Result Maps

+Parameter Maps and +Inline parameters + map object properties to parameters in a database query. Result Maps +finish the job by mapping the result of a database query (a set of columns) to +object properties. Next to Mapped Statements, the Result Map is probably one +of the most commonly used and most important features to understand.

+ +

A Result Map lets you control how data is extracted from the result of a +query, and how the columns are mapped to object properties. A Result Map can +describe the column type, a null value replacement, and complex property +mappings including Collections. The following example shows the structure +of a <resultMap> element.

+ + + + + + + + + + +

In the above example, the [brackets] indicate optional attributes. +The id attribute is required and provides a name for the statement to +reference. The class attribute is also required, and specifies the full +name of a PHP class. This is the class that will be instantiated and populated +based on the result mappings it contains.

+ +

The resultMap can contain any number of property mappings that map object +properties to the columns of a result element. The property mappings are +applied, and the columns are read, in the order that they are defined. +Maintaining the element order ensures consistent results between different +drivers and providers.

+ +
Note: +As with parameter classes, the result class must be a PHP class object or +array instance. +
+ +

Extending resultMaps

+

The optional extends attribute can be set to the name of another +resultMap upon which to base this resultMap. All properties of the +"parent" resultMap will be included as part of this resultMap, and +values from the "parent" resultMap are set before any values specified +by this resultMap. The effect is similar to extending a class.

+ +
Tip: +The "parent" resultMap must be defined in the file before the extending +resultMap. The classes for the parent and child resultMaps need not be +the same, and do not need to be related in any way. +
