    Hi @Kimbrough, Gerrold ,

    The DELETE statement conflicted with the REFERENCE constraint "B_INDEX_LEXICON_EXTENSION_B_INDEX_LEXICON_FK".

    Please refer to the following methods and links:
    1.We can drop and re-add the constraint with the ON DELETE CASCADE.
    2. We can disable constraints on the table. This usually not a great idea as you can end up with a bad data condition if you're messing with data that relates to other tables, but not know the full extent of your schema and it may suit your purposes.

    The DELETE statement conflicted with the REFERENCE constraint

    Commonly used SQL Server Constraints: FOREIGN KEY, CHECK and DEFAULT

    Best Regards,
