表已创建。

2 is

//把list中的元素转换成自定义的类型
ARRAY array = new ARRAY(descriptor, connMyDB, newURLs);
/*重要！这里输出的全是“???”试验NLS
备注：如果在入库的过程中发现字符串的值没有入进去，
请检查有没有加载该类库orai18n.jar(11g之前:nls_charset12.jar)*/
proc.setArray(1, array); //给过程传参数
proc.execute();
String[] tem = (String[]) array.getArray(); //输出一下
for (String str : tem) {
System.out.println(str);
}
} catch (Exception ex) {
ex.printStackTrace();
} finally {
try {
if(connMyDB != null && !connMyDB.isClosed())
connMyDB.close();
} catch (SQLException ex) {
ex.printStackTrace();
}
}
}
}
运行以后在t表插入两行
SQL> select * from t;
B
-----------------------------------------------
abc
1234
