我们写了一个例子是可以正常运行的

package main

import (
   "database/sql" 
   _"dm"
   "fmt"
)

func main() {
   db, _ := sql.Open("dm", "dm://SYSDBA:SYSDBA@localhost:5236?autoCommit=false")
   defer db.Close()
   fmt.Printf("connect ok!\n")
   
   tx, _ := db.Begin()
   tx.Exec("insert into test values(?, ?)",11,"go_dameng")
   tx.Commit()
   fmt.Println("commit ok!")
   
   tx2, _ := db.Begin()
   tx2.Exec("insert into test values(?, ?)",22,"go_dameng")
   tx2.Rollback()
   fmt.Println("rollback ok!")
	
   stmt, _ := db.Prepare("select c1,c2 from test")
   defer stmt.Close()

   rows, _ := stmt.Query()
   defer rows.Close()

   for rows.Next() {
       var c1 string
	   var c2 string

       _ = rows.Scan(&c1, &c2)
       fmt.Printf("%v, %v\n",c1, c2)
   }	

}
