Kylin jdbc驱动r支持元数据列表方法:
通过sql模式过滤器(比如 %)列出catalog、schema、table和column。
Driver driver = (Driver) Class.forName("org.apache.kylin.jdbc.Driver").newInstance();
Properties info = new Properties();
info.put("user", "ADMIN");
info.put("password", "KYLIN");
Connection conn = driver.connect("jdbc:kylin://localhost:7070/kylin_project_name", info);
Statement state = conn.createStatement();
ResultSet resultSet = state.executeQuery("select * from test_table");
ResultSet tables = conn.getMetaData().getTables(null, null, "dummy", null);
while (tables.next()) {
for (int i = 0; i < 10; i++) {
assertEquals("dummy", tables.getString(i + 1));
}
}
