Jdbi - how to bind a list parameter in Java?

Question

We have an SQL statement which is executed by Jdbi (org.skife.jdbi.v2). For binding parameters we use Jdbi\'s bind method:

Handle h         


        

Answer 1

I just wanted to add an example since I recently spent considerable time getting a slightly more complex scenario to work :

Query :

select * from sometable where id <:id and keys in ()

What worked for me :

@UseStringTemplate3StatementLocator
public interface someDAO { 

    ....
    ....
    // This is the method that uses BindIn
    @Mapper(someClassMapper.class)
    @SqlQuery("select something from sometable where age \\< :age and name in ()")
    List someMethod (@Bind("age") long age, @BindIn("names") List names);

    @Mapper(someClassMapper.class)
    @SqlQuery("select something from sometable where id = :id")
    List someMethod1 (@Bind("id") long id);
    ...
    ...

}

Note: I did have to also add the below dependency since I am using

@UseStringTemplate3StatementLocator 

    org.antlr
    stringtemplate
    3.2.1

The main thing to observe in the above example : You only need to escape the less than operator (i.e. < ) and not the <> that surround the collection variable (names).

As you can see I did not use a sql.stg file to write my queries in. Initially I incorrectly assumed that when using @UseStringTemplate3StatementLocator , we have to write the queries in the sql.stg file. However, somehow I never got my sql.stg file to work and I eventually reverted back to writing the query within the DAO class using @SqlQuery.
