Kai Zander ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-15525 ( https://hibernate.atlassian.net/browse/HHH-15525?atlOrigin=eyJpIjoiYWQ5NT... ) Re: Allow Global- and PersistentTemporaryTableStrategy to participate in hbm2ddl ( https://hibernate.atlassian.net/browse/HHH-15525?atlOrigin=eyJpIjoiYWQ5NT... ) Actually, when running against Oracle ( org.hibernate.dialect.OracleDialect ), Hibernate still attempts to create the temporary tables at application start. These statements then fail quietly (no exceptions are being thrown/logged): 2022-10-06T16:25:05.281Z INFO o.hibernate.jpa.internal.util.LogHelper : HHH000204: Processing PersistenceUnitInfo [name: default] 2022-10-06T16:25:05.307Z INFO org.hibernate.Version : HHH000412: Hibernate ORM core version 6.1.4.Final 2022-10-06T16:25:05.402Z WARN org.hibernate.orm.deprecation : HHH90000021: Encountered deprecated setting [javax.persistence.sharedCache.mode], use [jakarta.persistence.sharedCache.mode] instead 2022-10-06T16:25:05.521Z INFO SQL dialect : HHH000400: Using dialect: org.hibernate.dialect.OracleDialect 2022-10-06T16:25:06.338Z DEBUG org.hibernate.SQL : create global temporary table OWNER.HTE_tab_data(id number(19,0), col1 varchar2(255 char), col2 varchar2(255 char), col3 varchar2(255 char), rn_ number(10,0) not null, primary key (rn_)) on commit delete rows 2022-10-06T16:25:06.397Z DEBUG org.hibernate.SQL : create global temporary table OWNER.HTE_tab_data_staging(id number(19,0), col1 varchar2(255 char), col2 varchar2(255 char), col3 varchar2(255 char), rn_ number(10,0) not null, primary key (rn_)) on commit delete rows 2022-10-06T16:25:07.173Z INFO o.h.e.t.j.p.i.JtaPlatformInitiator : HHH000490: Using JtaPlatform implementation: [org.hibernate.engine.transaction.jta.platform.internal.NoJtaPlatform] 2022-10-06T16:25:07.180Z INFO j.LocalContainerEntityManagerFactoryBean : Initialized JPA EntityManagerFactory for persistence unit 'default' However, this is not that critical to us, because at runtime, Hibernate does not attempt to use these tables.
