# Delete
|
||
|
|
|
||
|
|
```go
|
||
|
|
// Delete an existing record
|
||
|
|
db.Delete(&email)
|
||
|
|
//// DELETE from emails where id=10;
|
||
|
|
|
||
|
|
// Add extra SQL option for deleting SQL
|
||
|
|
db.Set("gorm:delete_option", "OPTION (OPTIMIZE FOR UNKNOWN)").Delete(&email)
|
||
|
|
//// DELETE from emails where id=10 OPTION (OPTIMIZE FOR UNKNOWN);
|
||
|
|
```
|
||
|
|
|
||
|
|
### Batch Delete
|
||
|
|
|
||
|
|
```go
|
||
|
|
db.Where("email LIKE ?", "%jinzhu%").Delete(Email{})
|
||
|
|
//// DELETE from emails where email LIKE "%jinhu%";
|
||
|
|
```
|
||
|
|
|
||
|
|
### Soft Delete
|
||
|
|
|
||
|
|
If struct has `DeletedAt` field, it will get soft delete ability automatically!
|
||
|
|
Then it won't be deleted from database permanently when call `Delete`.
|
||
|
|
|
||
|
|
```go
|
||
|
|
db.Delete(&user)
|
||
|
|
//// UPDATE users SET deleted_at="2013-10-29 10:23" WHERE id = 111;
|
||
|
|
|
||
|
|
// Batch Delete
|
||
|
|
db.Where("age = ?", 20).Delete(&User{})
|
||
|
|
//// UPDATE users SET deleted_at="2013-10-29 10:23" WHERE age = 20;
|
||
|
|
|
||
|
|
// Soft deleted records will be ignored when query them
|
||
|
|
db.Where("age = 20").Find(&user)
|
||
|
|
//// SELECT * FROM users WHERE age = 20 AND deleted_at IS NULL;
|
||
|
|
|
||
|
|
// Find soft deleted records with Unscoped
|
||
|
|
db.Unscoped().Where("age = 20").Find(&users)
|
||
|
|
//// SELECT * FROM users WHERE age = 20;
|
||
|
|
|
||
|
|
// Delete record permanently with Unscoped
|
||
|
|
db.Unscoped().Delete(&order)
|
||
|
|
//// DELETE FROM orders WHERE id=10;
|
||
|
|
```
