@id is not friendly to insert map struct

go-gorm/playground#739

Description

The data does not exist in multiple databases，and i just know the map struct, i want insert the data into multiple databases.

if I use createForUpdate logic，and the same logic is executed simultaneously in multiple databases，if not set Model, just know the table name. the same map will add “@id”，causing some SQL statements to fail execution.

For example:
`

    updateList := make([]map[string]interface{}, 0)  // the map will be add '@id'   

    columns := make([]clause.Column, 0)    

    updateColumns := make([]string, 0)  

 for _, v := range req.dbList {   
                   dbName := v

		db := global.GVA_DBList[dbName]  

		err := db.Table(req.table).Clauses(clause.OnConflict{  

			Columns:   columns,  
                            
			DoUpdates: clause.AssignmentColumns(updateColumns),   

		}).Create(&updateList).Error  
		if err != nil {  
			errDbList = append(errDbList, dbName)  
			isAllDone = false  
		}  
}  

`
Error Msg: Error 1054 (42S22): Unknown column '@id' in 'field list'

Will the same issue also occur during insert, This is not very compatible with old versions.
