Question

我在这一行收到了这个错误：

Object[] results = (Object[])stmt.getArray(1).getArray();

不确定这意味着什么...

我也可以显示sql ...有人可以解释这个错误意味着什么......如果需要我也有那个stac跟踪

不熟悉OracleCallableStatement，但不应该

Object[] results = (Object[])(stmt.getARRAY(1).getArray());

oracle.jdbc.OracleCallableStatement#getARRAY(int)是OracleCallableStatement - 具体，getArray()似乎是从java.sql.CallableStatement#getArray(int)继承的。

我已经说过我对此并不熟悉，但getARRAY似乎更适合您注册为out参数的OracleTypes.ARRAY类型。

java.sql.SQLException：内部错误：无效的类型oid？
