调用示例

GO

DECLARE    @return_value int,
        @recordTotal int

EXEC    @return_value = [dbo].[P_GridViewPager]
        @recordTotal = @recordTotal OUTPUT,
        @viewName = N'Study_StudentStatistics',
        @fieldName = N'termcourseid,loginname',
        @keyName = N'id',
        @pageSize = 200,
        @pageNo = 1,
        @orderString = N'id'

SELECT    @recordTotal as N'@recordTotal'

SELECT    'Return Value' = @return_value

GO
