How to Call Database Procedure in Oracle Forms?

You can call a database procedure in Oracle Forms as you call in Oracle Database itself using PL/SQL. Below are the examples:

Call a Database Procedure in Oracle Forms Examples

In the following case, it will simply call a database procedure by specifying its name followed by the semicolon.

BEGIN
   proc_emp_data;
END;

To call a database procedure from another schema, add the schema name before procedure name as shown below:

BEGIN
   /* It will call the procedure from emp_arch schema */
   emp_arch.proc_emp_data;
END;

Calling a database procedure with IN and OUT parameters in Oracle Forms. In the below example, it will call the procedure with IN parameter l_in_empno and getting the employee name in OUT parameter l_out_name.

DECLARE
   l_in_empno    emp.empno%TYPE;
   l_out_ename   emp.ename%TYPE;
BEGIN
   proc_emp_data (l_in_empno, l_out_ename);
END;

Calling a database procedure inside a package. In the below example, it will call the procedure same as above but from a database package by specifying its name before the procedure, for example, db_package_name.db_procedure_name.

DECLARE
   l_in_empno    emp.empno%TYPE;
   l_out_ename   emp.ename%TYPE;
BEGIN
   pkg_emp.proc_emp_data (l_in_empno, l_out_ename);
END;
