H2 is a JAVA database. We can interact with this database by using JDBC. In this chapter, we will see how to create a JDBC connection with H2 database and the CRUD operations with the H2 database.

Then I thought maybe it's the JDBC URL that's the issue, so I tried: project.db.url jdbc:h2:tcp:\\\\localhost\\\\D:\\projects\\myproject\\data\\project java jdbc connection-string h2

H2 JDBC Driver and URL connection information such as driver class, URL format, etc..

Connecting to an Embedded (Local) Database. The database URL for connecting to a local database is jdbc:h2:[file:][].The prefix file: is optional. If no or only a relative path is used, then the current working directory is used as a starting point.

Step 8: Below is the code for the application.properties file server.port 8082 # H2 Database spring.h2.console.enabledtrue spring.datasource.urljdbc:h2:mem:dcbapp ...

DbSchema Tool already includes an H2 driver, which is automatically downloaded when you connect to H2. What is the JDBC URL? Each JDBC driver is using a specific URL. The URL is a string (text) with a specific format, containing information about the host where the database is running, the port, username, database name, etc.

java org.h2.tools.RunScript -url jdbc:h2:~/test -user sa -script test.zip -options compression zip For more information about the options, see the SQL command RUNSCRIPT. The restore can be done remotely, however the file needs to be on the server side. The built in FTP server could be used to copy the file to the server.

In the spring.datasource.url property, mem is the name of an in-memory database and testdb is the name of schema that H2 provides, by default. We can also define our own schema and database. The default username is sa and the blank password denotes an empty password. If we want to change the username and password, we can override these values.

So I have created a few schema in H2. How can I connect to a specific schema in H2 For example when I need to connect to a specific schema in SQL Server I have below JDBC URL jdbc:sqlserver://HOSTN...

For 1 MiB block sizes, use x 20 (because 2^20 is 1 MiB). The following file name means the logical file is split into 1 MiB blocks: split:20:~/test.h2.db. An example database URL for this case is jdbc:h2:split:20:~/test. Java Objects Serialization

The JDBC connection URL that you specify in the login screen is based on the curam.db.name, curam.db.username, and curam.db.h2.directory values in Bootstrap.properties. These values define the database name, SCHEMA name, and the database location in the file system.

"A file path that is implicitly relative to the current working directory is not allowed in the database URL"

H2, by default, drops your in memory database if there are no active connections. To prevent this add DB_CLOSE_DELAY-1 to the url (use a semicolon as a separator) eg: jdbc:h2:mem:play;MODEMYSQL;DB_CLOSE_DELAY-1. Uppercase for DB Tables. H2 DB, by default, creates tables with upper case names. Sometimes you don't want this to happen.

JDBC Driver Installation. The recommended way to install a JDBC driver into WildFly 8 is to deploy it as a regular JAR deployment. The reason for this is that when you run WildFly in domain mode, deployments are automatically propagated to all servers to which the deployment applies; thus distribution of the driver JAR is one less thing for you to worry about!
