- InnerJoin (Select values that match in both tables):
- operation.property (the column to search for the value),
- operation.searchQuery (the value to search for [will be sanitised by method])
- operation.selection (The columns of both tables to be selected, e.g. users.name, orders.id)
- operation.secondTable (The second table to perform Join operation with)
- operation.matchingParam (Which properties should be matched to get the data, e.g. order.user_id=users.id)
