Thank you for reading this. I am faced with a problem where there is no storage of deleted or updated information in an OLTP DB. I am mostly concerned about retrieving the deleted data from a table when an update occurs so as to make the deleted data show as an error. Is there a way to retrieve these kind of data from a DB, if so how? Can these data be retrieved by dates? Also how much time do you have before the data can no longer be retrieved? Assuming that the data can be retrieved.
I know the good stuff about datawarehousing but unfortunately we have no DW. Any help will be greatly appreciated.
We've got a merge replication. I have one Publisher and one Subscriber. I've made a pull subscription to a Publisher.
I've got into trouble few times occasionally 3-4 times a year. Today also I got problem with one table only one row among so many not carried out on at subscriber, even it is not find out at publisher.
This row was entered at subscriber in the morning, printed by users but in evening report it is not coming down in reports, so I had checkup and find out it is not available at any server. How?
I don’t understand, how inserted, printed data erase from subscriber but rarely. Is there any clue?
Which parameter of the subscription is responsible for it ?
I have a database that is 70GB big. One of the tables has over 350million rows of data. I need to delete about 1/3 of the data in thatone table.I was going to use a simple delete command to delete the unnessacaydata.Something likeDelete from tablename where columname > '100'However, it takes SOOO LONG to run, over 8 hours, if not longer....What is the best way to delete this data???One idea was to create a Temp Table, then move the needed data to thetemp table, then Truncate the Table, and move that data back.I'm not very good with SQL Query Language, so can somone give me anexample on how to do this?? Or if you have a differant idea that wouldbe faster please let me know.thanks,Sam
I have created a asp.net web api hosted on Azure. A couple of times a day all data from my database get deleted and I see these errors in the log. I have tried to reinstall microsoft sql server spatial types from nuget, but that didnt work. Could not load assembly 'D:homesitewwwrootbinSqlServerT ypesx86SqlServerSpatial110.dll'.
Error received: 'Could not load file or assembly 'file:///D:homesitewwwrootbinSqlServerTypesx86SqlServerSpatial110.dll' or one of its dependencies. The module was expected to contain an assembly manifest.'.
"I meant to delete just one assignment, doing which was giving me difficulty.
I deleted a whole category by accident which had most of my daily grades in it for a course with quite a few of them. I was negligent in backing them up, so I cannot restore them. I have an XLS file from the midterm, but am missing about 6 grades after that.
Is there any way to recover the grades I had in the deleted category. It has been a couple of days since I entered any new grades. HELP!"
My current backup strategy is to do a full backup 5 pm, differentials every 2 hours, logs every 30 min, all so they arenot simultaneous. Backing these all to same backup device via three different jobs.
Then the server is backed up to tape shortly after the 5 pm full backup.
Obviously, I can't restore from the backup for this situation because it would hurt other data.
But - is there a way I can take last night's backup from tape and restore it to a different database than our production database? (Such a database doesn't at this time exist. Would I detach, copy over the files, and then reattach on prod and attach on the devl side, and then restore from the backup device to the devl copy?)
I've never had to perform this kind of rescue and am wondering if my backup strategy is flawed since it isn't immediately evident how I can easily do this.
I needed a similar thing from our Oracle DBA yesterday, and he went to tape, copied out a table and put it on the Oracle database under a different owner, and I easily fixed the few records that I had botched.
That's exactly what I need to do now with MS SQL 2000.
I was hoping someone would be able to help me, I trying to go through several databases, 111 to be exact, and get the data out of a particular table which is present in all the databases on the same server.
I know how to get the names of the databases from the INFORMATION_SCHEMA, but how can use the name for it to cycle through all the databases and get data out of the one particular table.
Hi, I need some help. I have this query where i need to pull up students that have more than or equal to 3 absences in a row. Now I am getting all those students that are absent but not in a row. But i was wondering if there is a way to tell if a student was absent three days in a row . There is a date field that is being used to identify the day of the class and a status field that identifies if the student was absent or present. Please help someone.
Up to the moment I've got enough knowledge for read data stored into .LDF files by dbcc log and so on. It's very useful and interesting. Now, I wonder how to retrieve the same information but on MDF files.
At first, I want to make sure that is not possible by mean of traditional methods (dbcc or something like that) I suppose so but I'd like to hear opinions regarding that.
Thanks in advance for any idea, though or further information.
I have an older instance of SQL Server (2000) used for an old installation of Great Plains. Over the years there have been several custom application built to interface various accounting related systems with the data on this server.
Recently there have been several instances where random transactions are being deleted. The folks in the accounting group setup Great Plains to track any deletes from the GL account and determine who did the deletes. They're telling me that the same account we use to launch SQL Server is the account deleting the data.
It's possible that someone knows the login creds for this account and is using it to do some task that's causing the problem, but that's a long shot in my opinion. I rather believe that one of these custom interface apps is causing the problem.
One of the custom interfaces includes several SQL jobs that run that do some truncating and bulk inserting. In each case these jobs are owned by the sa account. If one of these jobs deleted the data would it be reported as being deleted by sa or by the service account since that's the account that launches SQL Server Agent?
I accidentally deleted some useful data in my database. I have both .LDF and .MDF files for this database. Is there a way to recover this database to a point of time? Thx.
this is a simple problem but it's just driving me mad as it's not reading from my dB. basically, I've have reviews stored in my dB and want to display them in a textbox by clicking on a button called btnReviews. I think the problem might be that there is too much text stored per row of the table (as it is a review), but I have the datatype set as text in sql. here's the simple un-errorred code I have behind the button. any ideas where I went wrong. i've a feeling it's something small but it's just taken too long to figure out.protected void btnReviews_Click(object sender, EventArgs e) { String strConn = ConfigurationManager.ConnectionStrings["conLocalDatabase"].ConnectionString; SqlConnection dbConnection = new SqlConnection(strConn); SqlCommand dbCommand = new SqlCommand("Select [ReviewC] From [Review])", dbConnection); dbCommand.Parameters.AddWithValue("Review", txtReviewView.Text); try { dbConnection.Open(); dbCommand.ExecuteNonQuery(); } catch (SqlException ex) { Console.WriteLine(ex.ToString()); } finally { if (dbConnection != null) { dbConnection.Close(); } } }
Hi I ve a datagrid . And Two Database table in sqlServer2005. The name of the tables are 'Property' and 'userid'. My datagrid wants to retrive all records from Property table and one record from userid table. The Property table contains Propertycode, lastdate , departmentname. The userid table contains so many record along with 'id' record which my datagrid wants to retrieve. pl tel me how 2 write code for that?
I have four tables that need to be loaded into an ASP.NET application. They need to be loaded together into one result set and sorted. Is it possible to load four tables together and sort them using an SQL statement?
I am aware of and am using the SELECT ... ORDER BY feature of MSSQL in my present ASP.NET application to retrieve from single database tables. I'm using merged datasets and a sort method to solve the above problem at the moment.
I'm preparing a report that will display provider number, provider name, and a single field that will show all the counties that specific provider serves. I realize from researching the coalesce posts that this can be done. However, when I try to retrieve data in the same select statement as my coalesce, I get the error: "A SELECT statement that assigns a value to a variable must not be combined with data-retrieval operations."The listing of the counties must be specific to the provider, so my original code was:
DECLARE @Counties varchar(1000) SET @Counties = '' SELECT a.PROV_ID, a.PROV_NAME, @Counties=coalesce(@Counties,'') + b.COUNTY + ',' from ECBH.dbo.tbl_PROVIDERS a inner join ECBH.dbo.tbl_Provider_Serv_Regions c on a.PROV_ID = c.PROV_ID inner join ECBH.dbo.tbl_Regions b on b.REGION_ID = c.REGION_ID where c.PROV_ID = a.PROV_ID and a.MASTER = 1
I thought about creating a table to hold the coalesced values (need to coalesce two other fields as well), but wouldn't an insert to a table fail for the same reason?The counties table does not relate to the provider table, but does relate to a provider_county table (which in turn relates to the provider table).
I want to extract a particular portion of primary key field data.For example- suppose there are fifty data in PK field starting from 1...50.Now I want only to extract data from 25 to 50.It is bcos I want to retrieve only the new data that is inserted after a specified time.For example-today there is data starting from 1 to 25 which I have retrieved and saved elsewhere.By tomorrow there will be new data starting from 26 to 50 or more.Now I just want to extract this additional data from the database so that I dont need to extract all data again.Could anybody pls tell me how to do this.How can I do it using common SQL bcos I have to make a program for it.

I am working on a project on PocketPC in which it is required to reteive data from database. I have created database on simulator as .sdf file. I want to retreive data from eVC++ code. How i can do so?
Hi to all,I made a database using SQL Server 2005 and now I want to interact with that database through VC++ 2005. Is that possible?? If so, how can I do it?
I am trying to retrieve only the first few characters (12 to be precise) from this string that is coming in from FoxPro to SQL Server 2005 and I am coding in C#. I have tried these methods (after reading it in a book, as I am new to this) but it still gives me an error saying that the field cannot exceed 12 characters.
I have been thinking of using SQL server 2005 as i would like the flexibility i get through UDT. Retrieving the UDT data in managed could is ok but i would like to retrieve it in non .NET languages too.
For example lets say i create a UDT "Point". I insert data in a table that has some columns of type point.
Now is there a way i can get the data of the type point in a point object in non .NET languages like perl, python...
I am using Visual Studio 2008 with .NET 3.5 Visual Basic. I'm having a problem retrieving data from my SQL CE database. I have a function that imports a file, parses it and writes the contents to a database. When I then query the database from my code, the data I have just written doesnt seem to be there. Even when i close and re-run the program. Only when I first view the table contents through Visual Studio then re-run the program does the data show up.
The things I know are. When I insert data there is no problem. I can view the data through visual studio server explorer. only when I view data through the server explorer can my code retrieve it.
Could this be something to do with caching? Any help would be appreciated. The (stripped down) code I use to insert data is below
kevin
Dim rowsAffected = 0
Dim connection As New SqlServerCe.SqlCeConnection(connectionstring) Dim transaction As SqlCeTransaction
' command objects for inserting a ContactList and retrieving its last identity Dim cmdInsertContactList As New SqlServerCe.SqlCeCommand("INSERT INTO ContactLists (Name, FolderID) VALUES (@Name,@FolderID)") cmdInsertContactList.Parameters.Add("@Name", SqlDbType.NVarChar) cmdInsertContactList.Parameters.Add("@FolderID", SqlDbType.NVarChar)
' insert a new list cmdInsertContactList.Parameters("@Name").Value = list.Name cmdInsertContactList.Parameters("@FolderID").Value = folder.ID rowsAffected += CInt(cmdInsertContactList.ExecuteScalar())
I have not used the copy objects wizard that much. I used it today to copy 4views from my dev box to production. It copied the views, but also wiped outmy data in all the tables that the views are built around!!! Inproduction!!!!Can someone provide me some insight into why this happened?Thanks,Chad
When I reinitialized a subscription from SQL2005 db (publisher) to a SQL 2000 DB (Subscriber) and had the Upload changes before reinitialization turned on, the data from the SQL 2000 db didn't get uploaded. This resulted in a loss of 2 days worth of data.
Does anyone have any idea if there's anywhere that data is kept. (unfortunately a series of errors caused our backups to not be running on the 2000 db either).
Hi, I have an SSIS package that runs each day from a live data source to create a data mart, which is then used for various things including SSAS and SSRS.
The problem is that certain records that will eventually go on to form fact tables are deleted from the live system (not a very robost database in the first place, hence the SSIS!) but these are not reflected in the SSIS transformation, creating plus figures when compared to the live system.
I currently use type 1 slowly changing dimension processes in each data flow (of which there are about 35) but I realise that this only updates records and does not delete.
The solution I have in place is to truncate the fact tables in the mart before the run starts using an Execute SQL task. This solves the problem though to me seems a little heavy-handed and renders the slowly changing dimension processes redundant (as it is currently only run once a day).
My question is, is there a better method of dealing with the above scenario? If there isn't, it would be a nice feature to add to future versions (*nudge nudge*).
