If I have two tables as shown below, could anyone tell me if and how its possible to create a view
that has only one column that contains the dbName values from both the tutor and student tables?
Thanks in advance
CREATE TABLE tutor
dbId INTEGER ,
dbPassword VARCHAR(8)NOT NULL
CREATE TABLE student
dbId INTEGER NOT NULL PRIMARY KEY,
dbPassword VARCHAR(8) NOT NULL,
dbPersonalTutorId INTEGER NOT NULL

Look into using two queries combined with UNION.... and check into the difference between UNION and UNION ALL, to be sure you use the right one.
Hope this helps,
