Title: SQL Command Set Description: This class is for holding sets of SQL commands necessary to complete a single SQL transaction. As an example, to completely insert a single object into a relational database, it may actually require inserts into multiple tables before the "transaction" is complete. The methods for putting SQL commands into this object do no checking to verify that the Strings contain valid SQL. Copyright: Copyright (c) 2001 Company: Nortel Networks
