### Question
Please list the names of the institutes in the state of Alabama whose all graduates in total exceeded 500 in 2011?

### Hint
names of the institutes refers to chronname; graduates refers to grad_cohort; grad_cohort > 500; in 2011 refers to year = 2011; all students refer to race = 'X'.

### SQL
SELECT DISTINCT T1.chronname FROM institution_details AS T1 INNER JOIN institution_grads AS T2 ON T2.unitid = T1.unitid WHERE T1.state = 'Alabama' AND T2.year = 2011 AND T2.race = 'X' AND T2.grad_cohort > 500
