+-- ==============================================================================
+-- RailwaySystem 数据库迁移脚本: 001_sys_oper_log_cost_time.sql
+-- 适用数据库: KingbaseES V009R003C018 (schema: public)
+-- 执行目标: 为系统操作日志表 sys_oper_log 补齐缺失的 cost_time 字段
+-- 字段对齐: Java SysOperLog.costTime (Long) -> BIGINT DEFAULT 0
+-- 幂等机制: ADD COLUMN IF NOT EXISTS 语法级存在性保护
+-- 数据安全: 零清空、零删表，保留全部历史数据，旧数据默认赋 0
+-- ==============================================================================
+
+-- 1. 显式添加 cost_time 字段（若不存在），设置默认值为 0
+ALTER TABLE public.sys_oper_log ADD COLUMN IF NOT EXISTS cost_time BIGINT DEFAULT 0;
+
+-- 2. 设置列注释
+COMMENT ON COLUMN public.sys_oper_log.cost_time IS '消耗时间';
+
+-- 3. 对已有存量数据（若为 NULL）补偿初始化为 0
+UPDATE public.sys_oper_log SET cost_time = 0 WHERE cost_time IS NULL;
