ADO not receiving errors raised in sub procedure

Palloquin — Tue, 31 Aug 2010 11:42:26 +0000

Hi,

I’v known for a while that ado has it’s limits when it comes to dealing with errors… but this one hurts:

I have a StoredProcedure (SP) that calls a sub procedure.

In the sub procedure an error is raised.

The error does not reach ADO for some reason.

After some research I find that if the sub procedure returns a result set before it raises the error this problem occurs, else, the error reaches ADO just fine.

Example code:

main procedure:

CREATE PROCEDURE sp_test

EXEC sp_error

sub procedure:

CREATE PROCEDURE [dbo].[sp_error]

/* IF THIS LINE IS HERE, ERROR DO NOT SHOW UP IN ADO */

SELECT 'test' AS value

RAISERROR ('this is an error', 16, 1)

RETURN

VBSCript (ASP) code:

dim oConn, oRS

Set oConn = Server.CreateObject("ADODB.Connection")

oConn.ConnectionString = ConnString

oConn.CommandTimeout = 180

oConn.Open

Set oRS = Server.CreateObject("ADODB.recordset")

oRS.activeconnection = oConn

oRS.cursortype = 3

oRS.locktype = 4

oRS.CursorLocation = 3

oRS.source = "EXEC test.dbo.sp_error"

oRS.open

oRS.close

oConn.close

SET oRS = Nothing

SET oConn = Nothing

Now, I understand that I could work around this, by testing for the error in the main procedure etc… BUT THIS SHOULD JUST WORK!!!

Any thoughts?

ADO connection fails after upgrading from Oracle 10g to Oracle 11g

OracleATE — Tue, 03 Feb 2009 15:57:03 +0000

I have an Oracle 11g database and am using ADO to communicate with it. Under 10g the ADO Connection property ‘SERVER’ returned the correct database name, but since upgrading to 11g, the returned SERVER name is NULL. Any ideas?

Notes rich text field to BLOB/Memo field in SQL Server using ADOdb

tjarman — Sun, 01 Feb 2009 19:40:56 +0000

I have an agent that uses ADODB to connect and insert a row into a SQL Server database. I want to store the contents of the Body field in the memo (rich text) into a Memo field in the SQL Server database (or Blob field). I’m finding examples of reading this kind of data back into a Notes application but not an example of taking Rich Text data into the Memo/Blob field in the RDB using ADO. Any help would be greatly appreciated. The Body field is your typical Body field in a mail memo where it can have formatting, attachments, embedded objects, etc.

Writing vertical data to a flat (unfortunately!) table

Kingle1 — Fri, 12 Dec 2008 20:34:35 +0000

I have an application that I need to update (written by someone else) that requires that I take data from a nice, vertical table and write them into a pre-exisiting flat table. Column 1 of the vertical table is the PK for the flat table, while there are up to 35 entries that must be written into the flat table — each one would be a record in the vertical table. Any help would be greatly appreciated.
