It is possible to use parameters in queries to make them more flexible and versatile. Parameter values can be set when adding the PocketQuery macro to a Confluence page.
Parameters are included within the Statement (for SQL datasources) or REST URL (for REST datasources) and are marked by a leading colon. A simple SQL example could be:
SELECT Name, Population FROM Country WHERE Continent = :continent
When executing the query, the parameter is replaced with the value set by the user, e.g. "Europe":
SELECT Name, Population FROM Country WHERE Continent = 'Europe'
For SQL queries, it is also possible to choose the type of the parameter, which changes the way it is embedded into the query. For example, strings are enclosed by quotes while integers are inserted without quotes and lists are handled completely different. For a detailed explanation of the parameter types, please refer to the corresponding section within the PocketQuery Documentation.
Additionally, it is possible to allow users to change the parameters without editing the page (using the option "Change params template") or to set the parameters dynamically via URL. For more information on that, please refer to the Documentation of the PocketQuery Macro
