查询同一表内多字段同时重复记录的SQL语句
来自：7th string
比如现在有一人员表 （表名：peosons）
若想将姓名、身份证号、住址这三个字段完全相同的记录查询出来 select p1.* from persons p1,persons p2 where p1.id<>p2.id and p1.cardid = p2.cardid and p1.pname = p2.pname and p1.address = p2.address
可以实现上述效果．
几个删除重复记录的SQL语句
1.用rowid方法
2.用group by方法
3.用distinct方法
1。用rowid方法
据据Oracle带的rowid属性，进行判断，是否存在重复,语句如下：
查数据:
select * from table1 a where rowid !=(select max(rowid)
from table1 b where a.name1=b.name1 and a.name2=b.name2......)
删数据：
delete from table1 a where rowid !=(select max(rowid)
from table1 b where a.name1=b.name1 and a.name2=b.name2......)
2.group by方法
查数据:
select count(num), max(name) from student --列出重复的记录数，并列出他的name属性
group by num
having count(num) >1 --按num分组后找出表中num列重复，即出现次数大于一次
删数据：
delete from student
group by num
having count(num) >1
这样的话就把所有重复的都删除了。
3.用distinct方法 -对于小的表比较有用
create table table_new as select distinct * from table1 minux
truncate table table1;
insert into table1 select * from table_new;
查询及删除重复记录的方法大全
1、查找表中多余的重复记录，重复记录是根据单个字段（peopleId）来判断
select * from people
where peopleId in (select peopleId from people group by peopleId having count(peopleId) > 1)
2、删除表中多余的重复记录，重复记录是根据单个字段（peopleId）来判断，只留有rowid最小的记录
delete from people
where peopleId in (select peopleId from people group by peopleId having count(peopleId) > 1)
and rowid not in (select min(rowid) from people group by peopleId having count(peopleId )>1)
3、查找表中多余的重复记录（多个字段）
select * from vitae a
where (a.peopleId,a.seq) in (select peopleId,seq from vitae group by peopleId,seq having count(*) > 1)
4、删除表中多余的重复记录（多个字段），只留有rowid最小的记录
delete from vitae a
where (a.peopleId,a.seq) in (select peopleId,seq from vitae group by peopleId,seq having count(*) > 1)
and rowid not in (select min(rowid) from vitae group by peopleId,seq having count(*)>1)
5、查找表中多余的重复记录（多个字段），不包含rowid最小的记录
select * from vitae a
where (a.peopleId,a.seq) in (select peopleId,seq from vitae group by peopleId,seq having count(*) > 1)
and rowid not in (select min(rowid) from vitae group by peopleId,seq having count(*)>1)
(二)
比方说
在A表中存在一个字段“name”，
而且不同记录之间的“name”值有可能会相同，
现在就是需要查询出在该表中的各记录之间，“name”值存在重复的项；
Select Name,Count(*) From A Group By Name Having Count(*) > 1
如果还查性别也相同大则如下:
Select Name,sex,Count(*) From A Group By Name,sex Having Count(*) > 1
(三)
方法一
declare @max integer,@id integer
declare cur_rows cursor local for select 主字段,count(*) from 表名 group by 主字段 having count(*) >； 1
open cur_rows
fetch cur_rows into @id,@max
while @@fetch_status=0
begin
select @max = @max -1
set rowcount @max
delete from 表名 where 主字段 = @id
fetch cur_rows into @id,@max
end
close cur_rows
set rowcount 0
方法二
＂重复记录＂有两个意义上的重复记录，一是完全重复的记录，也即所有字段均重复的记录，二是部分关键字段重复的记录，比如Name字段重复，而其他字段不一定重复或都重复可以忽略。
1、对于第一种重复，比较容易解决，使用
select distinct * from tableName
就可以得到无重复记录的结果集。
如果该表需要删除重复的记录（重复记录保留1条），可以按以下方法删除
select distinct * into #Tmp from tableName
drop table tableName
select * into tableName from #Tmp
drop table #Tmp
发生这种重复的原因是表设计不周产生的，增加唯一索引列即可解决。
2、这类重复问题通常要求保留重复记录中的第一条记录，操作方法如下
假设有重复的字段为Name,Address，要求得到这两个字段唯一的结果集
select identity(int,1,1) as autoID, * into #Tmp from tableName
select min(autoID) as autoID into #Tmp2 from #Tmp group by Name,autoID
select * from #Tmp where autoID in(select autoID from #tmp2)
最后一个select即得到了Name，Address不重复的结果集（但多了一个autoID字段，实际写时可以写在select子句中省去此列）
(四)
查询重复
select * from tablename where id in (
select id from tablename
group by id
having count(id) > 1
)

fread執行結果：
2014-07-31 11:14:36 start.
2014-07-31 11:18:51 end.
用時：4分15秒
將fwrite($fpWrite, fread($fpRead, 512));改成fwrite($fpWrite, fread($fpRead, 1024));
執行結果：
2014-07-31 11:29:11 start.
2014-07-31 11:32:26 end.
用時：3分15秒
從性能上分析，應該是fread會更好，不佔用太多內存。

| jquery mobile 动态添加元素demo | jquery mobile | http://my.oschina.net/jgy/blog/101058 | |
添加一个<input type='button' value='OK' id="btn_OK"/>然后调用jquery mobile 方法:$('#btn_OK').button();
jquery 表单元素每一个元素都有自己刷新的方法，每当改变它们的属性以后，都要执行这些方法，以下是实例：
复选按钮
$("input[type='checkbox']").attr("checked",true).checkboxradio("refresh");
单选按钮组:
$("input[type='radio']").attr("checked",true).checkboxradio("refresh");
选择列表::
var myselect = $("select#foo");
myselect[0].selectedIndex = 3;
myselect.selectmenu("refresh");
滑动条
$("input[type=range]").val(60).slider("refresh");
开关 (they use slider):
var myswitch = $("select#bar");
myswitch[0].selectedIndex = 1;
myswitch .slider("refresh");
1.Textarea field
1
$('body').prepend('<textarea id="myTextArea"></textarea>');

10
</fieldset>
11
</div>
12
13
$("input[value=grid]").attr('checked',true).checkboxradio('refresh');</span>
8. Checkboxes
1
<div data-role="fieldcontain">
2
<fieldset data-role="controlgroup">
3
<legend>Agree to the terms:</legend>

<label for="checkbox-1">I agree</label>
6
</fieldset>
7
</div>
8
9
$('#checkbox-1').attr('checked',true).checkboxradio('refresh');
还有很多还需要慢慢发现！我做的是一个移动点餐系统：目前产品界面显示如下图：不知道有没有谁自己封装的listview，或者号的插件推荐我使用的！或有更好的建议……欢迎发表。。。。。

<?php
header("Content-Type: application/force-download");
header("Content-Disposition: attachment; filename=ins.jpg");
readfile("imgs/test_Zoom.jpg");
?>
第一行代码是强制下载；
第二行代码是给下载的内容指定一个名字；
第三行代码是把下载的内容读进文件中。
如何在PHP下载文件名中解决乱码
通过把Content-Type设置为application/octet-stream，可以把动态生成的内容当作文件来下载，相信这个大家都会。那么用Content-Disposition设置下载的文件名，这个也有不少人知道吧。基本上，下载程序都是这么写的：
<?php
$filename = "document.txt";
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=' . $filename);
print "Hello!";
?>
这样用浏览器打开之后，就可以下载document.txt。
但是，如果$filename是UTF-8编码的，有些浏览器就无法正常处理了。比如把上面那个程序稍稍改一下：
<?php
$filename = "中文 文件名.txt";
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=' . $filename);
print "Hello!";
?>
把程序保存成UTF-8编码再访问，IE6下载的文件名就会乱码。 FF3下下载的文件名就只有“中文”两个字。Opera 9下一切正常。
输出的header实际上是这样子：
Content-Disposition: attachment; filename=中文 文件名.txt其实按照RFC2231的定义，多语言编码的Content-Disposition应该这么定义：
Content-Disposition: attachment; filename*="utf8''%E4%B8%AD%E6%96%87%20%E6%96%87%E4%BB%B6%E5%90%8D.txt"
即：
filename后面的等号之前要加 *
filename的值用单引号分成三段，分别是字符集(utf8)、语言(空)和urlencode过的文件名。
最好加上双引号，否则文件名中空格后面的部分在Firefox中显示不出来
注意urlencode的结果与php的urlencode函数结果不太相同，php的urlencode会把空格替换成+，而这里需要替换成%20
经过试验，发现几种主流浏览器的支持情况如下：
IE6 attachment; filename="<URL编码之后的UTF-8文件名>"
FF3 attachment; filename="UTF-8文件名"
attachment; filename*="utf8''<URL编码之后的UTF-8文件名>"
O9 attachment; filename="UTF-8文件名"
Safari3(Win) 貌似不支持？上述方法都不行
这样看来，程序必须得这样写才能支持所有主流浏览器：
<?php
$ua = $_SERVER["HTTP_USER_AGENT"];
$filename = "中文 文件名.txt";
$encoded_filename = urlencode($filename);
$encoded_filename = str_replace("+", "%20", $encoded_filename);
header('Content-Type: application/octet-stream');
if (preg_match("/MSIE/", $ua)) {
header('Content-Disposition: attachment; filename="' . $encoded_filename . '"');
} else if (preg_match("/Firefox/", $ua)) {
header('Content-Disposition: attachment; filename*="utf8\'\'' . $filename . '"');
} else {
header('Content-Disposition: attachment; filename="' . $filename . '"');
}
print 'ABC';
?>
转自：http://www.alixixi.com/program/a/2011030368164.shtml
网上类似的文章有很多，这篇对我有用，收藏了
找这种方法，主要是自己要做PHPExcel操作保存文件，在文件名搜狗下正常显示空格，IE空格变成了 '_' ，firefox直接截取了空格前的作为文件名，
参照上面文章，稍微修改了下，以防以后用得到：
<?php
.............//phpexcel操作略
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$filename =“中 文.xlsx”;
$ua = $_SERVER["HTTP_USER_AGENT"];
$encoded_filename = urlencode($filename);
$encoded_filename = str_replace("+", "%20", $encoded_filename);
header('Content-Type: application/vnd.ms-excel');
//header("Content-Disposition: attachment;filename=".$filename);
if (preg_match("/MSIE/", $ua)) {
header('Content-Disposition: attachment; filename="' . $encoded_filename . '"');
} else if (preg_match("/Firefox/", $ua)) {
header('Content-Disposition: attachment; filename*="utf8\'\'' . $filename . '"');
} else {
header('Content-Disposition: attachment; filename="' . $filename . '"');
}
$objWriter->save('php://output');
?>

6 获取当前语言环境(hostEnvironment也包含了当前应用类型，如indesign，photoshop。
hostEnv.appName
hostEnv.isAppOffline 是否在线
appLocale 语言
appVersion 版本)
[Bindable]
private var currentUILocale:String;
private function onCreationComplete() : void

8 判断网络是否可用(as)
/**
* Determines if the Creative Suite product has a network
* connection
*/
public function computeOnline():void
{
var res:Boolean = false;
var result:SyncRequestResult = CSXSInterface.getInstance().getNetworkPreferences();
var networkPreferences:NetworkPreferences;
if ((result.status == SyncRequestResult.COMPLETE) && result.data)
{
networkPreferences = result.data as NetworkPreferences;
if (networkPreferences.overallOnlinePreference)
{
//online preference are enabled, so go online
res = true;
}
}
this.getModel().online = res;
if (this.getModel().online == false)
{
this.getModel().notifier = "Polyglot is unavailable due to lack of network access";
}
}
9 XMPMETA DATA 操作(as)
创建XMPMeta 必须指定命名空间来访问
var meta:XMPMeta = new XMPMeta();
//var xmp:Namespace = new Namespace("http://ns.adobe.com/xap/1.0/");
var nmg:Namespace = new Namespace("my", "http://com.nmg.xmp/");
meta.nmg::CreatorTool = "Indesign";//设置属性CreatorTool为Indesign
//下面是2个命名空间
meta.xmpNS::Rating = 4;
meta.my::simpleProp = "value";
读取属性
trace(meta.xmpNS::Rating); // shows "4"
trace(meta.my::simpleProp); // shows "value"
更新属性
meta.xmpNS::Rating = 5;
meta.my::simpleProp = "new value";
删除属性
meta.my::simpleProp = null;
—or—
delete meta.my::simpleProp;
判断属性是否存在
trace( meta.xmpNS::Rating.exists() ); // true
trace( meta.my::simpleProp.exists() ); // false
trace( meta.my::simpleProp.toString() ); // null
数据类型转换
The XMPMeta object provides convenience methods for retrieving String property values as literal types:
toBoolean()
toInteger()
toFloat()
toDate()
添加结构化XMP属性（对象属性）
var effect:Namespace = new Namespace("effect","http://com.nmg.xmp.effect/");
var struct:XMPStruct = new XMPStruct();
struct.effect::effectId = "1";
struct.effect::effectType = "slideshow";
// add the structured property to the XMP object
meta.nmg::struct = struct;
// Retrieve a struct field
Log.add (meta.nmg::struct.effect::effectType);
删除结构化XMP属性
meta.nmg::struct = null
—or—
delete meta.nmg::struct
添加数组属性
以下三种添加类型
meta.my::bagArray = XMPArray.newBag();// 保存字符串
meta.my::seqArray = XMPArray.newSeq();
meta.my::altArray = XMPArray.newAlt();//保存struct对象结构
添加数组元素方式
To add items, use the square brackets, "[...]" operator, or the append() and insert() methods of the XMPArray object.
获取最后一个元素
The special index value "last()" accesses the last item: meta.my::bagArray ["last()"].
trace(meta.my::seqArray[5]); // prints "five"
trace(meta.my::seqArray["last()"]); // prints "five"
length();获取数组长度
通过对象方式设置array
meta.nmg::effectArray = XMPArray.newAlt();
var effectArray:XMPArray = new XMPArray();
effectArray.setType(2);//0:newBag,1:newSeq,2:newAlt
effectArray.append(struct);
effectArray.append(struct2);
meta.nmg::effectArray = effectArray;
注意：不能通过effectArray[1]的方式访问子节点。XMPArray.toString()和struct.toString()（输出<struct>）都无法获取到对应的字符串内容。
输出XMPMETADATA
var metaStr:String = meta.serialize();
var metaBuffer:ByteArray = meta.serializeToBuffer();
var metaXML:XML = meta.serializeToXML();
遍历XMP METADATA
Iterate through all property values of a structured property:
for each (var prop: XMPNode in meta.my::struct)
{
trace(prop);
}
Iterate through all property names of a structured property:
for (var propName: String in meta.my::struct)
{
trace(prop);
}
Iterate through the names of all top-level properties:
for (var propName: String in meta)
{
trace(prop);
}
Iterate through all items of an array property:
for each (var prop: XMPNode in meta.my::array)
{
trace(prop);
}
10 不通过XMP存储数据(as)
CSXS提供了一种存储和读取的机制，可以再indesign重启后依然能拿到数据。只能存储string类型。
通过ID识别。ID通过AMF转换再转换为BASE64格式的字符串。
可设置是否与其它extention扩展共享数据。
这种机制不支持在不同的电脑中共享数据。只针对当前电脑的indesign。

13 写入文件的XMP metadata（js）
注意：若当前文件正在打开，则无法写入。
// load the XMPScript library
if (ExternalObject.AdobeXMPScript == undefined)
ExternalObject.AdobeXMPScript = new ExternalObject('lib:AdobeXMPScript');
var filePath = "/C/Users/davidhuang/Documents/未命名-2.indd";
var file = new File(filePath);
var xmpFile = new XMPFile(file.fsName, XMPConst.UNKNOWN,XMPConst.OPEN_FOR_UPDATE);//XMPConst.OPEN_FOR_UPDATE
var xmp = xmpFile.getXMP();
// delete existing authors and add a new one
// existing metadata stays untouched
xmp.deleteProperty(XMPConst.NS_DC, "creator");
xmp.appendArrayItem(XMPConst.NS_DC, "going", "DAVIDTEST", 0,XMPConst.ARRAY_IS_ORDERED);
xmp.appendArrayItem(XMPConst.NS_DC, "creator", "INDESIGN", 0,XMPConst.ARRAY_IS_ORDERED);
// write updated metadata into the file
if (xmpFile.canPutXMP(xmp)) {
xmpFile.putXMP(xmp);
}
xmpFile.closeFile(XMPConst.CLOSE_UPDATE_SAFELY);
14 提取文件的XMP数据并保存到xml文件（js）
//load XMP Library
var XMPload = Boolean(false);
if (ExternalObject.AdobeXMPScript == undefined){
try {
ExternalObject.AdobeXMPScript = new ExternalObject('lib:AdobeXMPScript');
XMPload = true;
}catch(ex)
{
alert("Unable to load the AdobeXMPScript library!");
}
}
if(XMPload){
var myFile = File(app.selection[0].graphics[0].itemLink.filePath);//获取当前选择的第一个图片文件路径
xmpFile = new XMPFile(myFile.fsName, XMPConst.UNKNOWN, XMPConst.OPEN_FOR_READ);
xmp = xmpFile.getXMP();
var myXmp = xmp.serialize();
$.writeln(myXmp);//输出XMPDATA
xmpFile.closeFile(XMPConst.CLOSE_UPDATE_SAFELY);
}
writeXMP(myXmp, File('/e/myxmp.xml'));//保存到指定文件。需先创建文件
function writeXMP(xmpData, xmpFile){
xmpFile.open ( 'w', 'Text');
xmpFile.encoding = 'UTF-8';
xmpFile.write (xmpData);
xmpFile.close ();
}
15 给当前文档的添加新的xmp 属性（js as）
var myDocXMP = app.activeDocument.metadataPreferences;
var destNamespace = "http://ns.adobe.com/xap/1.0/";//这是xmp已存在的命名空间。若输入一个不存在的命名空间则不会添加成功
var destNodeName = "MyTesting";
var nodeValue = "IndiSnip test value";
myDocXMP.setProperty(destNamespace, destNodeName, nodeValue);
as代码实现
private function fileInfo():void{
var fileInfo:FileInfoLibrary = new FileInfoLibrary();
var doc:Document = InDesign.app.activeDocument;
var metaData:MetadataPreference = doc.metadataPreferences;
var effect:Namespace = new Namespace("effect","http://com.nmg.xmp.effect/");
var destNamespace:String = "http://ns.adobe.com/xap/1.0/";
metaData.setProperty(destNamespace,"abc","ddd");
}

var destNamespace = "http://ns.adobe.com/xap/1.0/";
var destContName = "IndiSnip";
myDocXMP.createContainerItem(destNamespace, destContName, undefined, ContainerType.BAG);
输出：
<xmp:IndiSnip>
<rdf:Bag>
<rdf:li/>
</rdf:Bag>
</xmp:IndiSnip>
as版本
private function fileInfo():void{
var doc:Document = InDesign.app.activeDocument;
var metaData:MetadataPreference = doc.metadataPreferences;
var destNamespace:String = "http://com.nmg.xmp.effect/";
var orgNS:String = "http://ns.adobe.com/xap/1.0/";
var destContName:String = "nmgEffect";
metaData.createContainerItem(destNamespace,destContName,0,ContainerType.ALT);//无法新增 。无此命名空间
metaData.setProperty(orgNS,"effectId","1");//新增属性成功
metaData.setProperty(destNamespace,"effectType","slideshow");//失败。无此命名空间
Log.add(metaData.getProperty(orgNS,"effectId"));//读取属性
doc.save();
//输出
// <xmp:nmgEffect>
// <rdf:Alt>
// <rdf:li/>
// </rdf:Alt>
// </xmp:nmgEffect>
}
注意：不能通过新增的命名空间添加属性。无法创建新的命名空间。
17 打开idnn文件并注册XMP 命名空间添加属性。（js）
注意：若该文件已经打开则运行失败。
