This feature is useful for running tests, where it may not be practical to shutdown the database after each test. PreparedStatementthe engine keeps the compiled SQL statement for reuse, until the java.

This feature has a side effect that can confuse new users. To run an HTTP server, replace the main class for the server in the example command line above with the following:. In the example below, the database is called jbdc. The database file hslq format can be specified using forward slashes in Windows hosts as well as Linux hosts. Direct downloads from SourceForge exceed 2, copies, with hundreds of millions of copies distributed as part of other software packages.

These modes allow a high degree of compatibility with several other database systems which use non-standard SQL syntax. HyperSQL is the only open-source relational database management system with jdhc high performance dedicated lob storage system, suitable for gigabytes of lob data.

Versions released in recent years have enhanced reliability and performance.

Tools can use command line arguments. In general, JDBC is used for all access to databases.
