I tried using null indicators before, but it wouldn't compile. Tried it again and it worked. I obviously had something wrong the first time.

Thanks

If a field is blank, I want to write a null when I do an INSERT.
There could be one or more nulls. Is there a good way to do this?
The only way I've found so far is a bunch of different INSERT
statements and IF/ELSE's.

Not sure what is the scenario; DDL and some example data might be more clear.

But if I understand correctly what was attempted to be expressed in that text, I think the following might assist; presumes an INSERT with VALUES clause:

INSERT INTO the_lib/the_table VALUES
( nullif( '' , :F1_value )
, nullif( '' , :F2_value )
)

The NULLIF scalar will produce a NULL-result if the value of the host variable named F1_value equates with the empty-string [varlen] or equates with all blanks for a fixed-length field. Thus the determination whether the NULL-value is the effect, is pushed into the database rather than being coded separately\before in the host-language.

From the description in the OP [above], seems unclear whether the IF\ELSE work is being used to set the NULL indicators, and perhaps the host-indicator-variables are already being supplied; e.g.:

INSERT INTO the_lib/the_table VALUES
( :F1_value :F1_ind )
, :F2_value :F2_ind )
)
