| declare @sql varchar(8000)select @sql = 'select name as [' + @r1 + '] from customer'exec (@sql)This has security implications though.==========================================Cursors are useful if you don't know sql.SSIS can be used in a similar way.Beer is not cold and it isn't fizzy. |

The above code is not valid statement becuase you cannot use variable as alias name. Noty sure why you did not get any error.Also make sure to read this www.sommarskog.se/dynamic_sql.htmlMadhivananFailing to plan is Planning to fail |
