主题:[讨论]一个通用分页存储过程的用法(回帖给分)
这是我从网上搜到的一个通用分页存储过程,经过调试语法检查通过.
CREATE PROCEDURE pagination3
@tblName varchar(255), -- 表名
@strGetFields varchar(1000)="*", -- 需要返回的列
@fldName varchar(255)="", -- 排序的字段名
@PageSize int = 10, -- 页尺寸
@PageIndex int = 1, -- 页码
@doCount int = 0, -- 返回记录总数, 非 0 值则返回
@OrderType int = 0, -- 设置排序类型, 非 0 值则降序
@strWhere varchar(1500) = "" -- 查询条件 (注意: 不要加 where)
AS
declare @strSQL varchar(5000) -- 主语句
declare @strTmp varchar(110) -- 临时变量
declare @strOrder varchar(400) -- 排序类型
if @doCount != 0
begin
if @strWhere !=""
set @strSQL = "select @out1=count(*) as Total from [" + @tblName + "] where "+@strWhere
else
set @strSQL = "select @out1=count(*) as Total from [" + @tblName + "]"
end
--以上代码的意思是如果@doCount传递过来的不是0,就执行总数统计。以下的所有代码都是@doCount为0的情况:
else
begin
if @OrderType != 0
begin
set @strTmp = "<(select min"
set @strOrder = " order by [" + @fldName +"] desc"
--如果@OrderType不是0,就执行降序,这句很重要!
end
else
begin
set @strTmp = ">(select max"
set @strOrder = " order by [" + @fldName +"] asc"
end
if @PageIndex = 1
begin
if @strWhere != ""
set @strSQL = "select top " + str(@PageSize) +" "+@strGetFields+ "
from [" + @tblName + "] where " + @strWhere + " " + @strOrder
else
set @strSQL = "select top " + str(@PageSize) +" "+@strGetFields+ "
from ["+ @tblName + "] "+ @strOrder
--如果是第一页就执行以上代码,这样会加快执行速度
end
else
begin
--以下代码赋予了@strSQL以真正执行的SQL代码
set @strSQL = "select top " + str(@PageSize) +" "+@strGetFields+ " from ["+ @tblName + "] where [" + @fldName + "]" + @strTmp + "(["+ @fldName + "]) from (select top " + str((@PageIndex-1)*@PageSize) + " ["+ @fldName + "] from [" + @tblName + "]" + @strOrder + ") as tblTmp)"+ @strOrder
if @strWhere != ""
set @strSQL = "select top " + str(@PageSize) +" "+@strGetFields+ " from ["+ @tblName + "] where [" + @fldName + "]" + @strTmp + "(["+ @fldName + "]) from (select top " + str((@PageIndex-1)*@PageSize) + " ["+ @fldName + "] from [" + @tblName + "] where " + @strWhere + " "+ @strOrder + ") as tblTmp) and " + @strWhere + " " + @strOrder
end
end
--exec (@strSQL)
set @strSQL = " select * from Role_Function "
exec(@strSQL)
GO
问题:在JSP中调用此存储过程,显示一个表的内容,使用
String sql = "{ call dbo.pagination3( ?, ?, ?, ?, ?, ?, ?, ? ) }";
cstmt = conn.prepareCall( sql );
cstmt.setString( 1, TabName );
cstmt.setString( 2, Field );
cstmt.setString( 3, null );
cstmt.setInt( 4, PageSize );
cstmt.setInt( 5, ShowPage );
cstmt.setInt( 6, 0 );
cstmt.setInt( 7, 0 );
cstmt.setString( 8, null );
rs = cstmt.execute();
可是结果却是:
An error occurred at line: 19 in the jsp file: /test1.jsp
Generated servlet error:
Type mismatch: cannot convert from boolean to ResultSet
请问:怎么才能将存储过程中的结果显示出来?
