Some
SAS/ACCESS software products
support a DATA step interface. This support enables you to read data
from your DBMS by using DATA step programs. Some products support
both reading and writing in the DATA step interface.
The DATA step interface
consists of four statements:
-
The INFILE statement identifies
the database or message queue to be accessed.
-
The INPUT statement is used with
the INFILE statement to issue a GET call to retrieve DBMS data.
-
The FILE statement identifies the
database or message queue to be updated, if writing to the DBMS is
supported.
-
The PUT statement is used with
the FILE statement to issue an UPDATE call, if writing to the DBMS
is supported.
The following example
updates data in an IMS database by using the FILE and INFILE statements
in a DATA step. The statements generate calls to the database in the
IMS native language, DL/I. The DATA step reads BANK.CUSTOMER, an existing
SAS data set that contains information about new customers, and then
it updates the ACCOUNT database with the data in the SAS data set.
data _null_;
set bank.customer;
length ssa1 $9;
infile accupdt dli call=func dbname=db ssa=ssa1;
file accupdt dli;
func = 'isrt';
db = 'account';
ssa1 = 'customer';
put @1 ssnumber $char11.
@12 custname $char40.
@52 addr1 $char30.
@82 addr2 $char30.
@112 custcity $char28.
@140 custstat $char2.
@142 custland $char20.
@162 custzip $char10.
@172 h_phone $char12.
@184 o_phone $char12.;
if _error_ = 1 then

SAS/ACCESS products
that provide a DATA step interface, the INFILE statement has special
DBMS-specific options that enable you to specify DBMS variable values
and to format calls to the DBMS appropriately. See the
SAS/ACCESS
documentation for your DBMS for a full listing of the DBMS-specific
INFILE statement options and the Base SAS INFILE statement options
that can be used with your DBMS.
