Using Parameters Inserting Data into Access Database

Using parameters inserting data into access database

Same as for any other query:

a) Replace actual hardcoded parameters in your OleDbCommand with placeholders (prefixed with @),

b) Add instances of OleDbParameter to the DbCommand.Parameters property. Parameter names must match placeholder names.

[WebMethod]
public void bookRatedAdd(string title, int rating, string review, string ISBN, string userName)
{
   using (OleDbConnection conn = new OleDbConnection(
         "Provider=Microsoft.Jet.OleDb.4.0;"+
         "Data Source="+Server.MapPath("App_Data\\BookRateInitial.mdb"));
   {

      conn.Open();

      // DbCommand also implements IDisposable
      using (OleDbCommand cmd = conn.CreateCommand())
      {
           // create command with placeholders
           cmd.CommandText = 
              "INSERT INTO bookRated "+
              "([title], [rating],  [review], [frnISBN], [frnUserName]) "+
              "VALUES(@title, @rating, @review, @isbn, @username)";

           // add named parameters
           cmd.Parameters.AddRange(new OleDbParameter[]
           {
               new OleDbParameter("@title", title),
               new OleDbParameter("@rating", rating),
               ...
           });

           // execute
           cmd.ExecuteNonQuery();
      }
   }
}

Inserting data into a access database using parameters

The connection was created but never set on the command object. BTW SqlCommand is a SQL Server Client command.

Instead of :

var cmd = new SqlCommand("INSERT INTO SUMMARY (A, B, C) VALUES (@A, @B, @C)");

Use

var cmd = new OleDbCommand("INSERT INTO SUMMARY (A, B, C) VALUES (?, ?, ?)",connection);

Access doesn't support named parameters in SQL queries. The parameter values will be substitued by position.

how to using INSERT INTO in c# for access database

2 things:

Use Parameters

When field name contains spaces use brackets

  OleDbCommand cmd = new OleDbCommand("INSERT INTO Members(name,family,age,[Juncture scholarships]) values(@name,@family,@age,@Js)",con);
    cmd.Parameters.AddWithValue("@name",t1.Text);
    cmd.Parameters.AddWithValue("@family",t2.Text);
    ...
    cmd.ExecuteNonQuery();
     ...

Unable to insert data in MS Access using parameterized query in c#

When i had the similar problems, solution was:

If database is part of application it can be copied in a bin folder - and then application work with it. That is why you can`t find your changes in datatables with MS Access client.

Inserting Bulk data into Access Database using DAO using C#

I expect the error is due to not referencing the recordset object.

Not sure the recFields array is needed. If the recordset pulls fields in the order you want to enter data, just reference the fields by index.

rs(k) = recList[k].Test1; or rs.Fields(k) = recList[k].Test1;

Or if recFields array actually has field names and you want to reference fields explicitly:

rs(recFields[k]) = recList[k].Test1;

Inserting data into database with autonumber in VB.net

You need to change your sql to "Insert into Table1 (OrderNo,Product,Qty,TDate) Values(@OrderNo, @Product, @Qty, @TDate)".

The following code works for me.

    DataGridView1.AllowUserToAddRows = False
    For Each row As DataGridViewRow In DataGridView1.Rows
        Dim connString As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=...;"
        Using conn As New OleDbConnection(connString)
            Using cmd As New OleDbCommand("Insert into Table1 (OrderNo,Product,Qty,TDate) Values(@OrderNo, @Product, @Qty, @TDate)", conn)
                cmd.Parameters.AddWithValue("@OrderNo", TxtOrder.Text.ToString)
                cmd.Parameters.AddWithValue("@Product", row.Cells("Product").Value)
                cmd.Parameters.AddWithValue("@Qty", row.Cells("Qty").Value)
                cmd.Parameters.AddWithValue("@TDate", Date.Now.ToString("MM/dd/yyyy"))

                If conn.State = ConnectionState.Open Then
                    conn.Close()
                End If

                conn.Open()
                cmd.ExecuteNonQuery()
                conn.Close()
            End Using
        End Using
    Next

Use Python to insert data into a MS Access Database

Python's Database API Specification lists several ways of doing parametrization:

• qmark: Question mark style, e.g. ...WHERE name=?
• numeric: Numeric, positional style, e.g. ...WHERE name=:1
• named: Named style, e.g. ...WHERE name=:name
• format: ANSI C printf format codes, e.g. ...WHERE name=%s
• pyformat: Python extended format codes, e.g. ...WHERE name=%(name)s

Most implementations only support one or maybe two. It looks like pyodbc uses qmark-style parameters, not format-style.

Try this instead:

cursor.execute("INSERT INTO ABCD (Serial) VALUES (?)", (k,))
