golang 创建DM数据库连接实现

1、开发环境：go 1.19.1 windows/amd64 2、问题描述：创建DM数据库连接报 error.dsn.invalidSchema 3、相关代码 ``` import ( "database/sql" "dm" "fmt" "io/ioutil" "time" ) var db *sql.DB var err error func main() { driverName := "dm" dataSourceName := "TCM:Tcm#123@tcp(10.92.225.249:5236/dwglsvc?)" if db, err = connect(driverName, dataSourceName); err != nil { fmt.Printf("%v\n",err) return } } func connect(driverName string, dataSourceName string) (*sql.DB, error) { var db *sql.DB var err error if db, err = sql.Open(driverName, dataSourceName); err != nil { return nil, err } if err = db.Ping(); err != nil { return nil, err } fmt.Printf("connect to \"%s\" succeed.\n", dataSourceName) return db, nil } ``` 报错信息（对应到sql.Open）  希望得到正确的创建DM连接的方式，感觉dataSourceName的变量写法有问题。望得到各位大佬帮助
