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

Classification¶

Field	Value
SQL ID	SQL-171
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	`GetLocationContacts`

Parameters¶

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

Tables¶

Table	Access	Columns used
CONTACT	SELECT	LOC_SEQ_NUM, CONTACT_TYPE_CODE, CONTACT_EFF_DATE, CONTACT_EXP_DATE, BUS_SEQ_NUM, CONTACT_FIRST_NAME, CONTACT_INITIAL, CONTACT_LAST_NAME, CONTACT_TITLE, CONTACT_PHONE, CONTACT_PHONE_EXT, EMAIL_ADDR, CELL_PHONE, CREATE_USER, CREATE_DATE, UPDATE_USER, UPDATE_DATE

LINQ statement¶

Source: Data/SAIF.Data/Queries/Locations/LocationQueryProvider.cs:49-50.

public IQueryable<Contact> GetLocationContacts(long locationId)
{
    return Factory.GetRepository<Contact>()
        .Query().Where(x => x.Id == locationId && x.ExpirationDate == null).OrderBy(x => x.ContactType);
}

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
  C.LOC_SEQ_NUM,
  C.CONTACT_TYPE_CODE,
  C.CONTACT_EFF_DATE,
  C.CONTACT_EXP_DATE,
  C.BUS_SEQ_NUM,
  C.CONTACT_FIRST_NAME,
  C.CONTACT_INITIAL,
  C.CONTACT_LAST_NAME,
  C.CONTACT_TITLE,
  C.CONTACT_PHONE,
  C.CONTACT_PHONE_EXT,
  C.EMAIL_ADDR,
  C.CELL_PHONE,
  C.CREATE_USER,
  C.CREATE_DATE,
  C.UPDATE_USER,
  C.UPDATE_DATE
FROM CONTACT C
WHERE C.LOC_SEQ_NUM = :locationId
  AND C.CONTACT_EXP_DATE IS NULL
ORDER BY C.CONTACT_TYPE_CODE

Translation notes: - ContactMap uses a composite key: LOC_SEQ_NUM (the Id property), CONTACT_TYPE_CODE (ContactType), and CONTACT_EFF_DATE (EffectiveDate). - The method returns IQueryable<Contact>; execution is deferred to the caller.
