速览

25P01 表示操作需要活动 SQL 事务。选定案例在自动提交会话中发送 SAVEPOINT,得到精确错误且会话保持 IDLE;随后在 BEGIN 内重新执行并提交。

含义

源码把语句名填入 %s can only be used in transaction blocks;本文的 SAVEPOINT 路径严重级别为 ERROR。同一 SQLSTATE 还覆盖 COMMIT AND CHAIN/ROLLBACK AND CHAIN 的错误,以及无事务时 COMMIT/ROLLBACK 的警告,固定报文是 there is no transaction in progress

诊断

执行 SAVEPOINT、RELEASE SAVEPOINT 或 ROLLBACK TO SAVEPOINT 前,先确认客户端已进入显式事务块。选定运行中失败的自动提交语句后仍为 IDLE;修复序列是 BEGINSAVEPOINTRELEASECOMMIT

处理

创建保存点前先启动显式事务。若操作误发在事务块外,应修正客户端事务包装后重试;本自动提交错误没有遗留失败事务块,因此不需要回滚。

可复现案例

在一次性实例上执行过的场景。其中 1 个附有可执行 SQL,正文相应小节里给出。

savepoint_without_transaction PG 10 / 18 有 SQL

前置条件

  • A runner-owned disposable target is provisioned.

触发

Run SAVEPOINT without BEGIN, then repeat inside an explicit block.

断言

  • SQLSTATE is 25P01
  • SAVEPOINT outside a block reports the no-active-transaction message
  • An explicit BEGIN/SAVEPOINT/RELEASE/COMMIT repair succeeds

处置

Follow the explicit transaction or source boundary described by the case.

清理

Drop the case schema with an owner connection.

源码报文

xact.c%s can only be used in transaction blocks 组装语句级报文;本案例把 %s 替换为 SAVEPOINT,严重级别为 ERRORCOMMIT AND CHAINROLLBACK AND CHAIN 在无事务块时使用同一动态形式;无事务时的 COMMIT/ROLLBACK 则使用 WARNING 报文 there is no transaction in progress

报文模板

源码里的格式串,不是某一次运行的输出。%s 之类是占位符,实际报文会填入对象名与取值。适用范围一栏是核验时留下的原始英文记录,未经翻译。

主消息 %s can only be used in transaction blocks

来源:src/backend/access/transam/xact.c @ REL_18_6

适用范围:The %s substitution is the statement name; the selected message is SAVEPOINT can only be used in transaction blocks.

主消息 there is no transaction in progress

来源:src/backend/access/transam/xact.c @ REL_18_6

适用范围:Used by no-transaction COMMIT/ROLLBACK branches; it is not the selected SAVEPOINT ERROR.

断言

每条断言都写明了是怎么核实的,以及它不覆盖什么。这一层是核验时留下的原始英文记录,照原样呈现,未经翻译。

  • 25P01 is no_active_sql_transaction in Class 25.

    核实方式Read the fixed condition row and macro.

    不覆盖It is distinct from the branch-transaction condition 25005.

    来源src/backend/utils/errcodes.txt

  • The fixed xact.c paths report 25P01 when SAVEPOINT, RELEASE SAVEPOINT, or ROLLBACK TO SAVEPOINT is issued without an explicit transaction block; the selected SAVEPOINT path is ERROR.

    核实方式Trace the SAVEPOINT state branch and compare the official savepoint boundary.

    不覆盖Other no-active paths may be WARNING or use a different statement name; this case uses the SAVEPOINT ERROR path.

    来源src/backend/access/transam/xact.c · doc/src/sgml/ref/savepoint.sgml · raw/calls/REL_18_6.jsonl

  • The selected SAVEPOINT case returned 25P01 on PostgreSQL 18.6 and 10.21, stayed IDLE in autocommit mode, and completed the explicit-block repair.

    核实方式Read the selected summaries and structured diagnostics.

    不覆盖The case covers SAVEPOINT outside a transaction block, not every warning or no-active path.

  • The fixed xact.c source also uses 25P01 for no-transaction COMMIT/ROLLBACK warnings with "there is no transaction in progress", while COMMIT AND CHAIN and ROLLBACK AND CHAIN use the transaction-block error form.

    核实方式Read the resolved report groups at the no-transaction COMMIT/ROLLBACK and transaction-chain branches.

    不覆盖These warning/error paths are source-backed context, not the selected SAVEPOINT runtime case.
