查询表里符合特定搜索条件的数据
|
|
====================================
|
|
|
|
|
|
|
|
当要查询满足特定搜索条件的数据时，给 SELECT 查询语句增加一个 WHERE 子句即可。SQL 语句格式如下：
|
|
|
|
```javascript
|
|
SELECT select_list FROM table_list
|
|
WHERE query_condition
|
|
```
|
|
|
|
|
|
|
|
以"在 ODC 中运行查询"页面的图为例，查询 2 号仓库第 5 区的订单，SQL 语句如下：
|
|
|
|
```javascript
|
|
SELECT * FROM ordr WHERE o_w_id=2 and o_d_id=5 ;
|
|
```
|
|
|
|
|
|
|
|
在 ODC 中的查询结果如下图所示：

执行结果如下：
|
|
|
|
```unknow
