本插件主要是支持在UE蓝图中连接和操作MYSQL数据库。
1. 数据库连接 【 Connect MySql 】
输入：
Host：数据库IP地址
Port: 数据库开放端口
User: 数据库用户名
Password：数据库密码
DBName：指定连接的数据库库名
输出：
Success：返回数据库是否连接成功
Error No: 连接错误返回错误编号，成功返回0
Error Msg：连接错误返回错误信息
2. 操作数据库 【 Execute SQL 】
输入：
SQL: 执行的SQL语句，支持 SELECT, DELETE, INSERT, UPDATE, CALL。 基本所有的SQL语句都是支持的，可以直接在这里操作数据库。
需要一定的SQL语法知识掌握，可以参考 SQL 语法 | 菜鸟教程 (runoob.com)
输出：
Success： 返回操作是否执行成功
Error No：错误编号，成功返回0
Error Msg: 执行错误返回错误信息
Rows: 执行后输出结果行数
Result：返回数据库结果集，如果是CALL存储过程或者数据库函数则可能返回多个结果集，这样的话就需要 [ Add Result ], 根据实际返回添加
3. 结果集分解
Result 返回的结果集为 一个MAP的数组，一个数组等于一行的信息，这一行的数据保存在一个MAP中。
也可以使用本插件自带功能，把输出结果集转换为JSON。
Good afternoon I bought your database connection plugin, UE 5.4. When compiling a project on Linux, an error occurs:
UATHelper: Packaging (Linux): [368/968] Compile viosocket.cc
UATHelper: Packaging (Linux): D:\Plastic\Plugins\DTMysql\Source\ThirdParty\DTMysqlLib\Private\vio\viosocket.cc(280,1): error: non-void function does not return a value in all control paths [-Werror,-Wreturn-type]
UATHelper: Packaging (Linux): }
UATHelper: Packaging (Linux): ^
UATHelper: Packaging (Linux): 1 error generated.
PackagingResults: Error: non-void function does not return a value in all control paths [-Werror,-Wreturn-type]
UATHelper: Packaging (Linux): [369/968] Compile fse_compress.c
How can I fix it and what could it be related to?
Can only be developed on Windows platform.
Linux distribution package needs to be packaged on Windows.
支持多线程吗？支持在一个节点上运行多条语句吗？
单线程操作， 一个一个的执行
