如何使用Java JDBC获取MySql的数据库"Schema"名称列表？

Answer 1

getSchemas()DatabaseMetaData 的方法很明显,但是你必须使用MySQLgetCatalogs()

http://download.oracle.com/javase/7/docs/api/java/sql/DatabaseMetaData.html#getSchemas() http://download.oracle.com/javase/7/docs/api/java/sql /DatabaseMetaData.html#getCatalogs()

例:

Class.forName("com.mysql.jdbc.Driver");

// change user and password as you need it
Connection con = DriverManager.getConnection (connectionURL, "user", "password");

ResultSet rs = con.getMetaData().getCatalogs();

while (rs.next()) {
    System.out.println("TABLE_CAT = " + rs.getString("TABLE_CAT") );
}
