Oracle PL-SQL Interview Question:

What are % TYPE and % ROWTYPE? What are the advantages of using these over datatypes?

Submitted by: Administrator

% TYPE provides the data type of a variable or a database column to that variable.
% ROWTYPE provides the record type that represents a entire row of a table or view or columns selected in the cursor.
The advantages are : I. Need not know about variable's data type
ii. If the database definition of a column in a table changes, the data type of a variable changes accordingly.
