  • Possible to get PrimayKey IDs back after a SQL BulkCopy?

    - by chobo2
    Hi I am using C# and using SqlBulkCopy. I have a problem though. I need to do a mass insert into one table then another mass insert into another table. These 2 have a PK/FK relationship. Table A Field1 -PK auto incrementing (easy to do SqlBulkCopy as straight forward) Table B Field1 -PK/FK - This field makes the relationship and is also the PK of this table. It is not auto incrementing and needs to have the same id as to the row in Table A. So these tables have a one to one relationship but I am unsure how to get back all those PK Id that the mass insert made since I need them for Table B.

  • SQL exclude a column using SELECT * [except columnA] FROM tableA?

    - by uu?????s
    We all know that to select all columns from a table, we can use SELECT * FROM tableA Is there a way to exclude column(s) from a table without specifying all the columns? SELECT * [except columnA] FROM tableA The only way that I know is to manually specify all the columns and exclude the unwanted column. This is really time consuming so I'm looking for ways to save time and effort on this, as well as future maintenance should the table has more/less columns. thanks!

  • SQL Server Error: maximum number of prefixes. The maximum is 3.

    - by Ian Boyd
    Trying to run a cross-server update: UPDATE cmslive.CMSFintrac.dbo.lsipos SET PostHistorySequencenNmber = ( SELECT TransactionNumber FROM Transactions WHERE Transactions.TransactionDate = cmslive.CMSFintrac.dbo.lsipos.TransactionDate) Gives the error: Server: Msg 117, Level 15, State 2, Line 5 The number name 'cmslive.CMSFintrac.dbo.lsipos' contains more than the maximum number of prefixes. The maximum is 3. What gives? Note: Rearranging the query into a less readable join form: UPDATE cmslive.CMSFintrac.dbo.lsipos SET PostHistorySequenceNumber = B.TransactionNumber FROM cmslive.CMSFintrac.dbo.lsipos A INNER JOIN Transactions B ON A.TransactionDate = B.TransactionDate does not give an error.

  • SQL: without a cursor, how to select records making a unique integer id (identity like) for dups?

    - by Dr. Zim
    If you have the select statement below where the PK is the primary key: select distinct dbo.DateAsInt( dateEntered) * 100 as PK, recordDescription as Data from MyTable and the output is something like this (the first numbers are spaced for clarity): PK Data 2010 01 01 00 New Years Day 2010 01 01 00 Make Resolutions 2010 01 01 00 Return Gifts 2010 02 14 00 Valentines day 2010 02 14 00 Buy flowers and you want to output something like this: PK Data 2010 01 01 01 New Years Day 2010 01 01 02 Make Resolutions 2010 01 01 03 Return Gifts 2010 02 14 01 Valentines day 2010 02 14 02 Buy flowers Is it possible to make the "00" in the PK have an "identity" number effect within a single select? Otherwise, how could you increment the number by 1 for each found activity for that date? I am already thinking as I type to try something like Sum(case when ?? then 1 end) with a group by.

  • .NET app - Should we use SQL Server and duplicate some reference data from an external Oracle DB? Or use Oracle and have a DB link?

    - by Daventry
    We're looking to migrate some existing Excel/Access processes into a new system which will provide the users with a Silverlight frontend to run and view the reports instead of using MS Access. The initial idea was to have SQL Server 2008 as RDBMS. The problem is that we've got some static data such as country codes, counterparties, etc which live in an existing Oracle DB. Since we do not want to duplicate that data (if possible), we were thinking of having a DB link between SQL Server and Oracle, but our firm does not allow that. So the options are either duplicate the data or use Oracle as RDBMS - surprise, the firm does allow DB links between Oracle databases. The initial idea was also to use WCF RIA Services, Entity Framework, etc which we're not sure they play well with Oracle, that's why it was decided to go with SQL Server in the first place. Would you advise to go for Oracle so that we can just link the static data? Or use SQL Server 2008 and replicate it because it's "safer" to stay within the Microsoft land? To use or not to use Entity Framework and WCF RIA Services at all? Regards. UPDATE: Thanks everyone for your answers. Nothing is set in stone yet. We'll try to import the data instead of linking, as if the other DB goes down, our system can still carry on. We're likely to use SQL Server just because most developers are more experienced with it. Even if we used RIA Services, we can swap out the Data Access Layer and use other frameworks such those mentioned below.

  • Migrate Data and Schema from MySQL to SQL Server

    - by colithium
    Are there any free solutions for automatically migrating a database from MySQL to SQL Server Server that "just works"? I've been attempting this simple (at least I thought so) task all day now. I've tried: SQL Server Management Studio's Import Data feature Create an empty database Tasks - Import Data... .NET Framework Data Provider for Odbc Valid DSN (verified it connects) Copy data from one or more tables or views Check 1 VERY simple table Click Preview Get Error: The preview data could not be retrieved. ADDITIONAL INFORMATION: ERROR [42000] [MySQL][ODBC 5.1 Driver][mysqld-5.1.45-community]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '"table_name"' at line 1 (myodbc5.dll) A similar error occurs if I go through the rest of the wizard and perform the operation. The failed step is "Setting Source Connection" the error refers to retrieving column information and then lists the above error. It can retrieve column information just fine when I modify column mappings so I really don't know what the issue is. I've also tried getting various MySql tools to output ddl statements that SQL Server understand but haven't succeeded. I've tried with MySQL v5.1.11 to SQL Server 2005 and with MySQL v5.1.45 to SQL Server 2008 (with ODBC drivers 3.51.27.00 and 5.01.06.00 respectively)

  • Why does MS SQL Mgmt Studio Express keep forgetting my passwords?

    - by Ryan
    I have about had it with this tool, I check the save password box at the login dialogue but it just doesn't work. Sometimes it will for a few days, and then the password will just be gone. Nearly every time I load this thing up I have to track down the password again and type it in. Is there some password rule in the database that would be causing this? This is driving me absolutely crazy.

    I'm trying to drop a constraint on a db table, something like: ALTER TABLE MyTable drop CONSTRAINT FK_MyTable_AnotherTable But the execution just runs and runs.

Web search throws up various pages but note that the constraint is properly named and I am trying to remove it using the correct name

  • How do I use a concatenation of 2 columns in a SQL DB in ASP.NET properly?

    - by user293357
    I'm using LinqToSql like this with a CheckBoxList in ASP.NET: var teachers = from x in dc.teachers select x; cbl.DataSource = teachers; cbl.DataTextField = "name"; cbl.DataValueField = "teacherID"; cbl.DataBind(); I want to display both "firstname" and "name" in the DataTextField however. I found this solution but I'm using LINQ: http://stackoverflow.com/questions/839223/concatenate-two-fields-in-a-dropdown How do I do this?

  • Why are there performance differences when a SQL function is called from .Net app vs when the same c

    - by Dan Snell
    We are having a problem in our test and dev environments with a function that runs quite slowly at times when called from an .Net Application. When we call this function directly from management studio it works fine. Here are the differences when they are profiled: From the Application: CPU: 906 Reads: 61853 Writes: 0 Duration: 926 From SSMS: CPU: 15 Reads: 11243 Writes: 0 Duration: 31 Now we have determined that when we recompile the function the performance returns to what we are expecting and the performance profile when run from the application matches that of what we get when we run it from SSMS. It will start slowing down again at what appear to random intervals. We have not seen this in prod but they may be in part because everything is recompiled there on a weekly basis. So what might cause this sort of behavior?

  • With SQL can you use a sub-query in a WHERE LIKE clause?

    - by Jason
    I'm not even sure how to even phrase this as it sounds weird conceptually, but I'll give it a try. Basically I'm looking for a way to create a query that is essentially a WHERE IN LIKE SELECT statement. As an example, if I wanted to find all user records with a hotmail.com email address, I could do something like: SELECT UserEmail FROM Users WHERE (UserEmail LIKE '%hotmail.com') But what if I wanted to use a subquery as the matching criteria? Something like this: SELECT UserEmail FROM Users WHERE (UserEmail LIKE (SELECT '%'+ Domain FROM Domains)) Is that even possible? If so, what's the right syntax?

  • How do I iterate through hierarchical data in a Sql Server 2005 stored proc?

    - by AlexChilcott
    Hi, I have a SqlServer2005 table "Group" similar to the following: Id (PK, int) Name (varchar(50)) ParentId (int) where ParentId refers to another Id in the Group table. This is used to model hierarchical groups such as: Group 1 (id = 1, parentid = null) +--Group 2 (id = 2, parentid = 1) +--Group 3 (id = 3, parentid = 1) +--Group 4 (id = 4, parentid = 3) Group 5 (id = 5, parentid = null) +--Group 6 (id = 6, parentid = 5) You get the picture I have another table, let's call it "Data" for the sake of simplification, which looks something like: Id (PK, int) Key (varchar) Value (varchar) GroupId (FK, int) Now, I am trying to write a stored proc which can get me the "Data" for a given group. For example, if I query for group 1, it returns me the Key-Value-Pairs from Data where groupId = 1. If I query for group 2, it returns the KVPs for groupId = 1, then unioned with those which have groupId = 2 (and duplicated keys are replaced). Ideally, the sproc would also fail gracefully if there is a cycle (ie if group 1's parent is group 2 and group 2's parent is group 1) Has anyone had experience in writing such a sproc, or know how this might be accomplished? Thanks guys, much appreciated, Alex

  • How can I exclude LEFT JOINed tables from TOP in SQL Server?

    - by Kalessin
    Let's say I have two tables of books and two tables of their corresponding editions. I have a query as follows: SELECT TOP 10 * FROM (SELECT hbID, hbTitle, hbPublisherID, hbPublishDate, hbedID, hbedDate FROM hardback LEFT JOIN hardbackEdition on hbID = hbedID UNION SELECT pbID, pbTitle, pbPublisher, pbPublishDate, pbedID, pbedDate FROM paperback Left JOIN paperbackEdition on pbID = pbedID ) books WHERE hbPublisherID = 7 ORDER BY hbPublishDate DESC If there are 5 editions of the first two hardback and/or paperback books, this query only returns two books. However, I want the TOP 10 to apply only to the number of actual book records returned. Is there a way I can select 10 actual books, and still get all of their associated edition records? In case it's relevant, I do not have database permissions to CREATE and DROP temporary tables. Thanks for reading! Update To clarify: The paperback table has an associated table of paperback editions. The hardback table has an associated table of hardback editions. The hardback and paperback tables are not related to each other except to the user who will (hopefully!) see them displayed together.

  • How to synchronize two (or n) replication processes for MS SQL databases?

    - by Yauheni Sivukha
    There are two master databases and two read-only copies updated by standard transactional replication. It is needed to map some entity from both read-only databases, lets say that A databases contains orders and B databases contains lines. The problem is that replication to one database can lag behind replication of second database, and at the moment of mapping R-databases will have inconsistent data. For example. We stored 2 orders with lines at 19:00 and 19:03. Mapping process started at 19:05, but to the moment of mapping A database replication processed all changes up to 19:03, but B database replication processed only changes up to 19:00. After mapping we will have order entity with order as of 19:03 and lines as of 19:00. The troubles are guaranteed:) In my particular case both databases have temporal model, so it is possible to fetch data for every time slice, but the problem is to identify time of latest replication. Question: How to synchronize replication processes for several databases to avoid situation described above?

  • In SQL How do I copy values from one table to another based on another field's value?

    - by Joshua1729
    Okay I have two tables VOUCHERT with the following fields ACTIVATIONCODE SERIALNUMBER VOUCHERDATADBID UNAVAILABLEAT UNAVAILABLEOPERATORDBID AVAILABLEAT AVAILABLEOPERATORDBID ACTIVATIONCODENEW EXT1 EXT2 EXT3 DENOMINATION -- I added this column into the table. and the second table is VOUCHERDATAT with the following fields VOUCHERDATADBID BATCHID VALUE CURRENCY VOUCHERGROUP EXPIRYDATE AGENT EXT1 EXT2 EXT3 What I want to do is copy the corresponding VALUE from VOUCHERDATAT and put it into DENOMINATION of VOUCHERT. The linking between the two is VOUCHERDATADBID. How do I go about it? It is not a 1:1 mapping. What I mean is there may be 1000 SERIALNUMBERS with a same VOUCHERDATADBID. And that VOUCHERDATADBID has only entry in VOUCHERDATAT, hence one value. Therefore, all serial numbers belonging to a certain VOUCHERDATADBID will have the same value. Will JOINS work? What type of JOIN should I use? Or is UPDATE table the way to go? Thanks for the help !!

  • MSSQL / T-SQL : How to update equal percentages of a resultset?

    - by Kent Comeaux
    I need a way to take a resultset of KeyIDs and divide it up as equally as possible and update records differently for each division based on the KeyIDs. In other words, there is SELECT KeyID FROM TableA WHERE (some criteria exists) I want to update TableA 3 different ways by 3 equal portions of KeyIDs. UPDATE TableA SET FieldA = Value1 WHERE KeyID IN (the first 1/3 of the SELECT resultset above) UPDATE TableA SET FieldA = Value2 WHERE KeyID IN (the second 1/3 of the SELECT resultset above) UPDATE TableA SET FieldA = Value3 WHERE KeyID IN (the third 1/3 of the SELECT resultset above) or something to that effect. Thanks for any and all of your responses.

  • Does SQL Server guarantee sequential inserting of an identity column?

    - by balpha
    In other words, is the following "cursoring" approach guaranteed to work: retrieve rows from DB save the largest ID from the returned records for later, e.g. in LastMax later, "SELECT * FROM MyTable WHERE Id > {0}", LastMax In order for that to work, I have to be sure that every row I didn't get in step 1 has an Id greater than LastMax. Is this guaranteed, or can I run into weird race conditions?
