Re: PSQLODBC.DLL - The (maximum) expected data length is 8000, while the returned data length is 9606. - Mailing list pgsql-odbc

Thanks,

I've replaced the 'text' column.

Here is the error messages when I use 'varchar(max)':

Msg 7347, Level 16, State 1, Procedure RetrieveHttpEvents, Line 18
OLE DB provider 'MSDASQL' for linked server '(null)' returned data that does not match expected data length for column
'[MSDASQL].uri'.The (maximum) expected data length is 8000, while the returned data length is 9606. 

And here is the error messages when I use 'varchar(max)':

Msg 7347, Level 16, State 1, Procedure RetrieveHttpEvents, Line 18
OLE DB provider 'MSDASQL' for linked server '(null)' returned data that does not match expected data length for column
'[MSDASQL].uri'.The (maximum) expected data length is 8000, while the returned data length is 9606. 

So unfortunately this does not appear to have made a difference.

Here is my current query on SQL Server:

INSERT http_events
SELECT *
FROM openrowset
(
 'MSDASQL',
 'Dsn=PostgreSQL35W;',
 'Select
      event_id,
      time_stamp,
      session_id,
      client_intf,
      server_intf,
      c_client_addr,
      s_client_addr,
      c_server_addr,
      s_server_addr,
      c_client_port,
      s_client_port,
      c_server_port,
      s_server_port,
      policy_id,
      username,
      hostname,
      request_id,
      method,
      uri,
      host,
      c2s_content_length,
      s2c_content_length,
      s2c_content_type,
      adblocker_blocked,
      adblocker_cookie_ident,
      adblocker_action,
      webfilter_reason,
      webfilter_category,
      webfilter_blocked,
      webfilter_flagged,
      sitefilter_reason,
      sitefilter_category,
      sitefilter_blocked,
      sitefilter_flagged,
      clam_clean,
      clam_name,
      virusblocker_clean,
      virusblocker_name
 FROM reports.http_events AS log'
)

What additional information can I provide you that would be useful?

First, as I understand it text is deprecated in SQL Server:

https://msdn.microsoft.com/en-us/library/ms187993.aspx

The 8000 limit you are hitting is seems to the upper limit of SQL Server
varchar() unless you specify max:

https://msdn.microsoft.com/en-us/library/ms176089.aspx

So I wonder if somewhere along the line varchar(8000) is being substituted for text()?

This will need a more detailed description of what you are doing to answer.
