.show table policy update command

Applies to: ✅ Microsoft FabricAzure Data Explorer

Show the table update policy. The update policy simplifies the process of syncing and updating data between two tables. When new data is inserted into the source table, a transformation query runs over this data to modify and insert the data into the target table.

Note

The source table and the table for which the update policy is defined must be in the same database. The update policy function schema and the target table schema must match in their column names, types, and order.

You must have at least Database User, Database Viewer, or Database Monitor permissions to run these commands. For more information, see role-based access control.
