Defining a Recordset

You can create an ADODB.Recordset object and specify the column information. You can then insert data into the Recordset object; the underlying rowset buffers the inserts.

The following code example shows how to define a Recordset by using the RDSServer.DataFactory object. This can also be done with the RDS.DataControl object.

Sub RsDefineShape()
	
	Dim vntRecordSape(3)
	Dim vntField1Shape(3)
	Dim vntField2Shape(3)
	Dim vntField3Shape(3)
	Dim vntField4Shape(3)

	' For each field, specify the name,
	' type, size, and nullability.

	vntField1Shape(0) = "Name"	' Column name.
	vntField1Shape(1) = CInt(129)	' Column type.
	vntField1Shape(2) = CInt(40)	' Column size.
	vntField1Shape(3) = False		' Nullable?

	vntField2Shape(0) = "Age"
	vntField2Shape (1) = CInt(3)
	vntField2Shape (2) = CInt(-1)
	vntField2Shape (3) = True

	vntField3Shape (0) = "DateOfBirth"
	vntField3Shape (1) = CInt(7)
	vntField3Shape (2) = CInt(-1)
	vntField3Shape (3) = True

	vntField4Shape (0) = "Balance"
	vntField4Shape (1) = CInt(6)
	vntField4Shape (2) = CInt(-1)
	vntField4Shape (3) = True

	' Put all fields into an array of arrays.
	vntRecordShape(0) = vntField1Shape
	vntRecordShape(1) = vntField2Shape
	vntRecordShape(2) = vntField3Shape
	vntRecordShape(3) = vntField4Shape

	' Use the RDSServer.DataFactory to create an empty
	' recordset. It takes an array of variants where
	' every element is itself another array of
	' variants, one for every column required in the
	' recordset.
	' The elements of the inner array are the column's
	' name, type, size and nullability.

	Dim NewRs 

	' You could just use the RDS.DataControl object
	' instead of the RDSServer.DataFactory object. In
	' that case, the following code would be Set NewRs
	' = ADC1.CreateRecordset(vntRecordShape)
	Set NewRS = ADF.CreateRecordset(vntRecordShape)

	Dim fields(3)
	fields(0) = vntField1Shape(0)
	fields(1) = vntField2Shape (0)
	fields(2) = vntField3Shape (0)
	fields(3) = vntField4Shape (0)

	' Populate the new recordset with data values.
	Dim fieldVals(3)

	' Use AddNew to add the records.
	fieldVals(0) = "Joe"
	fieldVals(1) = 5
	fieldVals(2) = CDate(#1/5/96#)
	fieldVals(3) = 123.456
	NewRS.AddNew fields, fieldVals

	fieldVals(0) = "Mary"
	fieldVals(1) = 6
	fieldVals(2) = CDate(#6/5/96#)
	fieldVals(3) = 31
	NewRS.AddNew fields, fieldVals

	fieldVals(0) = "Alex"
	fieldVals(1) = 13
	fieldVals(2) = CDate(#1/6/96#)
	fieldVals(3) = 34.0001
	NewRS.AddNew fields, fieldVals

	fieldVals(0) = "Susan"
	fieldVals(1) = 13
	fieldVals(2) = CDate(#8/6/96#)
	fieldVals(3) = 0.0
	NewRS.AddNew fields, fieldVals
	
	x.MoveFirst

	' Set the newly created and populated Recordset to 
	' the SourceRecordset property of the 
	' RDS.DataControl to bind to visual controls.
	Set ADC1.SourceRecordset = NewRS

End Sub
