Hi,

I need to convert NUMERIC(10) datatype to NVARCHAR(10) in Parallel Job from desinger. when i change the type and execute it throws error.

is there a way to do it.

Thanks,
Vindy

What did you try and what error did you get?

I changed the datatype in designer from numeric to nvarchar and i try to run the job i get the following:


Error when checking operator: When binding output schema variable "resRec": When binding output interface field "NOMINATION_KEY" to field "NOMINATION_KEY": Implicit conversion from source type "decimal[10,0]" to result type "ustring[max=10]": Not enough room in ustring for decimal[10,0].

What should i do to convert type in desinger.

Thanks,

Let me clarify. You simply changed the data type - you did not use any explicit data type conversion function. Is this correct?

yes you are correct. Is that the correct way to do, if not how could i go ahead in doing the change.

That is not the correct way to do this, even though it is allowed. There is a modify stage which is designed to do conversions such as this.

Or even the transformer stage which has Parallel Job Functions, specifically conversion functions, to perform this.

Hi I guess In the transformer,
left pane bottom put the datatype of the source
and in the right pane bottom put the datatype of the target

Now in the drag and drop canvas
right click on the derivation part,
u can see the type conversion functions
and which ever conversion u want u can go ahead
this will eliminate the warnings tooo
