Returns the result of executing sql-statement against connection.
Connection may be empty if there is a current connection, which is the case if the script is called from within a USoft instance with a call to SELECT USCSXSL.BLEND. In this case, the return value is the result of executing sql-statement against the current connection. This case is illustrated by the example below.
This example returns, in the form of an XML comment, the output of the INVOKE USMETA.TABLES call, which (if called from a USoft Application instance, as opposed to a USoft Definer instance) is an XML-formatted listing of metadata describing Logical Views.
