AW: null values

Rolf,

first thx for your help. It only works with the coalesce-function.

The reason i use the sqlda, is that my sqlrpg program can
process all types of sql-statements.

in your example you fetch the result into the file-field or in a
helpfield of the same type and length.
My fetch looks like this:
                              
c/exec sql                    
c+ fetch c0 for 1 rows        
c+ using descriptor :sqlda    
c+ into :universal_ds              
c/end-exec                    
                             
it's completly universal.

thx for help, stefan

------------------------------

Not quite sure what you want to accomplish,

I use a similar construct when searching for the
highest key

c+    select coalesce(max(xyzKey), 0) into :xyzKey from xyzTable

which needs no sqlda and places the desired value directly
into the variable of the requesting program
