Using Dynamic SQL in Forms

Does anyone know anything about Dynamic SQL not being available in Forms v. 6.0.8.11.3? I trying to use Dynamic SQL for the first time and am having some difficulty. When I try to put my SQL in a function and run it straight into the database through SQLPlus, it works fine, but when trying to compile the code in Forms Builder (in a library), I get compiler errors. Any help would be appreciated...
Thanks!
Vanessa

When I tried to compile the following code in Forms, the compiler error I got was Encountered the symbol "STMT_STR" when expecting one of the following: select. However, when I run it in SQLPlus, it creates the function without any errors.
FUNCTION my_func
return number
is
TYPE DiaryCurTyp IS REF CURSOR;
cur DiaryCurTyp;
stmt_str VARCHAR2(200);
dmonth NUMBER;
dday NUMBER;
BEGIN
stmt_str := 'SELECT dmonth, dday FROM p2_diary
WHERE dmonth = :1';
OPEN cur FOR stmt_str USING '12';
LOOP
FETCH cur INTO dmonth, dday;
EXIT WHEN cur%NOTFOUND;
-- <process data>
END LOOP;
CLOSE cur;
END;

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
null

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.

PL/SQL procedure successfully completed.

PL/SQL code runs on the server, inside an Oracle process - thus PL/SQL code cannot dynamically write and display messages to the client. That server process is not connected to any keyboard, mouse or display.
DBMS_OUTPUT can be used. This is a PL/SQL buffer area in that server process that code can write lines of text too. When the server process informs the client that it has completed, the client can now request the contents of the DBMS_OUTPUT buffer and the client can display it on the client device.
This is what set serveroutput on in SQL*Plus does - tell the sqlplus client to request the DBMS_OUTPUT buffer after each Oracle server call made and to display the contents locally.
So to display the SQL command can be done using DBMS_OUTPUT. E.g.
declare
dropPart varchar2(32767);
begin
for c in (select...) loop
    dropPart := 'alter table my_tab drop partition '||c.partition_name';
    --// write the SQL command to DBMS_OUTPUT
    DBMS_OUTPUT.put_line( dropPart );
    --// execute the SQL using a begin..end block in order to catch error
    begin
      execute immediate dropPart;
      DBMS_OUTPUT.put_line( 'command completed successfully' );
    exception when OTHERS then
      DBMS_OUTPUT.put_line( 'command failed with: '||SQLERRM(SQLCODE) );
    end;
end loop;
end;So after this code block has been executed and partitions dropped, sqlplus will display the DBMS_OUTPUT generated by this code block.

Delcare Cursor using Dynamic SQL using PL/SQL in Oracle 7.3.4

In Oracle 7.3.4, can I declare a cursor at run time using Dynamic SQL. From the sample code in this website, it seems that Oracle 8 support this function. Please help. Thanks a lot.
If I can do this on Oracle 7.3.4, could you give me some sample codes? Thanks.
Regards,
Raymond

Hi,
Try using the the following code where you can dynamically build the Valid Select stmt. and call that where ever you want.
declare
Type Cur_ref Is Ref Cursor;
C_ref Cur_ref;
V_Str Varchar2(100);
V_Name Varchar2(100);
Begin
V_Str := 'Select Ename from Scott.emp Where empno = 7369';
Open C_Ref for V_Str;
Fetch C_ref Into V_Name;
close C_Ref;
dbms_output.put_line(V_Name);
End;

Using pl/sql in forms to access rs232 information

Does anyone know how to capture information receved from serial port (example: serial code) using pl/sql with forms.
THX.

What you need is a 3rd party comm ocx or ole
control like SAXCOMM,PDQCOMM etc.
Once this is loaded on your machine , then using forms goto the programs "import OLE libray interfaces" option and load the commms control you are using. You must choose the events and methods. Once this is done then the programme units should be updated with the procs (methods) you can call.
I hope this helps.

Using dynamic sql in triggers with :OLD values

i need to record all deleted rows from an entire schema in a single table. for that matter i created a function that receives a table name and generate an insert command according to it's primary key columns. i call this function in the table triggers. in order to insert the old values before the delete i use :OLD with "execute immediate" as followed :
create or replace trigger trg_some_tbl_bd
before delete on some_tbl
for each row is
declare
v_sql varchar2(4000);
begin
v_sql := generate_insert_command('some_table');
execute immediate v_sql;
end;
the return value from "generate_insert_command" function is the string:
insert into deleted_table (table_name , date , pk1 , pk2) values
('some_table' , sysdate , :OLD.pk1 , :OLD.pk2)
the execute immediate command notice the :OLD and looks for bind variables.
i need to know i can i bypass that. i tried looking for escape characters but couldent find any...
i would appriciate any help , it's kynda urgent
Thanks !

I don't believe this is going to work. Even if you could get around the fact that :old looks like a bind variable, the :old values are not visible to the dynamic SQL statement, they're like local variables in that respect.
If you wanted to pass old values in, those values would have to be passed in as bind variables, i.e.
EXECUTE IMMEDIATE v_sql USING :old.pk1, :old.pk2which defeats the purpose of using dynamic SQL.
Since you have to create a trigger for each table, I don't see why you would bother with dynamic SQL inside the trigger-- your table structure is fixed when the trigger is created. You could write dynamic SQL that generated the triggers in the first place, but the code inside the trigger should be dynamic.
As an aside, you realize that logging every audit record into a single table creates rather massive contention issues, right? And have you considered how painful it is to query this sort of table? Have you considered other options for maintaining history like Workspace Manager? Or at least separate history tables for each table?

Hello,
>
I'm trying to create a function utilizing Dynamic SQL. But why?
Whenever you turn towards dynamic SQL, ask yourself why?
I bet for a couple of years you aren't able rto come up with an answer. Meaning you shouldn't.
Even if you do come up with an answer, think again. The answer may very well be wrong.
Wouldn't it be nice if your function was as simple as:
CREATE OR REPLACE FUNCTION prod_sales_data
   ( p_ahl1      IN VARCHAR2
   , p_phl1      IN VARCHAR2
   , p_fisyr     IN NUMBER,
     p_prod_str IN VARCHAR2)
RETURN NUMBER
IS
   v_return NUMBER;
BEGIN
    select sum(a.qsh*a.unitcnt)
      into v_return
      from sh_units a
         , sh_product_desc b
         , sh_ad_glass c
     where a.unittype = b.unittype
       and a.sh_id = c.sh_id(+)
       and a.ahl1 = p_ahl1
       and a.phl1 = p_phl1
       and a.fisyr = p_fisyr
       and upper(b.descrip) = upper(p_prod_str)
       and a.invdt between b.eff_beg and b.eff_end
       and a.parts_flag != 'Y'
       and a.unittype != 'OTHE'
       and icim.sh_rept_chk_ortp(a.ortp) = 1
       and a.rept_release_dt is not null;
RETURN v_return;
EXCEPTION
   WHEN NO_DATA_FOUND THEN
      RETURN NULL;
END prod_sales_data ;
/Now using proper bind variables, plain static pre-compiled SQL. And even works properly WITH NO DATA FOUND.
I know it's dangerous to use words as always and never, but i dare say
Always (Whenever you can) use static SQL. Never (Unless you must) use dynamic SQL (When you can use static).

Should I use dynamic SQL for simple updates?

Please tell me, out of the two options given below, which option should i use to update columns in a table and why?
what will be the performance difference between the two approaches?
Please note: The options given below is just for an example
procedure proc1(var1 varchar2)
is
begin
update tab1 set col1 = var1;
commit;
end;
procedure proc1(var1 varchar2)
is
sqlstr varchar2(1000);
begin
sqlstr := 'update tab1 set col1 = :v1';
execute immediate sqlstr using var1;
commit;
end;
Thanks
Arun

Arun G Nath wrote:.

Performance is not the issue (as long as you are using bind variables).
But with dynamic SQL, you loose compile time checking; you do not know until runtime if the SQL is valid.
You also loose the dependency between proc1 and tab1, which can be found only if you search user_source.
(And in either case, you probably want to remove the commit)

Using database link with a dynamic SQL in Forms 5

I have a Form 5 application where a database link is specified in a client version of dynamic SQL. The function that the application is designed to perform is to access data in a table in a remote database and use it to populate another table in a local database with the same structure as the source table. Dynamic SQL is used because the name of the table can only be resolved during run time.
The problem is that it gives error with code 'ORA-03113' and text 'End-of-file on communication channel' when you try to run it.
Is it not possible to use a database link with a dynamic SQL? What can I do to overcome the problem ?

Try to create a local view based ao the remote table and use the view.

Using Native Dynamic SQL in Forms

Can Native Dynamic SQL be used in Forms 5.0 or Forms 6.0? (Database 8.1.6.0.0)
I have tried the following code (examples below) from the PL/SQL User's Guide and Reference Release 8.1.6 and the Metalinks Note: 62592.1 and the trigger/procedure (in Forms) will not compile. I appreciate any help given.

Using Dynamic LOV in Forms

Hi Everybody,
I am making forms based on procedures in 9iAS Portal. I am using two parameters for the form. One is Item Code for which I am having a simple LOV with sql statement. Other LOV has a dynamic Sql statement which accepts the Item_code as parameter and displays records containing the item_code. When I run the Lov seperately through navigaror it runs properly but when I used the lov through form and passed the item_code to it, on runtime it says that the lov is based on dynamic sql and unable to show results.
Can anybody please help me out of this problem.
Thanks in advance

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

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.
