ARFETCHMXAFTERDATA2
ARFETCHMXAFTERDATA2
This procedure is the same as ARFETCHMXAFTERDATA 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 after image of audit records for SQL/MX
objects. ARFETCHMXAFTERDATA2 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. ARFETCHMXAFTERDATA2 copies the data for all columns
from the after image of the current audit record into a buffer specified by the
application. ARFETCHMXAFTERDATA2 works with audit records of type UPDATE
(10), UPDATE FIELDCOMP (15), and INSERT (5).
return-code output
INT .EXT:ref:1
is a returned value indicating the outcome of this procedure.
request-bytemap input
STRING .EXT:ref:*
must be bytemap-length bytes long. The setting of the various bytes, however,
does not matter. request-bytemap and reply-bytemap must not overlap one
another.
reply-bytemap output
STRING .EXT:ref:*
is bytemap-length bytes long. Each byte represents a column in the output
buffer. Upon return, a byte is 0x00 if data is not present in the corresponding
column or 0xFF if data is present. If reply-bytemap is not large enough to
represent all of the columns in the returned output, then data about columns
