Hi everybody!
I'm trying to put " ACCEPT variable_column PROMPT 'number of columns'" into a procedure or function like:
CREATE OR REPLAC EPROCEDURE proc_number (table_name VARCHAR2) IS
ACCEPT variable_column PROMPT 'number of columns?
variable_column NUMBER(10) := &variable_column;
...

But this action doesn't works...
Do you know what I'm trying to do ?
Thanks !

Prompting for values is always closely related to the client/application your are using.

So, prompting for values within a procedure won't work at all.
Why not use an additional argument to your procedure? That's what they are for.

Simply like this:
CREATE OR REPLACE PROCEDURE proc_number (table_name VARCHAR2 , another_argument NUMBER ) IS

Yes, but I want to use a substitution variable, so, instead of the classic "Enter value for <substitution variable", I want my own message.
You knwo ?

Which client/application are you going to use to call the procedure?
Prompting for values is something done by the client/application and not from within the database itself.

I don't know nor use iSQL*Plus, but I'm sure there's plenty of documentation on it, maybe you should have a read Wink

Hi everybody,
this is an example of my request:
create or replace procedure add_column(table_name VARCHAR2) IS
column_name VARCHAR2(20) := '&column_name';
column_type VARCHAR2(20) := '&column_type';
request VARCHAR2(40) := 'alter table ' || table_name || ' ADD (';
tmp VARCHAR2(15);
BEGIN
tmp :=
case 
when column_type = 'Caracteres' THEN
'VARCHAR2(40)'
when column_type = 'Nombres' THEN
'NUMBER(15)'
END;
request := request || column_name || ' ' || tmp || ' )';
EXECUTE IMMEDIATE request;
END add_column;
/

But the subsitution variable are asked during the procedure creation, and no when I call my procedure.
How can I do that? Is it possible ?
Thank

You can't.
As already said, procedure executes on SERVER, substitution variables are CLIENT objects.

This is the same question as the previous one, don't start a new topic for that.

Regards
Michel
