jooq：将时间间隔添加到时间戳 postgres

Question

我正在尝试将 timestamptz 值进一步增加到未来的间隔秒数。有没有一种方法可以按摩这些类型，以便 jooq 允许我在一个语句中这样做，或者我只需要获取 TriggerRecord 并在 Java 代码中进行计算？

代码和尝试如下：

public final TableField<TriggerRecord, Instant> PAUSED_UNTIL = createField(DSL.name("paused_until"), SQLDataType.TIMESTAMPWITHTIMEZONE(6), this, "", new OffsetDateTimeInstantConverter());

public class OffsetDateTimeInstantConverter implements Converter<OffsetDateTime, Instant> {
    private static Instant min;

    public OffsetDateTimeInstantConverter() {
    }

    public Instant from(OffsetDateTime databaseObject) {
        return databaseObject == null ? null : databaseObject.toInstant();
    }

    public OffsetDateTime to(Instant userObject) {
        if (userObject == null) {
            return null;
        } else {
            return userObject.isBefore(min) ? OffsetDateTime.MIN : userObject.atOffset(ZoneOffset.UTC);
        }
    }

    public Class<OffsetDateTime> fromType() {
        return OffsetDateTime.class;
    }

    public Class<Instant> toType() {
        return Instant.class;
    }

    static {
        min = OffsetDateTime.MIN.toInstant();
    }

在一种情况下会出错

final Long ps = 360;
query = using(configuration)
                .update(TRIGGER)
                .set(TRIGGER.ACTIVE, active)
                .set(TRIGGER.PAUSED_UNTIL,
                     TRIGGER.PAUSED_UNTIL.add(ps))
                .returning()
                .fetch();
ERROR: operator does not exist: timestamp with time zone + timestamp with time zone

并且在另一次尝试中出现错误

        final var query = using(configuration)
                .update(TRIGGER)
                .set(TRIGGER.ACTIVE, active)
                .set(TRIGGER.PAUSED_UNTIL,
                     TRIGGER.PAUSED_UNTIL
                     .add(val(DayToSecond.valueOf(Duration.ofSeconds(ps)))))
org.jooq.exception.DataTypeException: Cannot convert from +0 00:06:00.000000000 (class org.jooq.types.DayToSecond) to class java.time.OffsetDateTime

update trigger set "paused_until" = ("alert"."trigger"."paused_until" + cast(? as timestamp(6) with time zone))

Answer 1

对于这个特定的表达式，这看起来像 bug #12036, which has been fixed in jOOQ 3.17.0, 3.16.4, and 3.15.8. The workaround is to use plain SQL templating。

DSL.field("{0} + {1}", 
    TRIGGER.PAUSED_UNTIL.getDataType(),
    TRIGGER.PAUSED_UNTIL, ps
);
