SQL-285: PolicyExtensions.GenerateRelationshipPolicies¶

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

Classification¶

Field	Value
SQL ID	SQL-285
Operation type	Read
Execution method	ORM (NHibernate LINQ)
Database	Oracle*
Schema	[unqualified]**
Command type	N/A (ORM-generated)
Business object	`PolicyExtensions`
Criteria property	N/A — ORM
Lifecycle method	`GenerateRelationshipPolicies`

Parameters¶

Parameter	Direction	Type	Max length	Description
`relationship`	Input	string	N/A	Method argument of `PolicyExtensions.GenerateRelationshipPolicies` bound into the ORM expression; NHibernate generates the bind variable at runtime

Tables¶

Table	Access	Columns used
POLICY_RELATIONSHIP_CODE	SELECT ×1 (hypothetical)	CODE, CODE_DESCR

LINQ statement¶

Source: Data/SAIF.Data/TestRepository/RepositoryExtensions/PolicyExtensions.cs:133.

// Data/SAIF.Data/TestRepository/RepositoryExtensions/PolicyExtensions.cs:133
var rel = uow.GetRepository<PolicyRelationshipCode>().Query().SingleOrDefault(x => x.Code == relationship.ToUpper());

Sample SQL¶

Test double — no runtime SQL. This statement executes against TestUnitOfWork/TestRepository<T> (in-memory, List<TEntity>-backed test doubles in SAIF.Framework.Core); no NHibernate session is opened and no SQL is issued at runtime. The SQL below is the hypothetical statement the same expression would produce against a real NHibernate IUnitOfWork using the in-repo mappings, shown to document the mapping shape only — no database table is accessed when this code runs.

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
-- line 133
SELECT
  PRC.CODE,
  PRC.CODE_DESCR
FROM POLICY_RELATIONSHIP_CODE PRC
WHERE PRC.CODE = :p0
-- SingleOrDefault

Translation notes: - String constants (and captured values) are bound as parameters by NHibernate (:p0); the literal is shown in the trailing comment. - relationship.ToUpper() does not depend on the lambda parameter; it is evaluated in memory and bound as :p0.
