To declare an identifier for a non-default database to be accessed in subsequent embedded SQL statements.

Prerequisites

You must have access to a username on the non-default database.

Syntax

Keywords and Parameters

db_name

is the identifier established for the non-default database.

Usage Notes

You declare a db_name for a non-default database so that other embedded SQL statements can refer to that database using the AT clause. Before issuing a CONNECT statement with an AT clause, you must declare a db_name for the non-default database with a DECLARE DATABASE statement.
