Thread: How to force select to return exactly one row

How to force select to return exactly one row

From
"Andrus"
Date:
Autogenerated select statement contains 0 .. n left joins:

SELECT somecolumns
 FROM ko
LEFT JOIN t1 ON t1.primarykey= ko.t1foreignkwey
...
LEFT JOIN tn ON tn.primarykey= ko.tnforeignkwey
WHERE ko.primarykey='someprimarykeyvalue';

This select can return only 0 or 1 rows depending if ko row with primary key
'someprimarykeyvalue' exists or not.

Problem:

if there is no searched primary key row in ko database, select should also
return empty row.

To get this result I added right join:

SELECT somecolumns
 FROM ko
RIGHT JOIN (SELECT 1) _forceonerow ON true
LEFT JOIN t1 ON t1.primarykey= ko.t1foreignkwey
...
LEFT JOIN tn ON tn.primarykey= ko.tnforeignkwey
WHERE ko.primarykey is null or ko.primarykey='someprimarykeyvalue';

but it still does not return row if primary key row 'someprimarykeyvalue'
does not exist.

How to force this statement to return one row always ?

Thank you. SELECT statement returns lot of columns.

It's a bit difficult to decipher what you're looking for
(what do you mean by "empty row"?), but you may want to try
something along the lines of:

| SELECT v.primarykey, ko.somecolumns
|   FROM (VALUES ('someprimarykeyvalue')) AS v (primarykey)
|   LEFT JOIN ko ON v.primarykey  = ko.primarykey
|   LEFT JOIN t1 ON t1.primarykey = ko.t1foreignkey
|   [...]
|   LEFT JOIN tn ON tn.primarykey = ko.tnforeignkey;

Whether that suits your needs depends very much on the data
structure and the tools you use.

Re: How to force select to return exactly one row

From

Ah yes sorry I missed the multi-columns. "My way" doesn't work for that.
If Tim's suggestion doesn't work for you, you could try a union...
it's fairly nasty and you will always have your "fake" row in the result.

Also I too am confused by "empty row". Are you trying to loop through the results in code and it fails if there are no rows at all?
Or some other equally odd thing? =)

Anyway here is an example UNION that I think would work (but note, this row will always be included even when your statement returns something, so it might not work for you).

(YOUR SELECT HERE)
UNION
(SELECT '','',1,1,perfectly_matched_datatype_cols_here); --those first couple are just examples

Mind you, I think this is nasty and would highly suggest taking another look at the code that is using this statement to see if you can deal more gracefully with an empty resultset.

hope this helps,

Re: How to force select to return exactly one row

From
"Brent Wood"

Use a case staement to test for a null output, & return whatever you want in the event of it being null, else the actual value:

from the top of my head, something like:

SELECT case when
(select somecolumns
 FROM ko
 RIGHT JOIN (SELECT 1) _forceonerow ON true
 LEFT JOIN t1 ON t1.primarykey= ko.t1foreignkwey
...
 LEFT JOIN tn ON tn.primarykey= ko.tnforeignkwey
 WHERE ko.primarykey is null or ko.primarykey='someprimarykeyvalue') not null

then (select somecolumns

 FROM ko
 RIGHT JOIN (SELECT 1) _forceonerow ON true
 LEFT JOIN t1 ON t1.primarykey= ko.t1foreignkwey
...
 LEFT JOIN tn ON tn.primarykey= ko.tnforeignkwey
 WHERE ko.primarykey is null or ko.primarykey='someprimarykeyvalue')

else
 0
end

It does require the query to be run twice, so does have extra overhead. You could wrap a function around this to get & store the result & test that, then having stored it you can use it for the output value without a second query. All depends on how much overhead there is in teh query.

It doesn't, but that's not promised for every data set, ev-
ery PostgreSQL version, every phase of the moon. To quote
<URI:http://www.postgresql.org/docs/8.4/interactive/queries-union.html>:

| UNION effectively appends the result of query2 to the result
| of query1 (although there is no guarantee that this is the
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| order in which the rows are actually returned). Furthermore,
  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| it eliminates duplicate rows from its result, in the same
| way as DISTINCT, unless UNION ALL is used.

SQL deals with (unordered) sets, and therefore any use of
"LIMIT" without "ORDER BY" indicates a bug waiting to bite
you when you least expect it.

Returned row is used to enter report parameters, search conditions etc. in
dialog forms where exactly one row should be
present always.
Code is simpler if it can assume that single row is always returned: in this
case it can generate only update statement.
Otherwize separate branch should check for insert or update clause. This
makes app code complicated.

I changed appl code to:

1. Execute original select statement.
2. If it returns no rows, add one row:

insert into ko (primarykey) ('primarykeyvalue');

3. Re-execute original select statement.

This requires 3 database calls from application and two times to execute
query.

How to implement this using single db call and execute query only once ?

if it possible to use

CREATE TEMP TABLE temp AS
  original_select ON COMMIT DROP;

IF (SELECT COUNT(*) FROM temp) =0 THEN
  INSERT INTO temp DEFAULT_VALUES;
  ENDIF;

SELECT * FROM temp;

The reason this won't return a row if there is no matching PK is that
the WHERE clause is applied after all the joins to filter the overall
result set.

So to get what you want, you would need to re-arrange that to something like:

SELECT original_query.* FROM
( Original query including WHERE clause ) AS original_query
RIGHT JOIN (SELECT 1) AS one_row ON true;

Should I try 9.0 release or other idea how to fix without removing primary
