How Can I Access and Consolidate Active Plugin Data from Multiple WordPress Databases?

Accessing Active Plugins from Multiple WordPress Databases Simultaneously

WordPress deployments often involve multiple instances, each operating with a distinct database. To manage these instances effectively, it may be necessary to access and consolidate data across multiple databases. One common scenario is retrieving active plugins, which are stored in the 'wp_options' table.

Database Syntax

In MySQL, you can access specific tables within a database using the following syntax:

SELECT * FROM `database`.`table` WHERE condition;

where database is the name of the database and table is the name of the table within that database.

Retrieving Active Plugins from Multiple Databases

To retrieve active plugin settings from multiple databases, you can use the UNION operator, which combines the results of multiple queries into a single result. For example, to retrieve active plugins from databases named database1 and database2, you would use the following query:

SELECT option_value
FROM `database1`.`wp_options`
WHERE option_name="active_plugins"
UNION
SELECT option_value
FROM `database2`.`wp_options`
WHERE option_name="active_plugins";

This query will return a single result containing all active plugin settings from both databases.
