 Hi,

  I would like to say:

create table test1 (array1 int4[]);
insert into test1 values ('{123,234,345}');
insert into test1 values ('{456,567,678}');

 now what I don't know how to do:

-- consider contents of array:
select * from test1 where array1 CONTAINS 567;

-- APPEND '789' to array in second row:
update test1 set array1=(select array1 from test1 where array1 CONTAINS 
'567' UNION select '789');


 How do I go about expressing and operating on the contents of an array ?


    Thanks,

       John
