DELETE .. ORDER BY .. LIMIT

适用于 ✅ 开源版 ✅ 专业版 ✅ 企业版

ORDER BY 和 LIMIT 子句允许仅删除表中数据的子集，基于它们的排序。这对于实现队列语义很有用，例如仅删除最顶行，并可能返回它一次完成。

方言支持

此示例使用 jOOQ

deleteFrom(BOOK).orderBy(BOOK.ID.asc()).limit(1)

翻译成以下特定方言的表达式

DELETE FROM BOOK
ORDER BY BOOK.ID ASC
LIMIT 1

DELETE FROM BOOK
WHERE BOOK.ID IN (
  SELECT BOOK.ID
  FROM BOOK
  ORDER BY BOOK.ID ASC
  LIMIT 1
)

DELETE FROM BOOK
WHERE ID IN (
  SELECT BOOK.ID
  FROM BOOK
  ORDER BY BOOK.ID ASC
  LIMIT 1
)

DELETE FROM BOOK
WHERE BOOK.ID IN (
  SELECT BOOK.ID
  FROM BOOK
  ORDER BY BOOK.ID ASC
  FETCH NEXT 1 ROWS ONLY
)

DELETE FROM BOOK
ORDER BY BOOK.ID ASC
ROWS 1

DELETE FROM BOOK
WHERE BOOK.ID IN (
  SELECT *
  FROM (
    SELECT FIRST 1 BOOK.ID
    FROM BOOK
    ORDER BY BOOK.ID ASC
  ) x
)

DELETE FROM BOOK
WHERE BOOK.ID IN (
  SELECT *
  FROM (
    SELECT BOOK.ID
    FROM BOOK
    ORDER BY BOOK.ID ASC
    LIMIT 1
  ) t
)

DELETE FROM BOOK
WHERE BOOK.ID IN (
  SELECT TOP 1 BOOK.ID
  FROM BOOK
  ORDER BY BOOK.ID ASC
)

DELETE FROM BOOK
WHERE BOOK.ID IN (
  SELECT *
  FROM (
    SELECT TOP 1 BOOK.ID
    FROM BOOK
    ORDER BY BOOK.ID ASC
  ) x
)

/* UNSUPPORTED */
