"Executing Query" Runs Indefinitely Using Set with Oracle

Issue

When using a Set with a live connection to Oracle, "Executing Query" runs indefinitely.

Environment

  • Tableau Desktop
  • Oracle

Resolution

Work with your DBA to adjust the Oracle field used in the set so it does not allow null values (is non-nullable.) 
 

Cause

This delay is caused by a null check. The null check is bypassed when the field does not allow null values.
