In my previous post Working with databases (OleDb, MS Access 2007) code-wise (SELECT COMMAND)<\/a> I’ve made a small introduction regarding this matter, so I won’t bother doing the same here.<\/p>\n

In order to execute UPDATE, INSERT OR DELETE statements against our database, we pretty much need the same objects as we did for retrieving data from a database:<\/p>\n

    \n
  1. A database connection\n
  2. A SQL command\n<\/ol>\n

    We’ll start off again by declaring the objects we need:<\/p>\n

    <\/p>\n

    'Declaring required objects\r\nDim oCon As New OleDb.OleDbConnection(\"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=MyDatabase.accdb;Persist Security Info=False;\")\r\nDim oCommand As New OleDb.OleDbCommand(\"\", con)<\/pre>\n
    <\/p>\n
    The following code snippet will show how to execute one of the statements:<\/p>\n
    'Code example for executing an UPDATE statement against our database\r\nTry\r\n\t'Set the query\r\n\toCommand.CommandText = \"UPDATE MyTable SET MyField = 'MyNewValue' WHERE MyField = 'MyCurrentValue'\"\r\n\r\n\t'Open connection\r\n\toCon.Open()\r\n\r\n\t'Execute the command\r\n\toCommand.ExecuteNonQuery()\r\n\r\n\t'Close connection\r\n\toCon.Close()\r\n\r\nCatch ex As OleDb.OleDbException\r\n\t'Show oledb exception\r\n\tMessageBox.Show(ex.ToString)\r\nEnd Try\r\n<\/pre>\n
    Now this example showed how to do UPDATE commands, but in order to execute INSERT or DELETE statement it works the exact same way.
    \nJust replace the oCommand.CommandText = “…”<\/b> with the statement you wish to use \ud83d\ude42<\/p>\n
    Have fun!<\/p>\n","protected":false},"excerpt":{"rendered":"
