Execute Immediat for Cursor

Dear all
can i use Execute Immediate For a Cursor..
for example :-
create or replace procedure P_MAPPING(iaap_name varchar2)
IS
CUR_C1 varchar2(200);
CUR_C2 varchar2(200);
Cur_c1 := 'cursor C1 is
             select recid, xmlrecord
             from'|| OSRC_TAB;   *---Here How can i pass the value which i am getting from the Procedure Below(P_PAPULATE_TAB)*
Cur_c2 := 'Cursor C2 is
           Select column_name,Seq_no
           from TMP_MAP_TAB2
           Where Appl_name = '||ODEST_TAB;*---Here How can i pass the value which i am getting from the Procedure Below(P_PAPULATE_TAB_)*
   Type array_type IS TABLE of varchar2(1000) index by binary_integer;
   OSRC_TAB varchar2(100);
   ODEST_TAB varchar2(100);
begin
P_PAPULATE_TAB(IAAP_NAME,OSRC_TAB,ODEST_TAB);
execute immediate CUR_C1 using OSRC_TAB;
execute immediate CUR_C2 using ODEST_TAB;I want to pass the OSRC_TAB,ODEST_TAB which ore the OUT parameters in the procedure In the Cursor..
Is it possible ?

Hi,
You can try this using sys_refcursor as like below
cur_c1 VARCHAR2(200);
cur_c2 VARCHAR2(200);
osrc_tab VARCHAR2(100);
odest_tab VARCHAR2(100);
l_sys_ref_1 sys_refcursor;
l_sys_ref_2 sys_refcursor;
BEGIN
P_PAPULATE_TAB(IAAP_NAME,OSRC_TAB,ODEST_TAB);
cur_c1 := 'SELECT recid, xmlrecord
FROM'|| osrc_tab;
cur_c2 := ' SELECT column_name,Seq_no
FROM tmp_map_tab2
WHERE appl_name = '||odest_tab;
OPEN l_sys_ref_1
FOR cur_c1;
OPEN l_sys_ref_2
FOR cur_c2;
Thanks

Using EXECUTE IMMEDIATE for DML

What benefit is there to use EXECUTE IMMEDIATE for an UPDATE statement like the one below.
EXECUTE IMMEDIATE 'UPDATE mytable SET bonus = v_bonus(i)
                   WHERE empid =:empid AND sal =:sal'
                          USING v_empid(n),v_sal(i);This UPDATE sql is not dynamically created. So is there any performance benefit associated with using
EXECUTE IMMEDIATE for this UPDATE? Can't i just use a normal UPDATE without EXECUTE IMMEDIATE?

By wrapping the procedure call in a dynamically created anonymous block, you are incurring LOTS of overhead.

Execute immediate for stored procedure with out parameter

Hi,
I have problem with dynamically executing the statement hope anyone can help me.
I have a table which stores the procedure names. and procedure parameter values are stored on another column with parameter values coming from java side.
I have to create a procedure that dynamically executes the procedure on table1 with the values from table 2.
Now I'm getting real trouble to execute immediate this proc with parameters. I tried the DBMS_SQL package as well.
Problem is you need to mention the OUT mode specifically for the out parameter. Can anybody plz help me with this issue??
TABLE1_

Why not have your Java just call the correct procedures directly?
Such design smells badly of an entity attribute value modelling style of coding. Notoriously slow, notoriously buggy, notoriously hard to maintain, notoriously hard to read. It really shouldn't be done like that.

Using execute immediate for select

Hi all,
i am writing a procedure as follows:
create or replace procedure ( run_yr_mo in number) as

this is returning me an error at the execute immediate.
run_yr_mo = 200912
Can someone help me out with this.
Thanks

Just to show it working:

Need suggestion on PLSQL Create and EXECUTE IMMEDIATE

Most of you already know plsql doesn't like create table, so we have to use EXECUTE IMMEDIATE for creating table. What if I want to see if the table exist, if not then create the table, later I will insert data into that table.
My problem is it returned me the error saying I am try to insert into a non existing table when trying to compile my code. I think plsql doesn't pick up the execute statement.
what I did is, both create and insert are executed by using EXECUTE IMMEDIATE. Anyone have such experience before and willing to share your knowledge?
PS: I am having same problem for creating sequence as well.

I think plsql doesn't pick up the execute statement.Since it is a runtime instruction, it will pick it up at runtime. but to be able to run, it needs to compile the code and in order to compile (so it can run) the code it needs that table/sequence you are referencing to exist already. So, you need to run the code to get the table and run needs to compile the code and compile needs the table to compile. can't go from here to there when you try to mix dynamic sql with static sql on the same object within the same program unit (or dependent units).

Execute Immediate in Oracle 10g

Hi , I have a small doubt regarding execute immediate.
As per my knowledge we use execute immediate for writing DDL(create,truncate,...) statements to execute in the procedure or function.
But i have seen in my organization , some of the senior people(already left organization) used to write inserts , updates , deletes also in execute immediate even there is not much dynamic logic involved.
But as per my knowledge execute immediate can be badly used by most of the hackers with SQL injection I guess!!!!!
Is there any reason that they use execute immediate instead of writing the code directly??? Or is there any advantage in writing like this.???

Using execute immediate to create tables and other DDL is fundamentally undesirable, and should be avoided at all cost.
The use of execute immediate you seem to outline, should be avoided too. Apparently those seniors were unaware of the goal of PL/SQL and the disadvantage of execute immediate.
If I could vote to remove execute immediate from PL/SQL, I would be immediately in favor, especially in packages, procedures and functions,as they are stored, which means pre-compiled.

Hi,
If you tried to run this command from PL/SQL
SQL> EXEC PkgTest.test_proc;
do you understand why it would fail? It fails in EXECUTE IMMEDIATE for the same reason.
When you use EXECUTE IMMEDIATE, Oracle runs the dynamic command in a new, separate environment. It knows nothing about the context from which it was called. In particular, it doesn't know if it was called from inside a package or not, so procedures that are private to that package can't be called.
Do you really need to use EXECUTE IMMEDIATE? You obviously don't in the simple test scenario you posted, but I assume your real package is much more complicated.
Why not simply include test_proc in the package spec?
Is the problem that end users, who are allowed to cal run_proc, are not supposed to call test_proc direrctly? If so, put them in different pacakges. Declare test_proc in the spec of its package, but don't grant privileges on the package that end users.

EXECUTE IMMEDIATE within Procedure doesn't work!!

Hi,
I have a code in which the procedure is successfully created, but when I try to check if the table TEST_TABLE is created (ex, DESC TEST_TABLE) it generates an error:
ORA-04043: object TEST_TABLE does not exist
Which means that my EXECUTE IMMEDIATE didn't work within the procedure for some reason, while it works perfectly alone without the procedure!!
Hope you help me with this..
Here's the my code:
CREATE OR REPLACE PROCEDURE TEST_IMM1
AS
BEGIN
EXECUTE IMMEDIATE ' CREATE TABLE TEST_TABLE (ITEM_DESC VARCHAR2(10))';
END;
--Procedure created.

Can you tell me how to use INSERT with EXECUTE IMMEDIATE.
Thanks :)Just as an FYI, this is really not a good methodology to program in Oracle. If you're doing this for purely learning purposes then it's less 'bad', but if you plan on programming as a career in Oracle, this isn't the method you'd want to adopt (i'll not say there is NEVER a case for something like this, but it's a small percentage of the typical use cases).
You would do better to create a global temporary table if you need a table to muck around with in a session, or create a permanent table (likely not via procedures) and have it persist in the schema of your choice.
Utilizing execute immediate for insert statements, especially without BIND VARIABLES, will create a sad day for your database.

Difference between regular update and update with execute immediate

Hi everyone, I have seen some code where developers have executed insert and update statement using execute immediate.
for example :
execute immediate ('Update employees set employee_salary = :x');
I can update record using the following statement where x is a number (salary)
update employee
set employee_salary = x;
It works fine as well
Whats the difference? and what way is recommended
Thanks

Creating cursor using Execute immediate

I am trying to create one cursor using a for loop, but I am not able to do so, could you please help me with the approach to get it done.
Here is the scenario:
I have one table table_1,it contains 2 columns source_query , target_query.
source_query and target_query are Select statements like source_query is Select name, age , valid from customer where customer_id=123456;
I fetched the data from these columns into 2 strings
select source_query into source_data from table_1;
select target_query into target_data from table_1;
Now out of these 2 I want to create 2 cursors, so that I can compare the column values one by one ( I am not using the source minus target approach because of difference in the data type).
I have to individually check the values.
So here are the cursors:
For source_data_value in ( EXECUTE immediate source_data)
LOOP
For target_data_value in (EXECUTE IMMEDIATE target_data)
LOOP
<executable statements>;
END LOOP;
END LOOP;
But the cursor creation is failing in the procedure.
Please let me know if it is possible to create a cursor using the execute immediate , if not what approach I should use other than this?

Why exactly you are doing this inside a procedure. You can take the SQL's out and write a simple query to retrieve the data. Anyways, to work it out in a procedure, I can think of the below solution. I am trying to do away with Execute Immediate and use REF cursor. Please note that this is untested and just a try to present a possible solution which can be changed to implement your original requirement. I haven't done anything sort of this before, so if this approach doesn't approach, kindly ignore
DECLARE
   TYPE TempTyp IS REF CURSOR;
   temp_cv   TempTyp;
temp_cv_2 Temptyp;
   emp_rec emp%ROWTYPE;
   source_data VARCHAR2(200);
     target_data VARCHAR2(200);
   BEGIN
   source_data:= 'SELECT * FROM source tablej';
   target_Date :='select * from target table';
   OPEN temp_cv FOR source_data;
   LOOP
      FETCH temp_cv INTO emp_rec;
      EXIT WHEN emp_cv%NOTFOUND;
        OPEN   temp_cv_2 FOR target_data;
          FETCH Temp_cv_2 into emp_rec emp%ROWTYPE
               loop
                    < And then your comparisons here >
     END LOOP:
     CLOST TEMP_CV_2;
   END LOOP;
   CLOSE temp_cv;

How to use Execute Immediate to execute a procedure and return a cursor?

The procedure name is unknown until run time so I have to use Execute immediate to execute the procedure, the procedure return a cursor, but I can't figure out the right syntax to pass the cursor out.
To simplify the issue here, I create two procedures as examples.Assume I have a procedure called XDTest:
     p_cur OUT SYS_REFCURSOR
IS
BEGIN
OPEN p_cur FOR
Select * from dummy_table;
END XDTest;
In another procedure, I want to use Execute Immediate to execute XDTest and obtain the result that return from the cursor into a local cursor so I can process the records:
     p_cur OUT SYS_REFCURSOR
IS
l_cur SYS_REFCURSOR;
BEGIN
execute immediate 'BEGIN XDTest (:1); END;' using OUT l_cur;
END XDTest2;
However, this is not working, I get ORA-03113: end-of-file on communication channel error.
What syntax should I use here?
Cheers

well...
I update the XDTest2 procedure as below but when execute it get exceptions.I think the v_sqlstmt syntax is wrong, but I don't know what meant to be correct, please give some suggestions .
Cheers

     p_cur OUT SYS_REFCURSOR

Equivalent for execute immediate command in maxdb

hi all,
like in oracle for executing the sql_query, we have execute immediate command.
for e.g.. in oracle
L_SQL ='SELECT * FROM EMP';
EXECUTE IMMEDIATE L_SQL;
what will be the command for execute immediate in MaxDB??
like in MaxDB
L_SQL = 'SELECT * FROM EMP';
Now How can i execute the above l_sql variable in MaxDB.
thanks, Bhupinder

Hi Bhupinder,
the following code snippet should do the job
[code]
CREATE DBPROC EXAMPLE
AS
VAR statement1 char(100);
SET statement1 = 'SELECT * from DBA.DUAL';
TRY
EXECUTE statement1;
CATCH IF $rc <> 100
THEN STOP ($rc, 'unexpected error');
[/code]
Best regards,
Marco

How to pass a sequence by 'using' for execute immediate

how i can pass a sequence.nxlval as a parameter through using , here is my code looks like
sql_string is -> insert into some_tab (col1,col2, ....) (select col1,:passed_seq,......) where .... (i want to insert sequence values for col2)
and i am calling this as
passed_seq := 'seq_'||some_dynamic_num||'.nextval' ( in my db there will be sequences with the formed string like seq_10.nextval)
EXECUTE IMMEDIATE sql_string using passes_seq;
if i am doing like this i am getting
Error : -1722:ORA-01722: invalid number seq_10.nextval

Hi,
I hope you have created sequence as below
SQL>
SQL> CREATE SEQUENCE seq
2 MINVALUE 1
3 START WITH     1
4 INCREMENT BY   1
5 NOCACHE
6 NOCYCLE;
Sequence created.
SQL>
SQL> SELECT * FROM TEST1;
     EMPNO EMPTYPE              EMP_ADDRESS              SALARY     DEPTNO
         1 HR                   MUMBAI                    10000         10
         2 ADMIN                THANE                      6000         20
SQL>
SQL> INSERT INTO TEST1 (EMPNO)
2 VALUES(SEQ.NEXTVAL);
1 row created.
SQL> COMMIT;
Commit complete.
SQL> SELECT * fROM TEST1;
     EMPNO EMPTYPE              EMP_ADDRESS              SALARY     DEPTNO
         1 HR                   MUMBAI                    10000         10
         2 ADMIN                THANE                      6000         20
         1
SQL>Now if you need to add different numbe in differenct condition then create multiple sequence and use them accounding.
