MYSQL 显式分区选择（FROM t PARTITION (p)） 迁移 highgo 4.5 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：PG 声明式分区无 PARTITION (p) 语法，需改直查分区子表或改写为分区键条件；OB 支持该语法

规则样例

SELECT * FROM sales PARTITION (p2024) WHERE amt > 0

DELETE FROM log_t PARTITION (p_old)

SELECT * FROM sales WHERE sale_date >= DATE '2024-01-01'
