    MonetDB supplies a % pure Java JDBC driver (type 4) which allows to connect createStatement(); // execute SQL query which returns a ResultSet object. getConnection("jdbc:monetdb://localhost/mytest2", "monetdb", "monetdb");^M Statement st = Statement();^M ResultSet rs;^M ^M rs. A MonetDBLite JDBC connection is very similar to a regular connection with columnName, int row) retrieve a single value from the result set.
    To connect to an in-memory database the directory must be :memory: or not present.

    When starting a JDBC Embedded connection, it checks if there is a database instance running in the provided directory, otherwise an exception is thrown. The methods Savepoint setSavepointSavepoint setSavepoint String namevoid releaseSavepoint Savepoint savepoint and void rollback Savepoint savepoint handle savepoints within the transaction.

    For update queries e. The following example shows how it can be done. Due to limitations of representation of booleans in Java, to append to a boolean column, a byte array should be used instead, as shown in the example.

    For all other types, there are no changes. Unlike a traditional socket connection, in an embedded connection, both the client and the server share the same process, which means there is no necessity to serialize and deserialize data, or using an IPC method, making the connection faster.
