Hey guys!


I have an Entity imported from an External Database, that has no Identifier.

I want to create and use a Combo Box, based on that Entity. 

Is it possible? If yes, how? If no, is there a workaround?


Thanks!

Hi Marios Tofarides,


You need to define an identifier entity column while creating that entity and use that column as the identifier for Combo Box.


You can use a combo box without the identifier just specify a colum from the entity in variable property of combo box. But by doing this you will see a warning for the combo box.

Hey there,

The Entity is an external database one. Can I create an Identifier for that?


Thanks!

Thanks!

Yes you can while converting the external database to entity by using integration studio and giving the column as auto number.


Solution

What if I want one of the columns in the Entity to be the identifier?

Just right click the column and set it as an identifier.

Hi Marios, 

How did you create this entity without an Identifier, and why? 

Usually we just create an Id comlumn autonumber. When doing bootstrap, the IDs will be created automatically by the database. 

And it is a good practice to have this 'meaningless' Identifier. 

OK, thanks a lot!
