jdbc/PreparedStatement转义序列

我试图在Java中通过PreparedStatement调用SQL时实现jdbc转义序列

下面是我的示例代码

String sql ="select 1 from dual where  'abcd' = ? {escape '|'}";
ps = con.prepareStatement(sql);
ps.setString(1,"abcd");
ps.executeQuery();

在执行该类时，我得到以下错误

java.sql.SQLSyntaxErrorException:ORA-00933:sql命令未正确结束

有人能帮忙吗？

这只对LIKE子句有效

请尝试以下操作：

String sql = "select 1 from dual where 'abcd' like ? {escape '|'}";

不能将转义序列与IN子句一起使用？@Gopal:不。只能与LIKE子句一起使用。为什么要将它与IN子句一起使用？我有许多sql文件，其中有IN子句将接受可变数量的参数。我想到了转义单引号，并将一个字符串从Java传递到sql。类似于ps.setString1、abc |'、| bcd |'；并将| pipe符号转义。@Gopal这怎么行呢，别以为你能发明数据库所没有的功能。
