The way in which a Teradata request is processed determines the type of response that is returned, and is controlled by the DBCAREA Request-processing-option. Normally, the request is executed as SQL statements and the responses contain the results (Request-processing-option 'E'). However, Request-processing-options 'P' and 'S' analyze but do not execute the request, and the responses contain information about the SQL statements, not their results. Request-processing-option 'B' combines the processing of both 'S' and 'E'.
