golang 批量插入数据 使用gorm框架插入数据的时候,官方没有现成的批量插入方法,可通过自己拼接sql语句,执行原生sql来实现 实现代码 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 func(c *SalesDay)BatchSave(dataSlice []interface{}) (interface{}, error) { varbuffe...

In golang world, gorm is a nice orm framework, but it still not support Batch insert operation. Feature Request: Batch Insert . I will show you guy how to add the feature combine with real world case. Take a look at code snippet: func (repo *repo) CreateBalancesForAsset(ctx context....
// BatchInsertUsers2 使用sqlx.In帮我们拼接语句和参数, 注意传入的参数是[]interface{} func BatchInsertUsers2(users []interface{}) error { query, args, _ := sqlx.In( "INSERT INTO user (name, age) VALUES (?), (?), (?)", users..., // 如果arg实现了 driver.Valuer, sqlx.In 会通过...
其中,gorm.go 是gorm 这个示例程序的主体。使用 gorm 时,相较于 go-sql-driver/mysql,gorm 屏蔽了创建数据库连接时,不同数据库差异的细节,其还封装了大量的操作,如 AutoMigrate、基本对象的 CRUD 等,极大的简化了代码量。 Player 是数据结构体,为数据库表在程序内的映射。Player 的每个属性都对应着 player 表...
