如果是在PostgreSQL中，在名字周围使用双引号，比如:

select "from" from "table";

注意:PostgreSQL内部自动将所有不带引号的命令和参数转换为小写。命令和标识符不区分大小写。sEleCt * from tAblE;解释为select * from table;。然而，双引号内的参数是原样使用的，因此是区分大小写的:select * from "table";and select * from "Table";从两个不同的表获取结果。

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?')

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;

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。

我也遇到过这个问题。 解决方案是在查询中像这样放入[Column_Name]。

string query= "Select [Name],[Email] from Person";

所以它会工作得很好。

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]
