The SQL Server sqlvariant data type is not currently supported by the Microsoft JDBC driver. If a query is used to retrieve data from a table that contains a column of the sqlvariant data type, an exception will occur. There are two workarounds to fix this issue:

  • Use CAST to type cast the sqlvariant columns to the data type you want.


  • Use the jTDS driver to connect.
