c# - 如何在 C# 中延迟加载 DataGridView

Question

我想从 sql server 中检索大数据。我希望它逐行加载并显示到 DataGridView 中。就像我在 Sql server management studio 2005 中执行 Sql Script 一样。我该怎么做？!

Answer 1

使用此查询进行分页

DECLARE @PageIndex int=1
DECLARE @PageSize int=10
DECLARE @StartRow int
DECLARE @EndRow int


SET @StartRow = (@PageSize * (@PageIndex - 1))  + 1  
SET @EndRow = @PageSize * @PageIndex + 1

SET NOCOUNT ON;

WITH ArticleSearch AS
(
    SELECT
       ROW_NUMBER() OVER 
         (
            -- Dynamic sorting
            ORDER BY       tablename.fieldname 


          ) AS RowNumber,   *


     FROM            tablename

)

-- Statement that executes the CTE
SELECT *
FROM
      ArticleSearch a
WHERE
      a.RowNumber BETWEEN @StartRow AND @EndRow - 1
ORDER BY
      a.RowNumber 

您可以将 pageindex 作为参数传递，以获取要显示的页面和每个页面中总记录的 pagesize
