Problem Note 41619: Using PROC FORMAT in conjunction with PROC SQL to access a database gives different results between SAS® 9.1.3 and SAS® 9.2
 |  |  |  |  |
Doing a query in SAS 9.1.3 against a Microsoft SQL Server table using SAS/ACCESS® Interface to Microsoft SQL Server returns correct results. SAS/ACCESS Interface to Microsoft SQL Server in SAS 9.2 passes a substring function, which returns an incorrect result. Using the LIBNAME option DIRECT_SQL=NOWHERE does not have an effect on the results. The following code produces different results between SAS 9.1.3 and SAS 9.2.
proc format;
value $target
'12345678'='*'
'67890123'='*';
run;
options sastrace=',,,d' sastraceloc=saslog nostsuffix;
proc sql details="reduce_put_bench$" _tree;
create table work.tmp as
select * from test.awh_phone2 AS Phone_phone
where put(Phone_phone.s_phone,$target.) = '*';
quit;
SAS 9.1.3 generates the following code:
SQLSRV_2: Prepared:
SELECT "s_phone", "r_phone", "date_time", "Duration" FROM "awh_phone2"
SAS 9.2 generates this code:
SELECT "s_phone", "r_phone", "date_time", "Duration" FROM "awh_phone" WHERE
( ( ({fn SUBSTRING( "s_phone", 1, 1)} IN (
'12345678' , '67890123' ) ) ) OR ( ({fn SUBSTRING( "r_phone", 1, 1)} IN (
'12345678' , '67890123' ) ) ) OR ({fn SUBSTRING(
"s_phone", 1, 1)} = '*' ) OR ({fn SUBSTRING( "r_phone", 1, 1)} = '*' ) )
The workaround is to change the format as follows:
proc format;
value $target(default=8)
'12345678'='*'
'67890123'='*';
run;
