Thank you

I am now trying this one, but I face the following error.

Do you know how can I adapt the var types to my data base?

ERROR DB Loader 3:8 The input column type at index 1 is “VARCHAR”, the database column type is “NVARCHAR”.  
ERROR DB Loader 3:8 The input column type at index 2 is “VARCHAR”, the database column type is “NVARCHAR”.  
ERROR DB Loader 3:8 The input column type at index 3 is “VARCHAR”, the database column type is “NVARCHAR”.  
ERROR DB Loader 3:8 The input column type at index 4 is “VARCHAR”, the database column type is “NVARCHAR”.  
ERROR DB Loader 3:8 The input column type at index 5 is “VARCHAR”, the database column type is “NVARCHAR”
