Recordsets Collection

  • Article

A Recordsets collection contains all open Recordset objects in a Connection or Database object.

Remarks

When you use DAO objects, you manipulate data almost entirely using Recordset objects.

A new Recordset object is automatically added to the Recordsets collection when you open the Recordset object, and is automatically removed when you close it.

You can create as many Recordset object variables as needed. Different Recordset objects can access the same tables, queries, and fields without conflicting.

To refer to a Recordset object in a collection by its ordinal number or by its Name property setting, use any of the following syntax forms:

Recordsets(0)

Recordsets("name")

Recordsets![name]

You can open a Recordset object from the same data source or database more than once, creating duplicate names in the Recordsets collection. You should assign Recordset objects to object variables and refer to them by variable name.

Example

This example demonstrates Recordset objects and the Recordsets collection by opening four different types of Recordsets, enumerating the Recordsets collection of the current Database, and enumerating the Properties collection of each Recordset.

Visual Basic for Applications 
  Sub RecordsetX()

Dim dbsNorthwind As Database
Dim rstTable As Recordset
Dim rstDynaset As Recordset
Dim rstSnapshot As Recordset
Dim rstForwardOnly As Recordset
Dim rstLoop As Recordset
Dim prpLoop As Property


Set dbsNorthwind = OpenDatabase("Northwind.mdb")


With dbsNorthwind


  ' Open one of each type of Recordset object.
  Set rstTable = .OpenRecordset("Categories", _
     dbOpenTable)
  Set rstDynaset = .OpenRecordset("Employees", _
     dbOpenDynaset)
  Set rstSnapshot = .OpenRecordset("Shippers", _
     dbOpenSnapshot)
  Set rstForwardOnly = .OpenRecordset _ 
     ("Employees", dbOpenForwardOnly)

  Debug.Print "Recordsets in Recordsets " & _
     "collection of dbsNorthwind"

  ' Enumerate Recordsets collection.
  For Each rstLoop In .Recordsets

     With rstLoop
        Debug.Print "  " & .Name

        ' Enumerate Properties collection of each
        ' Recordset object. Trap for any 
        ' properties whose values are invalid in 
        ' this context.
        For Each prpLoop In .Properties
           On Error Resume Next
           If prpLoop <> "" Then Debug.Print _
              "    " & prpLoop.Name & _
              " = " & prpLoop
           On Error GoTo 0
        Next prpLoop

     End With

  Next rstLoop

  rstTable.Close
  rstDynaset.Close
  rstSnapshot.Close
  rstForwardOnly.Close

  .Close
