Example 1 with BindBeanList

use of org.jdbi.v3.sqlobject.customizer.BindBeanList in project jdbi by jdbi.

the class SqlStatement method bindBeanList.

/**
 * Bind a parameter for each value in the given list * number of property names,
 * and defines an attribute as the comma-separated list of parameter references (using colon prefix).
 *
 * Used to create query similar to:
 * select * from things where (id, foo) in ((1,'abc'),(2,'def'),(3,'ghi'))
 * <p>
 * Examples:
 * <pre>
 *
 * List&lt;ThingKey&gt; thingKeys = ...
 * List&lt;Thing&gt; things = handle.createQuery("select * from things where (id, foo) in (&lt;thingKeys&gt;)")
 *     .bindBeanList("thingKeys", thingKeys, Arrays.asList("id", "foo"))
 *     .mapTo(Contact.class)
 *     .list();
 * </pre>
 *
 * @param key    attribute name
 * @param values list of values that will be comma-spliced into the defined attribute value.
 * @param propertyNames list of properties that will be invoked on the values.
 * @return this
 * @throws IllegalArgumentException if the list of values or properties is empty.
 * @throws UnableToCreateStatementException If a property can't be found on an value or we can't find a Argument for it.
