VS 2010 Insert Records In One Table From Another Table With Sql Satement?
Mar 27, 2012
I do this in Oracle databases just in a snap, but now I have to do it in VB using ADODB and I don't know how to do it.
I have two Access 2007 tables. Table A contains: Col1 (text), Col2 (text), Col3(date), Col4(amount), Col5(text)
Table B contains Col1(date), Col2(amount) What I need to do is to insert into table B the records of table A (col4 summed) grouped by date of table A. The date is a variable contained in a text box so it cannot be hardcoded into the SQL statement.
I have a database with 3 tables: Student, Unavailability and Duty.The fields for Student are entered in a form I have. One of the fields in Unavailability is filled by a form, the other fields are an autonumber and a foreign key to the Student table.ow I want records in the Duty table to be created and automatically filled in depending on what the values of the fields are in the Student table.For example, If the Boarder field in the Student table is 'yes' then I want the Duty Number field in the Duty table to be '1', '3' and '4'. If it is 'no' then I want the value to be '2' and '5'. I recognize it will have to create several different records to incorporate the different duty numbers for each StudentID. Obviously this will require an if statement, however this is my first time implementing a database with my limited experience with programming and Visual Basic, so I don't know how to refer to the specific fields in a table and set the value of other fields depending on the data in other fields.
I have this piece of code wich works perfectly when inserting records into one table using records from another table. My question is that now i need to create another table by using records from 3 other tables (tables are related). Can i use aliases on the column names, like on Oracle SqlPlus? How will be the syntax of the 'INSERT INTO SQL statement?
Dim MyConn As ADODB.Connection Dim MyRecSet As ADODB.Recordset Dim tmpSQL As String MyConn = New ADODB.Connection
I am a asp.net convert to VB.net and very new to VB.net(visual studio) I am trying to insert some records int a table. It seems the same code in asp.net does not work in VB.net. Here is an example of what I am trying to do
Dim Conn as New SqlClient.SqlConnection Dim cmd as Ne SqlClient.SqlCommand Conn.ConnectionString = "Data Soure......yada yada yada..."
Relatively new to VB.NET coding. Am creating a pretty simple console application that needs to insert over 50,000 records into an Oracle table (OleDB connection). I tried 3 different methods so far: Individual INSERT, insert using a dataset, & using INSERT ALL (commit every 25 records due to # of columns). It seemed like most articles/posts I read recommended the dataset approach, but the INSERT ALL code was definitely the fastest by far.
I would like to insert records a user selects from a gridview using check box column here is my code which inserts the first record then on the second interation it gives the error."The variable name '@Customer' has already been declared. Variable names must be unique within a query batch or stored procedure." [code]
I am rather new to vb.net using SQL CE. This is using 3.5 framework. I am trying to use a button to insert records into a table in a SQL CE database. Rowsaffected returns a value of 1, but when I preview the data, the row is never inserted. The sql statement I am using uses hardcoded values only because I am trying to get this to initially work. Once I can get the insert statement to work, it will use variables based on user input.
Here is my code that I am using: Private Sub cmdInsert_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdInsert.Click Dim connstr As String Dim rowsaffected As Integer connstr = ("Data Source =" _ + (System.IO.Path.GetDirectoryName(System.Reflection .Assembly.GetExecutingAssembly.GetName.CodeBase) _ + ("jhepfner.sdf;"))) [Code] .....
The original database that I am using is c:jhepfner.sdf. When I run this, connstr shows: Data Source =Program Filesjhepfnerjhepfner.sdf; In server explorer, it shows the connection string as: Data Source=C:Documents and SettingsCompaq_OwnerLocal SettingsApplication DataTemporary Projectsjhepfnerjhepfner.sdf
I'm using Visual Basic 2010 Express and Access 2003. I'm trying to make sql querys to the mdb file. I'm using OLEDBConnection. The Select query works fine, but I can't insert rows in the table. Here is the code.
Dim connStr As String = "provider=Microsoft.Jet.OLEDB.4.0;data source=" & System.IO.Directory.GetCurrentDirectory() & " pv.mdb;" Dim con As New OleDb.OleDbConnection(connStr) con.Open()
i have the following function to update my database:
Public Function Alterar(ByVal registro As Bancos) As Boolean Dim Key As EntityKey Dim OriginalEntity As Object = ""
[code]....

adding the records to Access table which has been entered in the form in vs2010.

I've found a sql string like: "SELECT Count(*) FROM table"My question is: how can I use this string and get the result into a variable in VB2010? I used to program with VB6 for years, but now things are very different.
In an application i am developing, I have to put an entire table in a cell of different table using vb.net . The process of creating a table is completely automated as per the input.
and what I'd like to do is when users edit something on this form that they post the changes to a table called exceptionsedit which is not part of that dataset. What I don't know how to do is to how to insert those edits to the exceptionsedit table.
I'm trying to insert a row into a SQL Server table.
Using this... cmd.CommandText = "INSERT INTO MyTable (firstname, lastname) VALUES (@firstname, @lastname)" cmd.Parameters.AddWithValue("@firstname", "bob") cmd.Parameters.AddWithValue("@lastname", "jones") cmd.ExecuteNonQuery()
I get an error saying: ERROR [42000] [Microsoft][ODBC SQL Server Driver][SQL Server]Must declare the scalar variable "@firstname".
But if I use this... cmd.CommandText = "INSERT INTO MyTable (firstname, lastname) VALUES (?, ?)" cmd.Parameters.AddWithValue("@firstname", "bob") cmd.Parameters.AddWithValue("@lastname", "jones") cmd.ExecuteNonQuery() ...it works fine. What do I need to do to make the first example work? I don't understand what the error message is telling me. How do I declare a "scalar variable"?
I need to split a string into parts to insert into a table (Data Grid View).
The string is as follows map: mp_shipment num score ping guid name lastmsg address qport rate --- ----- ---- -------------------------------- --------------- ------- --------------------- ----- ----- 0 0 7 719f826a9a7ee795ed3c43********** Not Yourself^7 0 127.0.0.1:28961 30793 25000
As you can see its for a game (Cod4) I am making a rcon tool. It is all going well apart from splitting the string. What I need is putting the (num, GUID, Name and address) for each person (I am showing only one) into a DGV.

I have a data table whose one column is related to a column of another table. I have a listbox in a form which shows a column (which is sorted by another column value by ORDER clause) of the parent table and other columns are in textboxes. The child table is represented by a datagrid. When I add a new item in parent table and click save, the newly created item is listed at the bottom of the listbox violating my ORDER clause. When I wrote some codes to fill data again after updating, it shows an error message[code]...
