How can a stored procedure be called from PL/SQL?EXECUTE procedure_name;EXEC procedure_name;

To call a stored procedure from PL/SQL, you can follow these steps:

1. First, you need to ensure that the stored procedure is already created in the database. If not, you need to create it.

2. Once the stored procedure is available, you can call it from a PL/SQL block. Here is a simple example of how to do it:

BEGIN
   procedure_name;  -- Call the procedure
END;
/

In this example, replace procedure_name with the name of your stored procedure.

3. If your stored procedure has parameters, you can pass them in the call like this:

BEGIN
   procedure_name(parameter1, parameter2, ...);  -- Call the procedure with parameters
END;
/

In this example, replace parameter1, parameter2, ... with the actual parameters you want to pass to the procedure.

4. After writing the PL/SQL block, you can execute it in your Oracle database environment. The stored procedure will be called within the PL/SQL block.

Note: The EXECUTE or EXEC command is a SQLPlus command in Oracle, not a PL/SQL command. You can use EXECUTE or EXEC to call a procedure directly from the SQLPlus environment, like this:

EXECUTE procedure_name;

or

EXEC procedure_name;

Again, replace procedure_name with the name of your stored procedure. If the procedure has parameters, you can pass them after the procedure name.
