Issue

The initial extract was published with a column that contains date/time values. After upgrading Tableau Server the extract refreshes, and that column converts to string values.

Environment

  • MS SQL Server

Resolution

Download and install the latest version of MS SQL driver.

Cause

The driver has become outdated and was incorrectly interpreting the date/time fields.
