Hi - I keep stumbling on the same error:
An error occurred while trying to write to the entity “vehicle” [id=62d4f82a-d537-42fc-8e4e-c9d39f791ae1@4643, type=SG_VM_Vehicle (id=3470)] (data store: SG VM MySQL Data Store). Details: org.hibernate.exception.GenericJDBCException: could not insert: [SGVMVehicleDT2869]: java.sql.SQLException: Field 'vehicleid' doesn't have a default value Data: TypedValue[it=3470,v={<null>,White,White,3435643,1990,1,White,Sedan,5676545,2020-08-30,<null>,KPMG_SG,2020-07-31 05:24:28.1,,,<null>}]
I suspect the text in bold is the reason of the error but it remains enigmatic to me: can any one please tell me what I am doing wrong?
many thanks

Could it be that your forgot to set the auto-generate property for the field vehicleId. I assume that the DB table has been created via Appian.
HI Stefan, the auto-generate was checked. I have been following the remote develop training for the vehicle management app (did it three times in a row trying to fix the problem), the vehicle id is also a primary key and an integer......
Can you post a screenshot of the DB table configuration. Could it be that you always used the same name for the table. In that case Appian would not recreate it. In case your missed to check that box the first time, the configuration for that field would still be the same.
If this happens to me, I drop the table and have Appian recreate it. Checking the auto-generate box after initial table creation will not change field configuration.
What you say kind of resonates with me. see the attachments. I also noticed that the db has duplicated fields from the CDT.
I have uploaded two screenshots: one of the CDT and one of the db
Good. Now lets have a look at the tab "Structure".
what do you mean by tab structure?
This is how it should look like. Please drop the table and re-verify the data store to make Appian recreate it.
understood thank you. When you say drop the table, I should check all the fields and drop them...?
