Apparently some Eclipse library APIs have changed since then. When a tool is up and running, you can connect to a database may be a new database and use SQL commands to access and modify the data. These objects can be reused, but if they are not needed after performing the operations, they should be closed. A database has many optional properties, described in the System Management chapter. The main drawback is that it is not possible by default to connect to the database from outside your application. A server can provide connections to more than one database.

Hsqlddb can specify most of these properties on the URL or in the connection properties for the first connection that creates the database. Connection object that is returned to access the data.

All these objects belong to the connection that returned them and are closed when the connection is closed. In most server modes, the server can serve an unlimited number of databases that are specified at the time of running the server, or optionally, as a connection request is received.

HyperSQL supports three live switchable transaction control models, including fully multi threaded MVCC, and is suitable for high performance transaction processing applications.



But if a second connection is made to an open database, using a path and name that differs only in case, then the connection is made to the existing open database. After this, creation of connections and calls to JDBC methods of the connections execute as if they are part of the Java application that is making the calls.

A Sever mode is also the preferred mode of running the database during development. Note that only one Java process at a time can make in-process connections to a given file: A command similar to those eclupse for running tools and described hsqlvb is used for running the server. Apparently some Eclipse library APIs have changed since then. HyperSQL is the only open-source relational database management eclipsd with a high performance dedicated lob storage system, suitable for gigabytes of lob data.

WorkbenchWindow can not be cast to org. Statement object is used to execute queries and data change statements. A database has many optional properties, described in the System Management chapter.

At the time of the next startup, all such files will be renamed or deleted by the database engine. The properties file contains a few settings about the database. The Servlet mode can serve multiple databases. Sign up using Facebook. Server modes provide the maximum accessibility.

PreparedStatementthe engine keeps the compiled SQL statement for reuse, jsqldb the java. Note When the engine closes the database at a shutdown, it creates temporary files with the extension. Statement can be reused to execute a different statement each time.


HyperSQL provides two optional security mechanisms.

Chapter 1. Running and Using HyperSQL

A Java resource is stored in a compressed format and is decompressed in memory when it is used. It hsqleb used when a servlet engine or application server such as Tomcat or Resin provides access to the database.

An additional jar, sqltool. This guide covers the database engine features, SQL syntax and different modes of operation.

Installing and configuring HSQLDB Database

The data file contains the data for cached tables and the backup file is a compressed backup of the last known consistent state of the data file. This method of access is used when the computer hosting the database server is restricted to the HTTP protocol.

In this situation, connections to a catalog are usually made in-processor using a separate Server. The public name hides the file names from users.

The exception is the default SA user, which is not case-sensitive.
