我是菜鸟！存储过程 where参数过长，执行无效，求解！！！

[路遥迢]

存储过程：
Create PROCEDURE SP
(
@Tables varchar(1000),
@PrimaryKey varchar(100),
@Sort varchar(200) = NULL,
@CurrentPage int = 1,
@PageSize int = 10,
@Fields varchar(1000) = '*',
@Filter varchar(1000) = NULL,
@Group varchar(1000) = NULL
)
AS
/*默认排序*/
IF @Sort IS NULL or @Sort = ''
SET @Sort = @PrimaryKey
DECLARE @SortTable varchar(100)
DECLARE @SortName varchar(100)
DECLARE @strSortColumn varchar(200)
DECLARE @operator char(2)
DECLARE @type varchar(100)
DECLARE @prec int
/*设定排序语句.*/
IF CHARINDEX('DESC',@Sort)>0
BEGIN
SET @strSortColumn = REPLACE(@Sort, 'DESC', '')
SET @operator = '<='
END
ELSE
BEGIN
IF CHARINDEX('ASC', @Sort) = 0
SET @strSortColumn = REPLACE(@Sort, 'ASC', '')
SET @operator = '>='
END
IF CHARINDEX('.', @strSortColumn) > 0
BEGIN
SET @SortTable = SUBSTRING(@strSortColumn, 0, CHARINDEX('.',@strSortColumn))
SET @SortName = SUBSTRING(@strSortColumn, CHARINDEX('.',@strSortColumn) + 1, LEN(@strSortColumn))
END
ELSE
BEGIN
SET @SortTable = @Tables
SET @SortName = @strSortColumn
END
Select @type=t.name, @prec=c.prec
FROM sysobjects o
JOIN syscolumns c on o.id=c.id
JOIN systypes t on c.xusertype=t.xusertype
Where o.name = @SortTable AND c.name = @SortName
IF CHARINDEX('char', @type) > 0
SET @type = @type + '(' + CAST(@prec AS varchar) + ')'
DECLARE @strPageSize varchar(50)
DECLARE @strStartRow varchar(50)
DECLARE @strFilter varchar(1000)
DECLARE @strSimpleFilter varchar(1000)
DECLARE @strGroup varchar(1000)
/*默认当前页*/
IF @CurrentPage < 1
SET @CurrentPage = 1
/*设置分页参数.*/
SET @strPageSize = CAST(@PageSize AS varchar(50))
SET @strStartRow = CAST(((@CurrentPage - 1)*@PageSize + 1) AS varchar(50))
/*筛选以及分组语句.*/

IF @Filter IS NOT NULL AND @Filter != ''
BEGIN
SET @strFilter = ' Where ' + @Filter + ' '
SET @strSimpleFilter = ' AND ' + @Filter + ' '
END
ELSE
BEGIN
SET @strSimpleFilter = ''
SET @strFilter = ''
END
IF @Group IS NOT NULL AND @Group != ''
SET @strGroup = ' GROUP BY ' + @Group + ' '
ELSE
SET @strGroup = ''
/*执行查询语句*/
EXEC(
'
DECLARE @SortColumn ' + @type + '
SET ROWCOUNT ' + @strStartRow + '
Select @SortColumn=' + @strSortColumn + ' FROM ' + @Tables + @strFilter + ' ' + @strGroup + ' orDER BY ' + @Sort + '
SET ROWCOUNT ' + @strPageSize + '
Select ' + @Fields + ' FROM ' + @Tables + ' Where ' + @strSortColumn + @operator + ' @SortColumn ' + @strSimpleFilter + ' ' + @strGroup + ' orDER BY ' + @Sort + '
'
)
GO



where 参数：当我只留下几个xxx like 执行成功
string temp = "(Sarxm LIKE '%" + this.textBox1.Text + "%') OR (Xb LIKE '%" + this.textBox1.Text + "%') OR (Mz LIKE '%" + this.textBox1.Text + "%') OR (Gj LIKE '%" + this.textBox1.Text + "%') OR (Sfzhm LIKE '%" + this.textBox1.Text + "%') OR (Whcd LIKE '%" + this.textBox1.Text + "%') OR (Hzhm LIKE '%" + this.textBox1.Text + "%') OR (Yytc LIKE '%" + this.textBox1.Text + "%') OR (Jg LIKE '%" + this.textBox1.Text + "%') OR (Xzz LIKE '%" + this.textBox1.Text + "%') OR (Nc LIKE '%" + this.textBox1.Text + "%') OR (Xqah LIKE '%" + this.textBox1.Text + "%') OR (Lxfs LIKE '%" + this.textBox1.Text + "%') OR (Zz LIKE '%" + this.textBox1.Text + "%') OR (Bz LIKE '%" + this.textBox1.Text + "%')";

求解！！！！！！！！！！

[让你望见影子的墙]

把数据类型改为varchar(8000)也不行？

[让你望见影子的墙]

如果还不行，那就只有分拆了。分拆的话，就是把过长的那一部分分成几部分，拆分合适的话，不会影响通用性的

[百年树人]

拆成几个字符串，然后拼凑

declare @sql1 varchar(8000)
declare @sql2 varchar(8000)
declare @sql3 varchar(8000)

set @sql1='...'
set @sql2='...'
set @sql3='...'

exec (@sql1+@sql2+@sql3)

这样拆分就不通用了
