写法
var name string has, err := engine.Where("id = ?", id).Cols("name").Get(&name) 数据库的name值是NULL
报错信息如下:
sql: Scan error on column index 0: unsupported Scan, storing driver.Value type <nil> into type *string

写法 `var name string has, err := engine.Where("id = ?", id).Cols("name").Get(&name) 数据库的name值是NULL ` 报错信息如下: `sql: Scan error on column index 0: unsupported Scan, storing driver.Value type <nil> into type *string `
