Find Method Example (VB)

This example uses the Recordset object's Find method to locate and count the number of business titles in the Pubs database. The example assumes the underlying provider does not support similar functionality.

'BeginFindVB

    'replace the data source and initial catalog values
    'in the connection string

Public Sub Main()
    On Error GoTo ErrorHandler

     ' connection and recordset variables

    Dim rstTitles As New ADODB.Recordset

    Dim strSQLTitles As String
    
     ' record variables

    Dim count As Integer
    
     ' open connection
    Set Cnxn = New ADODB.Connection
    strCnxn = "Provider='sqloledb';Data Source='MySqlServer';" & _
        "Initial Catalog='Pubs';Integrated Security='SSPI';"
    Cnxn.Open strCnxn
       
    ' open recordset with default parameters which are
    ' sufficient to search forward through a Recordset
    Set rstTitles = New ADODB.Recordset
    strSQLTitles = "SELECT title_id FROM titles"
    rstTitles.Open strSQLTitles, Cnxn, adOpenStatic, adLockReadOnly, adCmdText

    count = 0
    rstTitles.Find "title_id LIKE 'BU%'"

        'continue if last find succeeded
        Debug.Print "Title ID: "; rstTitles!title_id
        'count the last title found
