USE

Specify or clear the context for the query session.

note

In the SQL Runner, the USE command only works with multi-statement SQL commands and scripts. USE also does not apply to table references in saved views.

Syntax 
USE [ { <path> | { REF[ERENCE] | BRANCH | TAG | COMMIT } <reference_name> }
 [ IN <catalog_name> ] ]

Parameters​

<path> String   Optional

The path that you want to use. By not specifying any parameters, you can clear the context for the query session.

{ REF[ERENCE] | BRANCH | TAG | COMMIT } <reference_name> String   Optional

You can also use these Arctic references to inform the session:

  • REF: Changes the reference to the specified branch, tag, or commit.
  • BRANCH: Changes the reference to the specified branch.
  • TAG: Changes the reference to the specified tag.
  • COMMIT: Changes the reference to the specified commit. Commit hashes must be enclosed in double quotes (for example, “ff2fe50fef5a030c4fc8e61b252bdc33c72e2b6f929d813833d998b8368302e2”).

IN <catalog_name> String   Optional

The name of the Arctic catalog where you want to change the reference. When this parameter is not used, the current Arctic catalog in the query context is used.

Examples​

Clear the context for the query session 
USE;
Each query run after this command in the same session will assume the specified path as the context 
USE Samples."samples.dremio.com";
Use the specified branch as the reference for the current query session 
USE BRANCH myBranch
   IN myCatalog;
