Java 如何通过postgresql查询在字符串列表中搜索枚举?
考虑一个SQL语句:Java 如何通过postgresql查询在字符串列表中搜索枚举?,java,postgresql,enums,sql-in,Java,Postgresql,Enums,Sql In,考虑一个SQL语句: select * from table where status in <statuses> handle.createQuery("select * from table where status in <statuses>") .bindList("statuses", statuses) .map(Mapper.instance)
select * from table where status in <statuses>
handle.createQuery("select * from table where status in <statuses>")
.bindList("statuses", statuses)
.map(Mapper.instance)
.list());
在Java中,我有一个字符串表示的枚举列表:
List<String> list = new ArrayList<>();
list.add("enum1");
list.add("enum2");
我尝试用CAST(enum1作为statusType)或enum1::statusType包装每个列表项,但没有成功
非常感谢您的帮助。您可以将枚举转换为文本
handle.createQuery("select * from table where status::text in <statuses>")
.bindList("statuses", statuses)
.map(Mapper.instance)
.list());
handle.createQuery(“从status::text所在的表中选择*)
.bindList(“状态”,状态)
.map(Mapper.instance)
.list());
您是否尝试过此select*from table where status::text in
org.jdbi.v3.core.statement.UnableToExecuteStatementException: org.postgresql.util.PSQLException: ERROR: operator does not exist: status = character varying
Hint: No operator matches the given name and argument types. You might need to add explicit type casts.
handle.createQuery("select * from table where status::text in <statuses>")
.bindList("statuses", statuses)
.map(Mapper.instance)
.list());
