Open
a new Standard EXE Visual Basic project. From the menu, select
"Project" and then "References." Click the check box next to "Microsoft
ActiveX Data Objects 2.x" where "x" is the highest number available on
your machine. Click the "OK" button to save and close.
Add
a new button to the default "Form1" that was created by default. Name
the button "cmdUpdate" and set the caption equal to "Update." This
button will save any updates directly to the appropriate table(s).
Declare variables to store the ADODB objects and a string variable for the SQL statement itself.
Dim oConn As ADODB.Connection
Dim strSQL As String
Dim oCmd as ADODB.Command
Dim oConn As ADODB.Connection
Dim strSQL As String
Dim oCmd as ADODB.Command
Connect to the database in the "Form_Load" event of "Form1."
Set oConn = New ADODB.Connection
oConn.ConnectionString = "DSN=MyDBName;Uid=admin;Pwd=password;"
oConn.Open
Set oConn = New ADODB.Connection
oConn.ConnectionString = "DSN=MyDBName;Uid=admin;Pwd=password;"
oConn.Open
Code the SQL for the "update" statement in the click event of "cmdUpdate."
strSQL = "UPDATE myTable SET columnName = 'NewName' WHERE ID = 3;"
oCmd.CommandText = strSQL
oCmd.Execute
strSQL = "UPDATE myTable SET columnName = 'NewName' WHERE ID = 3;"
oCmd.CommandText = strSQL
oCmd.Execute
