VLD-0201:Table has more than one primary key

Question

hi
i'm working with OWB 9.2,I was imported the table from database,when i validating that it is giving message:
VLD-0201:Table has more than one primary key
vld-0209:Duplicate unique key i.e:cust_acc and SYS_C00435 detected.
Can i use this table and generate the mapping with out any errors?
Any help will be very generate.

Hi Ashok,
I'm quite curious how you managed to get a table with 2 PK's.
I tried it myself:
=======================================================
SQL>create table x(c1 number constraint pk1 primary key,c2 number constraint pk2 primary key, c3 date);
create table x(c1 number constraint pk1 primary key,c2 number constraint pk2 primary key, c3 date)
ERROR at line 1:
ORA-02260: table can have only one primary key
SQL>ed
Wrote file afiedt.buf
1* create table x(c1 number constraint uk1 unique,c2 number constraint uk2 unique, c3 date)
SQL>/
Table created.
=====================================================
As you can see, trying to create a table with more than 1 PK is impossible. With Unique Key, that IS possible (see second example).
I don't expect mappings to function properly with such an error message.
Is it possible for you to drop the table in the database, correct the definition of the table in OWB and then deploy that corrected version to the database?
If on the other hand the table on the database is correct (i.e. has only one PK) then the import into OWB obviously did not go well and I'd suggest you drop the imported definition and try to import it again.
