@BindSqlInsert

Allow inserting a bean into the database. You can use bean as the unique method parameter or method parameters like bean property, but you can not use mixed case.

Attributes

  • conflictAlgorithm: specifies the conflict algorithm to apply during the insert operation. See here for more information.
  • excludedFields: properties to exclude into INSERT command. To use only if the method has only one parameter and its type is the same of supported bean.
  • fields: allows to specify which fields method need to take from bean used as input parameter.
  • value: bean properties to include into INSERT command. To use only if method has only one parameter and its type is the same of supported bean.
  • includePrimaryKey: Allow to include primary key into INSERT command. To use only if the method has only one parameter and its type is the same of supported bean.
  • jql: allows specifying the entire query with JQL.

Usage

Suppose we want to persist bean Person defined as follow:

@BindType
public class Person {
  public long id;
  public String name;
  public String surname;
  public String birthCity;
  public Date birthDay;
}

There are two kind of INSERT:

  • Raw insert: method parameters are directly used like table column: all method parameter's name are used are transformed in column with same name. It is possibile define an alias with @BindSqlParam. If you specify a return type for methods, it has to be of type int, long, Integer, Long. In this case, the return value will be the inserted row's id. @BindSqlParam annotation can be used to specify a different column name associated to a specific method's parameter. Moreover, you can use boolean as return type, just to receive true if insert operation was completed (row id != -1).

  • Managed bean insert: method has only one managed bean as parameter: method accepts only one managed bean type parameter. It is possible to use excludedFields attribute to avoid to insert some fields, or you can use includeFields attribute to include only specific fields. If you specify a return type for methods, it has to be of type int, long, Integer, Long and it will contains inserted rows count, or boolean to receive a true value if insert statement was successfully completed (row id != -1).

So define a DAO interface for class Person:

@BindDao(Person.class)
public interface PersonDAO {
 
  // raw insert - Method using a bean type parameter
  @BindSqlInsert
  void insertOne(String name, String surname, String birthCity, Date birthDay);
 
  // raw insert - Method use a bean type parameter
  @BindSqlInsert
  long insertTwo(String name, String surname, String birthCity, @BindSqlParam("birthDay") Date date);

  // managed bean insert - method use its parameters like bean properties
  @BindSqlInsert(excludedFields={"name", "surname"})
  void insertThree(Person bean);
}

For interface PersonDAO, Kripton annotation processor will generate the following Person DAO implementation:

/**
 * <p>
 * DAO implementation for entity <code>Person</code>, based on interface <code>PersonDAO</code>
 * </p>
 *
 *  @see Person
 *  @see PersonDAO
 *  @see PersonTable
 */
public class PersonDAOImpl extends AbstractDao implements PersonDAO {
  public PersonDAOImpl(BindPersonDataSource dataSet) {
    super(dataSet);
  }

  /**
