Here is a patch that removes contrib/array, leaving only the README with
some examples of the new syntax and a reference to the documentation. Joe Conway.

Array iterator functions, by Massimo Dal Zotto <dz@cs.unitn.it>
|
||||
Copyright (C) 1999, Massimo Dal Zotto <dz@cs.unitn.it>
|
||||
Array iterator functions have been removed as of PostgreSQL 7.4, because
|
||||
equivalent functionality is now available built in to the backend.
|
||||
|
||||
This software is distributed under the GNU General Public License
|
||||
either version 2, or (at your option) any later version.
|
||||
For example, previously, using contrib/array, you might have used the
|
||||
following construct:
|
||||
|
||||
create table t(id int4[], txt text[]);
|
||||
|
||||
This loadable module defines a new class of functions which take
|
||||
an array and a scalar value, iterate a scalar operator over the
|
||||
elements of the array and the value, and compute a result as
|
||||
the logical OR or AND of the iteration results.
|
||||
For example array_int4eq returns true if some of the elements
|
||||
of an array of int4 is equal to the given value:
|
||||
-- select tuples with some id element equal to 123
|
||||
select * from t where t.id *= 123;
|
||||
|
||||
array_int4eq({1,2,3}, 1) --> true
|
||||
array_int4eq({1,2,3}, 4) --> false
|
||||
Now you would do this instead:
|
||||
|
||||
If we have defined T array types and O scalar operators we can
|
||||
define T x O x 2 array functions, each of them has a name like
|
||||
"array_[all_]<basetype><operation>" and takes an array of type T
|
||||
iterating the operator O over all the elements. Note however
|
||||
that some of the possible combination are invalid, for example
|
||||
the array_int4_like because there is no like operator for int4.
|
||||
-- select tuples with some id element equal to 123
|
||||
select * from t where 123 = any (t.id);
|
||||
|
||||
We can then define new operators based on these functions and use
|
||||
them to write queries with qualification clauses based on the
|
||||
values of some of the elements of an array.
|
||||
For example to select rows having some or all element of an array
|
||||
attribute equal to a given value or matching a regular expression:
|
||||
-- or you could also do this
|
||||
select * from t where 123 = some (t.id);
|
||||
|
||||
create table t(id int4[], txt text[]);
|
||||
Similarly, if using contrib/array, you did the following:
|
||||
|
||||
-- select tuples with some id element equal to 123
|
||||
select * from t where t.id *= 123;
|
||||
-- select tuples with all txt elements matching '^[A-Z]'
|
||||
select * from t where t.txt[1:3] **~ '^[A-Z]';
|
||||
|
||||
-- select tuples with some txt element matching '[a-z]'
|
||||
select * from t where t.txt *~ '[a-z]';
|
||||
Now do this instead:
|
||||
|
||||
-- select tuples with all txt elements matching '^[A-Z]'
|
||||
select * from t where t.txt[1:3] **~ '^[A-Z]';
|
||||
-- select tuples with all txt elements matching '^[A-Z]'
|
||||
select * from t where '^[A-Z]' ~ all (t.txt[1:3]);
|
||||
|
||||
The scheme is quite general, each operator which operates on a base type
|
||||
can be iterated over the elements of an array. It seem to work well but
|
||||
defining each new operator requires writing a different C function.
|
||||
This is tedious, and error-prone since one must take care that the correct
|
||||
datatypes are associated with the selected underlying function.
|
||||
Can anyone suggest a better and more portable way to do it ?
|
||||
