// Data/SAIF.Data/Queries/Claims/Ebilling/EbillDocumentQueryProvider.cs:16

return _repository.Single(doc => doc.Id == documentId);

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
SELECT
  ED.EBILL_DOCUMENT_SEQ_NUM,
  ED.UPDATE_NUM,
  ED.EBILL_DOCUMENT_SUB_NUM,
  ED.EBILL_DOCUMENT_CONTROL_NUM,
  ED.IMAGE_SEQ_NUM,
  ED.UPDATE_USER,
  ED.UPDATE_DATE,
  ED.EBILL_SEQ_NUM,
  ED.EBILL_DOCUMENT_TYPE_CODE
FROM EBILL_DOCUMENT ED
WHERE ED.EBILL_DOCUMENT_SEQ_NUM = :documentId
-- NHibernate expects at most one row

Translation notes:

Single() throws when no row, or more than one row, is returned.
