"Error Code: 975DF5A2" Received in Tableau When Working With PostgreSQL UUIDs

Date de publication: Feb 24, 2026
Description

When a user connects to PostgreSQL and updates the data from Tableau Desktop, the following error occurs:

ERROR: operator does not exist: text=uuid
Hint: No operator matches the given name and argument types. You might need to add explicit type casts.
 Position: xxxx

Error Code: 975DF5A2

or

ERROR: function min(uuid) does not exist 
Hint: No function matches the given name and argument types. You might need to add explicit type casts.
Position: xxxx

Error Code: 975DF5A2

 

Cause

Two issues are involved:

  1. A PostgreSQL column of type uuid and it is not well supported by Tableau. 
  2. The casting is not presented on all tables when querying the database.

 

Résolution

Option 1

Hide the columns or replace tables with custom SQL that do not include these columns.
 

Option 2

Use custom SQL to explicitly cast that column to text. If there are multiple tables joined, make sure casting is presented on all the tables.
