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 MIN(ES.BILL_SERVICE_DATE)
FROM EBILL_SERVICE ES
WHERE ES.EBILL_SEQ_NUM = :ebillId
Translation notes: - Direct translation: an equality predicate on mapped columns. No navigation, joins or in-memory operators.
