Dynamically call another procedure

In SQLServer you can have a variable that holds a procedure
name. The variable can then be used in the execute statement.
Is there any way in PLSQL to dynamicaly call another procedure.
example:
begin
declare procname varchar2(32) = 'proc1';
--now call the procedure
procname -- ?
execute immediate procname -- ?
end;
Thanks,
Dermot.

Just wrap it in an anonymous block:
create or replace procwrap
(p_procname in varchar2)
is
begin
execute immediate 'begin ' || p_procname || '; end;';
end;

In SQLScript, how to use EXEC to call another procedure with parameters in procedure?

Hi experts,
In SQLScript, How to use EXEC to call another procedure with input and output parameters in procedure？thanks very much

Hi Sagar,
thank you! I generate another procedure with an input parameter and an output parameter in a procedure. Then i need to call the generated procedure using EXEC. Here is my code:
create procedure ftest1(out sum_num bigint)
as
begin
declare fa_output bigint;
declare v_sql_drop varchar(200);
declare v_sql varchar(500);
declare cursor c_cursor1 for select num from TABLE1;
--v_sql_drop := 'drop procedure fe';
--exec v_sql_drop;
v_sql := 'create procedure fe(in i_num bigint,out o_num bigint) as begin';
v_sql := :v_sql || ' o_num := :i_num * 2 + :i_num * :i_num;';
v_sql := :v_sql || ' end';
exec v_sql;
open c_cursor1;
for c_item as c_cursor1 do
exec 'call fe(c_item.num,o_num=>fa_output)';
if sum_num is null then
sum_num := fa_output;
else
sum_num := :sum_num + fa_output;
end if;
end for;
close c_cursor1;
end;
The underline code is using exec to call the generated procedure. But this method cannot work. Any suggestion? thanks again!

Writing a simple procedure to call another procedure

Greetings,
im pretty new to pl/sql and just recently started playing around with it, I was wondering howi would go about creating a basic skeleton of procedure that would call another procedure.
function testfunction is the function I wish to call and accepts 3 params, it then returns a pl/sql table which contains all the rows I want. I then want to populate a table with this data. Do I need to create a loop within the procedure to populate the table or can I use a function of some sort to just directly insert the entire pl/sql table into the actual table?

Thankyou both for the follow ups! I may have to go with the loop method but before I dive into that I was reading about the merge function and feel as though it would do what I need perfectly (I just need to append data to a table)
So I came up with something like this
PROCEDURE test_procedure
IS
BEGIN
MERGE INTO test_table
USING (test_package.test_function(123, 456, 789))
WHEN MATCHED THEN UPDATE SET FIELDA = resulta, FIELDB = resultb, FIELDC = resultc
WHEN NOT MATCHED THEN INSERT (FIELDA, FIELDB, FIELDC) VALUES (resulta, resultb, resultc)
END test_procedure;
This seems like it would work great, the resulta, resultb, and resultc are all returned from the function but im not sure exactally about that being the correct way to call it. I will go read up on this approach but fall back on the looping if it doesnt work out, thankyou everyone =D

Need to write a plsql block for calling another procedure.

Hi Guys,
I have a requirement to write a plsql block and to call another procedure which is having 5 parameters (each parameter having multiple values). Calling procedure generates one SQL query and it needs to be generated all combinations and print in another table.
I need to pass multiple values for first three parameters from my PLSQL block and run.
call sample proc:
procedure(
param1 varchar2,
param2 p_varchar2,
param3 p_varchar2,
param4 in varchar2,
param5 in number
is
begin
ls_sql_query := 'with client_query as (select * from table)';
end;
Thanks in advance!

This article is on exactly your subject. It is worth a careful read.
Ask Tom: On Popularity and Natural Selection
I paraphrase: "Always code a reference to every possible bind variable but do so in such a way that the optimizer removes the bind variable for us if we aren't going to actually use it in that particular execution of the SQL statement."
P.S. This is the same answer I gave when you asked the same question earlier.

Pocedure calling another procedure

Hi all,
I hav a procedure which will display all the student records.
CREATE OR REPLACE procedure a

1) I want to use this procedure inside another procedure say b to display only certain cousre records. How can i do that?
2) I want to use this procedure inside another procedure to display particular student's different course grades. How can i do that?

PL/SQL is not usually used this way - displaying data. The DBMS_OUTPUT interface is very primitive - and does not "display" anything. It is a static PL buffer that contains lines. The client, e.g. SQL*Plus/TOAD, displays its contents after calling Oracle to execute code.
That said, PL/SQL can be used to teach programming fundamentals - despite the fact that this is NOT how one would usually apply the PL/SQL language to real problems.
A display procedure should be just that - display. Nothing else. A well designed procedure (or function) does a single job, and does it well. So a display proc can look as follows:
create or replace procedure DisplayStudent( studentRow lgrage%rowtype ) is
begin
dbms.output.put_line( ... insert your display contents ... );
.. etc ..
end;
1) I want to use this procedure inside another procedure say b to display only certain cousre records. How can i do that?
2) I want to use this procedure inside another procedure to display particular student's different course grades. How can i do that?The same way. By using SQL to specify the data set that you want to display. For example:
begin
for student in ( select l.* from lgrade l where l.score >= 80 ) -- display students with a score of 80% plus
loop
DisplayStudent( student ); -- call the display proc and pass it a student row to display
end loop;
end;
/And that is the basic approach. Two important factors.
Modularise. A good program design means creating building blocks to solve the problem. Where a block can be re-used (like the DisplayStudent procedure above).
Maximize SQL. SQL is a very capable and powerful program language. You use it to crunch the data. You do not pull all the rows from the table into PL/SQL and then apply an IF condition to filter the data. That is row-by-row and slow-by-slow processing.

Calling another procedure in a procedure

PL/SQL precedure calling another procedure

Can someone provide an example of a procedure calling a second procedure. I have two procedures which work fine when called via exec from sql*plus, but when the first trys to call the second, I start getting errors. The first execute immediate runs, but errors out, the second execute immediate doesn't compile.
Thanks
HeaderProc

ChildProc
(p_key IN number) is
cursor h is

for current_child in h
loop
dbms_output.put_line('"' | | current_child.cval1 | | '","' | | current_child.cval2 | | '"');

To call a proc from another proc simply call it by name from the first proc.
childproc(current_header.key) ;
null

How to call another procedure???

I create a procedure, and inside this procedure there are others procedures in xxx.sql (vi file)...
how to call these procedutes???
Urgent...
Thanks

If I understood well u have two sql files, say x.sql and y.sql (u used vi to write them).
Suppose u want to call y.sql in a certain row of the x.sql file. Then just put inside the x.sql file.
@y
If you have a PL/sql procedure inside your sql file, maybe it's different.
I hav't tried all of the possibilities, but if the procedure u want to call is a stored one, just call its name.
I hope it helps.
Bye Dino

Dynamic SQL Stored Procedure call in Pro*C Application

Hello All
Could you help with a sample Pro*C program (or snippet) which has a dynamic call to a stored procedure? The procedure to be called is determined at run time and so also the number of parameters to it.
Is this even possible using Pro*C?

Update Query with Results From another Procedure

I am not sure if you can do this or what the proper format of the command might look like.
I have a stored procedure which insert records into a database. I want to insert the records which are returned by calling another procedure. This other procedure returns a cursor object to a variable named o_rows. Can this be done using Oracle 8i?
Insert into MyTable
MyStoredProcedure(oRows);

You have a couple of options.
1) You can turn your stored procedure into a pipelined table function. This would allow you to do something like
INSERT INTO myTable
SELECT *
FROM TABLE( myStoredProcedure() );I don't believe that pipelined table functions were available in 8i, however.
2) The other option would be to fetch rows from the cursor and insert those into your table. Something like
LOOP
FETCH oRows INTO col1, col2, col3, col4, ...
INSERT INTO myTable( <<column list>> )
VALUES( col1, col2, col3, col4 );Note that for simplicity I am omitting the declarations of the local variables col1, col2, etc. and the check to see whether the cursor was exhausted.

Best Way to call Dynamically an stored procedure

Hi Guys,
Here my question... I need to call dynamically to an stored procedure...
- the stored procedure can change, the name , the number of parameters
- the called stored procedure can contain output parameters.
lv_sql := 'BEGIN '|| lv_program_name || ' ( ' || get_parameters(lv_program_name) || '); END;';
get_parameters function generates an string depeding on the number of parameters that this function reads from the
oracle dictionary (i.e: ':1,:2,:3,:4......... )
then the dynamyc code must be executed as follow
execute immediate lv_sql
using .................................?????????
The issue that I am facing is how to handle the "using clause".... since before that I ran the program I dont know how many parameters the program will have...
Please your help... (or suggestion to solve in another way)
...:::OKMMAN:::...

About "Satyaki_De " comment,
Since I dont know the stored procedure to be called, I cant know the number of parameters and its type to be returned... I mean.. to use the clause "using ...." in static way...
By now, I am creating dinamically a stored procedure... I am building a stored procedure that calls to the "unknown" stored procedure... reading the data dictionary and building dynamically the "Using...." clause... but I dont like ... since probably in production enviroment I will not have that kind of grants....
Regarding the link... I didn't know that new type... ! That's will solve the type issue... but still is pending the number of variable to provide to the "using" clause...

Calling a procedure dynamically in forms

Hi all
I'm using Oracle 6, is there anyway to call a procedure dynamically, i mean the procedure called differs according to a certain condition. The procedure is local in the form not in the database, how can this be achieved

I'm searching for a way to call the procedure as follows
proc||cond for exampleBut why? What is the purpose to do like this? Any efficiency or any logical reason?
Another option You can create one procedure and call the code depend on parameter you pass like
PROCEDURE MY_PROC(pCond IN NUMBER) IS
BEGIN
IF pCond=1 THEN
    -- Do something here...
ELSIF pCond=2 THEN
   -- Do something here...
ELSE
   -- Do something here...
END IF;
END;And while calling the procedure you can call the procedure by passing the value of pCond upon your requirement like
MY_PROC(<parameter value>);But still the IF CONDITION exists either you use inside or outside the procedure.

Unable to call a procedure from inside a another procedure

Dear members
I am trying to call a procedure from inside an another procedure.Both the procedures are present within the same package.I am trying to call the second procedure just before the end of the first procedure.Both the procedures are compiling fine but the tables are not getting populated inside the second procedure.Also the DBMS_OUTPUT statements present in second procedures are not getting displayed.(I feel the second procedured is not getting called).

How to call a procedure with refcursor from another plsql unit

example I created a pkg with the a procedure that returns a REFCURSOR.
Now I need to call this procedure from another pkg and use the refcursor values in other pkg.
Help please.......
PROCEDURE CustomerSite_Get (p_Registry IN VARCHAR2,
p_CustomerNumber IN VARCHAR2, p_Cursor IN OUT t_cursor);
PROCEDURE CustomerSite_Get (p_Registry IN VARCHAR2,
p_CustomerNumber IN VARCHAR2, p_Cursor IN OUT t_cursor)
IS
-- 0903: Include BillToName
BEGIN
OPEN p_Cursor FOR
     SELECT S.LOCATION CustomerSite, S.SITE_USE_ID CustomerSiteID, C.CUSTOMER_NAME BillToName
     FROM RA_CUSTOMERS C,
RA_ADDRESSES A,
RA_SITE_USES S,
UWA_REGISTRY R,
UWA_REGISTRY_BILL_TO B
     WHERE C.CUSTOMER_ID = A.CUSTOMER_ID
     AND A.ADDRESS_ID = S.ADDRESS_ID
     AND S.SITE_USE_ID = B.SITE_USE_ID
