ORACLE SELECT ... FOR UPDATE OF 列级锁定写法 迁移 kingbasees V8 oracle 模式 怎么改

兼容性判定

怎么改

需按命中位置逐条评估改写

判定说明

能力矩阵暂未声明该特征，按未覆盖处理并降低置信度，建议 PoC 复核

库侧 / 应用侧路径

推荐路线：case_by_case。验证建议：Oracle 的 OF 接"列名"（锁定该列所在表的行）；PG 系 FOR UPDATE OF 接"表别名"——语法迁移必须把列改成表引用，多表连接场景锁范围需重审

规则样例

SELECT e.sal FROM emp e, dept d WHERE e.dept_id = d.id FOR UPDATE OF e.sal

SELECT * FROM acct WHERE id = 1 FOR UPDATE OF balance NOWAIT

SELECT * FROM acct WHERE id = 1 FOR UPDATE
