Go 驱动使用占位符方式执行语句报错（好像不会自动添加双引号）

[Daneel-Li]

驱动版本 _ "github.com/taosdata/driver-go/v3/taosWS"， 显示指向v3@v3.5.6

建表及手动测试都没问题：
create table demo(_ts timestamp, col1 varchar(16), col2 varchar(16)); // 建表语句
insert into demo values(NOW(), "123","123"); //手动执行成功
insert into demo values(NOW(), "123","abc"); //手动执行成功

但是用代码占位符方式写数据报错：
`
func Test_InsertDemo(t *testing.T) {
cfg := config.LoadConfig("../../../config.json").Taos

var taosUri = fmt.Sprintf("%s:%s@%s(%s)/%s", cfg.Username, cfg.Password, cfg.Protocol, cfg.Address, cfg.DBName)
if len(cfg.Param) > 0 {
	taosUri = fmt.Sprintf("%s?params=%s", taosUri, cfg.Param)
}

db, err := sql.Open("taosWS", taosUri)
if err != nil {
	fmt.Println("failed to connect TDengine, err:", err)
	t.Fail()
}
if err = db.Ping(); err != nil {
	t.Fail()
}

stmt := "INSERT INTO demo values(?,?,?)"
if _, err := db.Exec(stmt, time.Now(), "123", "123"); err != nil { //成功
	fmt.Println("1 exec failed:", err.Error())
} else {
	fmt.Println("1: success")
}

//失败，报错syntax error near 'abc);' (invalid data or symbol) (0.000197s)
// 和手动执行：insert into demo values(NOW(), "123",abc); 报错一样
if _, err := db.Exec(stmt, time.Now(), "123", "abc"); err != nil { //失败，报错syntax error near 'abc);' (invalid data or symbol) (0.000197s)
	fmt.Println("2 exec failed: ", err.Error())
} else {
	fmt.Println("2: success")
}

}
打印结果：
=== RUN Test_InsertDemo
1: success
2 exec failed: [0x216] syntax error near 'abc)' (invalid data or symbol)
