DECLARE
The DECLARE statement can be used in a database procedure definition to declare a list of local variables for use in the procedure. If used, place it before the BEGIN clause of the database procedure definition.
Nullable variables are initialized to null. Non-nullable variables are initialized to the default value according to data type: character data types are initialized to blank, and numeric data types are initialized to zero. Any non-nullable variables declared without an explicit default value are initialized to the default value.
