• BULK INSERT from one table to another all on the server

  - by steve_d

  I have to copy a bunch of data from one database table into another. I can't use SELECT ... INTO because one of the columns is an identity column. Also, I have some changes to make to the schema. I was able to use the export data wizard to create an SSIS package, which I then edited in Visual Studio 2005 to make the changes desired and whatnot. It's certainly faster than an INSERT INTO, but it seems silly to me to download the data to a different computer just to upload it back again. (Assuming that I am correct that that's what the SSIS package is doing). Is there an equivalent to BULK INSERT that runs directly on the server, allows keeping identity values, and pulls data from a table? (as far as I can tell, BULK INSERT can only pull data from a file) Edit: I do know about IDENTITY_INSERT, but because there is a fair amount of data involved, INSERT INTO ... SELECT is kinda of slow. SSIS/BULK INSERT dumps the data into the table without regards to indexes and logging and whatnot, so it's faster. (Of course creating the clustered index on the table once it's populated is not fast, but it's still faster than the INSERT INTO...SELECT that I tried in my first attempt) Edit 2: The schema changes include (but are not limited to) the following: 1. Splitting one table into two new tables. In the future each will have its own IDENTITY column, but for the migration I think it will be simplest to use the identity from the original table as the identity for the both new tables. Once the migration is over one of the tables will have a one-to-many relationship to the other. 2. Moving columns from one table to another. 3. Deleting some cross reference tables that only cross referenced 1-to-1. Instead the reference will be a foreign key in one of the two tables. 4. Some new columns will be created with default values. 5. Some tables aren’t changing at all, but I have to copy them over due to the "put it all in a new DB" request.

• Adding Days To Date in SQL

  - by Coding Noob

  I am trying to get data from my Database of those who have upcoming birth days in next few days(declared earlier) it's working fine for days but this query will not work if i add 24 days to current date cause than it will need change in month. i wonder how can i do it declare @date int=10, @month int=0 select * from STUDENT_INFO where DATEPART(DD,STDNT_DOB) between DATEPART(DD,GETDATE()) and DATEPART(DD,DATEADD(DD,@date,GETDATE())) and DATEPART(MM,STDNT_DOB) = DATEPART(MM,DATEADD(MM,@month,GETDATE())) This query works fine but it only checks date between 8 & 18 but if i use it like this declare @date int=30, @month int=0 select * from STUDENT_INFO where DATEPART(DD,STDNT_DOB) between DATEPART(DD,GETDATE()) and DATEPART(DD,DATEADD(DD,@date,GETDATE())) and DATEPART(MM,STDNT_DOB) = DATEPART(MM,DATEADD(MM,@month,GETDATE())) it will return nothing since it require addition in month as well If I Use it like this declare @date int=40, @month int=0 select * from STUDENT_INFO where DATEPART(DD,STDNT_DOB) between DATEPART(DD,GETDATE()) and DATEADD(DD,@date,GETDATE()) and DATEPART(MM,STDNT_DOB) = DATEPART(MM,DATEADD(MM,@month,GETDATE())) than it will return results till the last of this month but will not show till 18/12 which was required

• Sql: simultaneous aggregate from two tables

  - by Ash

  I have two tables: a Files table, which includes the file type, and a File Properties table, which references the file table via a foreign key. Sample Files table: | id | name | type | --------------------- | 1 | file1 | zip | | 2 | file2 | zip | | 3 | file3 | zip | | 4 | file4 | jpg | And the Properties table: | file_id | property | ----------------------- | 1 | x | | 2 | x | I want to make a query, which shows the count of each file type, and how many files of that type have a property. So in the example, the result would be | type | filecount | prop count | ---------------------------------- | zip | 3 | 2 | | jpg | 1 | 0 | I could accomplish this by select f.type, (select count(id) from files where type = f.type), count(fp.id) from files as f, file_properties as fp where f.id = fp.file_id group by f.type; But this seems very suboptimal and is very slow. Any better way to do this?

• Inserting Strings Without Trailing Spaces SQL

  - by Soo

  I have a database with a field named Field1 that has 100 nchars per entry. Each time I add a value, it is stored as: "value (100-ValueLength Spaces) " So Basically each stored value has a string of spaces after it. This is getting to be an issue when I try doing: if (value == "Example") because of all of the empty spaces after the string. How can I get it so the stored values don't have all of these trailing spaces?

• More efficient left join of big table

  - by Zeus

  Hello, I have the following (simplified) query select P.peopleID, P.peopleName, ED.DataNumber from peopleTable P left outer join ( select PE.peopleID, PE.DataNumber from formElements FE inner join peopleExtra PE on PE.ElementID = FE.FormElementID where FE.FormComponentID = 42 ) ED on ED.peopleID = P.peopleID Without the sub-query this procedure takes ~7 seconds, but with it, it takes about 3minutes. Given that table peopleExtra is rather large, is there a more efficient way to do that join (short of restructuring the DB) ?

• How Serializable works with insert in SQL Server 2005

  - by Spence

  G'day I think I have a misunderstanding of serializable. I have two tables (data, transaction) which I insert information into in a serializable transaction (either they are both in, or both out, but not in limbo). SET TRANSACTION ISOLATION LEVEL SERIALIZABLE BEGIN TRANSACTION INSERT INTO dbo.data (ID, data) VALUES (@Id, data) INSERT INTO dbo.transactions(ID, info) VALUES (@ID, @info) COMMIT TRANSACTION I have a reconcile query which checks the data table for entries where there is no transaction at read committed isolation level. INSERT INTO reconciles (ReconcileID, DataID) SELECT Reconcile = @ReconcileID, ID FROM Data WHERE NOT EXISTS (SELECT 1 FROM TRANSACTIONS WHERE data.id = transactions.id) Note that the ID is actually a composite (2 column) key, so I can't use a NOT IN operator My understanding was that the second query would exclude any values written into data without their transaction as this insert was happening at serializable and the read was occurring at read committed. I have evidence that reconcile is picking up entries

• Whats wrong with my SQL query?

  - by William

  I'm trying to set up a query that shows the first post of each thread and is ordered by the date of the last post in each thread. I got the first part down with this query: SELECT * FROM ( SELECT Min( ID ) AS MinID FROM test_posts GROUP BY Thread )tmin JOIN test_posts ON test_posts.ID = tmin.MinID Now I need to figure out how to call the last post of each thread into a table, than use that table to order the first tables results. So far I got this, but it doesn't work. SELECT * FROM ( SELECT Min( ID ) AS MinID FROM test_posts GROUP BY Thread )tmin JOIN test_posts ON test_posts.ID = tmin.MinID ORDER BY (SELECT MAX( ID ) AS MaxID, Thread, MAX( Date ) FROM test_posts GROUP BY Thread )tmax tmax.Date

• Need help tuning a SQL statement

  - by jeffself

  I've got a table that has two fields (custno and custno2) that need to be searched from a query. I didn't design this table, so don't scream at me. :-) I need to find all records where either the custno or custno2 matches the value returned from a query on the same table based on a titleno. In other words, the user types in 1234 for the titleno. My query searches the table to find the custno associated with the titleno. It also looks for the custno2 for that titleno. Then it needs to do a search on the same table for all other records that have either the custno or custno2 returned in the previous search in the custno or custno2 fields for those other records. Here is what I've come up with: SELECT BILLYR, BILLNO, TITLENO, VINID, TAXPAID, DUEDATE, DATEPIF, PROPDESC FROM TRCDBA.BILLSPAID WHERE CUSTNO IN (select custno from trcdba.billspaid where titleno = '1234' union select custno2 from trcdba.billspaid where titleno = '1234' and custno2 != '') OR CUSTNO2 IN (select custno from trcdba.billspaid where titleno = '1234' union select custno2 from trcdba.billspaid where titleno = '1234' and custno2 != '') The query takes about 5-10 seconds to return data. Can it be rewritten to work faster?

• SQL: how to get the left 3 numbers from an int

  - by dmr

  I want to retrieve the left 3 numbers from an integer to be stored in a table. For example, if the int is 1234567, I want to retrieve 123. I want the second number (123) to also be an int; I don't want to convert anything to a string. (And yes, really I should be working with strings. But I don't have control over that aspect of the issue.) Thank you!

• Select return dynamic columns

  - by Ascalonian

  I have two tables: Standards and Service Offerings. A Standard can have multiple Service Offerings. Each Standard can have a different number of Service Offerings associated to it. What I need to be able to do is write a view that will return some common data and then list the service offerings on one line. For example: Standard Id | Description | SO #1 | SO #2 | SO #3 | ... | SO #21 | SO Count 1 | One | A | B | C | ... | G | 21 2 | Two | A | | | ... | | 1 3 | Three | B | D | E | ... | | 3 I have no idea how to write this. The number of SO columns is set to a specific number (21 in this case), so we cannot exceed past that. Any ideas on how to approach this? A place I started is below. It just returned multiple rows for each Service Offering, when they need to be on one row. SELECT * FROM SERVICE_OFFERINGS WHERE STANDARD_KEY IN (SELECT STANDARD_KEY FROM STANDARDS)

• Can't get DataGridView to refresh over Linq to SQL (WinForm)

  - by GringoFrenzy

  Very strange situation here: I'm using L2S to populate a DataGridView. Code follows: private void RefreshUserGrid() { var UserQuery = from userRecord in this.DataContext.tblUsers orderby userRecord.DisplayName select userRecord; UsersGridView.DataSource = UserQuery; //I have also tried //this.UserBindingSource.DataSource = UserQuery; //UsersGridView.Datasource = UserBindingSource; UsersGridView.Columns[0].Visible = false; } Whenever I use L2S to Add/Delete records from the database, the GridView refreshes perfectly well. However, if someone is editing the grid and makes a mistake, I want them to be able to hit a refresh button and have their mistakes erased by reloading from the datasource. For the life of me, I can't get it to work. The code I am currently using on my refresh button is this: private void button1_Click(object sender, EventArgs e) { this.DataContext.Refresh(RefreshMode.OverwriteCurrentValues); RefreshUserGrid(); } But the damn GridView remains unaffected. All that happens is the selected row becomes unselected. I have tried .Refresh(), .Invalidate(), I've tried changing the DataSource to NULL and back again (all suggestions from similar posts here)....none of it works. The only time the Grid refreshes is if I restart the app. I must be missing something fundamental, but I'm totally stumped and so are my colleagues. Any ideas? Thanks!

• Help needed with Linq To Sql Query

  - by fearofawhackplanet

  I have the concept of valid/ordered transitions. So for example, it's not possible to move to status In progress from status Complete. Current and Next in table StatusTransition are FK (StatusType.Id). The Linq generator has created the following relations: Child Property Name: StatusTransitions1 Parent Property Name: StatusType1 Participating Properties: StatusType.Id -> StatusTransition.Next Child Property Name: StatusTransitions Parent Property Name: StatusType Participating Properties: StatusType.Id -> StatusTransition.Current I'm normally ok with Linq but I'm having difficulty getting the list of valid Next StatusTypes from the Current status. public List<StatusType> GetValidStatusTransitions(int statusId) { // trying to write something like the following // (obviously not correct) return _statusRepository .Where(s => s.Id == statusId) .Next.StatusTypes; }

• Big table or multiple separate tables? (database design question)

  - by Khou

  This is a database design question. I want to build an invoice web application, an invoice can have many items, and each user can have an inventory list of product items that they can store and choose to add to an invoice item. My questions are: 1. Should I store all product inventory for all users using my application under one single table? Or have a separate product inventory table created for each user? 2. Is this even possible? 1 table is easier, but what if this single table grows too big, will I have a problem? (primary key INT).

• SQL statement HAVING MAX(some+thing)=some+thing

  - by Andreas

  I'm having trouble with Microsoft Access 2003, it's complaining about this statement: select cardnr from change where year(date)<2009 group by cardnr having max(time+date) = (time+date) and cardto='VIP' What I want to do is, for every distinct cardnr in the table change, to find the row with the latest (time+date) that is before year 2009, and then just select the rows with cardto='VIP'. This validator says it's OK, Access says it's not OK. This is the message I get: "you tried to execute a query that does not include the specified expression 'max(time+date)=time+date and cardto='VIP' and cardnr=' as part of an aggregate function." Could someone please explain what I'm doing wrong and the right way to do it? Thanks

• Improve SQL Server 2005 Query Performance

  - by user366810

  I have a course search engine and when I try to do a search, it takes too long to show search results. You can try to do a search here http://76.12.87.164/cpd/testperformance.cfm At that page you can also see the database tables and indexes, if any. I'm not using Stored Procedures - the queries are inline using Coldfusion. I think I need to create some indexes but I'm not sure what kind (clustered, non-clustered) and on what columns. Thanks
