INSERT RULE

Hi,

I test a configuration where one table is divided in 256 sub-table.
And I use a RULE to offer a single view to the data.

For INSERT I have create 256 rules like:
CREATE RULE ndicti_000 AS ON INSERT TO ndict
WHERE (NEW.word_id & 255) = 000 DO INSTEAD
INSERT INTO ndict_000 VALUES( NEW.url_id, 000, NEW.intag);
CREATE RULE ndicti_001 AS ON INSERT TO ndict
WHERE (NEW.word_id & 255) = 001 DO INSTEAD
INSERT INTO ndict_001 VALUES( NEW.url_id, 001, NEW.intag);
And that works, a bit slow.

I try to do:
CREATE RULE ndicti AS ON INSERT TO ndict
DO INSTEAD INSERT INTO 'ndict_' || (NEW.word_id & 255)
VALUES( NEW.url_id, NEW.word_id, NEW.intag);
I got an error on 'ndict_' .
I did not found the right syntax.

Any help is welcomed.

Cordialement,
