Is it possible to write a SQL query to return specific rows, but then join some columns of those rows with another table

I hope this helps you . This is how you do the join in general. It will return all apples whether or not a color is specified:
FROM apples a
LEFT OUTER JOIN colors c ON a.color_id = c.id
FROM apples a
INNER JOIN colors c ON a.color_id = c.id
WHERE a.color_id = 3
FROM apples a 
INNER JOIN colors c ON a.color_id = c.id 
INNER JOIN orchards o ON a.orchard_id = o.id 
WHERE a.color_id = 3 and a.orchard_id = 5

With these it helps I have table where I store data on basis of date. , Try this
  SELECT t1.* 
     `national` t1, `national` t2 
      t1.upload_date = '2015-08-01' and t2.upload_date='2015-08-04' and
      -- put your columns here that you want to compare for same DATA
      -- like t1.name=t2.name and etc...

I think the issue was by ths following , As Okneloper indicated, as soon as you use ->callbacks, a collection is returned. The trick is to keep this as a builder until you are finished with the query.
$callbacks = Auth::user()->callbacks()->where('datetime', '>', '0000-00-00 00:00:00')->orderBy('datetime')->take(10)->get();

This might help you Need an sql query which results those records whose status is complete for a same id. For example, mytable is the table name which has various records. We need to find all those ids whose status is complete for that same id , This will find the ids where all its rows have a status of complete:
FROM   mytable
HAVING COUNT(*) = COUNT( CASE status WHEN 'complete' THEN 1 END )

Hope that helps Now, that's some content to work with.
As it is often the case with my answer, I will try to give you a working solution rather than an optimized one.
cursor.execute(""" select * from employee """)
results = cursor.fetchall()

employeeIDs = []
managerIDs = []
directorIDs = []
dates = []
for result in results:
cursor.execute(""" select * from manager """)

dataall = cursor.fetchall()

for data in dataall:
    employee = data[0]
    manager = data[1]
    director = data[2]
    director_tableb = data[3]

    while (i<len(employeeIDs)):
        if (employeeIDs[i] == employee) & (managerIDs[i] == manager) & (directorIDs[i] == director):
            cursor.execute(""" Insert into Table_C (%s, %s, %s, %s, %s) """, (employeeIDs[i], managerIDs[i], directorIDs[i], director_tableb, dates[i]))
        i =+ 1
