPos() (binding a host array)
while some-condition loop
fill host array
OCIStmtExecute() (specify the number of elements in array via the iters param)
end loopThe statement is executed once for each array element - according to the OCI guide. So in the case of sending a 100 elements, the statement will be executed (iterated) by Oracle, a 100 times. It however is not exactly clear on how the server-side deals with this execution.
The issue you raised with cursor execution counts, seems to be whether the statement is single statement, or single statement with nested statements.
I have written an OCI client doing the exact same tests as were done in PL/SQL using FORALL in this thread.
If the SQL statement executed is SQL, the cursor that is created is executed only "once" (not exactly true as multiple rows are inserted using a single row DML).
If the statement is PL/SQL, the cursor that is created, is executed "once". So pretty much the same behaviour. However, as this statement contains "nested" SQLs (the actual DML statements), these also need to be parsed and executed as cursors. In which case you see these as being executed a 100 times (once per element in for the bind array).
The issue is whether or not the FORALL DML statement is executed once (as it would appear from the executions column), or not?
It would seem that there is some funky happening (some kind of call optimisation perhaps?) when Oracle deals with an array bind - as the cursor seems to be executed once. But that in fact is not the case as that cursor only inserts a single row. And multiple rows are inserted.
E.g. simplistic example to see how many times the FORALL DML statement is executed:
SQL> create sequence emp_id_seq
2          start with 1
3          increment by 1
4          nocycle
5          nomaxvalue;
Sequence created.
SQL> --// add a PL/SQL user function wrapper for the sequence
SQL> create or replace function GetNextEmpID return number is
2          id      number;
3 begin
4          select emp_id_seq.NextVal into id from dual; --// explicit SQL statement
5          return( id );
6 end;

6          buffer TBuffer;
7 begin
8          open c;
9          loop
10                  fetch c bulk collect into buffer limit 100;
11
12                  forall i in 1..buffer.Count
13                          insert into tab1 values( GetNextEmpID(), buffer(i).ename );
14                  exit when c%NotFound;
15          end loop;
16          close c;
17 end;

6 or sql_text like 'SELECT EMP_ID_SEQ%';
EXECUTIONS SQL_TEXT
        14 SELECT EMP_ID_SEQ.NEXTVAL FROM DUAL
         1 INSERT INTO TAB1 VALUES( GETNEXTEMPID(), :B1So the insert seems to have been executed once. However, the wrapper was called 14 times and its SQL statement was called 14 times. Once per bind array value.
So there do seem to be some kind of optimisation on the Oracle side - however, it does not mean that the FORALL statement is not using bulk/array binding. It is. And that is what the FORALL statement is designed to do.
