Oracle PL/SQL - SELECT INTO Statement for Assigning Row to Record Variable

Introduction

The syntax of a simple SELECT INTO statement is:

SELECT select_list INTO record_variable_name FROM table_or_view_name; 

For each column in select_list, the record variable must have a corresponding, type-compatible field.

The columns in select_list must appear in the same order as the record fields.

In the following code, the record variable rec1 represents a partial row of the emp table-the columns last_name and empid.

The SELECT INTO statement selects from emp the row for which job_id is 'CODER' and assigns the values of the columns last_name and empid in that row to the corresponding fields of rec1.
