Parameters¶

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

LINQ statement¶

Source: Data/SAIF.Data/Queries/Policies/PolicyQueryProvider.cs:37-39.

public PolicyTeamFunction GetPolicyTeamFunction(long policyNumber, string teamFunctionCode)
{
    return Factory.GetRepository<PolicyTeamFunction>().Query()
        .SingleOrDefault(t => t.PolicyNumber == policyNumber 
        && t.TeamFunctionCode == teamFunctionCode);
}

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
  PTF.POLICY_NUM,
  PTF.TEAM_FUNCTION_CODE,
  PTF.UPDATE_DATE,
  PTF.UPDATE_USER,
  PTF.USER_NAME
FROM POLICY_TEAM_FUNCTION PTF
WHERE PTF.POLICY_NUM = :policyNumber
  AND PTF.TEAM_FUNCTION_CODE = :teamFunctionCode
-- SingleOrDefault: NHibernate expects at most one row

Translation notes: - Composite key POLICY_NUM + TEAM_FUNCTION_CODE (PolicyTeamFunctionMap.cs:12-14). USER_NAME is the FK of the lazy WcisEmployee reference, which is not joined.
