Depending on the data source, you may have the option to specify the tables or queries that you want to connect to. In some cases, connecting to certain tables or queries in a Teradata data source, for example, causes the following error message to display and Tableau to close:

“Tableau has encountered a problem and needs to close.”
This issue can occur when the table or query contains “non-string” (binary or BLOB) data that is converted into a string data type. If the data contains “non-string” data, Tableau is unable to recognize it and displays the above message.

To resolve this issue, you can do one of the following tasks:
  • Hide columns that have “non-string” types. To hide columns (i.e., fields) in Tableau, right-click the field in the Data window, and then select Hide.
  • Exclude columns in the table or query that have “non-string” types from your connection.
