Can't use ORDER BY in subqueries
Hi all,
I tried to use some more complex queries, they contained subqueries. I will shortly desrcibe the situation:
I have two tables (e.g. test and foo) and want to join them. Furthermore I want to preselect a subset of one of the two tables by adding some conditions (e.g. order the records by attribute c and only choosing the biggest one). A query could look like the this:
sql>select * from test join (select * from foo order by c limit 1);
The result I receive is the following:
syntax error, unexpected ORDER, expecting INTERSECT or EXCEPT or UNION or ')' in: "select * from test join (select * from foo order”
On the other hand, I can run the subquery without the main query and I receive a valid result.
Is there a possibility to use subqueries with an ORDER BY statement without separating them into two independent queries?
Regards Leo
Hi
ORDER BY (and LIMIT/OFFSET for that matter) only control the overall shape of the query result set. Hence, they are indeed not supported within subqueries in MonetDB.

Hi,
I understand why Monetdb does’t support ORDER BY in subqueries.
An ORDER BY combined with a LIMIT does influence the size of the query result set. Is there a workaround to use such a query?
Here’s my use case: I’m working with the spatial extension and have a table filled with polygons. Now I want to know the ids of all polygons that intersect the polygon with the biggest area.
Is there a chance to answer this use case with only one query?

This is off the cuff, but why not try some kind of TOP 1 query that would return the first result in your ordered query. That way you can quit using LIMIT within the subquery.

A possible workaround is to enclose the query in a table producing function.

Hi
This recurring question has a simple solution in MonetDB for most of the cases considered. Simple rip out the subquery and encapsulate it in table producing function. The following example shows how:
-- select * from tables where id in (select id from tables limit 1); create function limited() returns table (id integer) begin return select id from tables order by id desc limit 1; end; select * from tables where id in (select * from limited());

Martin,
Your answer to this question is useful but triggers a feature request that I'm very interested in for long :)
The major drawback of your workaround is that the name of the table to be limited is hard-coded inside the function. Which makes this solution impractical for real scenarios.
What is much missed - and would make your solution very useful in practice - is to be able to pass table identifiers as function parameters.
I could produce a long list of issues that would be solved by this ;) On 5 Nov 2014 17:24, "Martin Kersten" Martin.Kersten@cwi.nl wrote:

passing table identifiers IMHO clashes with SQL type system.
passing table-typed arguments might work --- you still need one function per table signature, but no longer per table name; IMHO, there are plans to work on supporting something like that ...

Hi Leo,
could you give an SQL example of the very query you'd like to run but that MonetDB "rejects" due to order by and/or limit in a sub query?
Thanks!

Hi,
I have two tables: CREATE TABLE lines (ID INT, size INT, line GEOMETRY); CREATE TABLE polygons (ID INT, size INT, polygon GEOMETRY);
The query I want to call is the following: SELECT COUNT(*) FROM POLYGONS one JOIN (SELECT LINE FROM LINES ORDER BY Length(line) DESC LIMIT 1) two ON "Intersect"(one.polygon, two.line) = TRUE;
I tried out to create a function that replaces the use of the subquery: create function line_max() returns table (id integer) begin return select id from lines order by Length(line) desc limit 1; end;
select count(*) From polygons one join lines two ON "Intersect"(one.polygon, two.line) = TRUE where two.id in (select id from line_max());
The query started without errors but it stops with the following error: HEAPalloc: Insufficient space for HEAP of 7200000000 bytes.
Thanks Leo

Hi Leo,
could you give an SQL example of the very query you'd like to run but that MonetDB "rejects" due to order by and/or limit in a sub query?

Hi,
I understand why Monetdb does’t support ORDER BY in subqueries.
An ORDER BY combined with a LIMIT does influence the size of the query result set. Is there a workaround to use such a query?
Here’s my use case: I’m working with the spatial extension and have a table filled with polygons. Now I want to know the ids of all polygons that intersect the polygon with the biggest area.
Is there a chance to answer this use case with only one query?
Regards Leo

ORDER BY (and LIMIT/OFFSET for that matter) only control the overall shape of the query result set. Hence, they are indeed not supported within subqueries in MonetDB.

Hi all,
I tried to use some more complex queries, they contained subqueries. I will shortly desrcibe the situation:
I have two tables (e.g. test and foo) and want to join them. Furthermore I want to preselect a subset of one of the two tables by adding some conditions (e.g. order the records by attribute c and only choosing the biggest one). A query could look like the this:
*sql>select * from test join (select * from foo order by c limit 1);*
The result I receive is the following:
*syntax error, unexpected ORDER, expecting INTERSECT or EXCEPT or UNION or ')' in: "select * from test join (select * from foo order**”*
On the other hand, I can run the subquery without the main query and I receive a valid result.

the (intermediate) result might still be as large as polygons in case the longest lines intersects with all polygons ...

the solution you proposed works out (the one without the function). I used the following to get what I want: SELECT COUNT(*) FROM POLYGONS one JOIN (SELECT LINE FROM LINES where length(line) = (select max(length(line)) from lines) ) two ON "Intersect"(one.polygon, two.line) = TRUE;

Hi,
in case there is a single longest line in LINES, how about
SELECT COUNT(*) FROM POLYGONS one JOIN (SELECT LINE FROM LINES where length(line) = (select max(length(line)) from lines) ) two ON "Intersect"(one.polygon, two.line) = TRUE;
Or, if there is no single longest line in LINES, but ID is unique in lines (i.e., also LIMIT 1 would choose among all equally long longest lines one arbitrary, implementation dependent, possibly non-deterministic line)
SELECT COUNT(*) FROM POLYGONS one JOIN (SELECT LINE FROM LINES where ID = (select max(ID) from LINES where length(line) = (select max(length(line)) from lines) ) ) two ON "Intersect"(one.polygon, two.line) = TRUE;
?
