return true;
END;
this is the procedure i have used. it works fine in server side but not in client side. pls help me to solve this problem.
Advance tanx

The reason your process won't compile is that you are using a package variable, dbms_sql.v7. (Why aren't you using dbms_sql.native?) If you change that variable to a value of 1 it will probably work.
However, Francois is correct -- In Forms, you should be using the Exec_SQL package. It is built for Forms; Oracle does not support using DBMS_SQL from Forms. In fact, if you use Forms Builder 10g connected to Oracle 9i and try to compile, the compiler fails with internal errors. They say it works again if you connect to Oracle 10.
Exec_SQL is identical to DBMS_SQL, except for exception handling. You have to make an additional call to catch the error if an exception occurs: Exec_SQL.Last_Error_Code

How can I execute Dynamic SQL statement in Forms?

Hi All,
I have to execute dynamic SQL statement from Forms
Below statement I have to execute
"EXECUTE IMMEDIATE v_stmt INTO v_return;".
Googled for the same got results saying, Better use Database function or procedures to execute these Dynamic Statements but We want to execute in forms only.
Can any one help me..
Thanks,
Madhu

So in short you are trading code obfuscation for maintainability and the ability to share code between tools? If from somewhere else you need a procedure already implemented in database PL/SQL (and now ported to forms) this would mean you'd need to implement it in every other tool. In times where you might want to integrate your forms with $other_technology and putting stuff on the database is the first step to share functionality you just go the opposite way? And all that because someone is afraid that somebody might steal your source code? I am sorry to be blunt, but this is just plain stupid.
Leaving aside that some things like Analytic Functions, Bulk processing or execute immediate are not even available in forms your software consists of how many LOC? How long does it take to bring a new developer up to speed with your source code? Imagine how long that would take for a developer who doesn't have coleagues who know their way around.
And just so you know: I work for a ISV selling a closed-source product as well. We have 200+ customers all over the planet. We are well aware that wrapped packages can be reverse engineered. The premise is: stored procedures can be reused in every tool we have, if it makes sense to put stuff on the database by all means do it. If someone would want to reverse engineer our software I'd wish him good luck as some parts are implemented in such a hilarious complicated way I have troubles understanding them (and quite frankly I refuse to understand certain parts, but that's another story). I do work for almost 10 years for that ISV.
In any case the possible solutions have already been mentioned: you have exec_sql, create_group_from_query and forms_ddl to execute dynamic SQL in forms whereas forms_ddl is a one way street and most certainly not the thing you need or want. Take a look at the documentation for the other 2 things.

How to Use Dynamic SQL

Can anybody please send me a small program on How to Use Dynamic SQL.
How to execute and run give details.
Thanks

You can certainly use the INTO (and USING) clauses of EXECUTE IMMEDIATE to pass in and return data, i.e.
EXECUTE IMMEDIATE sqlStmt
USING variable1, variable2
INTO output1, output2The more complex the statement, however, the more appropriate DBMS_SQL is. DBMS_SQL also has the potential to allow you to use bind variables rather than reparsing the statement many times.

How to execute an SQL query present in a string inside an ABAP program?

hello,
How to execute an SQL query present in a string inside an ABAP program

Raut,
You can execute Native SQl statements.
Ex: To use a Native SQL statement, you must precede it with the EXEC SQL statement, and follow it with the ENDEXEC statement as follows:
EXEC SQL [PERFORMING <form>].
<Native SQL statement>
ENDEXEC.
There is no period after Native SQL statements. Furthermore, using inverted commas (") or an asterisk (*) at the beginning of a line in a native SQL statement does not introduce a comment as it would in normal ABAP syntax. You need to know whether table and field names are case-sensitive in your chosen database.
In Native SQL statements, the data is transported between the database table and the ABAP program using host variables. These are declared in the ABAP program, and preceded in the Native SQL statement by a colon (:). You can use elementary structures as host variables. Exceptionally, structures in an INTO clause are treated as though all of their fields were listed individually.
If the selection in a Native SQL SELECT statement is a table, you can pass it to ABAP line by line using the PERFORMING addition. The program calls a subroutine <form> for each line read. You can process the data further within the subroutine.
As in Open SQL, after the ENDEXEC statement, SY-DBCNT contains the number of lines processed. In nearly all cases, SY-SUBRC contains the value 0 after the ENDEXEC statement. Cursor operations form an exception: After FETCH, SY-SUBRC is 4 if no more records could be read. This also applies when you read a result set using EXEC SQL PERFORMING.
EXEC SQL PERFORMING loop_output.
SELECT connid, cityfrom, cityto
INTO :wa
FROM spfli
WHERE carrid = :c1
ENDEXEC.
Pls. Mark If useful

How to execute dynamic if statement...

Hi All,
My PL/SQL Blocks looks like this
declare
i_string :='if 3>20 then 1 else 2 end if;' varchar2(100);
begin
end;
Between begin and end i want a piece of code which executes that if statement and sends 2 as output in dbms_output.put_line since 3 is not >20 .Basically i want to know how to execute dynamic if statement.Please help
Thanks,
Preethi

Hi,
i agree with Cyn. Dynamic SQL is often a bad idea. Try to avoid it.
Dynamic PL/SQL is even worse. If you really must do something dynamic, at least try to cast it as SQL rather than PL/SQL.
Does this do what you want?
CREATE OR REPLACE FUNCTION     eval_case
(     in_txt     IN     VARCHAR2
RETURN     NUMBER
DETERMINISTIC
IS
     return_val     NUMBER;
     sql_txt          VARCHAR2 (1000);
BEGIN
     sql_txt := 'SELECT CASE '
          ||           in_txt
          || '         END'
          || ' FROM dual';
     EXECUTE IMMEDIATE sql_txt INTO return_val;
     RETURN     return_val;
END     eval_case;
SHOW ERRORSYou might use the function above like this:
declare
     i_string varchar2(100) :='WHEN 3>20 THEN 1 ELSE 2';
begin
     dbms_output.put_line ( TO_CHAR (eval_case (i_string))
                    || ' = results of eval_case ('''
                    || i_string
                    || ''')'

How to execute a .sql file from a batch file

Hi all
I've to take backup of a database weekly twice on every wednesday & Friday @ 5pm IST. I've written a hot backup script, which works every well.
now i want to automate the script. ie i want this script to run on wednesday & friday @ 5pm without any human interfearance ie with out actually any1 executing this script.
i created a batch file prod.bak with the following lines
@echo off
set oracle_sid=testdb
set oracle_home=d:\oracle\ora92
sqlplus /nolog
connect sys as sysdba/oracletest@testdb
this batch file when eexecuted connects me to sql prompt.
Now i want to execute my backup script bkp.sql automatically when it is connected to sql prompt.
(i tried with these lines in the above batch file...
call bkp.sql---it just opens the bkp.sql file in notepad & displays the script
start bkp.sql---same as call
connect / as sysdba/pwd@[email protected] --- does not work simply remains a the sql prompt.
At 17:00 /Every:w,f "d:\bkp.sql"---does not work simply remains at the sql promt.)
Can any1 let me know what should i write in the batch file that will execute the bkp.sql file automatically after it gets connected to sql prompt. M using oracle 9i.
I'll manage he time through windows utility of scheduling task.. Let me know how to execute the .sql file from a batch file.
Thanks
Tripti

Try
sqlplus "sys/oracletest as sysdba" @bpk.sql
Working locally, and having set the ORACLE_SID, you don't need to specify the SqlNet alias (@testdb).
Remember to put an exit at the end of the bpk.sql script.

Doesn't work. Even though @ is different from start in this case but it just doesn't like the way sql and plsql are mixed. For example:
DECLARE n NUMBER := 0;
BEGIN
select COUNT(*) INTO n from user_tab_partitions;
DBMS_OUTPUT.put_line('Number of partitioned tables = ' || to_char(n));
if n = 0 then
DBMS_OUTPUT.put_line('createViewsProcs.sql');
@createViewsProcs.sql
else
DBMS_OUTPUT.put_line('createPartitionViewsProcs.sql');
@createPartitionViewsProcs.sql
end of;
END;
SQL> @postimp.sql
SQL> DECLARE n NUMBER := 0;
2 BEGIN
3 select COUNT(*) INTO n from user_tab_partitions;
4
5 DBMS_OUTPUT.put_line('Number of partitioned tables = ' || to_char(n));

7 if n = 0 then
8 DBMS_OUTPUT.put_line('createViewsProcs.sql');

Execute Dynamic SQL statement using procedure builder

i want to execute a dynamic SQL statment using procedure builder not using forms
because my statement depending on a variable table name
i know that i can do that from forms using
FORMS_DDL('SQL_STAT');
but i wanna to use the procedure builder
which function i should use and how?
please explain in example if you don't mind.

Hi,
You can very well use DBMS_SQL Package supplied by Oracle for doing this.
Search for DBMS_SQL in OTN. You will get all info regarding this.

How to use dynamic SQL in this case for best performance

I have the table with following columns
ID NUMBER,
DATA LONG,
TAG VARCHAR2(255)
Records in this table will be like following
1 this is an abstract ABSTRACT
1 this is author AUTHOR
1 100 PRICE
2 this is an abstract ABSTRACT
2 this is author AUTHOR
3 contract is this CONTRACT
Basically all the records with the same number constitute 1 record for another table. Tag in the above table indicates that what column it is and DATAwill have the actual data for that column. I need to populate the second table based an the above table but will not get the same number of TAGS all the time. I need to insert the values only for the columns provided in the TAG field. How will I accomplish this by dynamic sql. Do I create a loop and create two strings one with columns and one with values and then combine them and use execute immediate to insert into table? Is there an easier way to do this??
Please respond quickly.
Thanks
Bhawna

> so which collection should i use to perform it..
so that performance is best......
Program to interfaces. That way, you can switch out implementations and test for yourself which performance is best in an actual production context. But first, write your program so that it works. Worry about refactoring for performance once your program is written and it works.
