Create an SQL AST select-statement for loading by unique key

Parameters:

loadable - The root Loadable

partsToSelect - Parts of the Loadable to select. Null/empty indicates to select the Loadable itself

restrictedPart - Part to base the where-clause restriction on

cachedDomainResult - DomainResult to be used. Null indicates to generate the DomainResult

loadQueryInfluencers - Any influencers (entity graph, fetch profile) to account for

lockOptions - Pessimistic lock options to apply

jdbcParameterConsumer - Consumer for all JdbcParameter references created

sessionFactory - The SessionFactory

createSelectBySingleArrayParameter

public static SelectStatement createSelectBySingleArrayParameter(Loadable loadable,
 ValuedModelPart restrictedPart,
 LoadQueryInfluencers influencers,
 LockOptions lockOptions,
 JdbcParameter jdbcArrayParameter,
 SessionFactoryImplementor sessionFactory)

Create a select-statement (SQL AST) for loading by multiple keys using a single SQL ARRAY parameter

Create an SQL AST select-statement based on matching one-or-more keys

Parameters:

loadable - The root Loadable

partsToSelect - Parts of the Loadable to select. Null/empty indicates to select the Loadable itself

restrictedPart - Part to base the where-clause restriction on

cachedDomainResult - DomainResult to be used. Null indicates to generate the DomainResult

numberOfKeysToLoad - How many keys should be accounted for in the where-clause restriction?

loadQueryInfluencers - Any influencers (entity graph, fetch profile) to account for

lockOptions - Pessimistic lock options to apply

jdbcParameterConsumer - Consumer for all JdbcParameter references created

sessionFactory - The SessionFactory
