A computed column is a virtual column that is not physically stored in the table, unless the column is marked PERSISTED. Is an expression that defines the value of a computed column. You do not specify columns because a FileTable has a fixed schema. ![]() table_name can be a maximum of 128 characters, except for local temporary table names (names prefixed with a single number sign (#)) that cannot exceed 116 characters.Īpplies to: SQL Server (Starting with SQL Server 2012 (11.x)).Ĭreates the new table as a FileTable.
