I am having problems trying to create the following. Any suggestions
would be greatly appreciated.
CREATE TABLE "t0" (
"id" integer,
"table" character(1),
"product" character(1),
Primary Key ("id", "table")
);
CREATE TABLE "t1" (
"id" integer,
"table" character(1),
"product" text,
Primary Key ("id", "table")
);
CREATE TABLE "t3" (
"num" integer,
"id" integer REFERENCES t0 and t1,
"table" character(1) REFERENCES t0 and t1,
Primary Key ("num", "id", "table")
);
Is it possible to have a foreign key reference two tables like in the
above example if so how would I do it. I am using postgresql v 7.1.2.
Thanks in advance
