SQL Truncate Query

[Gregg123]

Hi Guys,
I'm using Splunk with DB Connector and all seem to work fine. The only problem is that when I go to "Run SQL queries" and click on the DB Query button to execute Truncate statement (I'm connected to Postgres DB) the command doesn't actually do anything and data stays in the table. Selecting and other queries work fine. What seems to be a problem?
When I set up the connection I did select the dialect to be Postgres so such typical for Postgres query should be understood. And, I'm an admin so I do have privileges to delete (truncate) tables.
Any suggestions?
Thanks
Greg

Yes, I'm perfectly aware of this fact. If dbconnect is in read only mode such query will cause an error to appear at the top of the browser's window. So, Splunk will actually inform you about this, and states that this is read only connection etc.
I fixed that, and this isn't a problem.
Something else prevents Truncate query to be executed.

Are you aware that by default dbconnect only has only read permissions on the database ?
