AHK 脚本一旦开始保存账号配置、任务记录、历史数据或者几万行以上的结构化内容，继续靠 ini、txt 和零散 CSV 文件维护，很快就会遇到查询慢、更新麻烦、并发写入难处理的问题。我整理这套 CSQLite，就是为了让 AHK v1 能直接使用 SQLite，把数据放进一个本地数据库文件里管理。
这份资源面向 AutoHotkey v1，核心是对 sqlite3.dll 的一层类封装。常用的打开数据库、执行 SQL、返回结果表、事务写入、错误信息、影响行数和最后插入 ID 都已经整理成比较顺手的接口，新手不用从 SQLite C API 的指针和回调开始啃。
它适合解决什么问题
- 给桌面工具保存配置、用户数据和操作历史；
- 给采集脚本、自动办公脚本建立本地数据表；
- 按条件查询、排序、统计和批量更新数据；
- 使用事务一次写入多条记录，避免写到一半留下不完整数据；
- 用 REGEXP 和 regex_replace 在 SQL 中完成正则筛选与替换。
常用入口怎么理解
OpenDB() 负责打开或创建数据库，Exec() 适合 CREATE、INSERT、UPDATE、DELETE 这类不需要结果表的 SQL，GetTable() 则把 SELECT 结果整理成列名和行数组。执行失败后可以读取 ErrorCode 和 ErrorMsg，排查时不用只看到一个“数据库打不开”。
Changes() 返回最近一次操作影响的行数，TotalChanges() 是当前连接累计变化量，LastInsertRowID() 可取得自增主键。数据库可能被其他程序短暂占用时，可以先用 SetTimeout() 设置等待时间。
依赖和使用边界
下载包需要放入与 AHK 位数匹配的 sqlite3.dll，32 位 AHK 配 32 位 DLL，64 位 AHK 配 64 位 DLL。当前封装要求 SQLite 版本不低于 3.29。SQLite 很适合单机工具和中小型本地数据，但它不是远程多人数据库；需要跨电脑协同或高并发服务时，应该换成专门的数据库服务。
SQL 中拼接外部输入时还要注意引号和注入问题。正式项目更建议使用参数绑定或先严格校验数据，不要把用户输入原样接到 SQL 后面。
我建议的入门顺序
先运行下面的完整示例，确认 DLL 能加载、数据库能建立，再依次看建表、事务插入、GetTable 查询和 UPDATE。示例会在脚本目录创建 test.db，并重建 ahk_demo 测试表，不要直接改成重要数据库路径运行。

#Requires AutoHotkey v1.1
; 示例内容包括：
;
; 加载 sqlite3.dll
; 打开 test.db
; 创建/重建 ahk_demo 表
; 事务插入多行数据
; 查询全部数据
; 使用自定义 REGEXP
; 使用自定义 regex_replace
; UPDATE
; Changes() / TotalChanges() / LastInsertRowID()
; 最后 MsgBox 显示结果
