(SQL Mobile)Can SELECT, But Cannot INSERT/UPDATE. Why Not?
Sep 27, 2006
I'm just getting started with using SQL Server Mobile while creating a handheld app using Visual Studio 2005. So far, I have succeeded in RETRIEVING data from the mobile database, but I don't understand why my INSERT nor UPDATE statements will not work. (I'm assuming they don't work, because after I run my code via the debugger, I oddly get no error message, but when I "open" the table in the Server Explorer, I do not see my expected results. Do I need to do some kind of "commit" or something? Here's my code. Thanks for any help! - Sue

'Create SQL statement:
Dim strSQL As String
strSQL = "INSERT INTO MyTable (col1, col2) VALUES ('yucky', 'poo')"
'Create DB connection:
Dim connDB As New System.Data.SqlServerCe.SqlCeConnection
connDB.ConnectionString = ("Data Source =" _
+ (System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly.GetName.CodeBase) + "SueUWM.sdf;"))
'Create DB command:
Dim cmndDB As New System.Data.SqlServerCe.SqlCeCommand(strSQL, connDB)
'Open the connection:
connDB.Open()
'Execute the command:
Dim intRecordsAffected As Integer
Try
intRecordsAffected = cmndDB.ExecuteNonQuery()
If intRecordsAffected <> 1 Then
MessageBox.Show("Unable to insert into database.")
End If
Catch ex As Exception
MessageBox.Show(ex.ToString, "Insert Error")
End Try
Is it possible If I use insert query to insert a record, but the record is already exist, it will automatically change insert to update?
And
I have a row: customer_name, last_update
is it possible to use sql to check if the customer_name I want to update is the same as the customer_name in database, it can automatically stop the update?
Am trying to find a way to insert/update/delete data in a SQL mobile database on a Windows CE 5.0 device FROM a desktop PC.
This situation is completely stand alone, no network (apart form device/desktop), no GPRS etc etc etc.
I've looked at RDA but i dont believe it fits my app. (pulling data from a 2005 server that doesnt exist doesnt really help me much, push can't be used without a pull which kills the idea.)
The goal is a UI on the desktop that can manipulate data in the SQL mobile Database.
I've tried all i can find/think off in relation to this but to no avail.
My latest attempt has been using the simplest method possible (using a VS wizard datasource to the devices DB and tryign to whack that on a form) but this just creates a "Path not found. Check the directory for the database [Path = Mobile Device/ce_swipe/TestDB.sdf".
I've got four pages with in the first page a insert, in the second a select, in the thirth a update and in the fourth a delete statement. First the values of a textbox will be inserted in the database, then the values will be shown in labels and than it is possible to edit or delete the values inserted. Every inserted item belonging to each other has one ID. The follwing values has a second ID etc. How can I make that possible?? I think that I should pass the ID's between the pages so I'm sure that I edit or delete the values that I want. So insert value 1 in page 1, show with select value 1 in page 2, edit or delete value 1 in page 3 and 4. Maybe I didn't explain it good enough for you, please tell me then!! Thanks!!
hi i have form view that retrieves a single row i dont want to use SQLDataSource default Select/Update/Insert/Delete buttons i am using Stored Procedures I want to have my own buttons, the select has parameters, how to retrieve data for that parameter?
Hi everyone..i m new to this field.. can anyone explain me with simple example onhow to insert,update,select data from the sqldatabase? i m using vwd 2005 express edition along with sql express edition. plz explain the simple example with code (C#) including how to pass connection strings etc.thank you.jack.
Dim cn As New System.Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("LocalSqlServer").ToString())
cn.Open()
Dim adapter1 As New System.Data.SqlClient.SqlDataAdapter()
adapter1.SelectCommand = New Data.SqlClient.SqlCommand("update aspnet_Membership_BasicAccess.Products set id = '" & textid.Text & "', name = '" & textname.Text & "', price = '" & textprice.Text & "', description = '" & textdescription.Text & "', count = '" & textcount.Text & "', pictureadd = '" & textpictureadd.Text & "', artist = '" &textartist.Text & "', catergory = '" & textcategory.text & "' where id = " & Request.Item("id") & ";", cn)
cn.Close()
Response.Redirect("database.aspx")
it posts and the page loads but the data is still the same in my datagrid. what could be wrong with this simple statement... i've tried testing the statement above with constant values of the correct type but i don't think that matters because the SqlCommand() accepts a string only anyways.. doesn't it?
Greetings. I have been trying to develop an SSIS package that updates external data (Visual FoxPro tables) from SQL Server 2005. I have tried this various ways: using various Data Flow task components that flow to an OLEB Destination; using an Execute T-SQL Task; and even trying Management Studio interactively with the OpenDataSource('vfpoledb', etc.) statement. For each of these techniques, I have no problem performing a SELECT from the VFP data. Also, I have no problems performing an INSERT of new records using any of these techniques. However, both UPDATE and DELETE of existing records fail.
Is it possible the the OLE DB driver doesn't support UPDATE and DELETE operations? It appears that I'm not allowed to change or delete existing records, only add new ones. Or, are there other techniques I can be trying?
I am aware that updating FoxPro data can be performed by pulling the data from SQL Server into FoxPro. For our purposes, it would be more convenient if the processes could be initiated and managed from the SQL Server side of things instead.
Hello All I have had asked the same question in another post, i didnt get answer to it i might have had asked it wrongfully
Soo the question is: When creating a SQLDataSource in the wizard you get to the pont where you select the option . It says that by using this datasource you can select to update delete and insert. So my question is if i am creating a select statement to reterieve the data from the Table, then what does it do it do if my intention is to only reterie the data. Or what is the other way that it could be helpful to me ??
thanks all I hope it make sence, if not I wrill write another post to bring step by step info into it.
Hi All, As known its recommended to use stored procedures when executing on database for perfermance issue. I am thinking to create 4 stored procedures on my database (spSelectQuery, spInsertQuery, spUpdateQuery, spDeleteQuery) that accept any query and execute it and return the result, rather than having a number of stored procedures for all tables? create PROCEDURE spSelectQuery ( @select_query nvarchar(500) ) as begin
exec sp_executesql @select_query, N'@col_val varchar(50) out', @col_val out
We have a rather large environment and have just a couple of boxes out there that we are getting cannot begin distributed transaction on inserts and updates but works fine on selects. Inserts and updates work fine outside the begin tran / commit so it's definitely DTC
We have checked the configuration on and the source box is set to No authentication required same for destination.
We have: Verified credentials running the service, changed them, same problem. Uninstalled and re-installed MSDTC per Microsoft instructions.
Have run all the tools for checking DTC DTCPing etc and followed those procedures which typically in the past has resolved any DTC issues. Other than swapping out the offending pc for a new one we are at a loss.
Hello, I recently view a webcast of sql injection, and at this moment I created a user, and give dbo to this user, and this same user, is the one I have in the connection string of my web application, I want to create a user to prevent sql injection attacks, I mean that user wont be able to drop or create objects, only select views, tables, exec insert,update, deletes and exec stored procedures.
Is any easy way to do this?
A database role and then assing that role to the user?
I have a GridView dispalying from a SQLServerDataSource that is using a SQL Select Union statement (like the following):
SELECT FirstName, LastNameFROM MasterUNION ALLSELECT FirstName, LastNameFROM CustomORDER BY LastName, FirstName I am wondering how to create Update and Insert statements for this SQLServerDataSource since the select is actually driving from two different tables (Master and Custom). Any ideas if or how this can be done? Specifically, I want the Custom table to be editable, but not the Master table. Any examples or ideas would be very much appreciated! Thanks, Randy
I am inserting updating few tables from snapshot and reading same bunch of tables from reporting using readcommitted . It is showing some deadlocks i think it is write in this situation as " x" is not compitable with "s" ,"is".
i am using visual web developer 2005 and SQL 2005 with VB as the code behindi am using INSERT command like this Dim test As New SqlDataSource() test.ConnectionString = ConfigurationManager.ConnectionStrings("DatabaseConnectionString1").ToString() test.InsertCommandType = SqlDataSourceCommandType.Text test.InsertCommand = "INSERT INTO try (roll,name, age, email) VALUES (@roll,@name, @age, @email) " test.InsertParameters.Add("roll", TextBox1.Text) test.InsertParameters.Add("name", TextBox2.Text) test.InsertParameters.Add("age", TextBox3.Text) test.InsertParameters.Add("email", TextBox4.Text) test.Insert() i am using UPDATE command like this Dim test As New SqlDataSource() test.ConnectionString = ConfigurationManager.ConnectionStrings("DatabaseConnectionString").ToString() test.UpdateCommandType = SqlDataSourceCommandType.Text test.UpdateCommand = "UPDATE try SET name = '" + myname + "' , age = '" + myage + "' , email = '" + myemail + "' WHERE roll 123 " test.Update()but i have to use the SELECT command like this which is completely different from INSERT and UPDATE commands Dim tblData As New Data.DataTable() Dim conn As New Data.SqlClient.SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Database.mdf;Integrated Security=True;User Instance=True") Dim Command As New Data.SqlClient.SqlCommand("SELECT * FROM try WHERE age = '100' ", conn) Dim da As New Data.SqlClient.SqlDataAdapter(Command) da.Fill(tblData) conn.Close() TextBox4.Text = tblData.Rows(1).Item("name").ToString() TextBox5.Text = tblData.Rows(1).Item("age").ToString() TextBox6.Text = tblData.Rows(1).Item("email").ToString() for INSERT and UPDATE commands defining the command,commandtype and connectionstring is samebut for the SELECT command it is completely different. why ?can i define the command,commandtype and connectionstring for SELECT command similar to INSERT and UPDATE ?if its possible how to do ?please help me
In my C# code I have a Class property that takes the value DateTime.Min upon initialisation, but when I try to insert this into the database column (yes, it is DateTime data type :)) I get an 'Unexpected Error' from SQL Server Mobile.
I have use this guide to make a application for windows mobile 5.0. http://msdn.microsoft.com/vstudio/tour/vs2005_guided_tour/VS2005pro/Smart_Client/DataBinder.htm Everything is work. I can add, remove data in the dataset. But i can't update the sql server database. can somebody tell me whats wrong? Nitro.
Hiya, last one (for a while), I swear. I'm getting the hang of this now (famous last words).
I've got a data file saved as an image type in my SQL Mobile database, and I'm trying to send it over to my SS2005 Server via RDA, which seems the simplest way possible. The application will only have periodic rows to send over and insert into the Server's DB, so it seems like doing a merge or a push is unnecessary overhead.
Is there some way to include parameters in the SQL string argument to the method SubmitSQL? Or, embed the byte array into the SQL string? For the life of me, I can't figure out how to do this.
So, if column data has type image, my statement would look like what?
I need to do a Select and after a Insert during a Transaction. But when i want to commit this transaction i've the following error message :
The transaction can not be committed if there are any opened cursors in the scope of this transaction. Make sure all data readers / result sets are explicitly closed before committing the change.
I don't understand this error message. How can i close my cursors.
Before my Insert i'm closing my SqlCeDataReader and i dispose it. My SqlCeCommand are also closed and dispose.
I have created a database in the SQL Server 2005 and the same database in sql mobile. I have a field, which has a GUID and uniqueidentifier, when i tried to insert the same data which is there in sql server 2005 database into sql mobile database it is giving me error as below
Major Error 0x80040E14, Minor Error 25501
> INSERT INTO TypeValue (TypeValue_ID,DisplayValue,TypeName,OrderIndex,IsActive)
I was using Visual Studio 2003 and SQL Server CE 2.0 for C# mobile applications. The .sdf database were created in the emulator or in the mobile device itself using Query Analizer.
The application developed need some initial data to run, and this data is obtained executing one service that reads a postgree database, and insert the data in the SQL CE database of the mobile device. But, given the size of the database (maybe 10.000 rows), it tooks too much time (sometimes 6 hours).
Now we are migrating to Visual Studio 2005 and SQL Server 2005 Mobile Edition.
I want to know if its possible to create the .sdf database and load the data into this database on the desktop. Maybe through the execution of a .sql script, or through a service executed on the desktop.
After this, its just upload de .sdf file to the mobile device.
If I have a table with 1 or more Nullable fields and I want to make sure that when an INSERT or UPDATE occurs and one or more of these fields are left to NULL either explicitly or implicitly is there I can set these to non-null values without interfering with the INSERT or UPDATE in as far as the other fields in the table?
EXAMPLE:
CREATE TABLE dbo.MYTABLE( ID NUMERIC(18,0) IDENTITY(1,1) NOT NULL, FirstName VARCHAR(50) NULL, LastName VARCHAR(50) NULL,
[Code] ....
If an INSERT looks like any of the following what can I do to change the NULL being assigned to DateAdded to a real date, preferable the value of GetDate() at the time of the insert? I've heard of INSTEAD of Triggers but I'm not trying tto over rise the entire INSERT or update just the on (maybe 2) fields that are being left as null or explicitly set to null. The same would apply for any UPDATE where DateModified is not specified or explicitly set to NULL. I would want to change it so that DateModified is not null on any UPDATE.
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded) VALUES('John','Smith',NULL)
INSERT INTO dbo.MYTABLE( FirstName, LastName) VALUES('John','Smith')
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded) SELECT FirstName, LastName, NULL FROM MYOTHERTABLE
I have a web form with a text field that needs to take in as much as the user decides to type and insert it into an nvarchar(max) field in the database behind. I've tried using the new .write() method in my update statement, but it cuts off the text after a while. Is there a way to insert/update in SQL 2005 this without resorting to Bulk Insert? It bloats the transaction log and turning the logging off requires a call to sp_dboptions (or a straight-up ALTER DATABASE), which I'd like to avoid if I can.
I'm working on inserting data into a table in a database. The table has two separate triggers, one for insert and one for update (I don't like it this way, but that's how it's been for years). When there is a normal insert, done via a program, it looks like the triggers work fine. When I run an insert manually via a script, the first insert trigger will run, but the update trigger will fail. I narrowed down the issue to a root cause.
This root issue is due to both triggers using the same temporary table name. When the second trigger runs, there's an error stating that a few columns don't exist. I went to my test server and test db and changed the update trigger so that the temporary table is different than the insert trigger temporary table, the triggers work fine. The weird thing is that if the temporary table already exists, when the second trigger tries to create the temporary table, I would expect it to fail and say that it already exists.I'm probably just going to update the trigger tonight and change the temporary table name.
I don't understand why I am having this error. It does create the database on AddSubscription() method but it is failing opening the database on Synchronise(). I have also tried uninstalling and then reinstalling all the SQL Mobile components in the following order.
Hello,I am writing a stored procedure that will take data from severaldifferent tables and will combine the data into a single table for ourdata warehouse. It is mostly pretty straightforward stuff, but there isone issue that I am not sure how to handle.The resulting table has a column that is an ugly concatenation fromseveral columns in the source. I didn't design this and I can't huntdown and kill the person who did, so that option is out. Here is asimplified version of what I'm trying to do:CREATE TABLE Source (grp_id INT NOT NULL,mbr_id DECIMAL(18, 0) NOT NULL,birth_date DATETIME NULL,gender_code CHAR(1) NOT NULL,ssn CHAR(9) NOT NULL )GOALTER TABLE SourceADD CONSTRAINT PK_SourcePRIMARY KEY CLUSTERED (grp_id, mbr_id)GOCREATE TABLE Destination (grp_id INT NOT NULL,mbr_id DECIMAL(18, 0) NOT NULL,birth_date DATETIME NULL,gender_code CHAR(1) NOT NULL,member_ssn CHAR(9) NOT NULL,subscriber_ssn CHAR(9) NOT NULL )GOALTER TABLE DestinationADD CONSTRAINT PK_DestinationPRIMARY KEY CLUSTERED (grp_id, mbr_id)GOThe member_ssn is the ssn for the row being imported. Each member alsohas a subscriber (think of it as a parent-child kind of relationship)where the first 9 characters of the mbr_id (as a zero-padded string)match and the last two are "00". For example, given the followingmbr_id values:1234567890012345678901123456789021111111110022222222200They would have the following subscribers:mbr_id subscriber mbr_id12345678900 1234567890012345678901 1234567890012345678902 1234567890011111111100 1111111110022222222200 22222222200So, for the subscriber_ssn I need to find the subscriber using theabove rule and fill in that ssn.I have a couple of ideas on how I might do this, but I'm wondering ifanyone has tackled a similar situation and how you solved it.The current system does an insert with an additional column for thesubscriber mbr_id then it updates the table using that column to joinback to the source. I could also join the source to itself in the firstplace to fill it in without the extra update, but I'm not sure if theextra complexity of the insert statement would offset any gains fromputting it all into one statement. I plan to test that on Monday.Thanks for any ideas that you might have.-Tom.
suggested that this problem could be circumvented by getting the replication object early and then continuously using the same object for subsequent replications.
I did this and it works a lot better now but ever so often I get another error which is
Native Error 28559 SQL Mobile encountered problems when opening the database
My only option at this point is to stop and start the application which cures the problem.
I am developping a non-managed C++ application for PocketPC using a SQL Server mobile database.
The application is compiled for PocketPC 2003 and uses SQL Server Mobile v2. I use Visual Studio 2005. But I need to compile the application for Windows Mobile 5.0 devices. So I installed the WM5 SDK and had the WM5 into my project configuration.
The "ssceoledb.h" which I include incluses the "transact.h" file. But my problem is that this file is only provided with the PocketPC 2003 SDK and not in the WM5 SDK. So I cannot use the WM5 configuration project with SQL Server. I also tried with the last SQL Server Mobile 2005 (ie v3.0) and the "ssceoledb30.h" also includes "transact.h".
Did I miss something to install ? Do you know how I can resolve the problem ?
