在安卓SQLite中使用单引号

Question

我正在从Web服务中获取值。我的一些值带有单引号。像这个示例的sqlite不支持单引号。所以我用双引号替换它们。然后当我从数据库中检索该值时，我无法解析该值。我得到了“解析器异常未格式化”的错误消息。有人能告诉我如何解决吗？

这是我将单引号替换为双引号的代码

              stockservicevalue=stockservicevalue.replaceAll("'", "\"");

这是我从数据库检索值的方式

String sql = "SELECT * FROM MyQuest;";

Answer 2

我们可以使用Android的DatabaseUtils类。

stockservicevalue = DatabaseUtils.sqlEscapeString(stockservicevalue);

Answer 4

如何在SQLite Java中插入单引号。这对我起作用。

String str = "'Hello";

str = str.replace("'","\\'");
