任何（数组）比较都不起作用

Question

我有一个table1（id - unique）

public class TimeoutInterceptor implements HttpRequestInterceptor {

private int requestTimeout = 1 * DateTimeConstants.MILLIS_PER_MINUTE;

private ScheduledExecutorService executorService = Executors.newSingleThreadScheduledExecutor();

public TimeoutInterceptor() {  }

public TimeoutInterceptor(final int requestTimeout) {
    this.requestTimeout = requestTimeout;
}

@Override
public void process(final HttpRequest request, final HttpContext context) throws HttpException, IOException {
    if (request instanceof AbstractExecutionAwareRequest) {
        final AbstractExecutionAwareRequest abortableRequest = (AbstractExecutionAwareRequest) request;
        setAbort(abortableRequest);
    } else if (request instanceof HttpRequestWrapper) {
        HttpRequestWrapper wrapper = (HttpRequestWrapper) request;
        this.process(wrapper.getOriginal(), context);
    }

}

/**
 * @param abortableRequest
 */
private void setAbort(final AbstractExecutionAwareRequest abortableRequest) {
    final SoftReference<AbstractExecutionAwareRequest> requestRef = new SoftReference<AbstractExecutionAwareRequest>(abortableRequest);

    executorService.schedule(new Runnable() {

        @Override
        public void run() {
            AbstractExecutionAwareRequest actual = requestRef.get();
            if (actual != null && !actual.isAborted()) {
                actual.abort();
            }
        }
    }, requestTimeout, TimeUnit.MILLISECONDS);

}

public void setRequestTimeout(final int requestTimeout) {
    this.requestTimeout = requestTimeout;
}
}

和table2

|---|----------|
|id | array    |
|---|----------|
|0  | [2, 4, 6]|
|1  | [3, 5, 1]|
|---|----------|

我现在不知道如何提出这样的请求：

|---|----|
|id |val |
|---|----|
|1  | 23 |
|2  | 34 |
|3  | 19 |
|4  | 61 |
|5  | 47 |
|6  | 3  |
|---|----|

修改

或者更简单，这不起作用：

 SELECT val FROM table2 WHERE id = ANY(SELECT array FROM table1 WHERE id = 1)

虽然这有效：

select 2 = any (select array[2, 4]);
ERROR:  operator does not exist: integer = integer[]
LINE 1: select 2 = any (select array[2, 4]);
                 ^
HINT:  No operator matches the given name and argument type(s). You might need to add explicit type casts.

Answer 1

1）

Regex r = new Regex("src=\"(?<src>[^\"]+)\"")

2）

SELECT val FROM table2
WHERE id = ANY((SELECT array FROM table1 WHERE id = 1)::int[])

3）

SELECT val FROM table2 
WHERE ARRAY[id] <@ (SELECT array FROM table1 WHERE id = 1)

4）

SELECT val FROM table2
WHERE id in (SELECT unnest(array) FROM table1 WHERE id = 1)

5）正如你所看到的，有很多可能性;）
