| Be carefull of the new version of postgres !!!! Some inheritances bugss are fiked but not all !!!! In the New version of postgresSQL (7.2.1) inheritance bug was fixed. Now SQL99 is respect for simple inheritance behavior. // Example : create table people( id INT UNIQUE, name VARCHAR); create table mother( nb_son INT) INHERITS(people); create table house (id INT UNIQUE, nbFloor INT, ownerID INT REFERENCES "people"("id")); insert into mother VALUES (1,'first mum',0); insert into mother VALUES (2,'second mum',3); DB=# select * from mother ; id | name | nb_son ----+------------+-------- 1 | first mum | 0 2 | second mum | 3 (2 rows) :) OK DB=# select * from people ; id | name ----+------------ 1 | first mum 2 | second mum (2 rows) :) OK now test if respect SQL99 DB=# select id from people where name='second mum'; id ---- 2 (1 row) :p Ouah !! One bug Fix !!!! cool // Now the references test ( humhum suspens ...... ;-) ) DB=# insert into house values (1,3,2); ERROR: <unnamed> referential integrity violation - key referenced f meens that value id=2 don't exist in people table !!!!! :mad: Non Fix Bug !!!! |
