Syntax

BL_MAPFILE=YES | NO

Syntax Description

YES

specifies that a map file is used.

NO

specifies that a map file is not used.

Details

You can use this option to pass connection and table information in a text (map) file to the loader or export application during bulk loading or unloading. The SAS/ACCESS engine automatically creates and deletes the map file for each bulk loading or unloading.

Example: Passing Connection and Table Information

SAS uses the sasflt.flt98 map file in this example to provide the needed connection and table information for bulk loading.

LIBNAME sasflt 'SAS-data-library';
LIBNAME net_air ASTER user=myusr1 pwd=mypwd1
        server=air2 database=flights dimension=yes;

data net_air.flights98
       (bulkload=YES bl_mapfile=yes);
    set sasflt.flt98;
run;
