Question

我有一个使用复杂SQL编写的Crystal Report，我尝试使用Crystal Report Java API调用它。此报告具有与之关联的Command对象。

我加载报告并设置连接参数。
然后我尝试将Connection信息设置为当前的JDBC Profile。含义测试环境凭据。

我得到一个例外。我尝试使用版本11.版本12。他们似乎都没有工作。

当我调用下面的代码时，我得到了异常。这段代码可以很好地处理没有＆＃34; Command＆＃34; sql语句。

try{
    clientDoc.getDatabaseController().setTableLocation(
    origTable, newTable);
}catch(Exception ex){
    ex.printStackTrace();
}

请参阅下面的整个代码。如果有人知道如何解决这个问题，请回复。

Answer 1

在你的这一行后添加

connectionInfo.setPassword(DB_PASSWORD); 
newTable.setConnectionInfo(connectionInfo);
//This will add connection parameters to the new table

而不是

clientDoc.getDatabaseController().setTableLocation(origTable, newTable);

用

替换它

clientDoc.getDatabaseController ().setTableLocation (newTable,  tables.getTable(i));
