SQL-279: Retrieve ProviderLocation

This statement retrieves a single ProviderLocation by its identifier via NHibernate LINQ, executed once per registered agent or process server in a preceding list, to resolve the associated provider location in SubpoenaService.ListOfRegisteredAgents and SubpoenaService.ListOfProcessServers, executed from Services/SAIF.Services/Legal/Subpoenas/SubpoenaService.cs (L359, L393).

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
    PL.PROVIDER_LOCATION_SEQ_NUM,
    PL.UPDATE_NUM,
    PL.BUSINESS_NAME,
    PL.PAYEE_NAME,
    PL.PRIMARY_LOCATION_FLAG,
    PL.BUSINESS_FLAG,
    PL.PHONE_AREA_CODE,
    PL.PHONE_NUM,
    PL.PHONE_NUM_EXT,
    PL.TOLL_FREE_PHONE_NUM,
    PL.FAX_NUM,
    PL.LAST_NAME,
    PL.FIRST_NAME,
    PL.MIDDLE_NAME,
    PL.PROVIDER_TYPE_CODE,
    PL.PROVIDER_SEQ_NUM
  FROM PROVIDER_LOCATION PL
  WHERE PL.PROVIDER_LOCATION_SEQ_NUM = :LocationId
)
WHERE ROWNUM <= 1

Translation notes: - Executes once per element of the preceding list (N+1 pattern). - First/FirstOrDefault → Oracle10 dialect row limit SELECT * FROM (...) WHERE ROWNUM <= 1 (no ORDER BY, so the row returned is not deterministic if more than one matches). - HasMany collections (Addresses, Identities, ProviderServices) are lazy; References(ProviderType)/References(Provider) contribute FK columns only.
