In response to ADO Connection with Postgres  ("Michael Aldor" <MAldor@greenridge.ca>)
List pgsql-odbc
I noticed I spelled appendchunk wrong, I am now getting the following error:

Operation is not allowed in this context. errorNum= 3219

This error seems to be due to incompatibility with appendchunk and bytea
as the error gets returned with an incompatible field according to Microsoft
http://support.microsoft.com/default.aspx?scid=kb;en-us;113949

Is there any other Postgres datatype that can store blobs? Is there another driver I should use that allows
compatabilitybetween bytea and appendchunk. 

Thanks.

Michael

I have the ADO recordset open connection working, however the append chunk is not inserting anything into the bytea
field(image). I am getrting data into image_name and content_type. Any ideas on how to insert binary data to postgres? 

rs.Open "image_table",ConnectionString, 2, 2, 2
'After I run rs.open the following error check gives me the following error:
if err then
  response.write("<br><br>" & err.Description & " errorNum= " & Err.number)
end if
'Object required errorNum= 424
 rs.AddNew
  rs("image_name") = nameRef
  rs("image").appenchunk fileData
  rs("content_type") = contentType
 rs.Update
rs.Close
Set rs = Nothing
' after code is run the data in nameRef and contentType are store in the database, however fileData is not.

Hello,

I am trying to connect to a postgres database in ASP (vbscript) and insert a blob into a bytea field. However I cannot
createan open connection via the following method. 

Any help/suggestions would be appreciated.

ConnectionString = "Driver={PostgreSQL};Server=<servername>;Port=5432;Database=imagedb;UID=imageUser"

Set rs = Server.CreateObject("ADODB.Recordset")
rs.Open "image_table", connectionString, adOpenKeyset, adLockOptimistic, adCmdTable
'After I run rs.open the following error eheck gives me the following error:
if err then
  response.write("<br><br>" & err.Description & " errorNum= " & Err.number)
end if
'Arguments are of the wrong type, are out of acceptable range, or are
'in conflict with one another. errorNum= 3001
'not sure what to change there
rs.begintrans
rs.AddNew
 rs("img_name") = nameRef 'name of the file
 rs("img").AppendChunk fileData 'file data being some binary data
rs.Update
rs.committrans
rs.Close
Set rs = Nothing
