Hi,


I am loading a table with a data coming from csv file,

It has null values in it,

the column which has null is being used in stage variable and constraints,

if not used in constraints, and stage variable then it never drops the records...if used it does so.

i have used isnull to check if the column is null or not..if its null i am rejecting the record (in stage variable and constraints)

Please suggest ,

thanku

and these columns are nullable columns.

It would be easy for us to solve your problem if you can post your derivation.

Here is the derivation for value column:


before:if NUM(Trim((INP_1.Value))) = 1 or trim((INP_1.Value)) = ''
Then 0
else 1
AND

Now:
if NUM(Trim(NULLTOEMPTY(INP_1.Value))) = 1 or trim(NULLTOEMPTY(INP_1.Value)) = ''
Then 0
else 1


The records are not getting dropped but still the warning is there
saying
"APT_CombinedOperatorController,0: Null string argument."

Please suggest how to remove this warning;

Disable operator combination to isolate the stage that is generating the error.
Try using casing as per the manual for the function names, for example NullToEmpty().

while reading csv file you have a option Nullabe =yes/No

try that option

Hi,

As the warning still persists,

the job is aborting if the number of warnings is greater than 50

Please suggest how can i remove this warning.

Hi you can have a message handler defined to filter the warning from log if any of the specified methods didn't work.

Actually i have put up a check for a field comming from source which is nullable:
The transformer uses stagevariable as

If NUM((NullToEmpty(INP_1.Value))) = 1 or NullToEmpty(INP_1.Value) = '' then 0 else 1

if this not used it do not give any warning if used it gives warning;

and the source value INP_1.Value has null values in it

Hi,

Please let me know how to disable "operator combination"

thanku.

Hi Shivaranjani,

Try this may be it solves ur problem:

If IsNull(INP_1.Value) Then ""else(If Trim(INP_1.Value) =1 0r Trim(INP_1.Value) ='' then 0 else 1)


Cheers,

Hi Scorpion,

Thanks a lot its working now....
