Hello I need some help on the following 3 part question I have included the table structure below, none of the tables have key constraints. Any help or suggestions would be appreciated. - Thanks for your time.

1.) Create a view called PURITAINCHILDREN view to see the name, age and school year of all children of employees insured by Puritain.

I have tried the following code which I hear is somewhat near the correct code to no avail.
SQL> CREATE VIEW view_puritainchildren (cname, childage, schyear)
2 AS SELECT DISTINCT cname,childage,schyear from child
3 FROM child, insur_co
4 WHERE insur_co.empno = child.empno
5 AND insur_co.empno = 'PURITAIN');
FROM child, insur_co
*
ERROR at line 3:
ORA-00933: SQL command not properly ended

2.) Using the PURITAINCHILDREN view, obtain a list of children whose age is less than or equal to 20 excluding the child whose age is less than 10. Show the name, age, and school year of each child.

3.) Using the PURITAIN CHILDREN view, crate a new view called LITTLEPURITAINCHILDREN consisting of name, age and school year of children whose age is less than 10.

1) You have FROM clause twice (lines 2 and 3)
2) You have an unwanted ")" on line 5
