> Teiid throws an error in case it tries to follow an odata Navigation property. I tried this by using $expand and also by directly following a path. Two examples are shown below. My $metaddata.xml file is attached, and also a single record from the Account table in which the relevant comparison seems to happen. the uuidUser property you can find here.
> I do not understand the error message. What is not clear to me is the assignment which is mentioned there g1.uuidUser = g0.fkProfile 
> Just for your awareness, uuidUser and fkProfile are different columns of different types that should not be compared in anyway. Maybe this is a hint what is going wrong. I would the relevant NavigationProperty expect to be
> <NavigationProperty Name="fkProfileInProfile" Type="my_nutri_diary.Account" Nullable="false">
> <ReferentialConstraint Property="fkProfile" ReferencedProperty="idProfile"/>
> Here are two example queries which fail with the same error
> http://localhost:8080/odata4/vdb/my_nutri_diary/Profile(38)?$expand=fkProfileInProfile
> http://localhost:8080/odata4/vdb/my_nutri_diary/Profile(38)/fkProfileInProfile
> <error xmlns="http://docs.oasis-open.org/odata/ns/metadata">
> <code>TEIID31172</code>
> <message>
> TEIID31172 Could not resolve expressions being compared to a common type excluding character conversions: g1.uuidUser = g0.fkProfile
> </message>
> </error>
> ----------------------------
> Update 9.1.19: I need to to add here, that there might be a second bug involved into the observation. It seems, that the error is due to type comparisons. As there was a comparison with Account.uuuiUser in the error message and as my table Account just holds a one to one mapping between uuids and integers which represent database internal IDs, I switched the primary key in the Account table from uuidUser to idProfile in hope to circumvent the bug.  
> So my new observation is, when I disable row constraints in which I must have a comparison against uuidUser in the form "Profile.fkProfile in (SELECT Account.idProfile FROM Account WHERE Account.uuidUser = LEFT(user(), 36))" and switch hte primary key as mention previously, than I can follow the navigation property. However, as soon as I enable row constraints again I get a similar error message as before:
> <error xmlns="http://docs.oasis-open.org/odata/ns/metadata">
> <code>TEIID31172</code>
> <message>
> TEIID31172 Could not resolve expressions being compared to a common type excluding character conversions: g1.uuidUser = g0.fkProfile
> </message>
> </error>
> As I am not sure if the issue derives from the same place in code, I thought I should add this here.
