I am trying to figure out H2's support for temporary tables in order to properly utilize them from Hibernate's H2Dialect. But I am running into some questions:
1) First, does creating a temporary table cause an implicit transaction commit? The H2 driver reports that DDL does cause an implicit commit (DatabaseMetaData#dataDefinitionCausesTransactionCommit). My question is whether that is true of temporary objects as well? Does LOCAL/ GLOBAL matter here? 2) Based on WhatMadeSense, I tried to have Hibernate use "create cached local temporary table if not exists" as the command (cached because I am unsure how many rows might be added and the docs implied that memory should not be used if the table is "too large", whatever that means). However, because of DatabaseMetaData#dataDefinitionCausesTransactionCommit returning true right now Hibernate is issuing this in a separate connection. The odd part is that the "main connection" is able to see it. Am I missing something about "local" as pertains to temp tables in H2? -- You received this message because you are subscribed to the Google Groups "H2 Database" group.
