The %ROWTYPE attribute gives a record type which represents a row in a table (or view). The record can store the whole row of data selected from the table or fetched from a cursor or strongly typed cursor variable. In the illustration below, you declare two records.

DECLARE
emp_rec emp%ROWTYPE;
CURSOR c1 IS SELECT deptno, dname, loc FROM dept;
dept_rec c1%ROWTYPE;
