Synchronize Database Errors: Column names in each table must be unique

(0) ShareShare
ReportReport
Posted on by Jonatan Torino 35

Hi everybody, first to all, i apologize for my bad english


I have this error when synchonize DB, after data upgrade in place.

Column names in each table must be unique. Column name 'FIELDNAME_B' in table 'TABLE_A' is specified more than once.


It's happening with this single TABLE_A, this is a base table, but the FIELDNAME_B belong to TABLE_B an extended table from TABLE_A. This FIELDNAME_B exists for TABLE_A on SQL.

i try to looking on SqlDictionary and ModelElement, but i missing something, where could be the error?

Any help is appreciated,

Jonatan

    Check if FIELDNAME_B isn't defined in another table (in addition to TABLE_B) in the same table hierarchy. If it isn't, verify that there are no ID conflicts.

    Check the fieldId on Field_B properties and also in value of FieldId in SQLDictionary table. Sometimes they got mismatched

    I have an ID fix class/job, you may attempt to run that and see if it resolves the issue within SQL Dictionary.

    It should work as long as you do not have an actual conflict in your AOT via using the same field at different levels of the table type hierarchy.

    I resolved it. when I checked, There was no data in "FIELDNAME_B". I manually deleted the field from the database. Ran the Retail Management Utility, the database got upgraded and the column "FIELDNAME_B" was recreated.
