How to omit '' columns in Upsert?

[jiaweisizzz]

Your Question

I want to skip '' values when updating with Upsert.

The document you expected this should be explained

type Test struct {
	Id   int64  `gorm:"column:id; primaryKey"`
	Name string `gorm:"column:name"`
        Age  int    `gorm:"column:age"`
}

d.MDb.Debug().Table("test").Clauses(clause.OnConflict{
	Columns:   []clause.Column{{Name: "id"}},
	DoUpdates: clause.AssignmentColumns([]string{"name", "age"}),
}).CreateInBatches(&test, 10)

Expected answer

We have a record

|id|nam|age|
|--|---|---|
|1|hello|18|

I want to update this record, but I want to keep the value of 'hello'

{"id": 1, "name":"", "age": 19}
