ARFETCHMXBEFOREDATA2

This procedure is the same as ARFETCHMXBEFOREDATA except that it uses byte

maps instead of bit maps. Byte maps are easier to use for languages that have

difficulty checking and setting bits.

This procedure retrieves column data from the before image of audit records for

SQL/MX objects. ARFETCHMXBEFOREDATA2 can only be used with data-fork audit

records for SQL/MX objects. The object type can be determined by checking the

OBJECTTYPE field in the ARRECORD. ARFETCHMXBEFOREDATA2 copies the

data for all columns from the before image of the current audit record into a buffer

specified by the application. ARFETCHMXBEFOREDATA2 works with audit records of

type UPDATE (10), UPDATE FIELDCOMP (15), and DELETE (3).
