SQL-168: LocationQueryProvider.GetPolicyLocations¶

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

Classification¶

Field	Value
SQL ID	SQL-168
Operation type	Read
Execution method	ORM (NHibernate LINQ)
Database	Oracle*
Schema	[unqualified]**
Command type	N/A (ORM-generated)
Business object	`LocationQueryProvider`
Criteria property	N/A — ORM
Lifecycle method	`GetPolicyLocations`

Parameters¶

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

LINQ statement¶

Source: Data/SAIF.Data/Queries/Locations/LocationQueryProvider.cs:25-28.

public IQueryable<Location> GetPolicyLocations(long policyNumber)
{
    return Factory.GetRepository<Location>()
        .Query()
        .Where(x => x.PolicyNum == policyNumber && x.ExpirationDate == null)
        .OrderBy(x => x.AddressLine1);
}

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
  L.LOC_SEQ_NUM,
  L.POLICY_NUM,
  L.BUS_SEQ_NUM,
  L.AGENT_NUM,
  L.PARENT_LOC_SEQ_NUM,
  L.LOC_EFF_DATE,
  L.LOC_EXP_DATE,
  L.LOCATION_CODE,
  L.LOCATION_NAME,
  L.LOC_ADDR1,
  L.LOC_ADDR2,
  L.LOC_CITY,
  L.LOC_COUNTRY,
  L.LOC_PHONE,
  L.LOC_PHONE_EXT,
  L.LOC_FAX,
  L.LOC_STATE,
  L.LOC_ZIP,
  L.LOC_ZIP4,
  L.SIC_CODE,
  L.PROVIDER_NUM,
  L.CREATE_USER,
  L.CREATE_DATE,
  L.UPDATE_USER,
  L.UPDATE_DATE,
  L.USPS_BARCODE,
  L.EMAIL_ADDR,
  L.EMPLOYEE_COUNT,
  L.LOC_ADDR3,
  L.PRIMARY_LOCATION_FLAG,
  L.CELL_PHONE,
  L.LOC_COUNTY
FROM LOCATION L
WHERE L.POLICY_NUM = :policyNumber
  AND L.LOC_EXP_DATE IS NULL
ORDER BY L.LOC_ADDR1

Translation notes: - The method returns IQueryable<Location> unmaterialized. The SQL runs when the caller enumerates it, and the caller may compose more operators first. - x.ExpirationDate == null → LOC_EXP_DATE IS NULL.
