#LINE 1: declare which database fields (columns) you want to include in your output. 
#You can include any fields from any of the tables you are joining (in this case: page, categorylinks, revision)

#LINE 2: declare which wiki you are pulling data from. 
#In this case, commonswiki_p. You can find a full list here: https://tools.wmflabs.org/tools-info/?dblist=s1.labsdb

#LINE 3: join the page table with the categorylinks table on their COMMON KEY, which is the id of the page. 

#LINE 4: join the page table with the revision table on their COMMON KEY, which is the id of the page. 

#LINE 5: specify the numeric namespace(s) of the pages you want to get information for. 
#There is a list of standard namespaces here: https://en.wikipedia.org/wiki/Wikipedia:Namespace

#LINE 6: specify the category(ies) that the pages are in. If you wanted to get pages from multipe categories, 
#you would write the query the same way: AND cl.cl_to IN ("My_first_category", "Another_category")

#LINE 7: specify that you want to return the revision information from the FIRST revision to the page. 
#the "parent" of a revision is the previous revision to that page. 
#The first revision to a page doesn't have a "parent", so the value for rev_parent_id will be 0.
