Talk:QUEL query languages

QUEL does not support relational algebraic operations such as intersection, minus or union inherently.

Errors
QUEL statements are always defined by tuple variables...

Not correct, the table can act as its own. In fact, the example could be written (more simply) as:

create student (name = c10, age = i4, sex = c1, state = c2) append to student (name = "philip", age = 17, sex = "m", state = "FL") retrieve (student.all) where student.state = "FL" replace student (age=student.age+1) retrieve (student.all) delete student where student.name="philip"

 is  

To store the results of the retrieve in a new table, specify into .(In interactive QUEL, if you do not specify into , the result is displayed.) A table with this name (owned by the user) must not already exist. The current user is the owner of the new table.

I've updated code to

create table w as select (e.salary / (e.age - 18)) as comp from employee as e where e.name = "Jones"
