Plsql program for updating

Inserting and Updating with Records As you have seen, PL/SQL makes it very easy to populate a record from a row in a table.But what if you want to change the contents of a row in a table by using a record?Suppose I have an employees table in an application that looks like this: CREATE PROCEDURE process_employee ( employee_id_in IN omag_employees.employee_id%TYPE) IS l_employee_id omag_employees.employee_id%TYPE; l_last_name omag_employees.last_name%TYPE; l_salary omag_employees.salary%TYPE; BEGIN SELECT employee_id, last_name, salary INTO l_employee_id, l_last_name, l_salary FROM omag_employees WHERE employee_id = employee_id_in; END; (Note that I use suffixes in my parameters to indicate their mode.

By using %ROWTYPE to declare the record, I also tell Oracle Database that this procedure the omag_employees table.PL/SQL offers special syntax in both the INSERT and UPDATE statements so that you can easily use records to perform those data manipulation language (DML) operations as well.The most common form of an INSERT statement is where column_list is the list of columns that will be populated on insert and expression_list is the list of expressions that will be assigned to their respective columns.It also takes a look at record types, which enable you to work with records that are not necessarily related to a relational table.Declare a Record with %ROWTYPE PL/SQL makes it very easy to declare records that have the same structure as a table, a view, or the result set of a cursor by offering the %ROWTYPE attribute.
