Server ConnectivitySeptember 27, 2005254 0 0 0 One of the more visible changes we made in connectivity space for SQL Server 2005 was enhancing error messages reported to the user sql server error 229 the execute permission was denied on the object 'sp_sqlagent_update_agent_xps' in case of connection failures. I have seen several cases over the last sql server error log several months, and in this post I would like to list some of them with the root cause that caused sql server error 233 them. The cause may not be the only one triggering a particular error message, and there may be other error messages of interest. This is a semi-random selection from real cases I sql server error 53 investigated. Likely I will post another batch some time in the future, and I would be happy to see replies with additional errors, particularly if the root cause is unclear. The examples are from various client stacks – ODBC or OLEDB from SQL Native Client or from managed SqlClient. The exact formatting of the messages will depend on the application you use. Most of the examples

2k5, plus, if running SQL Server on XP/WIN2K3/VISTA behind firewall, such problem occurs sql server error codes more frequently and harder for customer to get clue of behind reason. I. Background of remote connectivity issue. The sql server tsql error handling reason we saw the issue comes out w/ SQL 2k5 instead of SQL 2k is because two breaking change in SQL 2k5 compared to SQL 2000. 1) Network Protocols Off by https://blogs.msdn.microsoft.com/sql_protocols/2005/09/27/sql-server-2005-connectivity-error-messages/ Default: In order to make system secure, we limit connectivity when a user install SQL 2k5, thereby reducing surface area for attack. By default, SQL server (SQLEXPR, SQLDEV and EVAL SKUs), on installation will listen only on Shared memory and local-only Named Pipe. TCP and remote Named Pipe will be off-by-default. VIA will also be off-by-default;SQL server (SQLENT, STANDARD and Workgroup SKUs), https://blogs.msdn.microsoft.com/sql_protocols/2006/09/30/sql-server-2005-remote-connectivity-issue-troubleshoot/ on installation will listen only on Shared memory, local-only Named Pipe and TCP. Remote Named Pipe will be off-by-default. VIA will also be off-by-default. Therefore, when you mae remote connection, you should make sure at least either Named Pipe or TCP are enabledin your remote SQL instance. 2) SQL Browser service: which is a replacement of SSRP system in SQL Server 2000, run as a Windows Service on installation of SQL 2k5. Upon startup, SQL Server Browser starts and claims UDP port 1434. When SQL Server 2000 and SQL Server 2005 clients request SQL Server resources, the client network library sends a UDP message to the server using port 1434. SQL Server Browser responds with the TCP/IP port or named pipe of the requested instance. Therefore, you need to make sure SQL Browser is enabled and started when remote client ask for which tcp port or pipe name SQL Server is listening on. If your remote SQL Instance is a default instance, you do not necessary enable sql browser since client would always try default TCP port 1433 and pipe name \

What is the best way to write SQL code so that I will never see this error message again? I could do either of the following: Add a where clause so that my divisor is never zero Or I could add a case statement, so that there is a special treatment for zero. Is the best way to use a NullIf clause? Is there better way, or how can this be enforced? sql sql-server sql-server-2005 sql-server-2008 share|improve this question edited Jan 6 at 19:50 Hooper 4191525 asked May 14 '09 at 6:06 Henrik Staun Poulsen 4,89331220 4 Perhaps some data validation is in order. –Anthony May 14 '09 at 19:17 add a comment| 15 Answers 15 active oldest votes up vote 350 down vote accepted In order to avoid a "Division by zero" error we have programmed it like this: Select Case when divisor=0 then null Else dividend / divisor End ,,, But here is a much nicer way of doing it: Select dividend / nullif(divisor, 0) ...
