Hello there,

Could you please give us some more information?

  • What is your TDM version?
  • What kind of models are you comparing? How was the “faulty” SQL Server 2008 model created? (reversed engineered model / model created in older versions of TDM / model created in your current version of TDM?)
  • Could you send us screenshot of the comparison screen in Model Compare/Merge/Update wizard? It shows the differences between two models.
    Thank you for your cooperation!

Regards,

Lukas

Hi, follow the requested information:

  1. TDM version: 5.4.5.3 beta
  2. Using “update model from database”, comparing a model created on TDM to a DDL generated Database. Everything created on TDM same version.
  3. On TDM1.png you can see, for exemple, there’s no changes on PROPOSAL entity. Even though, the model is updated with a new doubled Index. That happens with all Entities (TDM2.png).
  4. To fix, I have to enter in all tables PK properties, remove PK checkbox, apply and check it again.

The DDL script is generated with double index references:

**CREATE INDEX [IX_Relationship40] ON [dbo].[PROPOSAL] ([ID_CHANNEL],[ID_CHANNEL])
ON [PRIMARY]
go

CREATE INDEX [IX_Relationship41] ON [dbo].[PROPOSAL] ([ID_OPERATION],[ID_OPERATION])
ON [PRIMARY]
go

CREATE INDEX [IX_Relationship42] ON [dbo].[PROPOSAL] ([ID_PROPOSAL_SCORE_RESULT],[ID_PROPOSAL_SCORE_RESULT])
ON [PRIMARY]
go**

Hello again,

We’ve reproduced the issue, it is a bug that affects your beta version - 5.4.5.3. If you have a model with a non-identifying relationship and a child entity with a FK index, the index attribute(s) will be duplicated after Model Update, even when no differences are found.

The issue has been already fixed in the upcoming TDM 5.4 full version so you can either wait until its release, or try doing the same action in TDM 5.3, where the issue doesn’t seem to be present.

Thank you for your report!

Regards,

Lukas
