这里记录些许个会经常用到的sql语句。

P.S.   [Your_Table]  = 你的表名, [nid] = 你表中的主键唯一列.

/*按分页数量取表记录中的数据*/
/*以nid排序, 取20条之后的10条*/SELECT TOP 10 *
FROM Your_Table
WHERE (nid NOT IN
          (SELECT TOP 20 nid
         FROM Your_Table
         ORDER BY nid))
ORDER BY nid

/*取传入条件记录的前一条数据*/
/*取 nid='533' 记录的前一条, 返回记录 nid='532'*/
SELECT *
FROM Your_Table
WHERE (nid =
          (SELECT MAX(nid)
         FROM Your_Table
         WHERE nid < 533))

/*取传入条件记录的后一条数据*/
/*取 nid='533' 记录的后一条, 返回记录 nid='532'*/		 
SELECT *
FROM Your_Table
WHERE (nid =
          (SELECT MIN(nid)
         FROM Your_Table
         WHERE nid > 534))
