Winforms Datagrid，显示外键

Question

Currently I have a DataGrid, and a datasource. 目前，我有一个DataGrid和一个数据源。

The Datasource is directly pulled from the database in this order: 数据源按以下顺序直接从数据库中提取：

Id, SalaryId, Old, New ID，SalaryId，旧，新

Problem is that it displays the SalaryId, I want it to display the SalaryId Value 问题是它显示SalaryId，我希望它显示SalaryId值

How do I do this? 我该怎么做呢？

Pure guess here, but you probably just need to rewrite your original SQL query from something like: 纯粹在这里猜测，但是您可能只需要从类似以下内容的地方重写您的原始SQL查询：

SELECT ID, SALARYID, OLD, NEW FROM tblEMPLOYEE

to something like: 像这样：

SELECT a.ID, b.SALARYVALUE, a.OLD, a.NEW FROM tblEMPLOYEE a, tblSALARY b
WHERE a.SALARYID = b.ID
