ORACLE 视图 WITH CHECK OPTION（含命名 CONSTRAINT） 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：源工具三段式处理：目标 OB<4.2.5.7 整体移除；join 视图上的 CHECK OPTION 一律移除 （verified unsupported）；"WITH CHECK OPTION CONSTRAINT " 保留 CHECK OPTION、 仅去掉命名 CONSTRAINT 子句。移除即放弃写入校验语义，需在报告中显式标注

规则样例

CREATE VIEW v_hi AS SELECT * FROM emp WHERE sal > 1000 WITH CHECK OPTION

CREATE VIEW v_hi AS SELECT * FROM emp WHERE sal > 1000 WITH CHECK OPTION CONSTRAINT v_hi_chk

CREATE VIEW v_hi AS SELECT * FROM emp WHERE sal > 1000
