I have this table, it only has one record in it and I want the string in the record to be put in a string name tbString. gromit 12-05-2005, 12:34 PM Hi - (and welcome!) The most simple way is to use the DLOOKUP function. E.g. tbString = DLOOKUP ("[Field]", "tblData", "[Field] = <some match criteria>") Note: if you are matching a string criteria then you have to put extra quotes around the criteria so that Access recognizes it as a string. E.g. tbString = DLOOKUP ("[Field]", "tblData", "[Field] = ""This String""") The other approach is to declare a recordset and query the database using a SQL statement. Unless speed is a crucial element, use DLOOKUP for ease. hth, - g uk_boy 12-05-2005, 11:16 PM Is it possible to use dlookup to change the record in the table? gromit 12-05-2005, 11:25 PM No, you will need to use SQL to do that. uk_boy 12-06-2005, 08:41 AM So how can I use SQL to do that??? gromit 12-06-2005, 10:30 AM Here is some example code that steps through each (existing) record in a table. The table has at least two fields: Name (text) and Number (number). ' Declare variables Dim db As DAO.Database Dim rs As DAO.Recordset Dim strSQL As String Dim intCounter As Integer intCounter = 1 ' Establish connection to database Set db = DBEngine(0)(0) ' Open a record set Set rs = db.OpenRecordset("tblData", dbOpenTable) ' Loop through records While Not rs.EOF rs.Edit ' Edit the record ' Insert some information rs!Name = "Name " & intCounter rs!Number = intCounter rs.Update rs.MoveNext ' Increment Counter intCounter = intCounter + 1 Wend ' Clean up and close rs.Close Set rs = Nothing db.Close Set db = Nothing hth, - g uk_boy 12-06-2005, 11:15 PM I tried running the code but for some reason it brings up an error in the dim section, its says that 'User-defined type not defined'. What should I do? I am currently running Access 2000 Bat17 12-07-2005, 12:30 AM in any module goto Tools>References...
