보통 Recordset을 이용할 때 반복문으로 값을 구해 웹페이지에 표시한다.
ADO 2.0에서 GetString을 사용하면 이런 작업없이 같은 결과를 조회할 수 있는데, 속도면에서는 빠르겠으나 테이블의 디테일한 스타일이라던가 소스의 명시화에서 현업에서 잘 쓸지는 의문이 든다.

이런 것이 있다는 것 정도만 알면 되겠지.

The GetString method returns the specified Recordset as a string. This method can be used to fill HTML tables in ASP files.

Syntax

Set str=objRecordset.GetString(format,n,coldel,rowdel,nullexpr)

ParameterDescription
formatOptional. A StringFormatEnumvalue that specifies the format when retrieving a Recordset as a string
n

Optional. The number of rows to be converted in the Recordset

coldelOptional. If format is set to adClipString it is a column delimiter. Otherwise it is the tab character
rowdelOptional. If format is set to adClipString it is a row delimiter. Otherwise it is the carriage return character
nullexprOptional. If format is set to adClipString it is an expression used instead of a null value. Otherwise it is an empty string

Example

To create an HTML table with data from a recordset, we only need to use three of the parameters above:

  • coldel - the HTML to use as a column-separator
  • rowdel - the HTML to use as a row-separator
  • NullExpr - the HTML to use if a column is NULL

Note: The GetString() method is an ADO 2.0 feature. You can download ADO 2.0 at http://www.microsoft.com/data/download.htm.

Example

In the following example we will use the GetString() method to hold the recordset as a string:

<html>
<body>

<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open "c:/webdata/northwind.mdb"

set rs = Server.CreateObject("ADODB.recordset")
rs.Open "SELECT Companyname, Contactname FROM Customers", conn

str=rs.GetString(,,"</td><td>","</td></tr><tr><td>","&nbsp;")
%>

<table border="1" width="100%">
  <tr>
    <td><%Response.Write(str)%></td>
  </tr>
</table>

<%
rs.close
conn.close
set rs = Nothing
set conn = Nothing
%>

</body>
</html>
