• Linq To Sql Entity Updated from Trigger

  - by James Helms

  I have a Table called Address. I have a Trigger for insert on that table that does some spacial calculations on the address that determines what neighborhood boundaries it is in. address = new Address { Street = this.Street, City = this.City, State = this.State, ZipCode = this.ZipCode, latitude = this.Latitude, longitude = this.Longitude, YearBuilt = this.YearBuilt, LotSize = this.LotSize, FinishedSize = this.FinishedSize, Bedrooms = this.Bedrooms, Bathrooms = this.Bathrooms, UseCode = this.UseCode, HOA = this.HOA, UpdateDate = DateTime.Now }; db.AddToAddresses(address); db.SaveChanges(); In the database i can clearly see that the Trigger ran and updated the neighborhoodID in the address table for the row. I tried to just reload that record to get the assigned id like this: address = (from a in db.Addresses where a.AddressID == address.AddressID select a).First(); In the debugger i can clearly see that the address.AddressID is correct, entity doesn't update in memory. Is there any work around for this?

• Performance improvement to a big if clause in SQL Server function

  - by Miles D

  I am maintaining a function in SQL Server 2005, that based on an integer input parameter needs to call different functions e.g. IF @rule_id = 1 -- execute function 1 ELSE IF @rule_id = 2 -- execute function 2 ELSE IF @rule_id = 3 ... etc The problem is that there are a fair few rules (about 100), and although the above is fairly readable, its performance isn't great. At the moment it's implemented as a series of IF's that do a binary-chop, which is much faster, but becomes fairly unpleasant to read and maintain. Any alternative ideas for something that performs well and is fairly maintainable?

• Copy Data from One SQL Server Table to Other in Same Database Without Specifying Columns

  - by Scott

  In SQL Server there is the ability to INSERT all of the data from one table into another using the following statement: INSERT INTO TABLE1 SELECT * FROM TABLE2 When running this on a table with an identity column, even though we have run the command SET IDENTITY_INSERT TABLE1 ON, we get the error: An explicit value for the identity column in table can only be specified when a column list is used and IDENTITY_INSERT is ON This implies that we would have to list off all of the columns within the INSERT in order for this to work properly. In the situation that we are in, we do not have access to the column names, only the list of the tables we need to copy over. Is there any way to get around this limitation?

• Should I rebuild table indexes after a SQL Server 2000 to 2005 database migration

  - by Joe T

  I'm tasked with doing a SQL Server 2000 to 2005 migration. I will be doing a side-by-side migration. After restoring from a backup I plan to do the following: ALTER DATABASE <database_name> SET COMPATIBILITY_LEVEL = 90; DBCC CHECKDB(<database_name>) WITH NO_INFOMSGS DBCC UPDATEUSAGE(<database_name>) WITH NO_INFOMSGS exec sp_updatestats ‘resample’ Should I rebuild table indexes before using DBCC UPDATEUSAGE and sp_updatestats? Have I missed anything obvious that should be executed after a migration? All help would be warmly up-voted. Thanks

• Linq to Sql query reuse

  - by UserControl

  Let's say we have a view V1 and V2 that is declared like: create view V2 as select V1.*, V2.C1, V2.C2, V2.C3 from V1 join V2 on V1.Key = V2.Key where bla-bla So V2 narrows down the result set of V1 and adds some joins. And there is a retrieval routine in C# IEnumerable<V1> GetData(MyFilter filter, MySortOrder order) {} I want to reuse with V2. Is it possible without performing joins in L2S rather than in database? Should i manually create a base class in the database context or something?

• SQL 2008 table locked - can't work out why

  - by Mr. Flibble

  I have two databases on one SQL 2008 server. Database 1 seems to be causing a lock on a table on database 2. There no queries are running on database 1 that should affect database 2. Is this normal behaviour? When I view the running queries with this command SELECT sqltext.TEXT, req.session_id, req.status, req.command, req.cpu_time, req.total_elapsed_time/1000 [seconds] FROM sys.dm_exec_requests req CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS sqltext it tells me as much, and says that the command on database 2 is suspended. I'm at a bit of a loss. What sort of things should I look at to work out why the table in database 2 is locked?

• How to do insert one row from one table to another table(what has less columns)?

  - by chobo2

  Hi I am trying to find rows that are not in one table and insert them into another. The table I am trying to insert into has less columns then the other one. These columns are null but it would be cool if I could hardcode a value before I do the insert. But I am having so much trouble with just trying to get it to insert. I have something like this SELECT p.ProductId, p.ProductName INTO SomeTable FROM Product as p WHERE p.ProductName != 'iPad' I will get a error like this though Msg 4104, Level 16, State 1, Line 1 The multi-part identifier "p.ProductId" could not be bound. I am not sure what I am doing wrong. I copied and pasted the names in so I don't think it is a spelling mistake. I am using ms sql 2005 express.

• Easy plugin or procedure for sqlserver Management Studio to script row inserts.

  - by Patrick Karcher

  I've never been able to find a good script or plugin for sql server Management Studio (2005 and or 2008) for a very common scripting need: specifying a few/all rows in a table and scripting their insert. You can guess my story: I've got some configuration data in my dev db and I need to script it for deployment to UAT and then production. I've found a few cludgy systems in the past, that were more trouble than they were worth. I need something free and unobtrusive. Once I find it I'll share it with the other 20 developers in my shop who are annoyed by this. Aren't we all annoyed by this by the way? What is the best, easiest, free, way to specify a few/all rows in a table and get a script their insert?

• SQL Server Express: Failed to add primary key after creating a database table

  - by Syd

  Scenario: I have created a database table. And when I tried to add a primary key (using the SQL Server Management Studiio) to the table, it failed with an error message "Saving changes is not permitted. The changes you have made requrie the following tables to be dropped and re-created. You have either made changes to a table that can't be recreated or enabled the option Prevent savign changes that require the table to be re-created." The environment is Windows 7. I have earlier installed it on a Windows XP SP2 and it worked. And yes, my table is empty (freshly created). My current workaround is to run the "Drop and Create" script. The other alternative is to create the primary key before I save the table. Is this a bug or a limitation with the Express version?

• Getting age in years in a SQL query

  - by Earlz

  Hello I've been tasked with doing a few queries on a large SQL Server 2000 database. The query I'm having trouble with is "find the number of people between ages 20 and 40" How would I do this? My previous query to get a count of everyone looks like this: select count(rid) from people where ... (with the ... being irrelevant conditions). I've googled some but the only thing I've found for calculating age is so large that I don't see how to embed it into a query, or it is a stored procedure which I do not have the permissions to create. Can someone help me with this?

• SQL compare entire rows

  - by zmaster

  In SQL server 2008 I have some huge tables (200-300+ cols). Every day we run a batch job generating a new table with timestamp appended to the name of the table. The the tables have no PK. I would like a generic way to compare 2 rows from two tables. Showing which cols having different values is sufficient, but showing the values would be perfect. Thanks a lot Thanks for the answers. I ended up writing my own C# tool to do the job - as Im not allowed to install 3rd party software in my company.

• Dynamically changing databases in SQL Server 2000

  - by spuppett

  At work we have a number of databases that we need to do the same operations on. I would like to write 1 SP that would loop over operations and set the database at the beginning of the loop (example to follow). I've tried sp_executesql('USE ' + @db_id) but that only sets the DB for the scope of that stored procedure. I don't really want to loop with hard coded database names because we need to do similar things in many different places and it's tough to remember where things need to change if we add another DB. Any thoughts Example: DECLARE zdb_loop CURSOR FAST_FORWARD FOR SELECT distinct db_id from DBS order by db_id OPEN zdb_loop FETCH NEXT FROM zdb_loop INTO @db_id WHILE @@FETCH_STATUS = 0 BEGIN USE @db_id --Do stuff against 3 or 4 different DBs FETCH NEXT FROM zdb_loop INTO @db_id END CLOSE zdb_loop DEALLOCATE zdb_loop

• What scenarios/settings will result in a query on SQL Server (2008) return stale data

  - by s1mm0t

  Most applications rarely need to display 100% accurate data. For example if this stack overflow question displays that there have been 0 views, when there have really been 10, it doesn't really matter. This is one way that the (perceived) performance of applications can be improved, by caching results and therefore sometimes not showing 100% accurate results. There are some cases where the data does need to be 100% accurate though. So if I run the query select * from Foo I want to be sure that the results are not stale. Now depending on how my database is set up, other activity on the database, use of transactions and isolation levels etc this query may or may not be a true reflection of the world. What scenario's and settings can people think of that will result in this query returning stale results or given that another connection is part way through a transaction that has updated this table, how can I guarantee that when the above query returns, the results will be accurate.

• sql - duplicates

  - by Sebastjan

  Hey guys I'm putting data from website (json) to sql base. In db i have these rows. ID | PostId | Name | Message Id is auto-increment primary key. PostId also has a unique values. Name and Message are nothing special. When I run my script / click on the button in form / ... , the program saves all the values into database (lets say there are 25). Next time I'm going to press the button there will be added 25 more records (all duplicates), and so on... Is there a way that the program can check through 'PostIds' if the value already exists before adding it to the db? Thanks

• Finding records within a 5 min time interval in SQL

  - by Mellonjollie

  I have a table with over 100,000 rows that contain the following columns: ID, Time, and Boolean. The time column tracks time down to the second. I need a query that will find all instances of Boolean = 1 for every 5 minute interval of time from the start of the table to the end, then group the count by time interval. The table represents 4 hours of data, so I should get 48 rows of results. I'm using MS SQL Server. I've tried a few approaches, but the time interval logic is giving me a hard time.

• SQL Server: Find Values that don't exist in a table

  - by MacAnthony

  I have a list or set of values that I would like to know which ones do not currently exist in a table. I know I can find out which ones do exist with: SELECT * FROM Table WHERE column1 IN (x,x,x,x,x) The set is the values I am checking against. Is there a way to find out which values in that set do not exist in column1? Basically, I'm looking for the inverse of the sql statement above. This is for a report, so all I need is the values that don't exist to be returned back. I have and could do this with a left join and putting the values in another table, but the values I check are always different and was hoping to find a solution that didn't involve clearing a table and inserting data first. Trying to find a better solution for me if one exists.
