在日常工作中,可能需要使用重复的命令,修改的只是某个不同字段的值,可以使用连接字符串进行拼接 #本篇文档: 一.使用连接符拼接SQL 二.Spool输出查询结果 三.Spool输出xml/ html格式内容 1.1连接符 举例A:对某个用户下的表进行drop >select 'Drop table '||owner||'.'||table_name||';' from dba_tables where owner='HR' and table_name not in('EMPLOYEES','
数据范例如下: 要得到的结果目标,获取type相同的所有names拼接在一起的字符串: SqlServer并没有一个直接拼接字符串的函数,下面所提到的方法,只是日常的开发中自己个人用到的一些思路,仅供参考! )) 创建表变量,字段为你需要返回的各列的值 insert @tempTable select [type],MAX([name]) name from test group by [type] 插入初始的聚合数据 updateTag: update @tempTable set [name
--查询所有数据select A.*,B.* from(select z.id,z.requestId,z.FBillNo,dt5.FCauseAndProcess,dt5.FEquipmentNo,dt2.FDetail,row_number() over (PARTITION BY z.id ORDER BY z.id) RNfrom formtable z left join formtable2 dt2 on dt2.mainid=z.idleft join formtable5 dt5
SELECT B.id , LEFT(tempname, LEN(tempname) - 1) AS name FROM ( SELECT id , ( SELECT name + ',' FROM tablename WHERE id = A.id FOR XML PATH('') ) AS tempname FROM tablename A GROUP BY id ) B
if($irb_order!=''){ $condition .= " AND d.irb_order like '%".$irb_order."%'"; } if($company_name!=''){ $condition .= " AND cp.company_name like '%".$company_name."%'"; }
1. 基本的查询语句后面加上 WHERE 1=1,便于增加查询条件. ASkStr := 'select * from Twork where 1=1 '; if length(cxTEworkid.Text) <> 0 then begin ASkStr := ASkStr + ' and GWORKID like ' + quotedstr('%' + cxTEworkid.Text + '%') end; 2. 多表查询可以用一个字符串代替一个表.逻辑上更清晰. WorkTable =
1 exec sp_executesql N'SELECT 2 [Extent2].[Id] AS [Id], 3 [Extent2].[Name] AS [Name], 4 [Extent2].[Description] AS [Description], 5 [Extent2].[RoleTypeNum] AS [RoleTypeNum], 6 [Extent2].[IsDeleted] AS [IsDeleted], 7 [Extent2].[AddDate] AS [AddDate],
题目: 求组织机构ID在('5dc8de20-9f2f-465e-afcc-f69abecaee50','63549b63-1e0d-4269-98f4-013869d7f211','f7316bf3-38e9-47d4-ab95-8c702b468a2e','61e381d1-c8fc-4276-97e0-3f1b6a0356f5') 中的所有机构. 错误写法: select * from dd_Report where 1=1 and OrganizationID in('5dc8de20-
