im doing some training and having issues with some queries i have 4 tables and sub classes set as

Teacher - teacher ID, name , music style, lessons booked, date joined, postcode

Band - band ID, date joined, music style

the queries i have are

* list all new students who have joined after the 1st of july order by joined date
* list of all underage males musicians and their age sorted by first name
* count of teachers from each post code
* list of all current lessons booking sorted bu the style of music and the booking date
* a report on the students enrolled, the style of music and the teacher

these are the once i have tried if someone can help me with them

1. select * from student where datejoined='1/7/18' sort by datejoined asc;
2. select * from student where student gender ='male' and student age < 18 sort by student name;
3. select * from teacher count teacher from postcode;

Welcome to the forum. Please read the OraFAQ Forum Guide and How to use code tags and make your code easier to read

Every one of your example queries has syntax errors. For example, when I run your first query:
orclx>
orclx>  select * from student where datejoined='1/7/18' sort by datejoined asc;
 select * from student where datejoined='1/7/18' sort by datejoined asc
                                                 *
ERROR at line 1:
ORA-00933: SQL command not properly ended


orclx>
SORT is not a key word in SQL. What training are you following? Which books and courses?
