Issue

When you try to do a refresh of a Microsoft SQL Server extract, the following error occurs:

Errors occurred while reloading the data source.: [Errors for '<datasourcename>':, Error parsing filter for field '<fieldname>', ignoring filter.]

Environment

  • Tableau Server
  • Microsoft SQL Server 2012

Resolution

  1. Check if you have the correct driver for Microsoft SQL Server  2012 by selecting Control Panel > System and Security > Administrative Tools > ODBC > DriversSQL Server Native Client 11 should be on the list.
  2. If SQL Server Native Client 11 is not on the list, download and install the correct driver for SQL Server from the Drivers page.

Cause

  • The Microsoft SQL Server driver that is installed on the computer running Tableau Server is outdated.
  • If the issue is intermittent, you might be using a distributed installation of Tableau Server and only some of the computers have updated drivers.
