Doubling Quotes in SQL Server

This routine parses a string and returns an equivalent string where all the instances of a given substring are doubled. This is especially useful for doubling quotes within SQL statements to be passed to Access or other database engines that expect double quote marks to represent a single quote mark:
 
Public Function DoubleString (_
	ByVal str As String, _
	ByVal strDoubleString As String) As String

	Dim intStringLength As Integer
	Dim intDoubleStringLength As Integer
	Dim intPosition As Integer
	Dim strTemp As String
	intStringLength = Len(str)
	intDoubleStringLength = _
		Len(strDoubleString)

	strTemp = str

	If intStringLength >= _
		intDoubleStringLength And _
		intDoubleStringLength > 0 Then
		intPosition = 1

		Do While (intPosition > 0) And _
			(intPosition <= intStringLength)
			intPosition = InStr(intPosition, _
				strTemp, strDoubleString)
			If intPosition > 0 Then
				strTemp = Left(strTemp, _
					intPosition - 1 + _
					intDoubleStringLength) & _
					strDoubleString & _
					Mid(strTemp, intPosition + _
					intDoubleStringLength, _
					intStringLength)
				intStringLength = Len(strTemp)
				intPosition = intPosition + _
					(intDoubleStringLength * 2)
			End If
		Loop
	End If

	DoubleString = strTemp

End Function
