sql的行转列(PIVOT)与列转行(UNPIVOT)
在做数据统计的时候，行转列，列转行是经常碰到的问题。case when方式太麻烦了，而且可扩展性不强，可以使用 PIVOT，UNPIVOT比较快速实现行转列，列转行，而且可扩展性强
一、行转列
1、测试数据准备
CREATE TABLE [StudentScores] ( [UserName] NVARCHAR(20), --学生姓名 [Subject] NVARCHAR(30), --科目 [Score] FLOAT, --成绩 ) INSERT INTO [StudentScores] SELECT '张三', '语文', 80 INSERT INTO [StudentScores] SELECT '张三', '数学', 90 INSERT INTO [StudentScores] SELECT '张三', '英语', 70 INSERT INTO [StudentScores] SELECT '张三', '生物', 85 INSERT INTO [StudentScores] SELECT '李四', '语文', 80 INSERT INTO [StudentScores] SELECT '李四', '数学', 92 INSERT INTO [StudentScores] SELECT '李四', '英语', 76 INSERT INTO [StudentScores] SELECT '李四', '生物', 88 INSERT INTO [StudentScores] SELECT '码农', '语文', 60 INSERT INTO [StudentScores] SELECT '码农', '数学', 82 INSERT INTO [StudentScores] SELECT '码农', '英语', 96 INSERT INTO [StudentScores] SELECT '码农', '生物', 78
2、行转列sql
SELECT * FROM [StudentScores] /*数据源*/
AS P
PIVOT
(
SUM(Score/*行转列后 列的值*/) FOR
p.Subject/*需要行转列的列*/ IN ([语文],[数学],[英语],[生物]/*列的值*/)
) AS T
执行结果：
二、列转行
1、测试数据准备
CREATE TABLE ProgrectDetail
(
ProgrectName NVARCHAR(20), --工程名称
OverseaSupply INT, --海外供应商供给数量
NativeSupply INT, --国内供应商供给数量
SouthSupply INT, --南方供应商供给数量
NorthSupply INT --北方供应商供给数量
)
INSERT INTO ProgrectDetail
SELECT 'A', 100, 200, 50, 50
UNION ALL
SELECT 'B', 200, 300, 150, 150
UNION ALL
SELECT 'C', 159, 400, 20, 320
UNION ALL
2、列转行的sql
SELECT P.ProgrectName,P.Supplier,P.SupplyNum
FROM
(
SELECT ProgrectName, OverseaSupply, NativeSupply,
SouthSupply, NorthSupply
FROM ProgrectDetail
)T
UNPIVOT
(
SupplyNum FOR Supplier IN
(OverseaSupply, NativeSupply, SouthSupply, NorthSupply )
) P
执行结果：
webapi 跨域问题
参考：http://www.cnblogs.com/chenxizhang/p/3821703.html
给自己做个笔记
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Credentials", "true");
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "origin,x-requested-with,content-type");
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "POST,GET,OPTIONS");
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
在web.config中添加这段代码
<system.webServer> <httpProtocol> <customHeaders> <add name="Access-Control-Allow-Origin" value="*" /> <add name="Access-Control-Allow-Headers" value="Content-Type" /> <add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE, OPTIONS" /> </customHeaders> </httpProtocol> <handlers> <remove name="ExtensionlessUrlHandler-Integrated-4.0" /> <remove name="OPTIONSVerbHandler" /> <remove name="TRACEVerbHandler" /> <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" /> </handlers> </system.webServer>
Dapper 链式查询 扩展
Dapper 链式查询扩展 DapperSqlMaker
Github地址：https://github.com/mumumutou/DapperSqlMaker 欢迎大佬加入
Demo:
- 查询 TestsDapperSqlMaker\DapperSqlMaker.Test\ SelectDapperSqlMakerTest.cs
- 添加 TestsDapperSqlMaker\DapperSqlMaker.Test\ InsertDapperSqlMakerTest.cs
- 更新 TestsDapperSqlMaker\DapperSqlMaker.Test\ UpdateDapperSqlMakerTest.cs
- 删除 TestsDapperSqlMaker\DapperSqlMaker.Test\ DeleteDapperSqlMakerTest.cs
- 上下文类 TestsDapperSqlMaker\DbDapperSqlMaker\ LockDapperUtilsqlite.cs
简单栗子：
1.查询-联表查询,分页
1 public void 三表联表分页测试()
2 {
3 var arruser = new int[2] { 1,2 }; //
4 string uall = "b.*", pn1 = "%蛋蛋%", pn2 = "%m%";
5 LockPers lpmodel = new LockPers() { IsDel = false};
6 Users umodel = new Users() { UserName = "jiaojiao" };
7 SynNote snmodel = new SynNote() { Name = "木头" };
8 Expression<Func<LockPers, Users, SynNote, bool>> where = PredicateBuilder.WhereStart<LockPers, Users, SynNote>();
9 where = where.And((l, u, s) => ( l.Name.Contains(pn1) || l.Name.Contains(pn2) ));
10 where = where.And((lpw, uw, sn) => lpw.IsDel == lpmodel.IsDel);
11 where = where.And((l, u, s) => u.UserName == umodel.UserName);
12 where = where.And((l, u, s) => s.Name == snmodel.Name );
13 where = where.And((l, u, s) => SM.In(u.Id, arruser));
14
15 DapperSqlMaker<LockPers, Users, SynNote> query = LockDapperUtilsqlite<LockPers, Users, SynNote>
16 .Selec()
17 .Column((lp, u, s) => //null) //查询所有字段
18 new { lp.Name, lpid = lp.Id, x = "LENGTH(a.Prompt) as len", b = SM.Sql(uall)
, scontent = s.Content, sname = s.Name })
19 .FromJoin(JoinType.Left, (lpp, uu, snn) => uu.Id == lpp.UserId
20 , JoinType.Inner, (lpp, uu, snn) => uu.Id == snn.UserId)
21 .Where(where)
22 .Order((lp, w, sn) => new { lp.EditCount, x = SM.OrderDesc(lp.Name), sn.Content });
23
24 var result = query.ExcuteSelect();
25 WriteJson(result); // 查询结果
26
27 Tuple<StringBuilder, DynamicParameters> resultsqlparams = query.RawSqlParams();
28 WriteSqlParams(resultsqlparams); // 打印sql和参数
29
30 int page = 2, rows = 3, records;
31 var result2 = query.LoadPagelt(page, rows, out records);
32 WriteJson(result2); // 查询结果
33 }
生成的sql ：
select a.Name as Name, a.Id as lpid
, LENGTH(a.Prompt) as len, b.*
, c.Content as scontent, c.Name as sname
from LockPers a
left join Users b on b.Id = a.UserId
inner join SynNote c on b.Id = c.UserId
where ( a.Name like @Name0 or a.Name like @Name1 )
and a.IsDel = @IsDel2 and b.UserName = @UserName3
and c.Name = @Name4 and b.Id in @Id
order by a.EditCount, a.Name desc , c.Content
2.更新-更新部分字段
1 [Test]
2 public void 更新部分字段测试lt()
3 {
4 var issucs = LockDapperUtilsqlite<LockPers>.Cud.Update(
5 s =>
6 {
7 s.Name = "测试bool修改1";
8 s.Content = "update方法内赋值修改字段";
9 s.IsDel = true;
10 },
11 w => w.Name == "测试bool修改1" && w.IsDel == true
12 );
13 Console.WriteLine(issucs);
14 }
3.七联表以上待扩展 copy六联表修改3个文件
- DapperSqlMaker
- Template_DapperSqlMaker 上下文类
- PredicateBuilder 条件拼接类
4.实体生成T4模板使用方法 https://www.cnblogs.com/cl-blogs/p/7205954.html
