sql - 在 SQLite 中转义表名？

Question

我在 SQLite 中有一个名为 References 的表，所以我似乎无法定位它。我用来编辑数据库的 SQLite Studio 抛出错误。

有没有办法转义数据库名称？

查询是:

UPDATE References 
SET DateTimeLastEdited = datetime('now', 'localtime')
WHERE NewsItemID = old.NewsItemID;

(这是我正在制作的触发器的一部分。)

您可以使用双引号对表名进行转义:

UPDATE "References" SET DateTimeLastEdited = datetime('now', 'localtime') WHERE NewsItemID = old.NewsItemID;

根据要转义的内容，需要使用不同的分隔符:

If you want to use a keyword as a name, you need to quote it. Thereare four ways of quoting keywords in SQLite:

'keyword' A keyword in single quotes is a string literal.

"keyword" A keyword in double-quotes is an identifier.

[keyword] Akeyword enclosed in square brackets is an identifier. This is notstandard SQL. This quoting mechanism is used by MS Access and SQLServer and is included in SQLite for compatibility.

`keyword` Akeyword enclosed in grave accents (ASCII code 96) is an identifier.This is not standard SQL. This quoting mechanism is used by MySQL andis included in SQLite for compatibility.
