@Retention(value=RUNTIME) @Target(value=METHOD) public @interface BindSqlInsert
For example suppose we want to persist bean Person defined as follow:
public class Person {
public long id;
public String name;
public String surname;
public String birthCity;
public Date birthDay;
}
The associated DAO interface is
@BindDao(Person.class)
public interface PersonDAO {
}
It's possible define a INSERT query with annotation BindSqlInsert. It is possibile to define query parameter simply using method parameter with same name of the bean property.
@BindDao(Person.class)
public interface PersonDAO {
@BindInsert
void insertOne(String name, String surname, String birthCity, Date birthDay);
@BindInsert
long insertTwo(String name, String surname, String birthCity, Date birthDay);
}
Each method parameter will be use like input parameter for query. The name of parameters will be used to map field bean and then the column name of the associated table. If you specify a return type for methods (like method
insertTwo), it has to be of type int, long, Integer, Long. In this case, the return value will be the id value of just inserted row.
The other way to define an INSERT query is using a bean as input parameter:
@BindDao(Person.class)
public interface PersonDAO
{
@BindInsert(excludedFields={"name", "surname"}
void insert(Person bean);
}
You can use attribute value to define which property insert into query or you can use attribute excludedFields to avoid to insert some fields,
but you can not use both attributes in the same method definition. Values of this attribute will be used like bean property name. At the end of the insert, bean will have id value set to last row id used to insert bean into
table. If you specify a return type for methods, it has to be of type int, long, Integer, Long and it will contains same value like row id.
