So in this case you need to add one more column for FC to show the relation . otherwise it will act like an independent entity.

Hi Sandeep ,

Thanks for the effort . adding to my concern , table 1's PK is the FK for table 2 . but table 3 doesn't have the FK field . but i need few columns from table 3 also (relating table 1 and 2 ) . ( table 3 and table 2 have few coloumn in common ) but they are not a KEY column .

Regards,
vetri

You need to think of establishing primary and foreign key relationship between these 3 tables then you can have the database view with the help of table join.
If you are new to RDBMS concepts as well, please check some references how to establish relationship between database entities and also how to create a database view.
Thanks

Hi Vetrivelk,

In this case you need to use Foreign Key concept in your tables. So here your Table 1 Primary key will act like a foreign key in rest of the table. And while fetching details in Appian from DB, I can suggest go with View in DB. I mean create a view in DB.

I hope this is the correct answer of your query.

Thanks,
Sandeep

Hi there,
Could you please clarify the requirement a little like the relationship between these 3 tables. If they have some referential integrity exists then you could create a database view joining them together and fetch the data from them.
Thanks
