For example, table definitions, indexes, constraints, and permissions are updated. When renaming a table, all objects and properties associated with the table are updated to reference the new table name. Rename the user defined database AdWorks This example renames the user-defined database AdWorks to AdWorks2. Rename a databaseĪpplies to: Analytics Platform System (PDW) only Renaming a table takes a shared lock on the DATABASE object, a shared lock on the SCHEMA object, and an exclusive lock on the table. In certain cases, views can become invalid needing a drop and recreate. Views will keep showing the old column name until an alter view is performed. When renaming a column, views aren't updated to reference the new column name. To resolve this issue, you can update each view to reference the new table name. Each view, inside or outside of the database, that references the former table name will become invalid. When renaming a table, views aren't updated to reference the new table name. To resolve this issue, you can either avoid using three-part names in views, or update the views to reference the new database name. For example, if the Sales database is renamed, a view that contains SELECT * FROM 1 will become invalid. This behavior applies to views both inside and outside the database. When renaming a database, all views that use the former database name will become invalid. You also can't rename any columns in an external table or a temp table. You can't rename a column that is used for the table's distribution. This example views a list of active or idle sessions and then terminates session 'SID1234'. Include 'SID' and the session number when invoking the KILL command. ![]() Sessions in Azure Synapse Analytics are prefixed by 'SID'. Use KILL cautiously since when a session is terminated any uncommitted work will be rolled back. To terminate a session, you can use the KILL command. If the table is in use, you may need to terminate sessions that are using the table. Renaming a table requires an exclusive lock on the table. You can't rename a table or database while it is in use. Instead of renaming, you can drop the external table, index, or view and then re-create it with the new name. You can't rename an external table, indexes, or views.
