How to Call Procedure With Package Type Param In Oracle?

To call a procedure with a package type parameter in Oracle, you need to first create the package that defines the custom data type. Then, in the procedure declaration, specify the parameter using the package type. When calling the procedure, pass in the appropriate package type parameter.

For example, if you have a package called "employee_pkg" with a custom data type called "employee_type", and a procedure within the package called "update_employee", you would call the procedure like this:

1
2
3
4
5
6

DECLARE
  emp_record employee_pkg.employee_type;
BEGIN
  emp_record := employee_pkg.employee_type(123, 'John Doe', 'Manager');
  employee_pkg.update_employee(emp_record);
END;

In this example, we are creating an instance of the "employee_type" data type and passing it to the "update_employee" procedure within the "employee_pkg" package. Make sure to define the package and its data types before attempting to call procedures with package type parameters in Oracle.

How to pass a parameter to a procedure in Oracle?

In Oracle PL/SQL, you can pass parameters to a procedure by simply specifying the parameter list within the parentheses of the procedure declaration. Here is an example:

1
2
3
4
5
6
7
8
9

CREATE OR REPLACE PROCEDURE my_procedure (
    p_param1 IN VARCHAR2,
    p_param2 OUT NUMBER,
    p_param3 IN OUT DATE
)
IS
BEGIN
    -- procedure logic here
END;

In this example, the procedure my_procedure accepts three parameters: p_param1 as an input parameter of type VARCHAR2, p_param2 as an output parameter of type NUMBER, and p_param3 as an input/output parameter of type DATE.

When calling the procedure, you would pass the values for the parameters accordingly:

1
2
3
4
5
6
7
8

DECLARE
    v_val1 VARCHAR2(20) := 'value';
    v_val2 NUMBER; 
    v_val3 DATE := sysdate;
BEGIN
    my_procedure(v_val1, v_val2, v_val3);
    -- after the procedure call, v_val2 and v_val3 will have updated values
END;

In this call, v_val1 is passed as an input parameter, v_val2 is passed as an output parameter, and v_val3 is passed as both an input and output parameter.

What is declaring a type in Oracle?

Declaring a type in Oracle involves defining a new user-defined data type, known as an object type, to represent a structured data format. Object types can be used to define the structure of a table, a variable, or a function parameter. By declaring a type, you can create a custom data structure with specific attributes and behaviors that can be used in SQL and PL/SQL code.

What is a package type parameter in Oracle?

A package type parameter in Oracle is a parameter that is defined within a package specification or package body. It is a type of parameter that can be passed to subprograms (procedures or functions) within the package. The parameter allows for passing data or values between different subprograms within the same package. Package type parameters can be defined as constants, variables, or objects of a specific data type.
