# 1, 基本语法 #

## a, terminal 的使用：常用命令 ##

############ 1,切换NameSpace (3种方式)
    USER>do ^%CD
    Namespace: t1
    You're in namespace T1
    Default directory is e:\helthc\mgr\t1\
    
    T1>set $namespace="demo"
    
    DEMO>zn "%sys"
    %SYS>
    ############ 2,变量赋值
    %SYS>set a="hello"
    %SYS>write a
    hello
    
    %SYS>s num=1+1
    %SYS>w num
    2
    
    ############ 3,w的特殊用法：w # -->清屏, w!-->换行
    %SYS>w !
    
    %SYS>w "a"_"b"
    ab
    ############ 4, 数组
    %SYS>set arr(0)=1
    %SYS>set arr(1)=2
    %SYS>set arr(1,1)="inner1"
    %SYS>set arr(1,2)="inner2"
    
    %SYS>zw arr
    arr(0)=1
    arr(1)=2
    arr(1,1)="inner1"
    arr(1,2)="inner2"
     
    %SYS>w arr(0)
    1
    %SYS>w arr(1)
    2
    %SYS>w arr(1,1)
    inner1

## b,逻辑控制：选择/循环 ##

*  if语句， case语句

USER>if 0{w "true"} else{w "false"}
    false
    USER>if 1{w "true"} else{w "false"}
    true
    USER>if 2{w "true"} else{w "false"}
    true
    
    USER>w "a"="a"
    1
    USER>w "a"="a1"
    0
    USER>if ("a"="a"){w "true"} else{w "false"}
    true
    USER>if ("a"="a1"){w "true"} else{w "false"}
    false
    
    --------------------case-------
    USER>w $case(1,1:"yes",2:"no",:"other")
    yes
    USER>w $case(2,1:"yes",2:"no",:"other")
    no
    USER>w $case(3,1:"yes",2:"no",:"other")
    other

*  for循环

USER>for x=1:1:5{w "output==>"_x,!}
    output==>1
    output==>2
    output==>3
    output==>4
    output==>5

## c, 常用函数 ##

*  随机数

USER>set num=$R(10)
    USER>w num
    6
    USER>w $R(2)
    1
    USER>w $R(2)
    0

*  时间函数，字符串截取

%SYS>w $H　　//date, time　秒计
    65352,35669
    
    %SYS>w $p("a b c"," ",1)
    a
    %SYS>w $p("a b c"," ",2)
    b
    %SYS>w $p($H,",",1)
    65352
    
    %SYS>w $zd($p($H,",",1))
    12/05/2019
    %SYS>w $zdt($p($h,",",1),1)
    12/05/2019
    %SYS>w $zdt($p($h,",",1),3)
    2019-12-05
    
    
    #获取年月日，时分秒
    TEST>set ymd=$p($H,",",1)
    TEST>set hms= $p($H,",",2)
    TEST>w $p($H,",",1)
    65934
    TEST>w $p($H,",",2)
    33278
    
    #随机数
    TEST>w $R(10)
    8
    TEST>w $R(10)
    2
    
    #生成时间
    TEST>WRITE $ZDATETIME(ymd_","_(hms- $R(10) ) , 3,1,3)
    2021-07-09 09:19:09.000
    
    TEST>WRITE $ZDATETIME($p($NOW(),",",1)_","_($p($NOW(),",",2) + (0.001* $R(1000)) ), 3,1,3)
    2021-07-09 10:00:51.687

# 2, 类与对象 #

*  在studio中创建一个类:  
    Demo命名空间–>new cache class (默认继承%Persistent类): 写入属性 -->编译

Class com.eyeof.Test1 Extends %Persistent
    { 
    	Property age As %Integer;
    	Property name As %String;
    	
    	//普通方法
    	Method f1()
    	{ 
    		w "hello world, Method f1 "
    	}
    	ClassMethod f2()
    	{ 
    		w "hello world, ClassMethod f1 "
    	}
    
    	//方法传参
    	Method info(salary1 As %Integer, profile1 As %Integer, name, state As %String = "CA")
    	{ 
    		w name_"/"_state_"/"_"total salary="_(salary1+profile1)
    	}
    	
    	//方法返回值
    	ClassMethod returnObj(name As %String, age As %Integer) As Test1
    	{ 
    	 	 Set person = ##class(Test1).%New()
    	     set person.name= name
    	     set person.age=age 
    		 Quit person
    	}
    	//以下是编译后，生成的代码段
    	Storage Default
    	{ 
    	<Data name="Test1DefaultData">
    	<Value name="1">
    	<Value>%%CLASSNAME</Value>
    	</Value>
    	<Value name="2">
    	<Value>count1</Value>
    	</Value>
    	<Value name="3">
    	<Value>count2</Value>
    	</Value>
    	<Value name="4">
    	<Value>age</Value>
    	</Value>
    	<Value name="5">
    	<Value>name</Value>
    	</Value>
    	</Data>
    	<DataLocation>^com.eyeof.Test1D</DataLocation>
    	<DefaultData>Test1DefaultData</DefaultData>
    	<IdLocation>^com.eyeof.Test1D</IdLocation>
    	<IndexLocation>^com.eyeof.Test1I</IndexLocation>
    	<StreamLocation>^com.eyeof.Test1S</StreamLocation>
    	<Type>%Library.CacheStorage</Type>
    	}
    }

*  使用终端：创建对象，调用方法

#切换到：该代码所在的namespace中
    Username: eyeof
    Password: ******
    USER>zn "t1"
    
    T1>do ##class(com.eyeof.Test1).f2()
    hello world, ClassMethod f1
     
    T1>set t1=##class(com.eyeof.Test1).%New()
    T1>d t1.f1()
    hello world, Method f1
    
    ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝方法传参==========
    T1>d t2.info(2000,500,"lisi")
    lisi/CA/total salary=2500
    
    T1>set salary=3000
    T1>set profile=500
    T1>set name="lisi"
    T1>do t2.info(.salary,.profile,.name)
    lisi/CA/total salary=3500
    
    ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝方法返回值==========
    T1 2e1>set obj= ##class(com.eyeof.Test1).returnObj("a",23)
     
    T1 2e1>zw obj
    obj=<OBJECT REFERENCE>[5@com.eyeof.Test1]
    +----------------- general information ---------------
    |      oref value: 5
    |      class name: com.eyeof.Test1
    | reference count: 2
    +----------------- attribute values ------------------
    |       %Concurrency = 1  <Set>
    |                age = 23
    |               name = "a"
    +-----------------------------------------------------

# 3, 类和数据库表 #

*  在studio 中创建类: 定义属性，方法

Class T1.Patient Extends (%Persistent, %XML.Adaptor, %Populate)
    { 
    Property IDCard As %String;
    Property PatNo As %String;
    Property Name As %String;
    Property Gender As %String;
    Property DOB As %Date;
    Property Citizenship As %String;
    Property PhoneNumber As %String;
    
    ClassMethod FindPatient(id As %String) As T1.Patient
    {   Set patient= ##class(T1.Patien).%OpenId(id) 
       Quit patient
    }
    
    ClassMethod GetPatientsByName(name As %String) As %ListOfObjects
    { 
    	set queryStr = "SELECT * FROM T1.Patient WHERE Name like ?"
    	set nameParameter = "%"_name_"%"
    	SET tStatement = ##class(%SQL.Statement).%New()
    	SET qStatus = tStatement.%Prepare(queryStr)
    	IF qStatus'=1 { WRITE "%Prepare failed:" DO $System.Status.DisplayError(qStatus) QUIT ""}
    	
    	#Dim rset As %SQL.StatementResult = tStatement.%Execute(nameParameter)
    	if 0'=rset.SQLCODE{ quit ""}
    	Write "Counts: ", rset.%ROWCOUNT,! 
    	
    	#Dim rtnList as %Library.ListOfObjects = ##class(%Library.ListOfObjects).%New()
    	WHILE rset.%Next() { 
    		#dim patInst As T1.Patient = ##class(T1.Patient).%New()
    		set patInst.Name = rset.%Get("Name")
    		set patInst.Gender = rset.%Get("Gender")
    		set patInst.DOB = rset.%Get("DOB")
    		do rtnList.Insert(patInst)
    	}
    	quit rtnList
    }
    }

*  在terminal中创建对象，保存到数据库的表中

T1>set p = ##class(T1.Patient).%New()
    T1>set p.PatNo = "234567"
    T1>set p.Name = "Li Xunhuan"
    T1>set p.Gender = "Male"
    T1>set p.DOB = $zdh("1980-10-01",3)
    T1>w p.%Save()
    1

*  在Potal中: 使用sql查看表数据

*  在terminal 中：随机生成10条数据, 查询记录, 测试xml的用法（打印，保存）

T1>d ##class(T1.Patient).Populate(10)
     
    T1>Do ##class(T1.Patient).XMLDTD()
    <!ELEMENT Patient (IDCard?,PatNo?,Name?,Gender?,DOB?,Citizenship?,PhoneNumber?)>
    <!ELEMENT IDCard (#PCDATA) >
    <!ELEMENT PatNo (#PCDATA) >
    <!ELEMENT Name (#PCDATA) >
    <!ELEMENT Gender (#PCDATA) >
    <!ELEMENT DOB (#PCDATA) >
    <!ELEMENT Citizenship (#PCDATA) >
    <!ELEMENT PhoneNumber (#PCDATA) >
     
    T1>Do ##class(T1.Patient).XMLSchema()
