推荐答案

您只需要编写一个结合两个表格数据的查询，并将其显示为网格的数据源。



还有其他wya要返回在前端分别打破两个表然后合并 - 但我不建议这样做，因为在DB级别将它们组合起来要容易得多。



样本：

You just need to write a query that combines the data of two table tables and show it as datasource of your grid.

There is other wya to retrieve both tables separately on front end and then combine - but I would not suggest this as it would be much easier to combine them at DB level.

Sample:

SELECT 
   t1.col1, t1.col2, t2.col3
FROM 
   table1 t1
INNER JOIN
   table2 t2
ON t1.RegNO = t2.RegNO

结果集将具有可直接设置为网格源的组合数据。

Result set would have combined data that can directly be set as source for grid.
