{
    return Factory.GetRepository<MCOProvider>()
        .Query().Any(m => m.PoviderLocationId == providerLocationId && m.MCOId == mcoPlanId &&             //  (MCOId is MCO_PLAN_ID in the table)

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 * FROM (
  SELECT 1
  FROM MCO_PROVIDER MP
  WHERE MP.PROVIDER_LOCATION_SEQ_NUM = :providerLocationId
    AND MP.MCO_PLAN_ID = :mcoPlanId
    AND (
      (MP.EFF_DATE <= :serviceDate AND MP.EXP_DATE IS NULL)
      OR (MP.EFF_DATE <= :serviceDate AND MP.EXP_DATE >= :serviceDate)
    )
) WHERE ROWNUM <= 1

Translation notes: - Any(predicate) → row-limited existence probe. MCOId maps to MCO_PLAN_ID (MCOProviderMap.cs:13).
