[英]Java Named Query
I'm trying to create a Java named query which does the following postgres query: 我正在尝试创建一个Java命名查询,它执行以下postgres查询:
select * from call_attempt where result is NULL and id like '0000000101%';
The 0000000101 is set to id in my code, so this is what I want to do, but it's malformed: (I'm not sure how to set the id field while using the % and it has to be inside ' ') 0000000101在我的代码中被设置为id,所以这就是我想要做的,但它的格式不正确:(我不确定如何在使用%时设置id字段,它必须在''内)
@NamedQuery(name = AttemptEntity.JQL.NOTENDED,
query = "SELECT ae FROM AttemptEntity ae WHERE ae.result IS NULL,"
+ " ae.correlationId LIKE '=:id%'")
First, you forgot the and
, and replaced it by a comma. 首先,你忘记了
and
,并用逗号替换它。
Second, the %
must be passed as part of the argument: 其次,
%
必须作为参数的一部分传递:
SELECT ae FROM AttemptEntity ae WHERE ae.result IS NULL
and ae.correlationId LIKE :id
And then, when executing the query: 然后,在执行查询时:
String id = "0000000101%";
query.setParameter("id", id);
You can't have the % in the NamedQuery, but you can have it in the value you assign the parameter. 您不能在NamedQuery中拥有%,但您可以在分配参数的值中使用它。
query.setParamter("id", 0000000101+ "%");
You also need to add AND and remove the comma after NULL. 您还需要添加AND并在NULL后删除逗号。
Reference: Named Query with like in where clause 参考: 在where子句中使用like的命名查询
