Dear All,

I am performing a data import on the SQL server. Due to fact
that I use the excel file as a source. Some of cells in excel are
actually empty, they become NULL fields after importing into the SQL
server. Actually I want these fields are empty string instead of NULL.
Does SQL server has any approach to make these fields to be empty
string instead of NULL when importing?? Or is there any store
procedure exist for converting the fields to empty string?

Thanks for your kind attention.

Benny

Since I don't know how you import the data, I can't really say what
you could do in that end.

Once the data is in SQL Server, you can say:

UPDATE tbl
SET col = ''
WHERE col IS NULL

I use DTS import/export wizard to import the data from the Excel file.
So is there any ways to replace the NULL fields with empty string
beside using query to update the fields to empty string?

Sorry, I don't use DTS so I don't know. But I want to point out the
necessity of providing people full information about what you are
doing.

If you don't get any replies, consider asking in
microsoft.public.sqlserver.dts. (Available on msnews.microsoft.com if your
ISP does not have it.)

Also check out the FAQ on http://www.sqldts.com.

With DTS, you can transform the data before it gets imported. That's the
'T' in 'DTS'. When moving an Excel spreadsheet to SQL Server, there is a
place in DTS where you select the worksheet from the Excel file. At this
location, there is a Transform button. You can do simple
transformations, or you can use VB code to do more complex
transformations.
