我希望有2个表SalesOrderHeader和SalesOrderLine具有一对多的关系,并且还想构建索引。
SalesOrderHeader表:
SalesOrderNumber
------------------
| |
| 1 |
| |
|----------------|
| |
| |
| 2 |
| |
| |
------------------
SalesOrderLine表:
SalesOrderNumber Line
-------------------------
| | 1 |
| 1 |------|
| | 2 |
|----------------|------|
| | 1 |
| |------|
| 2 | 2 |
| |------|
| | 3 |
-------------------------
请告知如何使用这些表结构方法构建关联关系和索引?

创建外键
CREATE NONCLUSTERED INDEX IX_SalesOrderNumberLine_SalesOrderNumberID
ON dbo.SalesOrderNumberLine(SalesOrderNumberID);
然后在该列上创建非聚集索引
