SQL-172: LocationQueryProvider.GetPolcyClaimLocationWithDefault¶

This statement is a read operation invoked through ORM (NHibernate LINQ). Executed by LocationQueryProvider.GetPolcyClaimLocationWithDefault.

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
    L.LOC_SEQ_NUM,

    AND L.LOC_EXP_DATE IS NULL
    AND L.LOCATION_CODE = 'CLM'
    AND (L.LOC_EXP_DATE IS NULL OR L.LOC_EXP_DATE < :nowDate)
  ORDER BY TRUNC(L.LOC_EFF_DATE) DESC
) WHERE ROWNUM <= 1
-- If no row: falls back to GetPolicyMailingLocation(policyNumber) — see SQL-170

Translation notes: - o.EffectiveDate.Date → Oracle TRUNC(L.LOC_EFF_DATE) (the NHibernate Oracle dialect maps DateTime.Date to trunc). - DateTime.Now.Date contains no lambda parameter, so NHibernate evaluates it client-side and binds it as :nowDate. - !x.ExpirationDate.HasValue → IS NULL. The OR-group is redundant given the earlier LOC_EXP_DATE IS NULL but is kept as authored. - A second statement may run (SQL-170) when the first returns nothing.
