在GetRecordFromPage（铁拳,[e-mail])的基础上增加rowcount

1、增加声明 @rowTotal  int output

2、实现下面方法

declare @strRowSQL nvarchar(4000)

if @strWhere != ''
set @strRowSQL = 'select @RowTotal=count(*) from ['
 + @tblName + '] where ' +  @strWhere
else 
set @strRowSQL = 'select @RowTotal=count(*) from ['
 + @tblName + '] '

EXEC sp_executesql @strRowSQL,N'@RowTotal INT OUT',@RowTotal OUT
