The USE command sets the specified database as the default database for subsequent queries. The database remains current until the end of the session or until another USE statement is issued. Tables from other databases can still be accessed, but must be indicated by including the database name in the table reference, database!table.
SQL must be set to MySQL before using the USE command in this way.
set sql to mysql USE hr; SELECT staff_no, lastname from staff; USE accounts; SELECT salesid from customer; USE hr; SELECT staff_no, lastname, customerno from staff, accounts!customer where staff.staff_no = accounts!customer.salesid;
