I am trying to use UCanAccess to query a MS Access .accdb file. Everything works great, except when I query multi-value fields. For example those that have entries in the Row Source of a table field's Lookup tab in design view in MS Access. My code crashes when I try to output the result: ResultSet rslt = stmt.executeQuery("SELECT [singleValue], [multiValue] FROM [TableName];"); int count = 0; while (rslt.next()) System.out.println(count++ + "\t" + rslt.getString(1) + "\t" + rslt.getString(2)); The ResultSet is returned fine, and the singleValue prints fine, but the following error is thrown

Can I use H2, HSQLDB, or any other embedded database, with a database from an InputStream instead of a file? I'm planning to use AssetManager.open() on Android, which can return an InputStream in random access mode. H2 supports a pluggable file system that allows you to access read-only databases in a zip or jar files . However, there is currently no file system implementation for the AssetManager . It should be relatively easy to implement it. The best starting point is probably FileSystemZip and FileObjectZip . Most databases need random access to underlying files so an InputStream will not

How do I use LIKE % in Hibernate. I want to use a SQL with LIKE % in my hbm.xml file. I have 2 queries which I am consolidating to 1. The query looks like this: select * from PAY_GROUP_VW where CASE_SID=? AND CASE_TLE like %?% I also tried %?% . I have used like clause without % and it works. But % does not work. Wrapped exception: org.springframework.dao.InvalidDataAccessResourceUsageException: could not execute query; nested exception is org.hibernate.exception.SQLGrammarException: could not execute query at org.springframework.orm.hibernate3.SessionFactoryUtils

I am using HSQL ver 1.7. There is a part where I have a HQL like the following String hql = "from ProductInv prodInv where prodInv.product.id in (:prodList)"; prodList contains list of product ids and the above hql is to get product inventories of the required product ids in prodList. This hql is translated to a native sql query with "cross join". When this works against my actual db2, it works fine. But my unit tests based on HSQL fails. It says "cross join" is not a recognized keyword. You need to upgrade to one of the latest versions of HSQLDB (HSQLDB Versions 1.7.x are at least 7 years old

Is it possible to limit the number of rows that are updated using Hibernate/HQL? For instance: Query q = em.createQuery("UPDATE MyObj o Set o.prop = :prop"); q.setParameter("prop", "foo"); q.setMaxResults(myLimit); int res = q.executeUpdate(); if (res > myLimit) { // This is entering here and I don't want it to! } I've been Googling around and such, and I am trying to use HQL so that I can do some unit tests using HSQL DB in memory dbs, as well as using MySql in deployment. MySql supports the Limit clause on Update statements, but HSQL does not, and doing an UPDATE with an inner select in HSQL
