简化SQL查询以查看列表

Question

我有一个像

这样的查询

SELECT * FROM table WHERE Filename = "abc.exe" OR Filename = "test.txt" OR Filename = "def.exe" .... OR

有没有办法将其简化为'更清洁'，我可以说WHERE Filename = ("abc.exe", "test.txt", "def.exe", ...)

Answer 1

使用IN运算符而不是多个OR条件。使用=，您无法比较多个值

where Filename in ("abc.exe","test.txt","def.exe",..)

Answer 2

是的，你可以使用IN子句，它检查一个值是否是指定候选者之一。

示例：

WHERE Filename IN ("abc.exe","test.txt","def.exe")
