我使用h2（h2-1.4.186.jar）数据库作为Java应用程序。我创建了2个数据库，一个是我用于许多任务的支持数据库。 在其中一个任务中，我需要一个表（从表f中选择f.field，h.field，从另一个数据库加入表h ecc ...）。所以我使用了'创建链接表＆＃39;。如果我从浏览器控制台执行查询它可以工作，但如果我在java方法中执行它不起作用。这是方法：
private void createTable()
{
String linkedTable="create force linked table if not exists "+TABLE_NAME+"('org.h2.Driver','jdbc:h2:../GLOBALDB/general','user','pass','("+getQuery()+")')";
try{
Connection conn=GenericDatabaseConnections.getConnectionDBThreads();
Statement sta=conn.createStatement();
try{
sta.execute(linkedTable);
sta.execute("SELECT * FROM "+TABLE_NAME);
}catch(Exception e){
e.printStackTrace();
}
sta.close();
conn.close();
}catch(Exception e){
e.printStackTrace();
}
}
我得到以下例外情况：

最后如果我在浏览器控制台打开的时候在java中这样做，它就可以了。 我该怎么办呢？ 附：抱歉我的英文不好
