Hi Everyone,
I am a newbie here. I am trying to import data from flat file to SQL DB using SSIS. I have GUID data which i am importing into uniqueidentifier field.
My flow is as "Source File" -> Derived Column (Convert to GUID) -> Data Conversion -> OLEDB destination
It works fine as far as there is a valid GUID data in the source, but it fails when there is a "NULL / Empty". However i made that field to ignore failure and it successfully passed by.
But I feel it's not an optimal solution to ignore the error and pass through. Please advice.
Any suggestions would be much appreciated except "Not Possible :P" as I seen enough.
I tired -- User == "" ? "" : (DT_GUID)("{" + User + "}")
but it has a syntax error
Version using SQL 2012.
Thanks in advance,
newbie 🙂

what exactly you want to do with GUID column having null value?

Want to keep in the original table?

OR

want to Ignore this data

OR

Want to place a new GUID?

What is "User" in your expression?

Regarding the empty GUIDS, what is the exact error that you get?

Try setting the property "Retain null values from the source as null values in the data flow" to true in the flat file source.

Thanks for your quick response.

I would like to import as it is. I dont want to ignore the rows which has null GUID.

It's acutally child records which may sometimes doesnt have a GUID associated with it.

I didn't say anything about ignoring rows.

If the field is empty in the flat file, it can be imported as a NULL value.

Perfect that helps, Thanks everyone for looking into this,

It is resolved and I am closing this.

Resolution :

It got resolved by setting the property

"Retain null values from the source as null values in the data flow"

to true in the flat file source.
