We're using Oracle 10g and are receing the following error message:

[SSI Error: STD208 - Oracle SQL Error: ORA-02291: integrity constraint (BLUE.ARRFOREIGN) violated - parent key not found ORA-06512: at "BLUE.PLISTREFADDRESSESADMIN61114", line 6 ]

The error occurs when we go to add a new entry to the refrences table. From the error I suspect a parent key doesnt exist to match the refrence table's foregin key? The problem Im having, even with the use of Oracle's fabulous Sql Developer IDE for Windows is Im unable to see the table relationships to confirm any of this. I have no clue what table this reference table is related to or even able to see those very constraint items listed anywhere.

Can someone please help me through this issue.

Thank you.

UPDATE: I performed an EDIT TABLE and checked all the tabs and found no Foreign Key listed however a single primary key was defined on the ID column

Well, if Oracle says that the referential integrity constraint is violated, I guess you should believe it Smile

Such a query might show which table is involved into the parent-child relationship:
SELECT c.table_name, o.column_name
 WHERE c.constraint_name = (SELECT c1.r_constraint_name
                              FROM USER_CONSTRAINTS c1
                             WHERE c1.constraint_name = 'ARRFOREIGN')
   AND o.constraint_name = c.constraint_name;

To see the RI (and all other) constraints in SQL Developer:
1) Go to the connections panel and expand the schema you wish to look in.
2) Expand Tables.
3) Click on the table you wish to look at. A new tab will appear on the right hand half of the screen containing the details of this table
4) Click on the the Constraints tab on this new tables Tab
This will show you all the constraints currently defined on this table.

not trying to be rude... Do you not have access to plain jane sqlplus? do some simple querying and forget all those fancy "gui" tools. Please excuse me if I assume you don't know the following:

desc dba_constraints (or all or user)
desc dba_cons_columns "

The error message gives the constraint name being violated.

Good luck Kevin
