Import Package Error - Cannot Convert between Unicode and Non Unicode String Data Type

Question

I have made a dtsx package on my computer using SQL Server 2008. It imports data from a semicolon delimited csv file into a table where all of the field types are NVARCHAR MAX.

Answer 1

Sometime we get this error when we select static character as a field in source query/view/procedure and the destination field data type in Unicode.

Below is the issue i faced: I used the script below at source

and got the error message Column "CATEGORY" cannot convert between Unicode and non-Unicode string data types. as below: error message

Resolution: I tried multiple options but none worked for me. Then I prefixed the static value with N to make in Unicode as below:

SELECT N'STUDENT DETAIL' CATEGORY, NAME, DATEOFBIRTH FROM STUDENTS
UNION
SELECT N'FACULTY DETAIL' CATEGORY, NAME, DATEOFBIRTH FROM FACULTY
