SQL ID	SQL-064
Operation type	Read
Execution method	ORM (NHibernate LINQ)
Database	Oracle*
Schema	[unqualified]**
Command type	N/A (ORM-generated)
Business object	`ClaimQueryProvider`
Criteria property	N/A — ORM
Lifecycle method	`GetClaimLegalRepresentative`

Parameters¶

Parameter	Direction	Type	Max length	Description
`claimId`	Input	long	N/A	Method argument of `ClaimQueryProvider.GetClaimLegalRepresentative` bound into the ORM expression; NHibernate generates the bind variable at runtime

Table	Access	Columns used
CL_CLAIM_LEGAL_REPRESENTATIVE	SELECT (outer query and scalar subquery)	CLAIM_ID, EFF_DATE, UPDATE_NUM, EXP_DATE, UPDATE_DATE, UPDATE_USER, LEGAL_REP_END_REASON_CODE, PROVIDER_LOCATION_SEQ_NUM, PARENT_PROVIDER_LOC_SEQ_NUM

LINQ statement¶

Source: Data/SAIF.Data/Queries/Claims/ClaimQueryProvider.cs:303-307.

// Data/SAIF.Data/Queries/Claims/ClaimQueryProvider.cs:303
var repo = Factory.GetRepository<ClaimLegalRepresentative>();
return repo.Query().Where(x => x.ClaimId == claimId)
           .SingleOrDefault(x => x.EffectiveDate == repo.Query()
                                             .Where(w => w.ClaimId == claimId)
                                             .Max(m => m.EffectiveDate));

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
  CCLR.CLAIM_ID,
  CCLR.EFF_DATE,
  CCLR.UPDATE_NUM,
  CCLR.EXP_DATE,
  CCLR.UPDATE_DATE,
  CCLR.UPDATE_USER,
  CCLR.LEGAL_REP_END_REASON_CODE,
  CCLR.PROVIDER_LOCATION_SEQ_NUM,
  CCLR.PARENT_PROVIDER_LOC_SEQ_NUM
FROM CL_CLAIM_LEGAL_REPRESENTATIVE CCLR
WHERE CCLR.CLAIM_ID = :claimId
  AND CCLR.EFF_DATE = (
    SELECT MAX(CCLR2.EFF_DATE)
    FROM CL_CLAIM_LEGAL_REPRESENTATIVE CCLR2
    WHERE CCLR2.CLAIM_ID = :claimId
  )
-- NHibernate expects at most one row

Translation notes: - (CLAIM_ID, EFF_DATE) is the composite key, so at most one row matches. - The Provider, ParentProvider and LegalRepresentativeEndReason references are not navigated; only their FK columns are selected, so those tables are not accessed as separate joins.
