Hello All,
In SS EE I have nulls in a column. I want to select and eventually change to a zero (its a smallint column). I've tried selecting 'null', 'dbnull',
etc. Then I read about the ISNULL function. From the example I got, I received the "...require s 2 arguments...." error. Read up on it but it
doesn't click with me.
Could someone explain the error? And secondly, how to select null fields?
Thanks,
Hexman
=============== ======= Code Below =============== =
use CNDB
select * from cnmaster
where isnull(cnpick)
Msg 174, Level 15, State 1, Line 3
The isnull function requires 2 argument(s) 2 8305
Hello Hexman,
SELECT * FROM Table WHERE Field IS NULL
The change to zero SQL looks like:
UPDATE Table SET Field = 0 WHERE Field IS NULL
The ISNULL function converts a null value into a non-null value.. so..
SELECT Field AS NullField, ISNULL(Field, 0) AS NotNullField FROM Table
....would return ALL records, but report any null values in Field as zero,
without changing the underlying data.
ISNULL() is a reporting function.. not a data changing function.

The "toupper" function imposes a further constrait in that the value
