SELECT INTO 和 INSERT INTO SELECT 两种表复制语句

Insert是T-sql中常用语句，Insert INTO table(field1,field2,...) values(value1,value2,...)这种形式的在应用程序开发中必不可少。但我们在开发、测试过程中，经常会遇到需要表复制的情况，如将 一个table1的数据的部分字段复制到table2中，或者将整个table1复制到table2中，这时候我们就要使用 SELECT INTO 和 INSERT INTO SELECT 表复制语句了。 1. INSERT INTO SELECT语句 语句形式为： Insert into Table2(field1,field2,...) select value1,value2,... from Table1 要求目标表Table2必须存在，由于目标表Table2已经存在，所以我们除了插入源表Table1的字段外，还可以插入常量。示例如下： -- 1.创建测试表 create TABLE Table1 ( a varchar ( 10 ), b varchar ( 10 ), c varchar ( 10 ), CONSTRAINT [ PK_Table1 ] PRIMARY KEY CLUSTERED ( a ASC ) ) ON [ PRIMARY ] create TABLE Table2 ( a varchar ( 10 )

This is the code: <select id=

问题 Just getting my head around Linq and having lots of fun! Can any one aid me with a query for this: I have a list of data: Key Value Aaa 12 AaA 10 AAa 5 BBB 2 Bbb 1 1. I want to group by Key.ToUpper() 2. For every group I need the Max(Value) & Sum(Value) 3. For every group I want to select the entries There the Value != Max(value) the final result should be like this: Key Max Total AaA 12 27 AAa 12 27 Bbb 2 3 Thanks! Update, actually I also need the Key from the Maximum entry: Key Max Total

问题 I have a sample data, i want to get the Difference in month over month data 'Lag' column for only row B 回答1: If there always is just one row per month and id , then just use lag() . You can wrap this in a case expression so it only applies to id 'B' . select id, date, data, case when id = 'B' then data - lag(data) over(partition by id order by date) end lag_diff from mytable 来源： https://stackoverflow.com/questions/62160736/running-difference-month-over-month
