HSQL: Creating index if not existing

由 好久不见. 提交于 2019-12-09 17:27:34

How do I run a memory-only HSQLDB server? I ran the following but get no clue. java -cp ../lib/hsqldb.jar org.hsqldb.Server -? 回答1: use java -cp .\hsqldb-1.8.0.10.jar org.hsqldb.Server -database.0 mem:aname In memory mode is specified by the connection url - so if you want, you can just have a server.properties

Auto-incrementation with HSQLDB (2.2.8) + DDLUtils

由 我只是一个虾纸丫 提交于 2019-12-08 06:35:49
问题 I want to use HSQLDB as an embedded database but am having trouble getting it to auto-increment . As far as I understand, [CALL] IDENTITY() can be used to get the last primary key value. However, experiments through both iBatis and HSQLDB's DatabaseManagerSwing continually return a 0 value. How can I get auto-incrementation to work with HSQLDB? Edit: I didn't mention that I'm using DDLUtils to autogenerate tables. The following does not suit HSQLDB: <?xml version="1.0"?> <!DOCTYPE database
