三种SQL分页查询的存储过程代码

代码如下:


--根据MAX(MIN)ID
CREATE PROC [dbo].[proc_select_id]
@pageindex int=1,--当前页数
@pagesize int=10,--每页大小
@tablename VARCHAR(50)='',--表名
@fields VARCHAR(1000)='',--查询的字段集合
@keyid VARCHAR(50)='',--主键
@condition NVARCHAR(1000)='',--查询条件
@orderstr VARCHAR(500),--排序条件
@totalRecord BIGINT OUTPUT--总记录数
AS
IF ISNULL(@orderstr,N'')=N'' SET @orderstr=N' ORDER BY '+@keyid+N' DESC '
IF ISNULL(@fields,N'')=N'' SET @fields=N'*'
IF ISNULL(@condition,N'')=N'' SET @condition=N'1=1'
DECLARE @sql NVARCHAR(4000)
--IF(@totalRecord IS NULL)
--BEGIN
SET @sql=N'SELECT @totalRecord=COUNT(*)'
+N' FROM '+@tablename
+N' WHERE '+@condition
EXEC sp_executesql @sql,N'@totalRecord INT OUTPUT',@totalRecord OUTPUT
--END
IF(@pageindex=1)
BEGIN
