You''re using two different SELECT queries, but not joinging them together.I HIGHLY suggest you read up on and practice some SQL JOIN queries. The DGV cannot display data side-by-side from seperate queries. They MUST be JOIN''d to generate a single datatable or dataview containing all the data you wish to display. 这篇关于3表显示到DataGridView的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
