sql server 2005 ssis error when creating a derived column

Hi,
    I am creating a package in SSIS that imports data into a sql server 2005 database table from a csv file.
The csv file has columns, first name, last name and I want to create a derived column  called Full_ name.
ssisThe expression I am using is SET Full_Name = first name +' ' + last name
which works fine in t-sql  but I am getting the following error in ssis..

Any help appreciated. Thanks

The expression might contain an invalid token, an incomplete token, or an invalid element. It might not be well-formed, or might be missing part of a required element such as a parenthesis.

Try something like this:

SET Full_Name= [first name]+' ' +[last name]

if SQL objects have space or other special chars in their name they must be enclosed in sqare brakets.

Just put

[first name]+' ' +[last name]

no need to set FullName.

Sorry to say but this is not possible in SQL query. The expresion above should be something like for T-sql to work:

UPDATE TABLE table_name SET Full_Name = [first name] +' '+ [last name]

or if you are using a variable should be something like:

SET @Full_Name = (SELECT [first name] +' '+ [last name] )


And BTW your full_name is defined as varchar (50) as pe above schreenshot so if first name +' ' + last name is longer than that you know what hapens.

good luck!
