SQLite：接近“假”：语法错误...如何解决单引号抛出错误

Question

我在自定义构建的 ionic andorid 插件中使用 capacitor-community sqlite 和 在执行execute 查询时抛出类似near "false": syntax error 的错误，其中表列类型 是varchar。

这里是查询：

insert or replace into FormSchema (SchemaId,SchemaName,Schema,Parent,Application,ModifiedDateTime,Version,PageType,favorite,CategoryType,IsDeleted)

在 sqlite db 浏览器中也一样

用于 SQLite 错误消息的 DB 浏览器：

即使我添加了单斜杠和双斜杠，例如 .... where (favorites.favorite= \'false\ 和 .... where (favorites.favorite= \\'false\\，但它不起作用。

我需要在查询中做哪些修改。如何解决上述错误？

谢谢。

Answer 1

看起来'false' 是字符串文字的一部分，或者至少第一个' 终止了字符串文字。

使用'' 转义字符串文字中的单引号，例如''false''。

更好的是，使用 sql 变量并绑定文字值，这样您就不必处理字符串转义了。
