mySQL查询选择列，其中value = a或value = b等

Question

如何编写mysql查询，以便我可以在列下选择等于resultA或resultB或resultC等的条目。

类似的东西：

SELECT * FROM myTable WHERE myColumn = resultA OR WHERE myColumn = resultB OR WHERE myColumn = resultC...

Answer 1

SELECT *
FROM myTable
WHERE myColumn = 'resultA' 
   OR myColumn = 'resultB' 
   OR myColumn = 'resultC';

可替换地，

SELECT *
FROM myTable
WHERE myColumn IN ('resultA', 'resultB', 'resultC');

Answer 2

多次使用WHERE，只需在条件之间使用OR

SELECT * 
FROM myTable 
WHERE myColumn = 'resultA'
OR myColumn = 'resultB'
OR myColumn = 'resultC'

请注意，我将resultX用单引号包围，假设它们是字符串，如果它们是整数，则可以省略它们

Answer 3

这应该有用。

SELECT * FROM myTable WHERE myColumn = 'resultA' OR myColumn = 'resultB' OR myColumn = 'resultC'

Answer 4

SELECT * FROM myTable WHERE myColumn in (resultA, resultB, resultC ....)
