SQL Indicator?

[macwheel99@xxxxxxxxxx]

What should I do to this line, so SQL not gripe about missing indicator when 
NULL & what will be the condition of the indicator if the result is null?

C* SELECT SUM(TQTY) INTO :ISSUES                     

Here's the error message I am getting:

Message . . . . :   Indicator variable required.                             
 Cause . . . . . :   A FETCH, an embedded SELECT, a CALL or a SET or 
VALUES   
   INTO statement has resulted in a null value, but an indicator variable 
was 
   not specified for host variable ISSUES.  The relative position of the 
host 
   variable in the INTO clause or parameter list is 4. If the host 
variable   
   name is *N, an SQLDA was 
specified.                                        
 Recovery  . . . :   Specify an indicator variable, and precompile the 
program
   again.     

It says this is happening at program line # 16498
16498
which happens to be a comment 
documentation                                                                

Here is the code which has been running fine for years:

 C*EXEC SQL                                             
 C* SELECT SUM(TQTY) INTO :ISSUES                       
 C* FROM            ITH WHERE TPROD=:IPROD              
 C*                       AND (TTYPE='CI' OR TTYPE='I') 
 C*                       AND TTDTE>=:DATLO             
 C*                       AND TTDTE<=:DATHI             
 C*                       AND TWHS>='21'                
 C*                       AND TWHS<='59'                
 C*END-EXEC                                             

Here is what I added (recent archives of the data) that apparently blew up

 C*EXEC SQL                                           
 C* SELECT SUM(TQTY) INTO :ISSUES                     
 C* FROM BAKBP813/ITH WHERE TPROD=:IPROD              
 C*                     AND (TTYPE='CI' OR TTYPE='I') 
 C*                     AND TTDTE>=:DATLO             
 C*                     AND TTDTE<=:DATHI             
 C*                     AND TWHS>='21'                
 C*                     AND TWHS<='69'                
 C*END-EXEC                                                      

There will be cases where there is no TQTY activity where it is looking to 
get a total of inventory consumed in the specified date range.
