Inserts And Updates Question (newbie)...should Be Simple To Explain
Sep 6, 2005
Hello people!Here is the situation:We have an old propriatary database that is used for daily tasks. Not much we can do with it, but we have to use it.I can create basically a read only connection to it through ODBC.I would like to, on a timed interval copy certain data for reporting from this slow thing to my SQL server so that I can learn to program, and create some cool reports etc without having to wait on this server all day.So here is what I don't quite understand.I had originally planned on just deleting the contents of the tbl on my SQL server just before I populated it each time, but found out that my AutoNumber field will continue to increase, and I'm assuming that eventually I'm going to run into a problem as a result.Should I be doing some kind of update instead? if so do I need to first CHECK if the record exisit, if not then do an insert, if so do an update type thing?Or is there a way to basically do it in one command?I hope this makes sense. I would show you some code but there really isn't much to show you other than my insert statement :->Thanks for any advice!Josh
Can someone point me to some code that properly prepares a string for an INSERT or UPDATE into a char or varchar column? I need to be able to handle single & double quotes and any other possible issues. thanks
Hi... I have data that i am getting through a dbf file. and i am dumping that data to a sql server... and then taking the data from the sql server after scrubing it i put it into the production database.. right my stored procedure handles a single plan only... but now there may be two or more plans together in the same sql server database which i need to scrub and then update that particular plan already exists or inserts if they dont...
this is my sproc... ALTER PROCEDURE [dbo].[usp_Import_Plan] @ClientId int, @UserId int = NULL, @HistoryId int, @ShowStatus bit = 0-- Indicates whether status messages should be returned during the import.
AS
SET NOCOUNT ON
DECLARE @Count int, @Sproc varchar(50), @Status varchar(200), @TotalCount int
SET @Sproc = OBJECT_NAME(@@ProcId)
SET @Status = 'Updating plan information in Plan table.' UPDATE Statements..Plan SET PlanName = PlanName1, Description = PlanName2 FROM Statements..Plan cp JOIN ( SELECT DISTINCT PlanId, PlanName1, PlanName2 FROM Census ) c ON cp.CPlanId = c.PlanId WHERE cp.ClientId = @ClientId AND ( IsNull(cp.PlanName,'') <> IsNull(c.PlanName1,'') OR IsNull(cp.Description,'') <> IsNull(c.PlanName2,'') )
SET @Count = @@ROWCOUNT IF @Count > 0 BEGIN SET @Status = 'Updated ' + Cast(@Count AS varchar(10)) + ' record(s) in ClientPlan.' END ELSE BEGIN SET @Status = 'No records were updated in Plan.' END
SET @Status = 'Adding plan information to Plan table.' INSERT INTO Statements..Plan ( ClientId, ClientPlanId, UserId, PlanName, Description ) SELECT DISTINCT @ClientId, CPlanId, @UserId, PlanName1, PlanName2 FROM Census WHERE PlanId NOT IN ( SELECT DISTINCT CPlanId FROM Statements..Plan WHERE ClientId = @ClientId AND ClientPlanId IS NOT NULL )
SET @Count = @@ROWCOUNT IF @Count > 0 BEGIN SET @Status = 'Added ' + Cast(@Count AS varchar(10)) + ' record(s) to Plan.' END ELSE BEGIN SET @Status = 'No information was added Plan.' END
SET NOCOUNT OFF
So how do i do multiple inserts and updates using this stored procedure...
I have a number of columns with predefined character length but user can input more from gui. i want to trucncate automatically to the desired length and insert or update the database right now it does not allow me to update , or insert the values can i do it and how this is urgent
Using Trigger(After Insert) in tbl1 to insert the data of tbl1.Pid to tbl2.Pid and tbl3.Pid . tbl1 will be uploaded with new rows and existing rows will be updated from the csv file.
Trigger in tbl1 works fine by inserting data to tbl2.Pid and tbl3.Pid.
My questions are : 1. Is it possible to use trigger to update tbl2 and tbl3 if records exist if not insert new record to colum Pid in tbl2 and tbl3 from Pid of tbl1
2.Or is it possible to use sql procedure to do cascaded updates or inserts by merging datasets from tables and csv file using asp.net
3.Or How can I use single Trigger to insert if not exist and update if data exist.
4.Or Do I have to use two trigger one for insert and one for update. If this is the case how do check for data existance.
After insert Triger I am using at the moment is below (replied as an answer in this forum for my previous thread)
create trigger t1 on tbl1 after insert as begin declare @id int select @id=pid from inserted insert into tbl2(pid) values(@id) insert into tbl3(pid) values(@id) end
Hi, i have the following sp. im using vs.net2005, sqlserver2005.
now how do i implement functions like - > okay using datasets, exception is thrown that the row has been modified and i get to inform the user, reload the modified row, .
how do i get same functionality using sp? is that possible ? how/

I'm a relative novice on SQL Server and am a complete beginner at SQL, so am looking for a little help.
I currently use a DTS package to perform inserts / updates to a "production" table.
The DTS package transforms a comma separated file into a "temporary" table that is truncated / cleared before the load starts.
The temporary table has a column denoting Insert or Update. The production table is almost identical, however, doesn't contain the Insert / Update column. The DTS package then, depending upon the Insert / Update flag, either inserts data into the production table or updates data in the production table.
When the DTS package has completed, I'd like to be able to run an SQL Query that validates everything in the "temporary" table is identical to that in the "production" table, which it should be.
I have managed to do some queries to verify that everything has loaded / updated i.e. select primary_key from temporary table where primary_key not in (select * from production table), however, what I haven't been able to do is verify that all the columns on the temporary table match the values in the production table (excluding the Insert / Update flag).
I tried concatenating the columns in each table and comparing the concatenated values, however, this failed due to the different data-types, i.e. decimal, text etc.
I am looking for pros and cons for the following scenarios:
When a table contains a unique key constraint is it viable to always do an insert and immediately check the @@ERROR value and if @@ERROR states a duplicate key exception then perform an update statement?
Another possible solution would be to always check if the key exists and then do the insert / update based upon that result. This method will always require two steps.
We have a weird problem in our test SQL 2005 SP1 - Windows 2003 Enterprise SP1 - Server (after upgrading from SQL 2000).
While changing data via JBOSS - JDBC connection, we get all our data modifications rolled back.
Selects are fine. Same SQL 2005 Inserts/Updates through JBOSS are fine on other machines with Windows XP (JBOSS is on the same machine there, while in troubled configuration it's on its own server).
But in production imitation environment we can't modify data.
Hi,Before stepping into ado.net code to perform an insert or update, the insert / update has already taken place, just on starting the debugger. I use VS 2005 on SQL Server 2000. This did not happen with VS 2003 and SQL Server 2000.Anyone else encountered this?
I am kinda new with SQL and am trying to get a count of on the number of updates and or inserts to any given or group of tables and cannot get the syntax correct...can anyone help with this? Thank you in advance. Colin P.
Hopefully someone can at least point me in the right direction for moreresearch (e.g.: correct terminology). My only previous experience was justdumping data into a database using ODBC, and that was some years ago so nowmostly forgotten.I need to write an NT Service/Application (in C/C++) that will be gettingdata sent to it via SQL Server 2000. The data will arrive in my SQL Server(read-only access), via replication of tables from another remote SQLServer.My application needs know when new row are inserted, or updated so it can toread this data (needs to be quick/timely so hopefully no polling) to theninterface with other remote proprietary systems.T.I.A.PS: If you can recommend appropriate books on SQL Server 2000 that wouldalso be useful.
Hello,Can someone point me to getting the total number of inserts and updates on a tableover a period of time?I just want to measure the insert and update activity on the tables.Thanks.- Vish
I have transactional replication set up between two SQL Server 2000 databases. In some cases when I perform an UPDATE on a published table on the the publisher, SQL Server attempts to perform a DELETE followed by an INSERT on the subscriber using the stored procedures created during the initial snapshot.
Why does it do this?
How can I stop it doing this and force an UPDATE on the publisher to call the UPDATE procedure on the subscriber?
This managed application was written to run on a Symbol 3090 Win CE 5.0 scanning device. We are using the symbol provided classes to access the scanning interface, and SQL Compact database on the device to collect the scanned data, and then using merge replication to synchronize scanned data when the device is docked. The problem we have experienced seems to be releated to the performance when inserting and updating records in the database.
We have tested some randomly generated 1000 records and inserting/updatating into a database. At first the time to commit a record increases when the database is flushing into the memory (The flush interval in the connection string property is 10 seconds by default). and then as the database size grows increasing the time to commit every single record which is causing the application to perform slowly as they scan items into the database. However, the device program memory remains consistant as they are scan items. From our tests, I found the time to execute either a update/insert command on 2MB sqlMobile database (upto 10000 records, depending on the size of the columns) is taking nearly 2 to 2 and half seconds to complete. Below is the only code I am executing,
Hi, I have the following problem: Within a VBScript, I use a component (written in C++ I think with use of ADO) for sending "Insert", "Update" Statements to an SQL Server 2000 for inserting, updating data. If I insert 100 - 120 Records in a Loop, all works fine. If I insert 1000 records, approximately 150 records will be inserted very quick, then the program pause fo approx. 8 - 15 minutes and then it proceed for the next 150 recs, pause for 8 - 15 minutes and so on.
If I use a SQL Server 2005 for the database, all works fine. The same happens with another customer and another program written in Visual Basic 6.0 with ADO. The access to SQL 2000 pause and with SQL 2005 all works fine. It seems to me that this is a problem with some buffers, timeout, or so. Has anyone an idea on what screw I can turn?
Ok, I think this may have a simple answer. Basically I have no problems in setting up QueryString/Control/etc parameters when I use SELECT in the Configure Data Source Wizard as it prompts me for the necessary parameters. But when I try to use the Configure Data Source Wizard with an UPDATE, INSERT or DELETE it does NOT prompt me for the required parameters.Is this a bug or am I just missing something? Do I have to put them in manually or something?Thanks!
I have a 14GB database whose data content is legacy and is described as static. The log file is significantly large and continues to change size mostly increasing by 2-5GB a day (~60GB now) I have observed over the past two days; it shrank once unexpectly by a few GB. The instance is hosting other databases such as: EnterpriseVaultDirectory, EnterpriseVaultMonitoring, EnterpriseVaultStore, and NetPerfMon - might these seemingly unrelated data sources be involved?
I am trying to a trace to find traffic against the tables, no such luck.
Web applications are playing against it for queries but there should be no UPDATEs beign applied. I can only suspect that other unknown applications are performing operations but have yet to find unexplained connections.
Are there any other reasons why this type of log file activity would happen merely due to queries or stored procedure calls?
Lets also state, "mirroring, indexing, replication" are not at play. I know logging "Full" is not necessary as "Simple" should suffice but I am still hunting down why UPDATEs might be getting through. I realize I might adjust the migrated SQL 2000 security model to deny updates to find what breaks but would rather not take that iniative yet.
The installation is a fresh SQL 2005 Standard setup with SP2 applied; the databases were upgraded.
i want to provide an SQL query to set all the priority to 1 for all customers that have all their orders being for a product with importance of 100. Thank you in advance. Shcema---------------------------------------------------------------- There are three tables in the database: Customer, Product and Orders.
The Customer table has three column: Customer_id (PK), priority, Address.
The Orders table has three colums as well: Order_id (PK), Customer_id (FK), Product_id (FK)
The Product table has three columns as well: Product_id(PK), Product_name, Importance.
So the order table is connected to both the product and the customers table by respective foreign key.
I need a script that inserts the data of an excel sheet into a table. If something already exists it should leave it, unless it's edited in the excel sheet and so on and so on. This proces has to go through a stored procedure... ...But how?
We have a SQLServer 2005 Enterprise merge replication publication with SQL Mobile 3.0 subscribers (Windows Mobile 5.0 and 6.0). We do not use pre-computed partitions due to trigger performance issues with an SSIS/ETL application that supplies data to the merge database. We do use the "Optimize" (=true) option, though we have tried this both ways with no significant differences. We use filters and joins for each worker ID (as HOST_ID) from the subscriptions.
The sync times become increasingly worse after we run the snapshot and bring the publication online. I have tried rerunning the snapshots, this helps little, as it often behaves like the subscription was set to reinitialize and forces a big sync (reload of all data) to the subscriber. We have tried much of the obvious (e.g., flattening filters and joins, adding indexes, etc.).
When users are synchronizing, we watch replication monitor and notice that a lot of time is spent processing "enumerating inserts and updates for article [any article]", especially processing the many generations and batches. This is true for any follow-up syncs after the 1st big sync (initializing the subscription).
I read several posts regarding the batches and generations of changes, and decided to try increasing the €œDownloadGenerationsPerBatch€?. I tried adding this parameter to the snapshot agent job, and the job fails each time with a vague message, even with the default value of 100. How do you change this parameter for SQLServer 2005 Enterprise?
my database is on the attachment. Im decent with vb programming but suck with databases! Basically Ive to accomplish the following. I created code for a calendar that allow a user to enter a value for any date in the calendar. I need to take the values they entered into my vb calendar and save the dates with a value to my database. If I were working with one table it wouldnt be a problem. Unfortunately Im using ADO which only allows for 1 table connection at a time. To compensate for this i used 2 ado connections. 1 for each table. The details table shold store the date of an infraction for the employee(infraction-Date that employee screwed their attendance up by a no-call/no-show, coming in late, etc)
My problem is if an infraction is entered it might be the first time that employee got an infraction and i get an error because im moving both tables at the same time. I know basically im supposed to use an if exists clause for this and then next time the details page is available then re synchronize the tables according to employee id. My prob is I only know what it says in a book. Ive no practical experience. I guess what is like to see is a very simple vb program hooked up to a database with 2 table a main table and a details table. Then I would be fine As i can pick apart the code to see what it does.
Normally Id just attach my project as a whole but as thier are very complicated calculations in it, Im not yet done with my error checking for these calulations.
Also from what I do know of databases and structure I currently have my table setup correctly I wanted to verify that at this point and hopefully ...see a sample program of this as stated above.
I am a PHP/Delphi MySQL programmer for some years, now I am going to create some code in MS SQL and VB. So I downloaded and registered MS SQL 2005 Server Express Edition and some tools like SQL Server Studio Management Express, and VB 2005 Express.
As I have some knowledge of MySQL design and programming, I have installed MS software, rather without problems. Then, using Studio Management I created new database, new table in it with some four fields (int, varchars and smallint). Then from the same tool I opened table and inserted some data, and closed this application.
Next I opened Visual Basic and in Database Explorer I set up connection to my SQL database indicating the file it is stored in (path*.mdf). I ordered not to copy data to new file but to use original one.
Then in Data Sources I created new data source based on previously set connection. In the end I dragged and dropped my table from Data Sources into my new Form of my new Windows Application, nice grid with panel appeared. So I ran the app, I tried to put some data and then after trying to save (using floppy disk icon on panel) i got error: Update requires a valid UpdateCommand when passed DataRow collection with modified rows. which appears in event handler for saving in line i've indicated.
Me.Validate() Me.LudzieBindingSource.EndEdit() Me.LudzieTableAdapter.Update(Me.TestDataSet.ludzie ) ' <-- here highlights
I tried then to add to ID field identity specification, nothing changed. Then in query editor of management console I put some code: exec sp_configure 'user instances enabled', 1. Reconfigure.
As some sources mentioned. I restarted Service. Nothing Changed. So this is my problem. What to change.
I use Win XP Pro SP2.
And next one question, even more important for me is the way I connect to database. I found that in Visual Basic Creating new connection in Database Explorer I indicate the file on my local drive!!! And for example if I try to open my table alongside in Management Studio Express and in my App in VB and the error raises Cannot open user default database. Login failed. Login failed for user 'FS7120Mm227'. which is not a surprise for me as in VB i am using file which cannot be shared.
In MySQL I simply put address, port and so on and I could use my database in Delphi, PHP, and another management tools with no hassle. Is it possible in VB? Or it only can be used to exclusive using database?
Please inform me if such questions shall be directed to VB forum, I am not sure, and thank you for _any_ answer.
MS goes right way giving people great possibility to use and even sell small apps using their Express Editions of SQL and VB, but it is still too confusing for people who encouraged start using their apps and have such basic problems.
Hello, I am taking a Database course this semester and I am totally clueless on the general concepts of managing a database. I have a few questions about these two tables. If someone could please answer them and maybe explain it to me I would greatly appreciate it!...and yes it is homework but I really want to understand it!
1.Which column or columns contain redundant data?
2.Why would you want this duplication, give an example of a use of this database that would benefit from redundancy.
3.Give an example of a specific constraints you would place on programs that accessed this database to control the redundancy?

Heya Everyone !I am new in Asp.net - I've read tutorial at this page, but i have some problems.I want to have a login form at my website. I also want that login form is checking if user is in a user table (database). I mean simply login form - you write login and a password, than click button - site execute query (select * from user_table where user_id=login and user_password=password or something like this). But I have a problem with building this all code with sql connections. Can someone tell me how can I send query to my sql database ? And how can I display it? And once more - how set the cookies, but thats the other problem.
I have a project that consists of a SQL db with an Access front end as the user interface. Here is the structure of the table on which this question is based:
Code Block
create table #IncomeAndExpenseData ( recordID nvarchar(5)NOT NULL, itemID int NOT NULL, itemvalue decimal(18, 2) NULL, monthitemvalue decimal(18, 2) NULL ) The itemvalue field is where the user enters his/her numbers via Access. There is an IncomeAndExpenseCodes table as well which holds item information, including the itemID and entry unit of measure. Some itemIDs have an entry unit of measure of $/mo, while others are entered in terms of $/yr, others in %/yr.
For itemvalues of itemIDs with entry units of measure that are not $/mo a stored procedure performs calculations which converts them into numbers that has a unit of measure of $/mo and updates IncomeAndExpenseData putting these numbers in the monthitemvalue field. This stored procedure is written to only calculate values for monthitemvalue fields which are null in order to avoid recalculating every single row in the table.
If the user edits the itemvalue field there is a trigger on IncomeAndExpenseData which sets the monthitemvalue to null so the stored procedure recalculates the monthitemvalue for the changed rows. However, it appears this trigger is also setting monthitemvalue to null after the stored procedure updates the IncomeAndExpenseData table with the recalculated monthitemvalues, thus wiping out the answers.
How do I write a trigger that sets the monthitemvalue to null only when the user edits the itemvalue field, not when the stored procedure puts the recalculated monthitemvalue into the IncomeAndExpenseData table?
Hi there I sorry if I have placed this query in the wrong place. I'm getting to grips with ASP.net 2, slowly but surely! When i try to access my site which uses a Sql Server 2005 express DB i am receiving the following error:

The database is definitly in the folder that the error message relates to. What I'm finding confusing is that the connection string seems to be finding "aranga"s database. Is it something daft?
why do the following return the same datasets? select * from myTable where myData = '' select * from myTable where myData = ' ' in the first I'm specifically searching empty strings, in the second a sequence of five spaces. Yet both return any and all white character matches? Is this a "feature" of SQL... P.S. I'm using T-SQL
Until a few days ago we didn't even know SPID 1 existed. These are different guys, using old version of Crystal passing crappy queries.
Here's the scenario SPID 1 is running (inefficient select) SPID 2 is waiting 30 minutes pass and SPID 2 is still waiting PAGEIOLATCH_SH SPID 3 fires off
Now SPID 2 is blocking SPID 3, but SPID 2 is still waiting for SPID 1
Finally when SPID 1 finishes, everything catches up. But it appears that there is a period of at least 45 minutes when all SPID's are just sleeping.
My questions: 1. If SPID 1 is just running an inefficient select query, why is it holding up SPID 2 (Which reads and inserts). SPID 1 should have a shared lock on table, this would prevent SPID 2 from insert/update? 2. Is there any steps I can take to give SPID 2 precendence? or is it first come first serve?
