在FoxPro 2.6中,投管处有办法在选修局指挥中使用一个变量? 例如,我如何撰写以下问询:
SELECT * FROM DBFILE WHERE Ord_no = temp_no
鉴于“速度”不是以前确定的变量。 我尝试使用“&temp_no”,但这似乎不是正确的辛迪加。
你的法典是正确的,你没有必要通过“和”加以宏观。 可能失败的是数据类型。 如果您的表格“dbfile”,“ord_no”一栏是数字,而你的变数“temp_no”是特征说明,那将因数据类型不匹配而失败。 REGARDLESS使用“&”宏观数据。
MyVarOrd_No=23
* 选自家庭部,Ord_No=MyVarOrd
或如果一个星号/星号一栏仅作改动
MyVarOrd_No = "23"
However you may need to pad with spaces/justify if its being picky.
