Annotation Type Update
-
@Target(METHOD) @Retention(RUNTIME) public @interface Update
The update annotation is used to indicate that a method will perform update operation on the database.
This annotation can be configured in two ways:-
annotate the method without providing "where arguments"(UpdateBy)to perform the Update operation by, which will result in deleting the the in the database based on the provided primaryKey. in this approach the method must be void/MyObject/int "methodName"(Connection, Object), where the return type determines if the method returns nothing(void), number of affected rows(int) , Updated object(MyObject).
-
annotate the method and provide the UpdateBy value. In this case the method must be provided as the
following void/int "methodName"(Connection, Object[]), where the first object in
the array of objects is the object to be Updated and the rest is the values of the where arguments
if the objects where not set then the database might throw a SQLException or the library will ignore
the updateBy values, it depends on whether the user overloads the method with a different configuration
for Example:
*@Update(updateBy = {"name"}) // deleteBy values ignored Movie delete(Connection connection, Movie move); *@Update int delete(Connection connection, Object...whargs); // SQLException thrown
