Detailed Description

Constructor & Destructor Documentation
◆ __construct()
| BatchedQueryRunner::__construct | ( | ) |
Default constructor.
Children should call this first if implementing their own constructors
Reimplemented from Maintenance.

Member Function Documentation
◆ execute()
| BatchedQueryRunner::execute | ( | ) |
Do the actual work.
All child classes will need to implement this
Reimplemented from Maintenance.

◆ getDbType()

Does the script need different DB access? By default, we give Maintenance scripts normal rights to the DB.
Sometimes, a script needs admin rights access for a reason and sometimes they want no access. Subclasses should override and return one of the following values, as needed: Maintenance::DB_NONE - For no DB access at all Maintenance::DB_STD - For normal DB access, default Maintenance::DB_ADMIN - For admin DB access
- Returns
- Integer
