Since `delete` is keyword in C++ that has a different meaning than `delete` in SQL, sqlpp11 calls the method remove. There is no detailed documentation available yet, but here is an example that might help if you have read about [select statements](Select.md) already:
|
|
|
|
```C++
|
|
db(remove_from(tab).where(tab.alpha == tab.alpha + 3));
|
|
```
|
|
|
|
## Removing using multiple tables as condition:
|
|
|
|
```C++
|
|
test_sqlpp::Users usr;
|
|
test_sqlpp::UsersForms usr_forms;
|
|
test_sqlpp::Forms form_;
|
|
|
|
db(remove_from(usr_forms).using_(usr, form_, usr_forms).where(
|
|
usr_forms.iduser == usr.id
|
|
and usr.username == username
|
|
and usr_forms.idform == form_.id
|
|
and form_.name == form_name
|
|
));
|
|
```
