Lifecycle method	`GetPreferenceByPolicyNumber, GetPreferences, HasPreference`

Parameters¶

Parameter	Direction	Type	Max length	Description
`policyNumberList`	Input	**	N/A	`a.PolicyNumber` IN (policyNumberList) (`Contains`) → column POLICY_NUMBER
`policyNumber`	Input	**	N/A	`p.PolicyNumber == policyNumber` → column POLICY_NUMBER

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
-- Services/SAIF.Services/Policies/Certificates/CertificatePreferenceService.cs:65
SELECT
  CP.POLICY_NUMBER,
  CP.DELIVERY_METHOD_CODE,
  CP.RENEWAL_NOTIFICATION_CODE,
  CP.EMAIL_ADDRESS,
  CP.FAX_NUMBER,
  CP.UPDATE_USER,
  CP.UPDATE_DATE,
  CP.CREATE_USER,
  CP.CREATE_DATE
FROM CERTIFICATE_PREFERENCE CP
WHERE CP.POLICY_NUMBER IN (:policyNumberList)

-- Services/SAIF.Services/Policies/Certificates/CertificatePreferenceService.cs:113
SELECT COUNT(*)
FROM CERTIFICATE_PREFERENCE CP
WHERE CP.POLICY_NUMBER = :policyNumber

-- Services/SAIF.Services/Policies/Certificates/CertificatePreferenceService.cs:127
SELECT
  CP.POLICY_NUMBER,
  CP.DELIVERY_METHOD_CODE,
  CP.RENEWAL_NOTIFICATION_CODE,
  CP.EMAIL_ADDRESS,
  CP.FAX_NUMBER,
  CP.UPDATE_USER,
  CP.UPDATE_DATE,
  CP.CREATE_USER,
  CP.CREATE_DATE
FROM CERTIFICATE_PREFERENCE CP
WHERE CP.POLICY_NUMBER = :policyNumber
-- NHibernate expects at most one row

Translation notes: - L65-66 is materialized by Mapper.Map (L68). - L112-115: Count(...) -> SELECT COUNT(*); the > 0 comparison runs in memory.
