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 can I write a SQL statement which checks if a table exists?

How can I write a SQL statement which tells me whether a table exists?

execute an sql query: select * from <tablename>
catch the exception n check whether the erroe code
matches the one that occurs for table doesn't exist
that's itHow is your answer any different from the one given in the first reply?
It isn't.
As WorkForFood says DatabaseMetaData has a bunch of methods for getting information about tables but this is more useful when you don't know the names of any of the tables.. it sounds like you do so I would concur SELECT from table is probably the quickest way to go. If it helps the Xopen error should be either S1000 or 42S01 (I think) but I would try and see if there is a specific vendor code for table not found/not exists error and check for that.

How can i use one SQL statement to solve problem?

How can i use one SQL statement to solve the question below?
For a Table named A, there is a column named F(char type).
Now select all the records where F like '%00' and update their F value to '%01'
Just one SQL statement.Do not use PL/SQL block.
How to do that?
Thanks.

What is the data volume for this table?
Do you expect lots of rows to have '%00' as their value?
Following two statements come to mind. Other experts would be able to provide better alternatives:
If you have index on SUBSTR(f, 2):
UPDATE A
SET    f = SUBSTR(f,
                  1,
                  length(f) - 2) || '01'
WHERE substr(f,
              -2) = '00';If most of the rows have pattern '%00':
UPDATE A
SET    f = SUBSTR(f,
                  1,
                  length(f) - 2) ||
           DECODE(SUBSTR(f,
                         -2),
                  '00',
                  '01',
                  SUBSTR(f,
                         -2));

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.
thanks

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 execute multiple SQL statements thru frontend?

With SQL Server database, you can execute multiple SQL statements.
Ex.
SQLCommand cmd = new SQLCommand();
cmd.CommandText = "SELECT * FROM EMP; SELECT * FROM DEPT";
cmd.ExecuteXXX();
Note that for SQL Server, ";" (semocolon) is used as a separator.
What separator is required for Oracle ? Or rather, can I execute multiple SQL statements against Oracle database (10g) ?
(Why I want to do it is a totally diff. subject !)
Thanks,
Ami.

Hello,
You could use an anonymous PL/SQL block to batch multiple statements.
If you want to use SELECT statements, you would open a REF CURSOR for each SELECT and return the REF CURSOR to your application. INSERT, UPDATE, and DELETE statements can just be passed as is.
A simple REF CURSOR example might look like:
begin
open :v_refcursor1 for select * from emp;
open :v_refcursor2 for select * from dept;
end;Where v_refcursor1 and v_refcursor2 are parameters defined as a REF CURSOR type.
Hope that helps a bit...

Need help on Dynamic SQL Cursor in Forms

Hi All,
I am trying to execute Dynamic SQL Cursor in forms using EXEC_SQL built in.
I have a cursor for example:
'select * from supplier where supplier = '||p_supplier||' and processing_order = '||p_order
My code is
cur_num := Exec_SQL.Open_cursor;
sql_order := 'select * from supplier where supplier = '||p_supplier||' and processing_order = '||p_order;
EXEC_SQL.PARSE(cursor_number, sql_order);
EXEC_SQL.DEFINE_COLUMN(cur_num ,1,ln_Supp_Id);
EXEC_SQL.DEFINE_COLUMN(cur_num ,2,ls_Suppl_Name,30);
EXEC_SQL.DEFINE_COLUMN(cur_num ,24,ls_exchange,20);
sql_count := EXEC_SQL.EXECUTE(cur_num );
While EXEC_SQL.FETCH_ROWS(cur_num ) > 0 Loop
        EXEC_SQL.COLUMN_VALUE(cur_num ,1,ln_Supp_Id);
        EXEC_SQL.COLUMN_VALUE(cur_num ,2,ls_Suppl_Name);
        EXEC_SQL.COLUMN_VALUE(cur_num ,24,ls_exchange);
End Loop;
EXEC_SQL.CLOSE_CURSOR(cur_num );
In this case I have to write 24 Define Columns and 24 Column value. Is there any way to assign them to %rowtype at one time as I need all coulmn of the table.
I had similar case on multiple tables.
Please help me
Thanks,
Maddy

I need this dynamic sql because p_supplier and p_order values changes at run time
I do not understand. Is this a simplified sample or the real thing? You do know that you can pass variables to cursors:
cursor test is
select * from supplier where supplier = p_supplier and processing_order = p_order;
or does e.g. p_supplier hold other parts of the query?

How can I open a cursor for dynamic sql statement

Hi,
I'm facing issues opening a cursor for dynamic sql statement : PLS-00455: cursor 'RESULT1' cannot be used in dynamic SQL OPEN statement.
CREATE OR REPLACE FUNCTION DEMO
(MN_I in VARCHAR)
return AB_OWNER.ABC_Type.NonCurTyp is
RESULT1 AB_OWNER.ABC_Type.NonCurTyp;
sql_stmt VARCHAR2(4000);
BEGIN
sql_stmt := 'SELECT * FROM AB_OWNER.DUN WHERE JZ_I in ('||mn_i||') ORDER BY app.ACC_I';
OPEN RESULT1 FOR sql_stmt;
END IF;
return RESULT1;
END DEMO;
What changes should I make in the code so that it doesn't fail? I can't change the definition of RESULT1 cursor though.

And you will have to regularly restart the server, or possibly slightly less invasive, flush the shared pool.

You are not using bind variables. This is terrible. Flushing the shared pool is a bad
solution -- you are literally killing the performance on your box by not using them.
If I was to write a book on how to build non scalable applications in Oracle, this
would be the first and last chapter. This is a major cause of performance issues and a
major inhibitor of scalability in Oracle. The way the Oracle shared pool (a very
important shared memory data structure) operates is predicated on developers using bind
variables. If you want to make Oracle run slowly, even grind to a total halt just
refuse to use them.

How can I execute Stored Procedures in PARALLEL and DYNAMICALLY ?

Hi
I have a stored procedure. It can be executed like this
exec test @p = 1;
exec test @p = 2
exec test @p = n;
n can be hundred.
I want the sp being executed in parallel, not sequence. It means the 3 examples above can be run at the same time.
If I know the number in advance, say 3, I can create 3 different Execution SQL Tasks. They can be run in parallel.
However, the n is not static. It is coming from a table.
How can I execute Stored Procedures in PARALLEL and DYNAMICALLY ?
I think about using script task. In the script, I get the value of n, and the list of p, from the table, then running a loop with. In the loop, I create a threat and in the threat, I execute the sp like : exec test @p = p. So the exec test may
be run parallel. But I am not sure if it works.
Any idea is really appreciated.

Hi nam_man,
According to your description, you want to call stored procedures in parallel, right?
In SSIS, we can create separate jobs with different stored procedures, then set the same schedule to kick the jobs off at the same time. In this way, we should be careful to monitor blocking and deadlocking depending on what the jobs are doing.
We can also put all stored procedures in SSIS Sequence container, then they will be run in parallel.
For more information about SSIS job and Sequence container, please refer to the following documents:

https://msdn.microsoft.com/en-us/library/ms139855(v=sql.110).aspx
If you have any more questions, please feel free to ask.

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
                    || ''')'
end;

How can I execute a Procedure with OUT variable is %ROWTYPE on SQL Prompt

Hi,
I have a procedure with OUT variable is %ROWTYPE
How can I execute the following procedure on SQL prompt.
(without creating anonymous block)
CREATE OR REPLACE PROCEDURE zz_sp_EMP(VEMPNO IN EMP.EMPNO%TYPE,
V_REC IN OUT EMP%ROWTYPE)
AS
BEGIN
SELECT * INTO V_REC FROM EMP WHERE EMPNO = VEMPNO;
END;
Thanks & Regards,
Naresh

as previous posters said: it's not possible to do this without declaring a variable in the anonymous block.
With anonymous block it would look like this (had to change it a bit, since i'm using hr-schema on oracle XE):
declare
l_rec EMPLOYEES%ROWTYPE;
begin
zz_sp_EMP(VEMPNO => 100, V_REC => l_rec);
DBMS_OUTPUT.PUT_LINE ( 'first_name = ' || l_rec.first_name );
DBMS_OUTPUT.PUT_LINE ( 'last_name = ' || l_rec.last_name );
end;
first_name = Steven
last_name = King

How can I execute a statement before a VO is running

JDEVADF_11.1.1.3.PS2_GENERIC_100408.2356.5660
I use ADF BC
how can I execute a statement before a VO is running

thanks for the answer
i use a logon function before I run a VO
after a certain time will be disconnected
and I have to call the function again
sorry for my English
public String logon(String username, String password){
CallableStatement st = null;
this.username = username;
this.password = password;
try {
st = getDBTransaction().createCallableStatement("begin ep_security.LogOn(?,?); end;",0);
st.setObject(1, username);
st.setObject(2, password);
st.executeUpdate();
this.getDBTransaction().commit();
} catch (SQLException e) {
System.out.println("ERROR "+e.getMessage());
this.addWarning(new JboWarning("Quote retrieved successfully"));
System.out.println("...RETURN ERROR");
return "error";
} finally {
if (st != null) {
try {
// 7. Close the statement
st.close();
} catch (SQLException e) {
e.printStackTrace();
}

Preparing Dynamic SQL statement for inserting in Pro*C

Hi Friends,
From quite some time i am struggling writing Dynamic SQL statement for dynamic insert and update in Pro*C.
Can somebody go through my code and suggest me the rigth way of doing.
Right now it throws an error saying " Error while updating ORA-00904: invalid column name "
Please help me.
Girish.
int main()
EXEC SQL BEGIN DECLARE SECTION;
char *uid ="scott/tiger";
static char sqlstmt[129];
struct /* DEPT record */
int dept_num;
char dept_name[15];
char location[14];
} dept_rec;
EXEC SQL END DECLARE SECTION;
EXEC SQL WHENEVER SQLERROR DO sql_error();
EXEC SQL CONNECT :uid;
dept_rec.dept_num = 50;
strcpy(dept_rec.dept_name,"ADMIN");
strcpy(dept_rec.location,"IN");
strcpy(sqlstmt,"UPDATE dept set DNAME = dept_rec.dept_name where DEPTNO = dept_rec.dept_num");
EXEC SQL EXECUTE IMMEDIATE:sqlstmt;
EXEC SQL COMMIT;
exit(0);
void sql_error()
printf("\nError while updating %s",sqlca.sqlerrm.sqlerrmc);
EXEC SQL ROLLBACK;
}

A bit rusty here but this is how I see it.
Think of it this way ..
all Oracle is going to see is:
UPDATE dept set DNAME = dept_rec.dept_name where DEPTNO = dept_rec.dept_num
Its NOT going to know what dept_rec.dept_name is or dept_rec.dept_num is ..
it doesnt go back and fill in those values.
You need something like
strcpy(sqlstmt,"UPDATE dept set DNAME = \"");
strcat(sqlstmt,dept_rec.dept_name);
strcat(sqlstmt,"\" where DEPTNO = ");
strcat(sqlstmt,dept_rec.dept_num);
printf(sqlsmt); # Just to be sure the update statement look right during testing.
