I am trying to import an excel file into SQL Server Management Studio and this error comes up:

An error occurred creating the configuration section handler for system.data: Column 'InvariantName' is constrained to be unique. Value 'MySql.Data.MySqlClient' is already present. (C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\machine.config line 157) (System.Configuration) ------------------------------ Column 'InvariantName' is constrained to be unique. Value 'MySql.Data.MySqlClient' is already present. (System.Data) ------------------------------ BUTTONS: OK ------------------------------

What would be causing this?

    Hi @Deborah Dollesin,

    Column 'InvariantName' is constrained to be unique. Value 'MySql.Data.MySqlClient' is already present.

    Please check the column named InvariantName.

    It seems that you are inserting a duplicate value to the column.

    You should change the value in the table or change the value in your excel file.

    Regards，
