Answer 1

Try this:

SELECT a.id, MAX(IF(b.typename = 'CL', a.available, 0)) CL, 
       MAX(IF(b.typename = 'ML', a.available, 0)) ML
FROM table1 a
INNER JOIN table2 b ON a.typeid=b.typeid
GROUP BY a.id;

Use SUM function if you want to sum of the data from available column for particualr type else use the same query as ii is.
