Failed to retrieve data for this request. (Microsoft.SqlServer.Management.Sdk.Sfc)

An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)

A severe error occurred on the current command.  The results, if any, should be discarded. (.Net SqlClient Data Provider)
