Although the most common use of job variables is to specify the value for an operator attribute, job variables can also be used for object names and other job script parameters. In the following example, the values for @ConsumerOperator and @ProducerOperator can be assigned in the global job variables file, in a local job variables file, in a tbuild command, or in a job script using the SET directive.
APPLY 'INSERT INTO TABLE xyz (:col1, :col2);' TO OPERATOR ( @ConsumerOperator  ) SELECT * FROM OPERATOR ( @ProducerOperator );
Job variable can also be used in a quoted string for DML and DDL statements:
'INSERT INTO TABLE ' || @TargTable || ' (:col1, :col2, . . ., :coln);'
