Defining Command,commandtype And Connectionstring For SELECT Command Is Not Similar To INSERT And UPDATE

Feb 23, 2007

i am using visual web developer 2005 and SQL 2005 with VB as the code behind
i 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 same
but 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

Select Command Done Similar To Insert?

Aug 2, 2007

I did a successful Insert to a SQL Server today in .NET VS2005.
But before I insert I figure I better make sure the part does not allready exist in the table.
Can a check the command to determine if it has a boolan value of False and if so to INSERT as before?  Dim myCommand As New SqlClient.SqlCommand

myCommand.CommandText = "Select PartNumber From Pricing Where PartNumber = '" & var0 & "'"

'myCommand.CommandText = "INSERT INTO Pricing (PartNumber, ListPrice, PartDescription, ProductClassCode, ProductClassDescription, ProductFamilyCode, ProductFamilyDescription, ProductLineCode, ProductLineDescription) VALUES('" & var0 & "', " & var1 & ", '" & var2 & "', '" & var3 & "', '" & var4 & "', " & var5 & ", '" & var6 & "', '" & var7 & "', '" & var8 & "')"

myCommand.Connection = con


con.Open()
myCommand.ExecuteNonQuery()
con.Close()

Insert-Select Command

May 21, 2001

I need to move various records from a production database to an archive database. The fields in the two databases are identical but the archive database has an additional "Transfer Date" field. Can anyone recommend an easy way to create an SQL statement to move the record from production to archive? I've tried

INSERT INTO ARCHIVE (SELECT * FROM PRODUCTION WHERE ACCOUNTNO='XYZ')

but I get an error saying the columns among the two tables do not match (obviously because of the "Transfer Date" column). Is there a way to use a similar SQL statement that will populate the "Transfer Date" column w/ today's date?

Thanks in advance for your help.

Update Requires Valid Insert Command

May 27, 2007

I have created a dataset in code with a select command being a stored procedure. I have used commandbuilder so as to create update, insert statements. The update of the dataset receives error "update requires valid insert command".



From reading, it seems the problem is that the select statement is a stored procedure so data adapter cannot created the insert, update commands.



Can I create an update and insert command using update and insert stored procedures and use those to update the dataset (with multiple records of course) or do I have to create my select command using a select statement rather than the stored procedure?





Thanks for any help on this

COMMAND SIMILAR TO SPOOL IN ORACLE

Jan 16, 2002

Hi all,
I have a table with the list of tables I need to drop. So basically before droping those tables I need to disable the FK and PK constraints.
So I want to spool out the out of this script.
SELECT 'ALTER TABLE ' +
QUOTENAME( c.TABLE_NAME ) +
' NOCHECK CONSTRAINT ' +
QUOTENAME( c.CONSTRAINT_NAME ) AS ALTER_SCRIPT
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS AS c
WHERE CONSTRAINT_TYPE = 'FOREIGN KEY'

Is there a way to store the output of this script in a .sql file so that I could execute it.
Any thoughts will help!
Thank you!

Command Text Was Not Set For The Command Object Error

Hi. I am writing a program in C# to migrate data from a Foxpro database to an SQL Server 2005 Express database. The package is being created programmatically. I am creating a separate data flow for each Foxpro table. It seems to be doing it ok but I am getting the following error message at the package validation stage:

Update Command Does Nothing

Aug 10, 2006

I have a database on a server that im trying to update using asp.net.  I tested this on another server and everything worked perfectly.  The test system was set up where the website is hosted.  But the live system is placed on a different server than the webpage.  Does that make a difference? 
Test System
Client -> Website/database
Live System:
Client -> website -> database
I created a user account to use when accessing the database on the live system because i read the double hop causes problems.  By using that account i can access and view the data.  But whenever i update it nothing happens.  NO ERROR either.  It works perfectly but does nothing.  Anyone have any ideas please?!?!?!

Hi all, just need a LITTLE help here.  I am very close, I know I am, but just can't seem to fit the last piece in on this.  I have a page that shows current data for a customer and allows you to make changes to the data, then I have a button to push to update the system.  If I hard-code in a value in place of '@Pf_Value' it will update that value, so I know my where is working, just SOMETHING missing in syntax on the set statement or something wrong on my cmd.parameters statement.  Any help would be great!!Protected Sub UpdateButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles UpdateButton.Click
Dim sql As String = "update CustomerPOFlexField set [Pf_Value] = @Pf_Value where Pf_property = 'Attrib1' and Pf_CustomerNo = @CustomerNo"Dim newc As String = NewCustomer.Text

Update Command Help

Nov 5, 2007

I'm using SQL Server Management Studio to do an extremely simple table update (I thought). I wish to fill a newly added table field with a value, however I didn't do this before... What I do is:


UPDATE _t_Computerhuys_MSCRM.dbo.ContactExtensionBase

SET New_Test = "Testvalue"


However then I get the errormessage:

Msg 207, Level 16, State 1, Line 2

Invalid column name 'Testvalue'.


Apparently what I see as a value is being looked at as a column name. I guess it has to do with syntax, but I can't find what's wrong. How to solve?

Insert Command

Nov 11, 2005

I have three tables t1, t2, t3. I want to insert a new row in t1. I am using access 2000 with sql commands for the queries. There are 4 colums in t1. I know the values of two of the colums. The remaining two columns values are going to be look up in the other 2 tables, 1 value from t2 table and the other value from t3.. I need this to be in one statement. From what I have seen you can either use insert with values() or you can populate your table with unkown values from another table. But I want to do both, since 2 of my values are known and the other 2 need to come from another table.

I hope that I made it clear enough. Can anyone help me

Thanks

Sql Insert Command Help

May 16, 2007

i am completely new to sql commands so i really need the help on this one.



I have three tables and they go like this



--User Table

firstTable->integerID

firstTable->stringName



--Group Table

secondTable->integerID

secondTable->stringName



--User to Groups table

thirdTable->integerFirstID

thirdTable->integerSecondID

thirdTable->stringDescription



the first table is has a user id and name and the second table has a group id and name, the third table keeps track of how many groups the user is assigned to. The problem i am having is writing a sql insert into command to add more entries to the third table from an asp.net 2.0 page, my sql command is incorrect.



The problem i am having i think, is that i am populating a dropdownlist with the names of all of the groups and when i select one that should be the group i am assigning to the user, the problem is, is that i dont know how to associated that dropdownlist string's name with its ID so that it can be passed to my insert command. is there a way to accomplish this all as a sql command? because i have a formview with a multiview and then a gridview under nested under all of that, and it would be a pain to write a event to work with all of the that.



if i do this it works

INSERT INTO ThirdTable (UserID,GroupID,Description) VALUES '318', '2', 'some description')

Question Regarding Using The Sql Update Command.

Jul 10, 2007

Here I have the following command
Dim dtNow As DateTime = DateTime.NowSqlDataSource1.UpdateCommand="Update [db] Set [LW]='TRUE', LWD=dtnow Where [PK]=@PK"What I was ttrying to accomplish was , in my grid view, when someone clicks update, it would automatically set LW to true and set LWD to today's date. No user intervention required. However, I figured the above script would not work. What would I have to do to make LWD = dtnow? I do not want to give the user the option to update anything.

Help With Booleans With UPDATE Command.

Jul 26, 2007

Hello, I'm using a Gridview to display a list of servers.  Each server has a column in a table called "Enabled."  I want to create a button that is supposed to toggle the value called "Enabled."  I am able to make the button either to set Enabled to true or false, but I don't know how to make it toggle.  Here is the command:UpdateCommand="UPDATE [ServerStatus] SET [Enabled] = 1 WHERE [ServerName] = @ServerName" The button is a buttonfield in the gridview:<asp:ButtonField ButtonType="Button" CommandName="Update" HeaderText="Toggle" ShowHeader="True" Text="Toggle" /> Does anyone know the syntax, or a way to make the button set Enabled to true when it is false, and false when it is set to true?
