由于db.Exec函数为

Since the db.Exec function is variadic, one option (that actually does only make a single network roundtrip) is to construct the statement yourself and explode the arguments and pass them in.

示例代码:

func BulkInsert(unsavedRows []*ExampleRowStruct) error {
    valueStrings := make([]string, 0, len(unsavedRows))
    valueArgs := make([]interface{}, 0, len(unsavedRows) * 3)
    for _, post := range unsavedRows {
        valueStrings = append(valueStrings, "(?, ?, ?)")
        valueArgs = append(valueArgs, post.Column1)
        valueArgs = append(valueArgs, post.Column2)
        valueArgs = append(valueArgs, post.Column3)
    }
    stmt := fmt.Sprintf("INSERT INTO my_sample_table (column1, column2, column3) VALUES %s", 
                        strings.Join(valueStrings, ","))
    _, err := db.Exec(stmt, valueArgs...)
    return err
}

在我进行的一次简单测试中，此解决方案在插入10,000行时比其他答案中介绍的开始，准备，提交"快大约4倍-尽管实际的改进很大程度上取决于您的个人设置，网络延迟，等

In a simple test I ran, this solution is about 4 times faster at inserting 10,000 rows than the Begin, Prepare, Commit presented in the other answer - though the actual improvement will depend a lot on your individual setup, network latencies, etc.
