The following will give you all the records in table1 that do not exist
in table two:

select a.key, a.description from table1 a
exception join table2 b using (key);

further, this will copy the missing records from table1 into table2

insert into table2 (
select a.key, a.description from table1 a
exception join table2 b using (key)
)

Subject: SQL question

Hi
I have 2 tables which has similar structure, i want to
write a sql statement to compare the 2 tables and find
the missing keys from one
For example
Table 1
Key Description
001 This is one
002 This is two

Table 2
Key Description
001 this is one

Now i want to write a query to find out, 002 is
missing in table 2, and may be a query to insert 002
into table2
Any ideas?

Ashish
