问题 I have an SSIS package in Visual Studio 2014, and I want to raise an error in a Script Component if any records traverse a particular path out of a 3rd party transformation. I WANT to do this in C# 2012, but the FireError method gives an error: The best overloaded method match for 'Microsoft.SqlServer.Dts.Pipeline.Wrapper.IDTSComponentMetaData100.FireError(int, string, string, string, int, out bool)' has some invalid arguments When I try to do this: bool fireAgain = false;

问题 I have a table say Cases , which is using reference from Workers for three columns. Also there is one table Company to which workers belongs. Below is the schema: Cases [ CaseID, CaseNumber, Worker1, Worker2, Worker3 ] Workers [ WorkerID, ComapnyID] Company [CompanyID, CompanyName] Now I need case count for each company. So is it possible to make one join with workers and map all Worker1 , Worker2 and Worker3 columns? Is there any better option and performance impact? Note: Two workers from

问题 I have a column inside my SQL Server 2012 table which contains following Json data. [{"bvin":"145a7170ec1247cfa077257e236fad69","id":"b06f6aa5ecd84be3aab27559daffc3a4"}] Now I want to use this column data in my query like select * from tb1 left join tb2 on tb1.(this bvin inside my column) = tb2.bvin. Is there a way to query JSON data in SQL Server 2012? 回答1: Honestly, this is a terrible architecture for storing the data, and can result in some serious performance issues. If you truly don't

问题 I have a bit column on a table in a SQL Server 2012 database. I am trying to retrieve all the rows where this bit column is either NULL or NOT TRUE. This query does not bring back what it should: (returns 0 rows) Select * from table where bit_column_value <> 1 This query brings back the correct rows: Select * from table where bit_column_value IS NULL Now, I'd be happy to use the second query, but my issue is that, in a similar query for another table, the reverse of the above is true, where

问题 I am trying to concatenate multiple columns in a query in SQL Server 11.00.3393. I tried the new function CONCAT() but it's not working when I use more than two columns. So I wonder if that's the best way to solve the problem: SELECT CONCAT(CONCAT(CONCAT(COLUMN1,COLUMN2),COLUMN3),COLUMN4) FROM myTable I can't use COLUMN1 + COLUMN2 because of NULL values. EDIT If I try SELECT CONCAT('1','2','3') AS RESULT I get an error The CONCAT function requires 2 argument(s) 回答1: Through discourse it's

问题 Is there any difference between left join and inner join regarding performance? I use SQL Server 2012. 回答1: There is at least one case where LEFT [OUTER] JOIN is a better option than [INNER] JOIN . I talk about getting the same results using OUTER instead of INNER . Example (I am using AdventureWorks 2008 database): -- Some metadata infos SELECT fk.is_not_trusted, fk.name FROM sys.foreign_keys fk WHERE fk.parent_object_id=object_id('Sales.SalesOrderDetail'); GO CREATE VIEW View1 AS SELECT h

问题 I was in the middle of implementing a database audit trail whereby CRUD operations performed through my controllers in my Web API project would serialize the old and new poco's and store their values for later retrieval (historical, rollback, etc...). When I got it all working, I did not like how it made my controllers look during a POST because I ended up having to call SaveChanges() twice, once to get the ID for the inserted entity and then again to commit the audit record which needed to

问题 I get this error when deploying a package to SQL 2012 SSISDB catalog: A .NET Framework error occurred during execution user-defined routine or aggregate "deploy-project-internal": System.Data.SqlClient.SqlException: The locale identifier (LCID) 9242 is not supported by SQL Server ...... 回答1: I had a very similar issue (different LCID) and took me weeks to resolve it but I hope is the same issue you where having and it helps for any other users. So somehow something got bad installed on the

问题 My friend sent me the commands that he wrote in server 2008 and they worked with no problems, mine however from a copy and past did not work with 2012. Is there any reason why? Here is the code: Use Kudler_Database SELECT AccountNumber, [Description], ShortDescription,Balance FROM Chart_of_Accounts ORDER BY left (AccountNumber, 2) COMPUTE SUM(Balance) BY left (AccountNumber, 2) COMPUTE SUM(Balance); Here is the error : Msg 156, Level 15, State 1, Line 6 Incorrect syntax near the keyword

问题 Currently I'm using Visual Studio 2012 RC and SQL Server 2012 RTM. I'd like to know how to re-deploy/re-create a test database for each test run. Keep in mind I've a SQL Server database project for the database using Visual Studio 2012's template. Actually I'm not very sure about an idea I got in my mind, but .testsettings file has Setup and cleanup scripts . Is this the way to go? For example, a PowerShell script reading the database project generated script and executing it against the
