SQL-382: Delete LegalBill via DeleteBill

This statement deletes the LegalBill entity identified by its LEGAL_BILL_SEQ_NUM key (with an UPDATE_NUM optimistic-concurrency check) from LEGAL_BILL, executed via IUnitOfWork.GetRepository<T>().Delete(...) from Services/SAIF.Services/Legal/Bills/BillSaveService.cs (L105) in BillSaveService.DeleteBill. The SQL below is inferred from this repository call and the NHibernate LegalBillMap mapping — it is not literal SQL present in source.

LINQ statement

Source: Services/SAIF.Services/Legal/Bills/BillSaveService.cs:105

_unitOfWork.GetRepository<BillData.LegalBill>()
    .Delete(legalBill);

Sample SQL

Inferred SQL: This SQL was inferred from the LINQ statement above and the NHibernate mappings. It is not concrete SQL from source code; NHibernate generates the executed statement at runtime, so aliases, column order, join syntax, and bind-parameter names may differ.

-- Inferred from LINQ (NHibernate mapping translation); not concrete SQL
DELETE FROM LEGAL_BILL
WHERE LEGAL_BILL_SEQ_NUM = :Id
  AND UPDATE_NUM = :oldVersion

Translation notes:

  • Version(x => x.UpdateNumber).Column("UPDATE_NUM") adds the old-version predicate to the DELETE.
  • HasMany(BillServices) and HasMany(BillStatusHistories) (key LEGAL_BILL_SEQ_NUM) are Cascade.AllDeleteOrphan() (lines 37-44) - child deletes cascade; not fabricated.
  • Entity loaded at line 100 (separate read).
