【SQL SERVER】SQL SERVER數據庫實時同步到MySQL

SQL Server 數據實時同步到MySQL中（先做記錄，待會兒再詳細規劃）

EXEC sp_addlinkedserver
@server='YCGA_MySQL', --ODBC裏面data source name 上圖記住的名字
@srvproduct='MySQL', --自己隨便
@provider='MSDASQL', --固定這個
@datasrc=NULL,
@location=NULL,
@provstr='DRIVER={MySQL ODBC 8.0 Unicode Driver};SERVER=IP地址;DATABASE=數據庫名;UID=richard;PORT=3306;',   
--這裏面的參數，分別是驅動名稱，比如我的是MySQL ODBC 8.0 一般只改下版本號就可以，後面是數據庫地址，數據庫名，UID就是唯一標識這個自己起就行，最後的是數據庫端口號
@catalog = NULL

exec sp_addlinkedsrvlogin
@rmtsrvname='YCGA_MySQL' ,----ODBC裏面data source name 跟上面的一樣
@useself='false' ,
@rmtuser='賬號' ,---mysql賬號
@rmtpassword='密碼' ;--mysql賬號其密碼
