SQL-002: AddressVerificationQueryProvider.GetAddressVerificationRequests¶

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

Classification¶

Database	Oracle*
Schema	[unqualified]**
Command type	N/A (ORM-generated)

LINQ statement¶

Source: Data/SAIF.Data/Queries/AddressVerification/AddressVerificationQueryProvider.cs:42. The repository is a class field initialised from Factory.GetRepository<AddressVerificationRequest>().Query() at Data/SAIF.Data/Queries/AddressVerification/AddressVerificationQueryProvider.cs:19.

return addressVerificationRepository.SingleOrDefault(x =>  x.Id == addressVerificationSeqNum
                                                           && x.VerifiedAddress  != null
                                                           && x.IsUnmatchedAddress == false
                                                           && x.IsMultipleMatch == false);

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
  AVR.ADDR_VERIFICATION_REQ_SEQ_NUM,
  AVR.UPDATE_NUM,
  AVR.REQUEST_DATE,
  AVR.STATUS_CODE,
  AVR.RESPONSE_DATE,
  AVR.ADDRESS_LINE1,
  AVR.ADDRESS_LINE2,
  AVR.CITY_NAME,
  AVR.STATE_CODE,
  AVR.ZIP_CODE,
  AVR.ZIP_CODE_EXT,
  AVR.UPDATE_DATE,
  AVR.UPDATE_USER,
  AVR.UNMATCHED_ADDRESS_FLAG,
  AVR.MULTIPLE_MATCH_FLAG,
  AVR.AUTO_UPDATE_BYPASS_DATE,
  AVR.VERIFIED_ADDRESS_SEQ_NUM
FROM ADDRESS_VERIFICATION_REQUEST AVR
WHERE AVR.ADDR_VERIFICATION_REQ_SEQ_NUM = :addressVerificationSeqNum
  AND AVR.VERIFIED_ADDRESS_SEQ_NUM IS NOT NULL
  AND AVR.UNMATCHED_ADDRESS_FLAG = 'N'
  AND AVR.MULTIPLE_MATCH_FLAG = 'N'
-- NHibernate expects at most one row

Translation notes: - x.VerifiedAddress != null is an FK null check, so it resolves to AVR.VERIFIED_ADDRESS_SEQ_NUM IS NOT NULL with no join; VERIFIED_ADDRESS is not accessed as a separate table. - == false on the YesNoType-mapped IsUnmatchedAddress and IsMultipleMatch properties becomes = 'N'.
