sql-server-2008-r2

问题 I want to know, is there any reflection support in SQL Server 2008, like as c# support reflection. Basically I am curious about how SQL Server implements all our (where, orderby, exists) clauses. How it would implement all these in behind the scenes. 回答1: It's not that long ago when if you compared SQLServer to most object-oriented languages, that you would have been struck by the fact that SQLServer reveals a lot more about its inner workings than they do. Its inherent to the concept of SQL

问题 I am working on a portion of a manufacturing DB. The business takes in custom orders and builds items to spec. They only build several (let's say 3-10) types of objects, but each type of object is different in the specifications that get recorded. I want to have a master manufacturing table (mfgorders) that lists some common fields and then have it refer to a specifications table that is specific to the entity ordered. I'm not entirely confident this is the right approach. In fact, I'm not

问题 I have an Excel-sheet as below, I already dump the data into database (as the sample data below) from this excel in normalized form. Now I want to get the similar view of excel from database's data. I tried this, but given in wrong format. Good if somebody given the same result view as excel with column name and inner join. I do not want to hardcore as the year expand. declare @tblyear table(id int, year int) insert into @tblyear values (1,2012), (2,2013),(3,2014) ,(4,2015),(5,2016) declare

问题 I have an entity class with the following annotation on its primary key: @GeneratedValue(strategy = GenerationType.AUTO) . However, when I try to persist an instance of this class, I get com.microsoft.sqlserver.jdbc.SQLServerException: Invalid object name 'OPENJPA_SEQUENCE_TABLE'. at com.microsoft.sqlserver.jdbc.SQLServerException.makeFromDatabaseError(SQLServerException.java:197) The table it's looking for definitely does not exist in the database. The user it's connecting to the database as

问题 If I have data in the format; Account | Period | Values Revenue | 2013-01-01 | 5432 Revenue | 2013-02-01 | 6471 Revenue | 2013-03-01 | 7231 Costs | 2013-01-01 | 4321 Costs | 2013-02-01 | 5672 Costs | 2013-03-01 | 4562 And I want to get results out like; Account | Period | Values Margin | 2013-01-01 | 1111 Margin | 2013-02-01 | 799 Margin | 2013-03-01 | 2669 M% | 2013-01-01 | .20 M% | 2013-02-01 | .13 M% | 2013-03-01 | .37 Where Margin = Revenue - Costs and M% is (Revenue - Costs)/Revenue for

问题 Due to performance perspective I just need to remove loop and using some joins or other solution to update the data in #Result table and get the same result which return by loop. Scalar function: CREATE FUNCTION [MultiplyerScl] (@a INT, @b INT) RETURNS INT AS BEGIN DECLARE @i AS INT = 2 DECLARE @Value AS INT IF (@b % @a = 0) BEGIN SET @Value = @b END ELSE BEGIN WHILE (1=1) BEGIN IF((@b * @i) % @a = 0) BEGIN SET @Value = @b * @i BREAK; END ELSE BEGIN SET @i = @i + 1 END END END RETURN @Value

问题 I am working on SQL Server 2008 R2. I am trying to get the sum. This is my query select SUM( case when sec.SecurityTypeID = 2 then SUM(quantity)*(sec.AnnualIncomeRate/100) when sec.SecurityTypeID = 5 then 0 when sec.SecurityTypeID = 11 then SUM(quantity)*sec.AnnualIncomeRate else SUM(quantity)*sec.AnnualIncomeRate end ) AS ProjectedIncome from Transactions as t When I execute it give me following error. Msg 130, Level 15, State 1, Line 3 Cannot perform an aggregate function on an expression

问题 LEFT OUTER JOIN [INVENTTRANS] ON #TEMP.VOUCHERPHYSICAL=[INVENTTRANS].VOUCHERPHYSICAL WHERE [INVENTTRANS].ITEMID = #Temp.INVENTDIMID This provides me nearly the result I am looking for. About 1/4th of the desired results are eliminated because INVENTDIMID has a suffix appended to it in certain cases. What is the proper syntax to succeed in a like clause similar to this intent. WHERE '[INVENTTRANS].ITEMID%' like #Temp.INVENTDIMID Alternatively, if there is no short hand way to do this, what is

问题 I`m was wonder if it is possible to hash sensitive data in mssql via function and to leave first character “as-is” for all the fields. Example: "Jon Kirk” name should be extracted as J** K*** 回答1: I had posted a recursive solution at first. This is faster: declare @name varchar(20) = 'Jon Kirk' declare @loop int = len(@name) while @loop > 1 select @name = stuff(@name, @loop, 1, case when substring(@name, @loop-1,2) like '% ' then ' ' when substring(@name, @loop-1,2) like ' %' then substring(

问题 This question already has an answer here : How to delete all tables with prefix “bkp” from a given database? (1 answer) Closed 6 years ago . I am trying to drop tables from each server/DB. I ran the query to get the list of the tables in each database from different server. SELECT * FROM sys.objects WHERE type = 'u' AND name LIKE '%JSK%' I want to drop those tables. I need query how to do it? 回答1: Assuming no foreign key relationships make order of dropping important: DECLARE @sql NVARCHAR
