Question

i m trying to import records from one table to another table.

i m having tables suppose A,B,C,D.
i m importing records from table A to table B.
Table B has two foreign keys which are primary keys in table C and D.
I m using query as below::

INSERT INTO B(userid,behaviorid,userNid,behaviorNid,timestamp)SELECT userid,behaviorid,userNid,behaviorNid,timestamp FROM A where userNid = ANY (select Nid from C);

but i m getting error as foreign key constraints fails.
How can i solve this.
Thanks in advance.

Answer 1

Well this should check Nid in C for every foreign key in C and append to B.

INSERT INTO B(userid,behaviorid,userNid,behaviorNid,timestamp) SELECT
 userid,behaviorid,userNid,behaviorNid,timestamp FROM A LEFT JOIN C on A.foreignkey = C.Nid; 

Make sure you try it and comment, if not working
