sql server更新一列为行号

注：引用自http://blog.csdn.net/lenovouser/article/details/52281726

查询显示行号：

SELECT
    row_number () OVER (ORDER BY orderby_id) AS rowNumber
FROM
    table_name;

 

更新一列为行号：

UPDATE table_name
SET new_row = t1.rowid
FROM
    (
        　　　　select table_pk,
        row_number () OVER (ORDER BY orderby_id) AS rowid
    FROM
        table_name
    ) 　　　　
) AS t1
WHERE
    t1.table_pk = table_name.table_pk;
