Question

我尝试从Oracle 10g数据库加载blob图像。我在.ASP VB和.PHP中都试过了。

 TABLE = STD_IMAGE
 Name                            Null?    Type
 ------------------------------- -------- ----
 IMG_ID_NO                       NOT NULL NUMBER(10)
 IMG_IMAGE                       NOT NULL BLOB

ASP代码

 <%@ LANGUAGE="VBSCRIPT" %>
 <%Option Explicit
 Dim Rs, sSQL, OBJdbConnection
 ' Clear out the existing HTTP header information
 Response.Expires = 0
 Response.Buffer = TRUE
 Response.Clear
 'Change the HTTP header to reflect that an image is being passed.
 Response.ContentType = "image/jpg"
 Set OBJdbConnection = Server.CreateObject("ADODB.Connection")
 OBJdbConnection.Open "Provider=OraOLEDB.Oracle;Data Source=xxxxxx;User Id=xxxx;Password=xxxxx;"
 DIM itemID
 itemID = request.querystring("InventoryItemId")
 itemID = 25
 sSQL = "Select * from std_image where IMG_ID_NO=25"
 set rs = OBJdbConnection.Execute(sSql)
 If not rs.eof Then
 Response.BinaryWrite rs("IMG_IMAGE")
 Response.End
 End If
 CloseRecordset(rs)%>
 <%Set OBJDbConnection = nothing%>

PHP代码

 <?php   
 $db ="(DESCRIPTION =
 (ADDRESS =
     (PROTOCOL = TCP)
     (HOST = xxxxxx)
     (PORT = 1522)
  )
   (CONNECT_DATA = (SID = xxxxx))
   )";

$odbc = ocilogon ('xxxxxx', 'xxxxxx', $db) or die( "Could not connect to Oracle database!") or die (ocierror());

$sql = "SELECT IMG_IMAGE FROM std_image WHERE IMG_ID_NO = 25";  
$stid = ociparse($odbc, $sql);

ociexecute($stid);
$row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS);
if (!$row) {
    header('Status: 404 Not Found');
} else {
    $img = $row['IMG_IMAGE']->load();
    header("Content-type: image/jpg");
    print $img;
}
    ?>

对于这两个示例，我都会收到以下消息：

 The image “http://localhost/test_ShowImage.asp” cannot be displayed because it contains errors.  
 The image “http://localhost/test_getImage.php” cannot be displayed because it contains errors.

我用你的代码作为我的基础，它起作用了。我虽然使用了PHP ADODB库。

include("settings.php"); //includes db connection

$docid = $_REQUEST['document_id'];

$sql = "SELECT DOCUMENT_FILE FROM ACCOUNTS_DOCUMENTS WHERE DOCUMENT_ID = ".$docid;
$rs = $db->Execute($sql);
header("Content-type: image/jpg");
print $rs->fields['DOCUMENT_FILE'];

在PHP或ASP中显示oracle blob图像
