    Rename columns (Database Engine)

    Applies to: SQL Server 2016 (13.x) and later versions Azure SQL DatabaseAzure SQL Managed InstanceSQL database in Microsoft Fabric

    You can rename a table column in SQL Server by using SQL Server Management Studio or Transact-SQL.

    Limitations

    Renaming a column doesn't automatically rename references to that column.

    You must modify any objects that reference the renamed column manually. For example, if you rename a table column and that column is referenced in a trigger, you must modify the trigger to reflect the new column name.

    Use sys.sql_expression_dependencies to list dependencies on the object before renaming it.

    Renaming a column doesn't automatically update the metadata for any objects which all columns (using ) from that table. For example, if you rename a table column, and that column is referenced by a non-schema-bound view or function that selects all columns (using ), the metadata for the view or function continues to reflect the original column name.

    Refresh the metadata using sp_refreshsqlmodule or sp_refreshview.
