sqlexception

I have some curious behavior that I'm having trouble figuring out why is occurring. I'm seeing intermittent timeout exceptions. I'm pretty sure it's related to volume because it's not reproducible in our development environment. As a bandaid solution, I tried upping the sql command timeout to sixty seconds, but as I've found, this doesn't seem to help. Here's the strange part, when I check my logs on the process that is failing, here are the start and end times: 09/16/2008 16:21:49 09/16/2008 16:22:19 So how could it be that it's timing out in thirty seconds when I've set the command timeout

I've got a strange problem. I have a .NET program and my process logic needs a long-running transaction (~20min) on a SQL Server 2005 database. That's ok, since nobody accesses the database in parallel. When something goes wrong, the transaction should be rolled back. Infrequently and without any visible pattern the Rollback() operation on my DbTransaction object throws a SqlException : Message: "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding." StackTrace: at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException

I'm writing generic logger for SQLException and I'd like to get parameters that were passed into PreparedStatement, how to do it ? I was able to get the count of them. ParameterMetaData metaData = query.getParameterMetaData(); parameterCount = metaData.getParameterCount(); Short answer: You can't. Long answer: All JDBC drivers will keep the parameter values somewhere but there is no standard way to get them. If you want to print them for debugging or similar purposes, you have several options: Create a pass-through JDBC driver (use p6spy or log4jdbc as a basis) which keeps copies of the

How can I get error text in MySQL 5.5 stored procedure when SQLEXCEPTION occurs? I need something along these lines to see what went wrong: DECLARE EXIT HANDLER FOR SQLEXCEPTION BEGIN GET DIAGNOSTICS CONDITION 1 SELECT "Table @p5 (Msg State @p2): @p1" END; Similar to Getting SQLEXCEPTION message in MySQL procedures , but there the Version was 5.6.4 - so GET DIAGNOSTICS was available. Pred As I know, there is no way to emulate or replace the functionality of GET DIAGNOSTICS in lower versions of MySQL (lower than 5.6.4). There are many entries on bugs.mysql.com and on MySQL forums which asks

I want to have @messages return @folder.messages where the value of column "deleted" is NOT equal to true. I'm not sure why this keeps throwing a SQLException. I guess I'm not formatting the deleted attribute properly, but I'm not sure how to fix it. Any help would be greatly appreciated. Thanks in advance.
