How To Initialize Variables with Default Values?

Submitted by: Administrator
There are two ways to assign default values to variables at the time of declaration:

► Using key word DEFAULT - Appending "DEFAULT value" to the end of declaration statements.
► Using assignment operator - Appending ":= value" to the end of declaration statements.

The script below show you some examples of declaration statements with default values:

PROCEDURE proc_var_1 AS
domain VARCHAR2(80) := 'globalguideline.com';
price REAL DEFAULT 999999.99;
is_for_sale CHAR := 'N';
BEGIN
-- Executable statements
END;
