简单的解决方案

假设列名是from;因此，查询中的列名可以通过表别名引用

Select * from user u where u.from="US"

我在尝试更新名称为关键字的列时遇到了同样的问题。上面的解决方案对我没有帮助。我通过简单地指定表的名称来解决它，就像这样:

UPDATE `survey`
SET survey.values='yes,no'
WHERE (question='Did you agree?')

在Apache Drill中，使用反引号:

select `from` from table;

将列名像这样用括号括起来，from变成[from]。

select [from] from table;

也可以使用以下命令(在查询多个表时很有用):

select table.[from] from table;

如果您正在使用SQL Server，您可以简单地将方括号括在列名或表名周围。

select [select]
from [table]

一些可靠的答案——但投票最多的答案是狭隘的，只涉及SQL Server。总而言之:

If you have source control, the best solution is to stick to the rules, and avoid using reserved words. This list has been around for ages, and covers most of the peculiarities. One tip is that reserved words are rarely plural—so you're usually safe using plural names. Exceptions are DIAGNOSTICS, SCHEMAS, OCTETS, OFFSETS, OPTIONS, VALUES, PARAMETERS, PRIVILEGES and also verb-like words that also appear plural: OVERLAPS, READS, RETURNS, TRANSFORMS. Many of us don't have the luxury of changing the field names. There, you'll need to know the details of the RDBM you're accessing: For SQL Server use [square_braces] around the name. This works in an ODBC connection too. For MySQL use `back_ticks`. Postgres, Oracle and several other RDBMs will apparently allow "double_quotes" to be used.

在表名上加上冒犯性的单词也可以。
