This command has two uses. Sign up or log in Sign up using Google. Configuring this Logger will affect all of the log messages generated by the driver. The application developer will normally not need to call any function of the Driver directly.
HSQLDB – Connect
Examples reported by users include web application servers, where the closing of the last connection coincides with the web application being shut down.
One is for test suites, where connections to the database are made from one JVM context, immediately followed by another context. The getPropertyInfo method is intended to allow a generic GUI tool to discover what properties it should prompt a human for in order to get enough information to connect to a database. Normally at least a “user” and “password” property should be included.
It does not use the default value that it would use for the property if the value is null. This method is not intended to encourage the development of non-JDBC compliant drivers, but is a recognition of the fact that some vendors are interested in using the JDBC API and framework for lightweight databases that do not support full database functionality, or for special databases such as document information retrieval where a SQL implementation may not be feasible.

When the last connection to a database is closed, the database is automatically shut down. This means the connection that opens the database.
Driver Provides the java. Note that depending on the values the human has supplied so far, fornake values may become necessary, so it may be necessary to iterate though several calls to getPropertyInfo.
Hence, under JDBC 4.

The DriverManager will try to load as many drivers as it can find and then for any given connection request, it will ask each driver in turn to try to connect to the target URL. Starting with JDBC 4.

Return the parent Logger of all fornqme Loggers used by this driver. Also affects the semantics of DatabaseMetaData calls that supply null-valued schemaNamePattern parameter values. You need to add hsqldb jar to classpath, in this case you can copy it to folder where your Java class is located, then you need to compile it with -cp flag for example javac -cp.
