Microsoft SQL Data Warehouse Table Settings

For more information on creating these connections, see Microsoft SQL Data Warehouse Connections.

Steps:

1. Select location: Navigate the  Azure Synapse Analytics (Formerly Microsoft SQL DW) browser to select the schema to which to publish.
   1. To create a new table, click Create a new table.
2. Select table options:
   1. Table name:
      1. New table: enter a name for it. You may use a pre-existing table name, and schema checks are performed against it.

      2. Existing table: you cannot modify the name.

   2. Output schema: To change the schema to which you are publishing, click the connection icon in the sidebar. Select a different schema.

   3. Optional table types: The following options may be available:

      1. Publish as external table: Output is published as an external table to the specified location in your storage layer. Otherwise, the table is published as a managed table.

         NOTE: When publishing to an external table, the output file type is Parquet.

   4. Publish actions: Depending on your selection or selections above, the following publishing actions on the table are supported. For more information, see "Publish Actions" below.

      1. Create new table every run: Each run generates a new table with a timestamp appended to the name.

      2. Append to this table every run: Each run adds any new results to the end of the table.
         
         

         NOTE: Appending the table is not supported for external tables.

      3. Truncate the table every run: With each run, all data in the table is truncated and replaced with any new results.

         NOTE: Truncating the table is not supported for external tables.

      4. Drop the table every run: With each run, the table is dropped (deleted), and all data is deleted. A new table with the same name is created, and any new results are added to it.
         
         

         NOTE: If the target is an external table, you can only drop the table when you first re-run a job to the target, after which you can choose to recreate the target as a managed or external table.

3. To save the publishing action, click Add.
