Problem Note 38580: Calling a stored procedure with a null parameter in SAS/ACCESS® Interface to DB2 might result in a -804 DB2 error
 |  |  |  |  |
For SAS/ACCESS Interface to DB2 in the z/OS operating environment, an error similar to the following might occur upon invocation of a stored procedure.
DB2 execute error DSNT408I SQLCODE = -804, ERROR: AN ERROR WAS FOUND IN THE APPLICATION PROGRAM INPUT PARAMETERS FOR THE SQL STATEMENT, REASON 09
The error occurs when you call the stored procedure and you use a null parameter, as shown in the following SQL procedure:
proc sql;
connect to db2(ssid=db2p);
select * from connection to db2(call SAS.SASPROC(''));
quit;
This error occurs because of a change that IBM made to DB2 9 in which a character that is an empty string now results in an error. This error does not not occur with DB2 Version 8.
The workaround is to specify the null parameter with a macro and then reference the macro in the invocation, as shown in the following example:
%let p='';
proc sql;
connect to db2(ssid=db2p);
select * from connection to db2(call SAS.SASPROC(:p));
quit;
