If you don't want to add a scalar function to each nullcapable column, you should add indicator variables for all column that can return NULL values.are you saying we should standardize on adding a indicator variable on all host variables?
1. NULL values are values outside the valid range and must be checked--
separately.
2. You can either convert a NULL value into a default value by using a
scalar function COALESCE(YourCol, '') oder IFNULL(YourCol, '') 3. You
can use an indicator variable (defined as 5I 0) that must be specified
immediately after the host variable to receive the value separated
only with a blank (no comma!).
If a NULL value is returned the Indicator Variable is set to -1
otherwise it is set to *ZERO.
SQLCODE <> 100 means:
1. All Records that are correct (SQLCODE = 0) 2. All Records where a
warning is returned (SQLCODE > *Zeros and NOT 100) 3. All erroneous
records (SQLCODE < *Zeros) where no values are returned.
I'm quite sure you'll get the SQLCODE -305 (Indicator variable
required)

Betreff: SQL -not returning records with null values
we have been coding our loops as follows:
dow sqlcod <> 100
....fetch records
if sqlcod<> 100
... write subfile, or write report line
evidently, the records with nulls return the 100?
we knew we should have had more records on the display, but when we
changed the if to "sqlcod = 0"
we received the records with null fields.
is this the proper fix, or is something else going on?
