大家用过Oracle JDBC驱动调用updateObject吗？？

[白乔]

我使用的驱动是classes12那个
不管createStatement使用什么参数，后面的updateObject就是报错：
对只读结果集的无效操作: updateObject

同样的代码使用mysql就没有问题
请问大家如何解决？你们用过Oracle JDBC驱动调用updateObject吗？？

[水园第四届唯一指定版主]

stmt = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,
ResultSet.CONCUR_UPDATABLE);
不行吗

[白乔]

public void testUpdateObject() throws Exception
{
Statement st =
connection.createStatement(
ResultSet.TYPE_SCROLL_SENSITIVE,
ResultSet.CONCUR_UPDATABLE);
ResultSet rs = st.executeQuery("select * from jdbc");
if (rs.next())
{
rs.updateObject("AINT", "1234");
rs.updateObject("ASTRING", Calendar.getInstance().toString());
rs.updateObject("ADATETIME", "1977-2-1");
try
{
int iPos = rs.findColumn("SOME");
rs.updateObject("SOME", "1977-2-1");
}
catch (Exception e)
{
}
rs.updateRow();
}

rs.close();
st.close();
}

我将代码改了改：
public void testUpdateObject() throws Exception
{
int aa[] =
{
ResultSet.TYPE_FORWARD_ONLY,
ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.TYPE_SCROLL_SENSITIVE };
int bb[] = { ResultSet.CONCUR_READ_ONLY, ResultSet.CONCUR_UPDATABLE };

for (int i = 0; i < aa.length; i++)
{
for (int j = 0; j < bb.length; j++)
{
System.out.println("[" + aa[i] + "," + bb[j] + "]");
try
{
Statement st = connection.createStatement(i, j);
ResultSet rs = st.executeQuery("select * from jdbc");
if (rs.next())
{
rs.updateObject("AINT", "1234");
rs.updateObject(
"ASTRING",
Calendar.getInstance().toString());
rs.updateObject("ADATETIME", "1977-2-1");

rs.updateRow();
rs.close();
st.close();
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
}

结果输出如下：
