SQL-298: PolicyOutputDocumentExtensions.GeneratePacket

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

Classification

Field	Value
SQL ID	SQL-298
Operation type	Read
Execution method	ORM (NHibernate LINQ)
Database	Oracle*
Schema	[unqualified]**

Parameters

Parameter	Direction	Type	Max length	Description
primaryType	Input	string	N/A	Method argument of PolicyOutputDocumentExtensions.GeneratePacket bound into the ORM expression; NHibernate generates the bind variable at runtime
secondaryType	Input	string	N/A	Method argument of PolicyOutputDocumentExtensions.GeneratePacket bound into the ORM expression; NHibernate generates the bind variable at runtime
packetCount	Input	int	N/A	Method argument of PolicyOutputDocumentExtensions.GeneratePacket bound into the ORM expression; NHibernate generates the bind variable at runtime
nonPacketDocCount	Input	int	N/A	Method argument of PolicyOutputDocumentExtensions.GeneratePacket bound into the ORM expression; NHibernate generates the bind variable at runtime

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.

Translation notes: - Not accessed: output_doc_image_type_xref (old page) — HasManyToMany(ImageDocumentTypes) join table, lazy and never navigated. image_document_type_code, output_document_category_code, output_doc_notify_text_code — FK columns only. - types is a deferred IQueryable; (a) is executed twice — by ForEach (line 1625) and by Select(...).ToList() (line 1637). - If primaryType/secondaryType is null, NHibernate renders x.Code != null as code IS NOT NULL (C# null semantics).
