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))
分页存储过程，SQL 2000 数据库下使用的：
-- =============================================
-- DocumentName 分页存储过程 SQL 2000数据库下使用的
-- 描述 利用SQL查询语句进行分页
-- 输入
-- {
-- @SQL : SQL查询语句,示例：'Select * from [TableName]'
-- @Order : 排序,示例：[ColumnName] [ASC | DESC]
-- @CurPage : 当前页,示例：0..9
-- @PageRows : 每页显示的行数,示例：0..9
-- @TotalRecorder: 查询记录总数(输出参数)
-- @IsXML : 表示返回的结果，0表示以表格形式记录，1表示以XML格式返回记录；默认为0
-- }
