SQL Query Support
This service supports multiple query types:
- Named Parameters:
SELECT name FROM foo WHERE value = :value - SQL IN queries:
SELECT name FROM foo WHERE value IN(:values) - Multiple lookup values:
SELECT name FROM foo WHERE value IN(:values) AND sequence = :sequence AND catalog = :catalog
Caching
The goal of this service is to return values quickly. It has a built-in cache so that your database doesn't get overwhelmed.
This is configurable in the controller settings.
Supported caches
These caches are all built-in to this service. Select your preferable cache in the controller settings.
You can also select the number of items that you want to cache. The caches all keep the most accessed items available by default.
If you don't know which to choose, just go with the default.
