我有这样的数组.我想要的是获取特定值的索引值.即,我想知道值"UD"等的索引.
Array
(
[0] => LN
[1] => TYP
[2] => UD
[3] => LAG
[4] => LO
)
我怎样才能做到这一点？？
我有一个XML文件,它有四个<resutGroups>标记:
<resultGroups>
<subGroups>
<name> </name>
</subGroups>
<name> </name>
</resultGroups>
每个<resultGroup>都有几个<subGroups>,每个<subGroups>都有<name>标签.
我只想选择的名称标签<resultGroups>唯一
$(xml).find("resultGroups").each(function() {
alert( $(this).find("name").text() );
}
当我使用上面的代码返回里面所有的名字<resultgroups>和<subGroups>.
我怎么只能选择一个<name>它是在<resultGroups>标签？
我有一个带有html文本区域的表单.我想在php中获取此文本区域的内容,以便每行可以存储在一个数组中.我尝试使用'/ n'进行内爆.但它不起作用.我怎样才能做到这一点.
这是我的代码
$notes = explode('/n',$_POST['notes']);
我有一个oracle函数,如下所示.当我在sql-developer中运行它时会出错
ORA-06502:PL/SQL:数字或值错误:字符串缓冲区错误太小.
但是,DBMS_OUTPUT.PUT_LINE(FINAL_RESULT)函数中的行正在输出窗口中打印预期的输出.
任何人都可以帮我吗？
create or replace

我写了这样的查询.它正在工作并给我我想要的结果.
我有一个SELECT查询来获取CAR_AMOUNT和HOTEL_AMOUNT.
但是,我必须重复相同的SELECT查询来获得SUM两者.我无法使用别名.我怎么能避免这个？
SELECT B.EMPLOYEE_ID,
(select SUM(AMOUNT)
FROM travel_reimbursements_items
WHERE type = 'CAR'
AND travel_request_no = B.travel_request_no
AND STATUS='APPROVED') as CAR_AMOUNT,
(select SUM(AMOUNT)
FROM travel_reimbursements_items
WHERE type = 'HOTEL'
AND travel_request_no = B.travel_request_no
AND STATUS='APPROVED') as HOTEL_AMOUNT,
NVL((select SUM(AMOUNT)
FROM travel_reimbursements_items
WHERE type = 'CAR'
AND travel_request_no = B.travel_request_no
AND STATUS='APPROVED'),0)
+NVL((select SUM(AMOUNT)
FROM travel_reimbursements_items
WHERE type = 'HOTEL'
AND travel_request_no = B.travel_request_no
AND STATUS='APPROVED'),0) as TOTAL
FROM TRAVEL_REQUEST_ITEM A …我想在我的oracle db中禁用存档日志.但是当我关机并尝试安装数据库时,我收到以下错误.
