How Can I Copy The Content Of MS Access Table In Database SQL Using Visual Studio Basic
Sep 26, 2007
Code Snippet
Hi there,
I'm struggeling for more than a week now with this problem, without a finding the solution.
I have two databases, MS Access and SQL Server 2005 Express Edition
Using a procedure in Visual Studio i would like to copy all the records from one table in MS Access into an existing table in SQL Server (the tables have the same name and the same layout)
I tried to prepare one Dataset to copy from Access into SQL Server but when i run the command 'DaSQL.Update(DsSQL, "Tabella") nothing happens (not even an exeption has been raised), looking during debug, the DataSet seems filled though...
Please could anyone explain what's wrong and / or is there a more quicker way to copy data from a table to another?
Note i woul have as a final goal to get data from an AS400 database by ODBC, manage it, and put it on SQL Server for a 'data mining' scope (eliminating the use of MS Access, not suited for FE-BE).
the procedure goes like this;
' Create a connection to the MS Access Database
Dim connectionToAccess As New OleDbConnection(DBConnectionAccString)
strsql = "SELECT * FROM [TABELLA]"
connectionToAccess.Open()
Dim DaAccess As New OleDbDataAdapter(strsql, connectionToAccess)
Dim DsAccess As New DataSet("ACCESS")
DaAccess.FillSchema(DsAccess, SchemaType.Source, "Tabella")
DaAccess.Fill(DsAccess, "Tabella")
' Create a connection to the SQL Database
Dim connectionToSQL As New SqlConnection(DBConnectionSQLString)
connectionToSQL.Open()
Dim DaSQL As New SqlDataAdapter(strsql, connectionToSQL)
Dim DsSQL As New DataSet("SQL")
DaSQL.FillSchema(DsSQL, SchemaType.Source, "Tabella")
DaSQL.Fill(DsAccess, "Tabella")
I am building a Visual Sudio process that will Truncate and load data to an Access database (2010) from SQL Server (2012). I have one "Execute SQL Task" for one table (LungCancer_HF_Patients):
"DELETE LungCancer_HF_Patients.* FROM LungCancer_HF_Patients;" that parses and works.
I have another table (Report1):
"DELETE Report1.* FROM Report1;"
that does not parse with a message "The query failed to parse. Incorrect syntax near '*'."
Why the first one parses correctly and the other one does not?
I am working in an access data project. I have a stored procedure that runs fine when I open and run it directly in sql. When I use the DoCmd.OpenStoredProcedure method in VB code, the stored procedure also runs fine (and successfully adds records as it should) but then I get an error: #7874 "...can't find the object...'[Name of sp'". This halts the vb code and is a problem. Here's example code from a sp that causes this problem:
Insert into Table (Field1, Field2, Field3, Field4) Select Field1, 'Test', Field5, GetDate() from View1
I understand there may be another syntax to run a stored procedure from access visual basic other than DoCmd. I would very much appreciate guidance as to how to do this.
I am new to this type of programming and and have read all articles on adding an image to the database and it seems they all use sql queries to add an image but I want to add an image at design time. I am using Visual Basic 2005. I am also using Visual Basic 2005 Express Edition to try the same thing. I am trying to build a Translator program for english to Brazilian Portuguese and the reason I want to add the images is so that when I translate the word cat from english to Portuguese, I can also show an image of a cat. Can anyone please help me

=========================================================== I ran the above project in VB 2005 Express and I got the following 5 errors: 1. Name 'EXEC' is not declared (in Line 16 of Form1.vb) 2. Method arguments must be enclosed in parentheses (in Line 16 of Form1.vb) 3. Name 'sd-insertNewRecord' is not declared. (in Line 16 of Form1.vb) 4.Comma, ')', or a valid expression continuation expected (in Line 16 of Form1.vb) 5. Expression expected (in Line 16 of Form1.vb) ============================================================ I know that "EXEC sp_insertNewRecord 6, 'Craig', 'Utley', '5577 Baltimore Ave',
'Ellicott City', 'MD', '21045', 'CraigUtley@yahoo.com' "in Line 16 of Form1.vb is grossly in error. But I am new in doing the programming of T-SQL in VB 2005 Express and I am not able to change it.
Please help and advise me how to correct these problems.
Of all the Visual Basic.NET data access books that I have purchased and all the Internet site example code that I have reviewed, none have had any good examples of multi-threaded VB.NET code doing data access.
I am trying to avoid the non-responsiveness in a VB app while a simple data retrieval from SQL Server 2005 is in progress.
If anyone knows of any book titles or web sites that have example code (good or not) of multi-threaded VB.NET applications doing data access against Microsoft SQL Server (7, 2000, or 2005) or even against Microsoft Access(TM), it would be very much appreciated if you could provide the book title or URL to point me in the right direction.
Hi all,need advice on the following task:copy the content of a big table from DB_A to DB_B in the same serverthe size of table:~ 7 million rows, ~ 9G in size, 1 clustered pk index, 13 nonclusteredindexcurrent practice:use DTS to copy the data, takes over 20 hours as-- first had to delete existing data of the table in DB_B-- then copy-- all these happen while all indexes are in place.I am trying to check what is the best or most efficient way to copythis kind of data and what wouldbe the expected time for such load.my machine: SQL 2000 Enterprise, 8-way P4, 12G RAM on a EMC Clarrion600 SAN.
Hi, I'm using SQL Server 2005 Management Studio Express. I have a database used for an application and I need another copy of that database so I can fix some bugs. I tried attaching the mdf to the second database but it gives an error.(a database is allready attached) I need the 2 databases on the same server.
Let me get VERY specific. This site has 40+ pages Using VWD 2008 (Studio 2008) I have created in local IIS7 (129.0.0.2) http://cumc.lcl Navigation.master, Web.config and Web.sitemap alll are structured And all 40+ pages have been built. NOW I added (using VWD) a sql server database named pagedata.mdf With a table named: pages and fields: PageID - Primary Key (auto numbered) pagename - nchar(30) exmp Default hitcount - numeric(18,0) createdate - nchar(15) exmp 04/18/2008 updated - nchar(15) similar to createdate hitdate - nchar(15) similar to createdate bottom of each page is to show 99999 visitors and under that is to be Updated on mm/dd/yyyy On pageload should accomplish the following increment the hitcount field and save it and display it in HitLabel.text Set UpdateLabel.text to updated field Save the date the page was hit in hitdate field. (will only show when last hit)
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
End Sub </script>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server"></asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server"> <p align="center">This page is for various tests<br />and will NOT be site mapped.</p> <p align="center"></p> <p align="center">
Can this SqlDataSource be moved into Sub Page_load above? How do I extract, process and save the Hit and Date data for each individual page referenced by pagename field? <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStringsageConnect %>" SelectCommand="SELECT * FROM [main] WHERE ([pagename] = @pagename)"> <SelectParameters> <asp:QueryStringParameter Name="pagename" QueryStringField="thispage" Type="String" /> </SelectParameters> </asp:SqlDataSource> </p> <p align="center"> <asp:Label ID="HitLabel" runat="server"></asp:Label> Visitors<br /> Updated on <asp:Label ID="UpdateLabel" runat="server"></asp:Label> </p> </asp:Content>
I have a database in my "App_Data" folder of my visual studio project. I can view it fine in Visual Studio's built-in tools for managing a database attached to a solution. However i recently started playing around with the SQL Server Management Studio Express program. When i attach my database to Management Studio, and try to run my program it crashes. I think it might be a permissions error?!? When i detatch it and reattach it in visual studio it runs fine again. Any suggestions? ThanksJason
When you work with Visual Basic 2005 Express Edition on windows XP, and if your application contains references to SQL-databases, I have discovered that it is important that all identities be logged off before you open the particular identity where you want to work on your Visual Basic project. I have earlier assumed that it was only possible to work with Visual Basic on one identity, the one where the version was registered.
This assumption was not quite correct. Actually, you may run Visual Basic applications with SQL-references on all identities on XP, provided that no other identities that are using the SQL-server are currently running.
For example, suppose you start your computer and log on the identity James. Then you switch identity, but you actually don't log off James. Then you log on the John identity. There you discover that it is impossible to create a new SQL-database in Visual Basic's Data-connections view. An error message appears. Why is that? It is because the SQL-server is busy on the James-identity. To solve this problem you want to log off the John identity, don't just switch. Then log on the James identity again, and log off properly. All identities should now be logged off. Now you may log on the John identity again, and it is now possible to create an SQL database.
Concerning deploying applications for XP. This issue is similar to the one I just described. You cannot run the installation-file successfully on one identity if the SQL-sever is busy on another identity. You want to log off all identities before logging on the identity where you want to install the application. Same thing when you want to run the deployed application.
Question. Does this limitation exist only in the express-editions of Visual Studio 2005 as a drag on free-ware, or is it prevalent in commercial editions as well? I would like to know a little more about this before purchasing the standard or professional edition of Visual Studio 2005.
I have created a database under management studio and i want it to be connected in visual studio but it failed the error msgs said that the database can't be connected coz the database with same name exits but that is not true
I have an application written with Visual Basic Express 2008, which has a Sql Server Express Compact database incorporated into the application. I've been trying to follow the suggestions listed on several threads on how to backup up my database and have not gotten very far. The following code seems to be in most threads.
Dim dbstring = "Data Source=.SQLExpress;Integrated Security=true;User Instance=true;AttachDBFilename=|DataDirectory|ImmuLogDataBase.sdf"
Dim sqlconn As New SqlClient.SqlConnection(dbstring)
sqlconn.Open()
When run, this code returns the following error at the sqlconn.Open() command.
An attempt to attach an auto-named database for file G:ImmuLogImmuLoginDebugImmuLogDataBase.sdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
My solution is saved on a flash drive which I take between home and work. I'm hoping that that isn't the issue. I believe that Visual Basic loads the database when it starts and it is already open when this code is run. Is there a way to access this open database and run a backup procedure on it from within VB express 2008?
I'm new to this and self taught so explain everything in detail. Thanks for your help. Bruce
How do i get the database that i am using in visual studio into my SQL server management studio? i need to create some scripts to create stored procedures on a live server.
Hi, i am new to sql server and visual basic, i need to connect my sql server database to a new application i've developed in visual basic 2005 express. Can any one tell me the steps to do this. Many Thanks.
I go to Server Explorer, right click on Data Connection, input the server name (that is, my own computer), give a new name to the database to create, and then inevitably get the error window saying:
An error occurred while establishing a connection to the server. When connectiong to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL server does not allow remote connections. (Provider: Named Pipes Provider, error 40, could not open a conection to SQL Server)
So, how to open a connection to SQL server 2005? I looked in the msdn but found absolutely nothing.
I am not able to see the Data Source in Visual studio 2012. I have tried several things like 'Alt + shift + D' which is meant to bring up the datasource tab but it does not. I have also looked in view->Other windows but its not displayed there.
I just found that the content of my Database "ssmsExpressDB" is gone, but the name "ssmsExpressDB" remains in the Object Explorer of SQL Server Management Studio Express. If I delected the name "ssmsExpressDB" and executed the following .sql:
Unable to open the physical file "C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDatassmsExpressDB.mdf". Operating system error 32: "32(The process cannot access the file because it is being used by another process.)".
And I have closed all my projects and I do not know what " The process cannot access the file because it is being used by another process" is all about!? Please help and tell me how I can re-attach the content of my "ssmsExpressDB" in the Object Explorer of SQL Server Management Studio Express.
I found the "ssmsExpressDB" is being used by my VB 2005 Express project "Hello-SQLCLR-1": in the Database Explorer, Data Connections place. How can I put it back to the Object Explorer of SQL Server Management Studio Express? Please help and advise.
I'm using an ObjectDataSource in Visual Studio to retrieve records from a SQL Server 2005 database. I have a very simple dilemma. In a table I have fields FirstName, Surname, Address1, Address2, Address3 etc. None of these are mandatory fields. It is quite common for the user not to enter data in Address2, Address3, so the values are <null> in the SQL table. In Visual Studio 2005 I have an aspx form where users can pass search parameters to the ObjectDataSource and the results are returned according to the passed in parameters. The WHERE clause in my Table Adapter is:WHERE (Address1 LIKE @Address1 + '%') AND (Address2 LIKE @Address2 + '%') AND (Address3 LIKE @Address3 + '%') AND (FirstName LIKE @FirstName + '%') AND (Surname LIKE @Surname + '%') If, for example, I simply want to search WHERE FirstName LIKE ‘R’, this does not return any results if the value of Address3 is <null> My query is this: Could someone please show me the best way in Visual Studio 2005 to return records even if one of the Address fields is <null>. For reference, I have tried: Address3 LIKE @Address3 + '%' OR IS NULLThis does work, however itsimply returns every instance where Address3 is <null> (accounting for about 95% of the records in the database). Thanks in advance Simon
When I try to create a database that will have fields for a date and a time the only data type option in visual studio is datetime. This stores data as dd/mm/yyyy-00.00.
how can I set it to store either a date dd/mm/yyy or a time 00.00 but not both.
I am working with VS version .0.50727 and .Net froamwork 2.0.50727.
Database under Options is set to SQLEXPRESS. In SQL Server configuration Manager, SQLEXPRESS is running and has all except VIA enabled.
When I try to add a new SQL data base to a project, I recieve the message 'Failed to generate a user instance of SL Server due to a failure in starting the process for the user instance. The connection will close.
Can someone help me with setup between VS and SQL serve?
I've installed ADS on a windows mobile 5.0 device and am trying to run the sample Wizard application. It connects to the test database on the device OK, but fails to connect to the database on the desktop with the error: "The HTTP request failed due to incorrect format or content. Try restarting the IIS server"
I've tried changing the port from 1024 in case it was already in use, but this doesn't change the error. Nor does restarting IIS (v5.1). IIS appears to be running correctly on the desktop.
I'm using Visual Studio 2005 Standard. I have an .mdf database inside my Visual Studio "Server Explorer" under "Data Connections." How do I script out this database, including the stored procedures in it? In other words, I want to export a SQL script that will create this database. I'm very much a newbie when it comes to working with database management. I thought I created this .mdf inside my local install of SQL Server 2005 Express, but maybe I did it somehow inside Visual Studio in the Server Explorer. When I open up SQL Server Management Studio Express I don't see this database. I did locate the .mdf on my local C drive but I haven't been able to get Mgt Studio to open it.
I have a Visual Basic Windows Project and am connecting to an SQL database. I drop a few of the tables from a DataSet onto a Windows form, and I want to scroll through (using the bindingnavigatror) and subsequently save the data if I decide to make changes to it. However, when I click on the save button it doesn't do anything. From the code, the save button is supposed to run this:
I can't connect to a SQL Server 2000 database using Visual Studio 2008. When I try to create a SqlDataSource in Visual Studio the db server isn't in the dialog box. When I manually create a connection string it doesn't connect. When I go to the server, the db is running and apps that use it work fine. I can ping the server, and I can map a drive to it, but I just can't connect to the database. I tried using servername,port - didn't work. I open SQL Server 2005 Management Studio and try to connect. In the Connect to Server dialog box, when I go to the Server Name dropdown and browse for my database server on the network, the server is not in the list. I tried entering the server name (and password, etc) but it doesn't connect. A different SQL Server 2000 database server does show up there.
