Unicode Collation Error

If you have such an error when you are trying to execute any SQL command:

CDbCommand failed to execute the SQL statement: SQLSTATE[HY000]: General error: 10007 Unicode data in a Unicode-only collation or ntext data cannot be sent to clients using DB-Library (such as ISQL) or ODBC version 3.7 or earlier. [10007] (severity 5) [(null)]

There are some solutions for this matter. The first and the simplest is to change any data type from unicode type (nvarchar, ntext, nchar) to non-Unicode support type such as varchar, char, text. The next solution is to install the most update ODBC. And the last solution is using casting like the following :

SELECT CAST(field1 AS TEXT) AS field1 FROM table

It took me half days to find the solution for such simple problem. Wish this helps you.
