我想通过网络从 mssql 服务器系统连接 mysql 服务器系统，因为我想将 sql 服务器数据库从 mssql 服务器系统导入或导出到 mysql 服务器系统。
谁能告诉我我该怎么做？
谢谢

尝试使用此脚本，它允许您导入数据。您必须指定表名并在 MySQL 服务器上运行生成的代码。
DDL：
CREATE TABLE Labour.Employee
(
EmployeeID INT IDENTITY (1, 1) PRIMARY KEY NOT NULL
, IsMainWorkPlace BIT NOT NULL
, TabelNumber VARCHAR(6) NULL
, PersonID INT NOT NULL
, DepartmentUID UNIQUEIDENTIFIER NOT NULL
, DateIn DATETIME NOT NULL
, DateOut DATETIME NULL
, PositionID INT NULL
, DatePension DATETIME NULL
, IsLabourUnionMember BIT NOT NULL
, FiringReasonID INT NULL
)
