I have got 4 MS Access Database Files, which have got 3 Tables each, means Total 12 Tables which gets updated with new data every evening, by an external application. Means new data gets appended to all these 12 Tables.
I want to have exact same 4 Databases, which have got 3 Tables each, means Total 12 Tables, but WITHIN MS SQL SERVER. And then update all of these 12 Tables every evening, with the corresponding updates from the respective tables from the MS Access Databases.
What are the various options to get this kind of work done in SQL Server. I do not want to Manually Update all these 12 tables every evening into SQL Server. Hopefully there would be some easier method to do this in automatic manner.

I'm changing data storage for an asp.net project from MS Access to Sql Server. I've got the web site working, but I need to update the sql server tables with data from our Oracle db daily. What is the "best" way to do that?
I've read about DTS, but have never done anything like that. Would it be worth the time and effort to study? (So far I've created a package, with the import wizard, that doesn't work & I don't have the authority to delete :-)
I know I could create a dataset with my Oracle data and use that to update sql server. But is there a way to schedule an aspx to run authomatically? Would this affect performance? The sql server db isn't very big (30-40,000 records), but the Oracle db is & I need to do quite a bit of manipulation to the data.
This is new to me & I'm don't know what I should be searching for to find help. And if there is a more appropriate place to post this question, please let me know.
I want to send auto email to my subscribers(no. of subscribers always vary) This auto email has to be send daily. Could it be done by generating certain Stored Procedure ? if yes then please help me by providing Stored Procedure.
Given the below table relationships, I am trying to update the price of disk by %20 percent that were interpreted by 'Joe Smith'. I took a crack at this, but I do not feel comfortable with it. Do I need to do some type of join or union?
UPDATE Disk SET price = price *.20 WHERE Interpreter.name = ‘Joe Smith;
Table1(T1) contains Column1 (C1) which must be appended to Column2 (C2) in Table2 (T2) where an identifying code column(ID) matches in each table. An example of what I want is, where T1.C1 = 'Aluminum' and T2.C2 = 'Material', I would like it to be updated to T2.C2 = 'Material: Aluminum'. I tried this:
UPDATE T2 SET T2.C2 = (SELECT T1.C1 FROM T1 WHERE T1.ID = T2.ID) + ':' + T2.C2
Hi,I tried to use the following query to update a value in one table witha value from another table:UPDATE tbl1SET col1 = tbl2.col2FROM tbl1, tbl2WHERE tbl1.[id] = tbl2.[id]but it won't work. I also tried this with a subquery using "TOP 1",but that wouldn't work either. SQL Server 2000 gives me the followingerror-message:"Subquery returned more than 1 value. This is not permitted when thesubquery follows =, !=, <, <= , >, >= or when the subquery is used asan expression.The statement has been terminated."What is wrong? It seems that the join is not functioning properly, butit functions properly with a rather 'simple' SELECT. How to updatethose fields, other than by hand ;)Regards,Falco Vermeer
I have multiple product tables with a "ListPrice" column. I want to use a temporary table that contains "ProductID" and "ListPrice" columns and execute a stored procedure that will update the "ListPrice" column in all product tables with the "ListPrice" from temporary table where "ProductID" from temporary table matches "ProductID" in product tables.
Conditional Update of a field from multiple tables..I have a target table with two fields: Date and ID..There three source tables: S1, S2, S3, each of them has three fields: Date, ID, and Score...Now I want to update the target table: put the ID into the ID field which has the highest Score from the three tables on each day.
I am trying to run an update statement against a vendor's database that houses HR information. If I run a regular select statement against the database with the following query, it returns without error:

I am assuming I am receiving this error because it doesn't know where to find QUDDAT-INT? How can I fix that?
The "QUDDAT-INT" column houses the employee number. So in the case of the SELECT query above, I am testing against a specific employee number.
Hi, I have a Users table in Oracle database and same table (Users) in SQL Server 2000 database. I want to create a DTS Package through which I can copy the data from Oracle database to SQL Server 2000 database. This package should run automatically at mid-night daily so that if there are some entries done in Oracle database then it get copied in SQL Server 2000 database. Also is there any way to copy only those entries from Oracle database which are not present in SQL Server 2000 database. Please help me in this regard as I am new to DTS.
Hi! I have a general SQL CE v3.5 design question related to table/file layout. I have an system that has multiple tables that fall into categories of data access. The 3 categories of data access are:
1 is for configuration-related data. There is one application that will read/write to the data, and a second application that will read the data on startup.
1 is for high-performance temporal storage of data. The data objects are all the same type, but they are our own custom object and not just simple types.
1 is for logging where the data will be permanent - unless the configured size/recycling settings cause a resize or cleanup. There will be one application writing alot [potentially] of data depending on log settings, and another application searching/reading sections of data. When working with data and designing the layout, I like to approach things from a data-centric mindset, because this seems to result in a better performing system. That said, I am thinking about using 3 individual SDF files for the above data access scenarios - as opposed to a single SDF with multiple tables. I'm thinking this would provide better performance in SQL CE because the query engine will not have alot of different types of queries going against the same database file. For instance, the temporal storage is basically reading/writing/deleting various amounts of data. And, this is different from the logging, where the log can grow pretty large - definitely bigger than the default 128 MB. So, it seems logical to manage them separately.
I would greatly appreciate any suggestions from the SQL CE experts with regard to my approach. If there are any tips/tricks with respect to different data access scenarios - taking into account performance, type of data access, etc. - I would love to take a look at that.
I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian
Table 1 - dbo.DimHC_Team - This stores TeamID and TeamName Table 2 - dbo.DimHC_Team_Config - This has TeamID TeamDate (not really used anywhere) TeamHeadCount (Max strength of a team)
Table 3 - dbo.DimHC_Team_Agg - This has TeamID, Team_Date (1st of every month, so that when I see the data for past months I use these dates) , Permanent Employees, Contracted employees, Open positions, Total, HeadCount.
Now, I have a stored procedure which goes like this -
if (not exists (select * from dbo.DimHC_Team_Agg where Team_Date = @datevar2)) begin
insert into dbo.DimHC_Team_Agg (TeamID, Team_Date) select TeamID , @datevar2 from dbo.DimHC_Team_Config end
update dbo.DimHC_Team_Agg set Team_Head_Count = dbo.DimHC_Team_Config.Team_Head_Count from dbo.DimHC_Team_Config, dbo.DimHC_Team_Agg where dbo.DimHC_Team_Agg.Team_Date = @datevar2 and dbo.DimHC_Team_Config.TeamID = dbo.DimHC_Team_Agg.TeamID
update dbo.DimHC_Team_Agg set Perm_Posn = (select count(EmpType) from dbo.uview_DimHC_Emp_view1 where EmpStartDate < = @datevar4 and EmpType = 'Permanent' and (EmpEndDate = '01/01/1753' or EmpEndDate > @datevar3) and TeamID = '1'), Contract_Posn = (select count(EmpType) from dbo.uview_DimHC_Emp_view1 where EmpStartDate < = @datevar4 and EmpType = 'Contractor' and (EmpEndDate = '01/01/1753' or EmpEndDate > @datevar3) and TeamID = '1') ......
What this block is doing is converting today's date to the first of this month. Going one month and 2 months in advance. Then it checks if any employee's start date < 10th of the next month and end date > 31st of the next month and if both the conditions are met then increments the employee count for that team as 1.
This TeamID is then repeated for 13 teams that I have right now. So that every month I will run it and it will update.
Now, I have 2 problems - First being that I had to write this block for 13 teams which isn't really a smart thing to do. Let's say I add a team tomorrow then I will need to modify this stored procedure and then tomorrow I may not be here, so the person who uses it should be able to do it easily. So, I wanted to know if I can loop or something through this with the max limit of TeamID coming from some external source and not like fix it to 20 or something.
Second, let's say in the beginning of this month I add a new team. The way I will do it is I will add it to dbo.DimHC_Team and dbo.DimHC_Team_Config table. Now, if I run this stored procedure then
if (not exists (select * from dbo.DimHC_Team_Agg where Team_Date = @datevar2))
is not going to return NULL as there will be entries with some teams right now. So this new Team won't be inserted in the dbo.DimHC_Team_Agg table and I will have to manually do it.
Can somebody help me as to how can I get over with these two problems?
Sorry for being really long but I thought it best to give all the details.
I'm using SQL 7, there is a setting on DB properties called "Auto update statistics", what kind of statistics does this refers to and how can this stats be accessed?
Does anyone know how to tell how long it took for an auto update statistics to run? I looked under DBCC Show_Statistics and it shows the time the stats were last updated, but not how long it took to update them. Thanks.
We are using SQL Server 2005. The auto update statistics and auto create statistics for a database is set to ON. This database has a very heavy work load. When I checked the individual statitics , still the last updated statistics is in a old date value (few months ago).
Is it necessary to manually update the statistics for the same database? Or can we rely upon "auto update statistics" itself ?
Usually in what frequency the manual UPDATE STATISTICS should be run on production system which has heavy transactions ?
I have been working on a Human Resource Management software in C# .NET. In its Employee Attendance module i need to keep records of attendance of all workers for one month in a single table.The problem I encounter is to auto generate an exact copy of the Attendance table after a particular month is finished. How can i accomplish this? I use SQL server 2008.
Recently a production server suffered a critical blocking period and I wanted to know if I could solicit some input. It seems that a stored procedure was in the middle of recompiling while and auto update statistics started. This caused blocking for like an hour on the single object (stored procedure) that was originally called. The table that the update occurred on and that the stored procedure is reading form is quite large. It is 2 mil rows and about 140 columns wide. Some info from sysprocesses is below. The table alone takes up almost 4GB of space, when looking at sp_spaceused. I have some questions. 1. Can the update statistics for a '_WA%' stats cause blocking on a table? 2. Does an update stats on an index survive a restart of SQL server? We tried restarting, but the blocking did not end. 3. If the stored procedure is running under a compile, can the server automatically start an update stats and cause the stored procedure to wait? 4. Can the server automatically start an update stats on more than one column stats at a time, causing one to be blocked by the other? 5. We had never seen this issue before going to SQL2K clustering. Is this something specific to SQL2K and not SQL7 ?
Thanks for your input. John Lee

How can I set a column in a table to auto update the date and time everytime something in that row is updated or when the row is first added? Thanks ahead for the help,Jason
Hi guys,I followed the ASP.net official tutorial to create a DAL & Business Logic Layer (http://www.asp.net/learn/dataaccess/tutorial02cs.aspx). I have a table with a int ID field. I wish to write a function to add a new entry into this table but have the ID field auto-increment.The ID field is set as the Identity Column and has a Identity Increment & Seed of "1". If I manually go to the table and insert a new record leaving the ID value null it automatically increments. But if I create a C# function to add a new entry I get an error saying that the ID field can't be Null. Is there any way to use the Update method as shown on line 14 below to add a new entry but with it automatically incrementing? I did create a function called InsertDevice that simply inserts the other fields using a SQL INSERT and it auto-increments fine, just wondering if there is a way to do it using the DataTable and the Update method? Thanks for any help!!! 1 public bool AddDevice(string make, string model) 2 { 3 //cannot have the same device entered twice! 4 if (Adapter.FillDeviceCountByMakeModel(make, model) == 1) 5 return false; 6 7 RepositoryDataSet.DevicesDataTable devices = new RepositoryDataSet.DevicesDataTable(); 8 RepositoryDataSet.DevicesRow device = devices.NewDevicesRow(); 9 10 device.make = make; 11 device.model = model; 12 13 devices.AddDevicesRow(device); << Error thrown Here! 14 int rows_affected = Adapter.Update(devices); 15 16 return rows_affected == 1; 17 }
Hi, I use the SqlDataSource Control for generating SQL-statements that I easily can modify. But on some tables I cant autogenerate the statements for Insert, Delete and Update. The checkbox is dimmed/not enabled. Why cant I use the autogenerate feature on some tables?
For my company, we have made it a standard to create history tables and triggers for the majority of our production tables. I recently grew tired of consistently spending the time needed to create these tables and triggers so I invested some time in creating a script that would auto generate these.
We recently launched a project which required nearly 100 history tables & triggers to be created. This would have normally taken a good day or two to complete. However, with this script it took a near 10 seconds. Here are some details about the script.
The code below creates a stored procedure that receives two input parameters (@TableName & @CreateTrigger) and performs the following actions:
1) Queries system tables to retrieve table schema for @TableName parameter
2) Creates a History table ("History_" + @TableName) to mimic the original table, plus includes additional history columns.
3) If @CreateTrigger = 'Y' then it creates an Update/Delete trigger on the @TableName table, which is used to populate the History table.

Just when I though I knew what I was doing. I ran into a roadblock.I have two tables, organizations & usersI am building a form online for orgs to input their own information.How do I insert into both tables when the org table needs to know what theuser_id is, but the user_id hasn't been created until the form is submitted?Any help or request for additional info would be more than great.Thanks!
Over the past week and a half we started experiencing a sporadic slowdown in our production x64 SQL 2005 Ent. Edition server. Users started complaining of slowness then they started getting timeouts. In looking at sp_who2 and perfmon we saw the following during the slow/frozen periods: * Dramatic increase in Perfmon Active Transactions * CPU higher than norm, but not dramatically so * sp_who2 shows a number of spids in SUSPENDED state (and not running waits) * no blocking indicated from sp_who2 * active connections slowly increasing * no disk queuing (or at most some spikes to 1) After a couple of minutes of this we would then see the following: * no more spids in SUSPENDED state * Logins per second spikes dramatically * Active transactions spikes down to "normal levels" * CPU goes high then levels out at moderately higher than normal * active connections slowly decreases back towards normal levels * large spike in lock wait time
We turned on the Async Auto Update Statistics option (after testing in our staging environment) on the primary database about a week before we saw this problem. By turning it off we can visually see the problem go away by watching the above metrics. So my question is, What metrics can I use to see the "blocking" or resouce locking that is causing these problems? Anyone? Thx Ron
hi there, i am new to sql server database.i am doing small projects right now using asp.net and sql to create webpages (very basic webpages) My problem is:
Problem :
i have two tables .....table 1 and table 2.
Table 1 has following fields: studentid,student name,student address.
Table 2 has following fields:studentid and course . table1 student id is the primary key refrencing table 2 student id. Now i delete a record in table 1 which will in turn also get deleted in table 2 . so for eg if i have three records 1 ,2 and 3 ....then i delete 2 in table 1 ...i will have 1 and 3 in both table 1 and table 2....now i want 3 to become 2 in both table 1 and table 2...so that i dont have empty space between two student id's 1 and 3. so this is my problem....if any one can help me out with suggestions please do.
