URGENT Problem using execute immediate in a procedure ...

Hi all,
I am writing this procedure
create or replace procedure pr_test is
begin
EXECUTE IMMEDIATE 'CREATE or replace view test1 as select * from table_name';
end ;
when I execute this procedure even in the same schema who owns this table it gives me this message.
BEGIN pr_test; END;
ERROR at line 1:
ORA-01031: insufficient privileges
ORA-06512: at "COLIS.PR_TEST", line 3
ORA-06512: at line 1
can any body lets me know the solution????
Thanks in advance
Take Care !

Thank you very much fellows.
But I have reached at this point that one has to have create view privellege explicitly to create view using a dynamic sql statemetn. Actually I could create the view using SQL*Plus and every thing was working fine through SQL*Plus. But I granted the rights of create user from a user having DBA role.
Anyways! Thank you very much for contributing this discussion. I really appreciate it.

Problem using EXECUTE IMMEDIATE

Hi,
I am running the following procedure..
table emp ( empno number,ename varchar2 , dept varchar2 )
CREATE OR REPLACE PROCEDURE Sp_Test11 ( p_dept IN VARCHAR2 )

     EXECUTE IMMEDIATE m_sql_query ;
END Sp_Test11;
I am getting the "Invalid character" error on execute immediate statement when i debug ..
Please guide.

Use RETURN or RETURNING INTO Keywords in execute immediate statement.RETURNING INTO is used with INSERT/UPDATE/DELETE statements when there will be triggers that will populate something on the table after an insert or update etc. e.g. when you insert a new record and you want to return the primary key that is automatically generated from a sequence so you can use it in your code for something else.
If you are SELECTing data then you would use the INTO keyword as Gj demonstrated.

Problem with execute immediate code

I have the following anonymous block:
declare
v_id_char varchar2(50) := '2072018827821663';
trace_flg number := 0;
v_exe_imm varchar2(500) := 'univdb.EML_CAMPUS_200605(v_id_char, trace_flg)';
v_exe_imm2 varchar2(500) := 'univdb.EML_CAMPUS_200605(:v_id_char, :trace_flg)';
begin
--1) execute immediate v_exe_imm;
--2) execute immediate v_exe_imm2 using v_id_char, trace_flg);
univdb.EML_CAMPUS_200605(v_id_char, trace_flg);
end;
The compiled procedure that is getting called is defined like this:
CREATE OR REPLACE PROCEDURE univdb.eml_campus_200605(
hist_str IN VARCHAR2,
trace_flg IN NUMBER := 0) IS ...
As you might expect, when I execute the block without execute immediate it works.
But either of the execute immediate statements results in ORA-00900: invalid SQL statment.
I want to use execute immediate because the procedure that gets called will need to be dynamic.
Help appreciated,
...elsa

For me, thats crude if you have a procedure thats
getting created dynamically.
anyway, you could try a
execute immediate ' begin ' || your_funny_proc || '
end;';But for sure the whole stuff is very error prone.Actually, the procedure itself isn't getting built dynamically, only which procedure to call. It's really quite clever in my opinion.
Anyway, I tried you suggestion:
declare
v_id_char varchar2(50) := '2072018827821663';
trace_flg number := 0;
v_exe_imm varchar2(500) := 'univdb.EML_CAMPUS_200605(v_id_char, trace_flg)';
v_exe_imm2 varchar2(500) := 'univdb.EML_CAMPUS_200605(:v_id_char, :trace_flg)';
begin
execute immediate 'BEGIN ' || v_exe_imm || '; END;';
--execute immediate v_exe_imm2 using v_id_char, trace_flg);
--univdb.EML_CAMPUS_200605(v_id_char, trace_flg);
end;
and got
ORA-06550: line 1, column 32:
PLS-00201: identifier 'V_ID_CHAR' must be declared
Did I misunderstand what you were trying for?

Problem in Update statement using Execute Immediate

Hi All,
I am facing problem in update statement.
I am creating dynamic sql and use "execute immediate" statement to execute a update statement.
But it is not updating any thing there in the table.
I have created a query like :
update_query='Update '|| Table_Name ||' t set t.process_status =''Y'' where t.tid=:A';
Execute immediate update_query using V_Id;
commit;
But it is not updating the table.
I have a question , is execute immediate only does insert and delete?
Thanks

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

Using execute immediate creating a table from another

hi friend i wanted to create a table from a select statement in a pl sql procedure. i am using execute immediate but getting problems with it pls can anyone help me.
here is the query i am using
EXECUTE IMMEDIATE 'CREATE TABLE table_name AS (SELECT * FROM a_view WHERE column_name LIKE '%some_string%');
i need to know if this can be done and if yes how. pls help me its bit urgent too. the schema name is same and the privileges are available to create tables too.

Your syntax is wrong.
If you would use a syntax higlighted editor, it would show.
Yout try to execute a string where another string is embedded. Please use two times single quote or use the 'q' function:
This one is correct:
EXECUTE IMMEDIATE 'CREATE TABLE table_name AS (SELECT * FROM a_view WHERE column_name LIKE ''%some_string%'')';
or this one:
EXECUTE IMMEDIATE q'|CREATE TABLE table_name AS (SELECT * FROM a_view WHERE column_name LIKE '%some_string%')|';
good luck

Using EXECUTE IMMEDIATE with an NVARCHAR2 parameter

Hi everyone,
In the system I'm working on, my stored procedure receives an NVARCHAR2 parameter which contains a complete SQL statement. e.g.
'UPDATE SomeTable SET SomeTable.Value = 0'
I want to be able to execute this dynamically, using EXECUTE IMMEDIATE, but I've encountered a problem where this is apparently not supported (because the string is Unicode).
It is crucial that the string stays as Unicode, because of the data that may possible be baked into the SQL statement, and so casting it off to a VARCHAR2, or changing the parameter type, is not acceptable.
Is there a work-around for this issue? Even if it has a performance hit, it will be better than nothing :)
I've tried something like this;
declare
myVal VARCHAR2(256);
begin
myVal := 'UPDATE SomeTable SET SomeTable.Value = 2';
execute immediate 'BEGIN :x; END;' using myVal;
end;
But I get an error;
"bind variable 'X' not allowed in this context"
Has anyone any ideas?
Thanks for your help,
Chris

uhmm, I'm not sure if this is a valid testcase. the string could still be converted into ascii or we8iso8859p1 or whatever 1byte-character set you want.
What I think you should test is a two-byte character as part of SQL, PL/SQL resp. as in SQL all words are defined you can not enlarge it with a 2byte word. But in PL/SQL you could define your own variable. If this variable name itself contains a 2byte character, I guess it will fail.
(I have used l_vär and l_vér as variable names in my example)
Message was edited by:
Leo Mannhart
According to the PL/SQL Reference Guide PL/SQL consists of:
PL/SQL programs are written as lines of text using a specific set of characters:
Upper- and lower-case letters A .. Z and a .. z
Numerals 0 .. 9
Symbols ( ) + - * / < > = ! ~ ^ ; : . ' @ % , " # $ & _ | { } ? [ ]
Tabs, spaces, and carriage returns
This seems no longer up-to-date as I could define a variable l_vär for instance as long as I use a 1byte char set (like iso8859p1). The same variable name as a n-byte char set like UTF-8 will give an error as my example shows.

CREATE TEMPORARY TABLE USING EXECUTE IMMEDIATE

Hi All,
i have a question,
how can i create a temporary table using EXECUTE IMMEDIATE ??
Like:
CREATE GLOBAL TEMPORARY table new_table as (Select * from old_table);
Thanks,
Edited by: xDeviates on Jun 11, 2012 3:13 PM

It looks like you are approaching the problem incorrectly. As I suggested in Dynamic Select, it sounds like you, at most, want a function that returns a SYS_REFCURSOR (it's still not obvious to me why you would even want/ need to resort to dynamic SQL in the first place)
CREATE OR REPLACE FUNCTION get_dynamic_cursor( p_table_name IN VARCHAR2 )
RETURN sys_refcursor
IS
l_rc sys_refcursor;
BEGIN
OPEN l_rc FOR 'SELECT * FROM ' || dbms_assert.sql_object_name( p_table_name );
RETURN l_rc;
END;which you can then call from your application
SQL> variable rc refcursor;
SQL> exec :rc := get_dynamic_cursor( 'EMP' );

Single quotes problem with execute immediate

Thanks for considering to solve the issue.
[i]Situation:
I am trying to create a procedure to perform a set of operations. As part of that, I am trying to create a table using execute immediate statement. This create table statement has a select sub query where p_LOB3 is the variable for the procedure of datatype varchar2.
Problem :
I need to pass the variable p_LOB3 as single quoted as it is of type Varchar2. Also I need to enclose the entire create table query within single quotes. How do I specify this as it is throwing an error when the PL/SQL engine is parsing the single quotes in the query used twice for different purposes as mention earlier.
Query:
execute immediate'create table test5 as select min(contract_number)as contract_number,contact_id,max(line_of_business) as line_of_business from mytable group by contact_id having min(contract_number) = max(contract_number) and max(Line_of_business) = 'p_LOB3' ';

Thank you Todd,
Is just worked fine.
New issue is: I am not able to put 2 such statements in a single procedure and execute. Before I give parameters to the procedure, PL/SQL engine is actually creating a view of the mytable and naming is as test5, as a result I am not able to create a table as there is a view with the same name.
Right now, the workaround I am using is to create three different procedures to create three such tables. I know this is not a good idea....can you please tell me if there is a better way.
Procedure
CREATE OR REPLACE PROCEDURE SP_CREATE_0_0(p_LOB1 IN varchar2, p_LOB2 IN varchar2)
IS
BEGIN
execute immediate 'create table test5 as select min(contract_number) as
contract_number,contact_id,max(line_of_business) as line_of_business from
mytable group by contact_id having min(contract_number) = max(contract_number)
and max(Line_of_business) = ' ' ' || p_LOB1 || ' ' ' ';
execute immediate 'create table test5 as select min(contract_number) as
contract_number,contact_id,max(line_of_business) as line_of_business from
mytable group by contact_id having min(contract_number) = max(contract_number)

887684 wrote:
ORA-00904: "SUBJECT_OBJ": invalid identifier
ORA-06512: at line 7The problem is that your variable subject_obj is not in scope inside the dynamic SQL you are building. The SQL engine does not know your PL/SQL variable, so it tries to find a column named SUBJECT_OBJ in your SAM1 table.
If you need to use dynamic SQL for this, then you must bind the variable. Something like this:
EXECUTE IMMEDIATE 'insert into op_sample (select id,name,:bind_subject_obj from sam1) ' USING subject_obj;Alternatively you might figure out to use static SQL rather than dynamic SQL (if possible for your project.) In static SQL the PL/SQL engine binds the variables for you automatically.

Edited by: user9213000 on 24-Jan-2013 07:38The standard advice when (ab)using EXECUTE IMMEDIATE is to compose the SQL statement in a single VARCHAR2 variable
Then print the variable before passing it to EXECUTE IMMEDIATE.
COPY the statement & PASTE into sqlplus to validate its correctness.

Create temp table using EXECUTE IMMEDIATE

Is there any performance issue in creating globally temp table
using EXECUTE IMMEDIATE or creating globally temp table from
SQL PLUS.
Any response will be greatly appreciated.

Anish,
Creating tables is likely to be an expensive operation.
Performance issues can only be considered in comparison to
alternatives.
Alternatives include: PLSQL tables, cursors and/or recoding so
that tmp tables are not required. (One of our consultants reckons
that sqlserver temp tables are usually used to get around
limitations in sqlserver, ie slightly more complicated sql
statements could be used instead of simpler sql and temporary
tables).
I would think creating the temp table once during sqlplus would
be cheaper than creating and deleting it repeatedly at run time.
Note that EXECUTE IMMEDIATE may do an implicit commit (dbms_sql
certainly does). This may be got over my using the PRAGMA
AUTONOMOUS_TRANSACTION; direction which places a
procedure/function in a seperate transaction.
