Developer 6.0 doesn't like EXECUTE IMMEDIATE
I am trying to use the EXECUTE IMMEDIATE command in a WHEN-NEW-RECORD-INSTANCE trigger. However, no matter what I do, I get the following error when I try to compile the trigger:
Encountered the symbol "IMMEDIATE" when expecting one of the following:
:= . ( @ % ;
The symbol ":= was inserted before "IMMEDIATE" to continue.
My syntax looks good--I don't know what the problem is
EXECUTE IMMEDIATE , the native dynamic SQL is a feature available only from pl/sql version 8.1.5 . But forms6i is still using pl/sql engin 8.0.6. SO you can create stored procedures ( because Oracle 8i - pl/sql version -8.1.5) and call it in your forms.

Disadvantage with 'Execute Immediate'
What is the disadvantage with 'EXECUTE IMMEDIATE'.
I think you guys are missing the point here.
None of the issues listed are 'EXECUTE IMMEDIATE' disadvantages.
'EXECUTE IMMEDIATE' is a tool. Like DMS_SQL. Like ref cursors. Like explicit cursor. Like implicit cursors.
A tool, any tool, needs to be used correctly. If you use a hammer and hit a nail so hard that it bents, causing the hammer to slip doing some serious damage to your thumb... whose fault it is?
Is it The Hammer that is at fault here? Or is the user of that tool?
There are no disadvantages to using 'EXECUTE IMMEDIATE'. It is a tool. But like all tools it needs to be used correctly and safely. Things like excessive hard parsing because of a severe lack of bind variables, or opening a hole for SQL injection, etc.. all these are symptoms of - and let's be blunt here - an ignorant developer. It has nothing to do with the tool 'EXECUTE IMMEDIATE'.
And those same type of errors will be made by Mr Ignorant Developer using other tools in Oracle.
Shoddy workmanship is not because of poor tools. Shoddy code is not because of using a specific feature (like execute immediate).
The proper question to ask is thus not "what are the disadvantages of execute immediate", but rather "where should I typically use execute immediate and how?".
Not every developer will know how to use every single tool in the toolbox (I sure don't know all the tools in the Oracle toolbox). So there is nothing wrong with asking.
But asking what is "wrong" with a tool (aka "what are the disadvantages") is in my view seriously missing the point that a tool is there to solve very specific types of problems...
That is what a developer should be after - How to use the tool correctly. -
Hi,
for instance, we have 4 parameters for that, i remember we should use each parameter ONLY ONCE within the statement. am i right? Or we can reuse each parameter again and again?
like
execute immediate 'select ...
where :4=''a''
and :4<>'' '''
Rgds,
HuaMinUnfortunately I don't think so you can reuse the same parameter.

Unable to INSERT PL/SQL record with EXECUTE IMMEDIATE
Hi All,
I am selecting data from a source table and after some modification inserting into a target table. Source and target table name are available at run time. You can say only source table structure is fixed.
I have crated a pl/sql table of type source record and inserting record by record in target table using execute immediate. But I am not able to write
EXECUTE IMMEDIATE string USING pl_sql_table(index); and getting error as
PLS-00457: expressions have to be of SQL types
Please see the part of code below. Is it possible to use FORALL with dynamic sql like
FORALL pl_sql_table.FIRST .. pl_sql_table.COUNT
EXECUTE IMMEDIATE .... pl_sql_table(j); -- Like this.
Please suggest why I am not able to write record here. I also want to replace 'INSERT in a loop' with a single INSERT statement out of the loop, to upload whole pl_sql table into target table in one go.
Thanks,
Ravi

How to make my Execute Immediate statement to work??
Hi, Sir:
I use SQL Oracle 9i,
I have following procedure called by a trigger:
CREATE OR REPLACE PROCEDURE emps_check IS
s_sql VARCHAR2(500);
BEGIN
DBMS_OUTPUT.PUT_LINE('1. Start to Delete all rows in the emps' );
delete from emps;
DBMS_OUTPUT.PUT_LINE('2. Start to insert into emps from emp' );
s_sql:='INSERT INTO Emps(EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,COMM,DEPTNO) select EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,COMM,DEPTNO from emp;';
DBMS_OUTPUT.PUT_LINE('3. s_sql= ' || s_sql );
EXECUTE IMMEDIATE s_sql;
DBMS_OUTPUT.PUT_LINE('3. Procedure call OK, Employ Name ' );
EXCEPTION
-- Use this to trap the ORA-00942: table or view does not exist
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE('Procedure call Exception: Employ Name ' );
end emps_check;
My trigger is:
CREATE OR REPLACE TRIGGER emps_biu_after
after INSERT OR UPDATE or delete on emp
for each row
begin
if TO_CHAR(SYSDate,'DY')= 'SUN'
then
DBMS_OUTPUT.PUT_LINE('Today is holiday, ename =' );
else
DBMS_OUTPUT.PUT_LINE('Today is working Day, ename =');
emps_check();
end if;
end;
When I use following to update emp table:
SQL> UPDATE emp T1
2 SET T1.sal = 200.0
3 WHERE T1.ename like '%SCOTT%';
I got:
Today is working Day, Trigger Call Procedure emps_check()
1. Start to Delete all rows in the emps
2. Start to insert into emps from emp
3. s_sql= INSERT INTO Emps(EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,COMM,DEPTNO) select EMPNO,ENAME,JOB,MGR
Procedure call Exception: Employ Name

Looks like EXECUTE IMMEDIATE s_sql; did not work.
What is wrong??

EXECUTE IMMEDIATE with an update FUNCTION returning VARCHAR2
I need to execute immediate a stored Function (that updates the database) and returns a VARCHAR2 value.
What does my execute immediate statement look like:
EXECUTE IMMEDIATE 'BEGIN my_function_call; END;' RETURNING INTO return_variable;A set of procedures would be far preferable to a set of functions if you're doing DML.
Additionally, I'd get rid of the status value entirely and just raise an exception if there is an error. It's a heck of a lot easier to catch (or propagate) exceptions correctly than to ensure that each and every piece of code that calls these procedures checks the return code and acts appropriately. It's way too easy to miss/ hide an error in a missed return code.

Hi,
I want to know if it's possible to use the return clause with the insert statement with EXECUTE IMMEDIATE.
My code looks like:
execute immediate('INSERT INTO '||p_nameDB||'.TableName (col1) VALUES (:1)
') using p_col1;
The id is generated automatically with a trigger (and a sequence). And I want to recuperate it in a variable after the insert statement. I don't want to do a seq.currval after because i'm afraid that there will be a mix match with the sequence and the id if 2 persons accede at the same time.
thanksexecute immediate 'insert into trial (a) values (:1) returning a into :2' using a1 returning into x ;

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..

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. -
How to execute a statement in forms procedure like SQL EXECUTE IMMEDIATE
Hi to all,
In a form I have created this procedure:
PROCEDURE insert_rows (
tbName IN VARCHAR2,
list_of_fields IN VARCHAR2,
origin_table IN VARCHAR2,
wCondition IN VARCHAR2 DEFAULT NULL)
IS
where_clause VARCHAR2 (2000) := ' WHERE ' || wCondition ;
table_to_fill VARCHAR2 (30);
BEGIN
-- Exist the table ?
SELECT OBJECT_NAME INTO table_to_fill FROM USER_OBJECTS
WHERE OBJECT_NAME = UPPER(origin_table) AND OBJECT_TYPE = 'TABLE' ;
IF wCondition IS NULL THEN
where_clause := NULL;
END IF ;
EXECUTE IMMEDIATE 'INSERT INTO ' || table_to_fill || ' SELECT ' || list_of_fields || ' FROM ' || origin_table || where_clause ;
EXCEPTION
WHEN NO_DATA_FOUND THEN
-- Here the Alert
END;
But, when I compile this error is displayed:
Function not supported from client side application corresponding to SQL statement EXECUTE IMMEDIATE
How can to correct this script for my form ?
I hope in Your help.
Best Regards
GaetanoYou have two options:
1)To create this procedure in database
2)Yo use the forms built-in FORMS_DDL instead of execute immediate , altering the one provided

How can i pass multiple values by a single variable to EXECUTE IMMEDIATE
Hi All,
I want to pass multiple values for where condition for execute immediate. Something Like this:-
bold
Declare
v_cond varchar(1000);
Begin
v_cond := '''INR','USD'''; --(OPTION 1)
v_cond := 'INR,USD'; --(OPTION 2)
EXECUTE IMMEDIATE 'Delete from table where colm in (:v_cond)' using v_cond;
END;
bold
I am using this into a procedure
Now option 1 gives an error ie a syntax error (; expected or something like that)(I am sorry, i can't tell the exact error here as i am not in the office right now)
and option 2 makes the procedure execute but obviously doesn't delete the records, as it takes the whole as one.
Please Help

How to set multiple parameters in one EXECUTE IMMEDIATE sql
I want to set both nls_language and nls_date_language, and set them as different languages. fnd_global.set_nls_context() doesn't work.

So you can also manually put the code in a BEGIN..END block and run like this.

Why this code is not of your interest, something like this

execute immediate 'alter session set nls_language = ''AMERICAN''';

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).

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:

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;
END;
