This article explores how you declare records, populate them with rows from a table, and even insert or change an entire row in a table by using a record.

It also takes a look at record types, which enable you to work with records that are not necessarily related to a relational table.

If the database administrator changes the maximum length of the last_name column to 200, for instance, this procedure’s status will be changed to INVALID.

Here _in indicates an IN parameter.) That is, however, an awful lot of code to write, read, and maintain.

A much better approach is to fetch that row of data into a record, and the best way to declare that record is as follows: CREATE PROCEDURE process_employee ( employee_id_in IN omag_employees.employee_id%TYPE) IS l_employee omag_employees%ROWTYPE; BEGIN SELECT employee_id, last_name, salary INTO l_employee FROM omag_employees WHERE employee_id = employee_id_in; END; When this procedure is compiled, PL/SQL looks up the structure of the omag_employees table and defines a record that has a field for each column in the table, with the same name and datatype.

It can also looks like this: select id, a, b from tb_target union all select id, a, b from tb_source Then, we've group records by all columns in this view and counting appearance by primary key (i.e.: id): select id, count(1) cnt group by id, a, b In group clause You must specify all columns, which can be updated/insert, and in counting specify only pk fields.

Here are the answers to the PL/SQL Challenge questions in last issue’s “Error Management” article: Answer 1: Choices (a), (c), and (d) all raise ORA-00001, also known as DUP_VAL_ON_INDEX inside PL/SQL code.
