分页存储过程 排除重复行
分页存储过程 因为使用ROW_NUMBER() 所以不能使用distinct去掉重复的行。请教如何修改才能去掉重复的行
Create PROCEDURE [dbo].[GetRecordFromPage]
@SelectList VARCHAR(2000), --欲选择字段列表
@TableSource VARCHAR(100), --表名或视图表
@SearchCondition VARCHAR(2000), --查询条件
@OrderExpression VARCHAR(1000), --排序表达式
@PageIndex INT = 1, --页号,从0开始
@PageSize INT = 10 --页尺寸
AS
BEGIN
IF @SelectList IS NULL or LTRIM(RTRIM(@SelectList)) = ''
BEGIN
SET @SelectList = '*'
END
PRINT @SelectList
SET @SearchCondition = ISNULL(@SearchCondition,'')
SET @SearchCondition = LTRIM(RTRIM(@SearchCondition))
IF @SearchCondition <> ''
BEGIN
IF UPPER(SUBSTRING(@SearchCondition,1,5)) <> 'Where'
BEGIN
