SQL Server存储过程单条件分页的简单示例

这篇文章主要为大家详细介绍了SQL Server存储过程单条件分页的简单示例，具有一定的参考价值，可以用来参考一下。

感兴趣的小伙伴，下面一起跟随四海网的小编两巴掌来看看吧！

话不多说，请看代码：

代码如下：

SQLServer Procedure Pagination_basic：
ALTER PROCEDURE [qiancheng].[Pagination_basic] (
@Table_name VARCHAR (255),
--name of table
@Rows_target VARCHAR (1000) = '*',
--search rows 
@Rows_condition VARCHAR (1000) = '',
--the condition to find target (no where)
@Rows_order VARCHAR (255) = '',
--the rows to rank
@Order_type INT = 0,
-- *Q*C* 0 normal 1 down
@PageSizes INT = 10,
--the size of each page
@PageIndex INT = 1,
--current page
@ShowPages INT,
--whether show the pages *Q*C* 1-yes 0-no
@ShowRecords INT,
--whether show the record *Q*C* 1-yes 0-no
@Records_total INT OUTPUT,
--returned total records
@Pages_total INT OUTPUT --returned total pages
) AS
DECLARE @MainSQL_QC nvarchar (2000) --Main SQL sentence
DECLARE @Var_QC VARCHAR (100) --Temporary variate
DECLARE @Order_QC VARCHAR (400) --the sort to rank
SET @Records_total = 0
SET @Pages_total = 0
IF @ShowRecords = 1
OR @ShowPages = 1
BEGIN
IF @Rows_condition != ''
SET @MainSQL_QC = 'select @Records_total = count(1) from [' + @Table_name + '] where ' +@Rows_condition
ELSE
SET @MainSQL_QC = 'select @Records_total = count(1) from [' + @Table_name + ']' EXEC sp_executesql @MainSQL_QC,
 N'@Records_total int out' ,@Records_total OUTPUT
END
IF @ShowPages = 1
BEGIN
IF @Records_total <= @PageSizes
SET @Pages_total = 1
ELSE
BEGIN
SET @Pages_total = @Records_total /@PageSizes
IF (@Records_total %@PageSizes) > 0
SET @Pages_total = @Pages_total + 1
END
END
IF @Order_type = 1
BEGIN
SET @Var_QC = '<(select min'
SET @Order_QC = ' order by [' + @Rows_order + '] desc'
END
ELSE
BEGIN
SET @Var_QC = '>(select max'
SET @Order_QC = ' order by [' + @Rows_order + '] asc'
END
IF @PageIndex = 1
BEGIN
IF @Rows_condition != ''
SET @MainSQL_QC = 'select top ' + str(@PageSizes) + ' ' +@Rows_target + ' from [' + @Table_name + '] where ' + @Rows_condition + ' ' + @Order_QC
ELSE
SET @MainSQL_QC = 'select top ' + str(@PageSizes) + ' ' +@Rows_target + ' from [' + @Table_name + '] ' + @Order_QC
END
ELSE
BEGIN
IF @Rows_condition != ''
SET @MainSQL_QC = 'select top ' + str(@PageSizes) + ' ' +@Rows_target + ' from [' + @Table_name + '] where [' + @Rows_order + ']' + @Var_QC + '([' + @Rows_order + ']) from (select top ' + str((@PageIndex - 1) *@PageSizes) + ' [' + @Rows_order + '] from [' + @Table_name + '] where ' + @Rows_condition + ' ' + @Order_QC + ') as Tmep_QC) and ' + @Rows_condition + ' ' + @Order_QC
ELSE
SET @MainSQL_QC = 'select top ' + str(@PageSizes) + ' ' +@Rows_target + ' from [' + @Table_name + '] where [' + @Rows_order + ']' + @Var_QC + '([' + @Rows_order + ']) from (select top ' + str((@PageIndex - 1) *@PageSizes) + ' [' + @Rows_order + '] from [' + @Table_name + ']' + @Order_QC + ') as Tmep_QC)' + @Order_QC
END EXEC (@MainSQL_QC)

调用：execute pagination_basic 'UserDetail','*','','id','1','5','1','1','1','',''

主要是末尾的语句，拆分下来便是这样：

select top 每页数 列名 from [表名] where [排序字段名] <    --1 倒序输出若列 小于之前页数的最小值

(select min ( [排序字段名] )from --2 获得一个指定列名中的最小值并输出

(select top (当前页-1)*每页数 [排序字段名] from [表名] where [条件] [排序类型]) --3 选择之前页数总数据倒序输出

as Tmep_QC)--4 建立一个名为Tmep_QC的临时表--2 获得一个指定列名中的最小值并输出

and [条件] [排序类型]--1 倒序输出若列 小于之前页数的最小值
