Dim cnnGetRows ' ADO connection Dim rstGetRows ' ADO recordset Dim strDBPath ' Path to our Access DB (*.mdb) file Dim arrDBData ' Array that we dump all the data into ' Temp vars to speed up looping over the array Dim I, J Dim iRecFirst, iRecLast Dim iFieldFirst, iFieldLast ' MapPath to our mdb file's physical path. strDBPath = Server.MapPath("db_scratch.mdb") ' Create a Connection using OLE DB Set cnnGetRows = Server.CreateObject("ADODB.Connection") ' This line is for the Access sample database: 'cnnGetRows.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strDBPath & ";" ' We're actually using SQL Server so we use this line instead. ' Comment this line out and uncomment the Access one above to ' play with the script on your own server. cnnGetRows.Open "Provider=SQLOLEDB;Data Source=;" _ & "Initial Catalog=samples;User Id=samples;Password=password;" _ & "Connect Timeout=15;Network Library=dbmssocn;" ' Execute a simple query using the connection object. ' Store the resulting recordset in our variable. Set rstGetRows = cnnGetRows.Execute("SELECT * FROM scratch") ' Now this is where it gets interesting... Normally we'd do ' a loop of some sort until we ran into the last record in ' in the recordset. This time we're going to get all the data ' in one fell swoop and dump it into an array so we can ' disconnect from the DB as quickly as possible. arrDBData = rstGetRows.GetRows() ' Some notes about .GetRows: ' The Method actually takes up to 3 optional arguments: ' 1. Rows - A long integer indicating the number of rows to ' retreive from the data source and put into the ' array. Defaults to adGetRowsRest which ' retreives all the remaining rows. ' 2. Start - An ADO bookmark indicating which row we should ' begin from. It can also be one of the following ' three ADO constants: adBookmarkCurrent, ' adBookmarkFirst, adBookmarkLast. Defaults to ' the current row, so if you've been moving around ' the RS it'll pick up wherever you left off. ' 3. Fields - A single field name or number or an array of ' names or numbers indicating which fields to ' retreive and place into the array. Defaults to ' all the columns. ' ' So a example using all the attributes would look like this: ' 'arrDBData = rstGetRows.GetRows(2, adBookmarkCurrent, Array("id", "text_field")) ' ' Which would get 2 rows starting from the current record and ' only returning data from the the id and text_field fields. ' ' FYI: the above line uses an ADO constant from adovbs.inc ' which I haven't included in this script: ' Const adBookmarkCurrent = 0 ' Close our recordset and connection and dispose of the objects. ' Notice that I'm able to do this before we even worry about ' displaying any of the data! rstGetRows.Close Set rstGetRows = Nothing cnnGetRows.Close Set cnnGetRows = Nothing ' ADO sets up the array so that the elements of the first ' dimension correspond to the DB fields and the elements of ' the second dimension correspond to the records. It might ' seem a little backward, but when you think about it, it ' makes sense because it's easy to modify the last dimension ' (to hold fewer or more records as needed), but modifying the ' first dimension is difficult so we use it to handle the ' fields which most likely wouldn't need to be modified. ' Here I get the upper and lower bounds of the field list ' and the records. This gives me some information about the ' data before I start and also allows me to not have to query ' the array for its bounds on each loop. iRecFirst = LBound(arrDBData, 2) iRecLast = UBound(arrDBData, 2) iFieldFirst = LBound(arrDBData, 1) iFieldLast = UBound(arrDBData, 1) ' Display a table of the data in the array. ' We loop through the array displaying the values. %> <% ' Loop through the records (second dimension of the array) For I = iRecFirst To iRecLast ' A table row for each record Response.Write "" & vbCrLf ' Loop through the fields (first dimension of the array) For J = iFieldFirst To iFieldLast ' A table cell for each field Response.Write vbTab & "" & vbCrLf Next ' J Response.Write "" & vbCrLf Next ' I %>
