The Database tab in Tool Properties defines settings for all connections of the specific database type. All supported database types (Oracle, Informix, SQL Server, Db2, MySQL, etc.)  are listed, and for each database type, there are a number of properties that are applied to any database connection of that type. This means, for instance, that a database connection defined as being a PostgreSQL database type will use the PostgreSQL properties defined in Tool Properties.

The list of parameters, their default values and parameter descriptions are determined by the JDBC driver used for the connection. Not all drivers supports support additional driver properties. To change a value, just modify it in the list. The first column in the list indicates whether the property has been modified or not, and so, whether DbVisualizer will pass that parameter and value onto the driver at connect time.

Invoke Java methods in the JDBC driver

In addition to driver properties it properties, it is also possible to invoke low-level Java methods in the JDBC driver classes, java.sql.Connection and java.sql.Statement. These are edited in the driver properties list.

You may run single argument methods taking one of String.class, Integer.class, or Boolean.class Java types as argument. The method name should be specified as Parameter which must be fully qualified with the all-lowercase class name. The argument is specified in the Value field in the driver properties list.

...

java.sql.connection methods are invoked just after a physical connection with the database has been established. java.sql.statement methods are invoked just after a statement has been created and is ready for execution.
