Using database metadata
To query a database for information about what it supports, the Microsoft JDBC Driver for SQL Server implements the SQLServerDatabaseMetaData class. This class contains many methods that return information in the form of a single value, or as a result set.
To create a SQLServerDatabaseMetaData object, you can use the getMetaData method of the SQLServerConnection class to get information about the database that it's connected to.
In the following example, an open connection to the AdventureWorks2022 sample database is passed in to the function. Then the getMetaData method of the SQLServerConnection class is used to return a SQLServerDatabaseMetadata object. Finally, various SQLServerDatabaseMetaData methods are used to display information about the driver, driver version, database name, and database version.
public static void getDatabaseMetaData(Connection con) {
try {
DatabaseMetaData dbmd = con.getMetaData();
System.out.println("dbmd:driver version = " + dbmd.getDriverVersion());
System.out.println("dbmd:driver name = " + dbmd.getDriverName());
System.out.println("db name = " + dbmd.getDatabaseProductName());
System.out.println("db ver = " + dbmd.getDatabaseProductVersion());
}
// Handle any errors that may have occurred.
catch (SQLException e) {
e.printStackTrace();
}
}
