hi group,
trying to create foreign key:
ALTER TABLE porder1 ADD CONSTRAINT order_exist
FOREIGN KEY (docuuserid) REFERENCES trade(tradeid) ON DELETE RESTRICT;
column docuuserid is integer in porder1
column tradeid is serial in trade and belong to primary key (single column)
getting In EMS PostgreSQL
ERROR: insert or update on table "porder1" violates foreign key constraint "order_exist"
DETAIL: Key (docuuserid)=(8415) is not present in table "trade".
In PostgreSQL Code Factory
SQL Error: ERROR: insert or update on table "porder1" violates foreign key constraint "order_exist"
DETAIL: Key (docuuserid)=(8415) is not present in table "trade".
postgresql 8.4.4-1 on windows 7 ultimate 64 bit standard installation
I'm not able to figure out what should be a problem.
During the foreign key creation, database checks if all rows are correct, and they are not. There is a row in the porder1 table where field docuuserid = 8415 and there is no row in the table trader where tradeid=8415.
