SQL ODBC driver can be used Multi version concurrency Additional Features. Disk based or in memory databases and tables, read only database support, temporary tables Transaction support read committed, 2 phase commit Multiple connections, table level locking Cost based optimizer, using a genetic algorithm for complex queries, zero administration Scrollable and updatable result set support, large result set, external result sorting, functions can return a result set Encrypted database AES, SHA 2. SSL SQL Support. Support for multiple schemas, information schema Referential integrity foreign key constraints with cascade, check constraints Inner and outer joins, subqueries, read only views and inline views Triggers and Java functions stored procedures Many built in functions, including XML and lossless data compression Wide range of data types including large objects BLOBCLOB and arrays Sequence and autoincrement columns, computed columns can be used for function based indexes ORDER BY, GROUP BY, HAVING, UNION, LIMIT, TOPCollation support, including support for the ICU4. J library Support for users and roles Compatibility modes for IBM DB2, Apache Derby, HSQLDB, MS SQL Server, My. SQL, Oracle, and Postgre. SQL. Security Features. Includes a solution for the SQL injection problem User password authentication uses SHA 2. For server mode connections, user passwords are never transmitted in plain text over the network even when using insecure connections this only applies to the TCP server and not to the H2 Console however it also doesnt apply if you set the password in the database URL All database files including script files that can be used to backup data can be encrypted using the AES 1. The remote JDBC driver supports TCPIP connections over TLS The built in web server supports connections over TLS Passwords can be sent to the database using char arrays instead of Strings Other Features and Tools. Small footprint smaller than 1. Having played around with the GKE and MiniKube one stop clusters, I wanted to build a multinode K8. Each connection instance maps to a single database. This method is helpful when mangaging multiple db connections. If arguments are passed, they are proxied to either. The primary purpose of this code is to teach beginner programmer to familiarize the concept of database programming. This is particularly for beginner but may also.

Derby only supports global temporary tables. The default H2 jar file contains debug information, jar files for other databases do not. Postgre. SQL supports functional indexes. Derby only supports updatable result sets if the query is not sorted. Derby doesnt support standard compliant information schema tables. When using MVCC multi version concurrency.

H2 in Use For a list of applications that work with or use H2, see Links. Connection Modes The following connection modes are supported Embedded mode local connections using JDBC Server mode remote connections using JDBC or ODBC over TCPIP Mixed mode local and remote connections at the same time Embedded Mode In embedded mode, an application opens a database from within the same JVM using JDBC. This is the fastest and easiest connection mode. The disadvantage is that a database may only be open in one virtual machine and class loader at any time. As in all modes, both persistent and in memory databases are supported. There is no limit on the number of database open concurrently, or on the number of open connections. Server Mode When using the server mode sometimes called remote mode or clientserver mode, an application opens a database remotely using the JDBC or ODBC API. A server needs to be started within the same or another virtual machine, or on another computer. Many applications can connect to the same database at the same time, by connecting to this server. Internally, the server process opens the databases in embedded mode. The server mode is slower than the embedded mode, because all data is transferred over TCPIP. As in all modes, both persistent and in memory databases are supported. There is no limit on the number of database open concurrently per server, or on the number of open connections. Mixed Mode The mixed mode is a combination of the embedded and the server mode.
