I'm a looking for a way for see a preview before execute a migration, something like debug an Active Record but into a migration.
// Example for debug sql for a Active record
echo $query->createCommand()->getRawSql();
My purpose is save time in the trial and error process.
I would like know if exists a way for debug sql query before run.
You cannot debug migration. Just run the migration and see what happens.

I am trying to implement logging in my SSIS package. I would like to start logging by writing a message- Batch started -- to my custom log table. I am currently having the following tasks created which run in parallel. I am thinking of creating a execute sql task which will log that. How do I tell SSIS to execute sql task before executing the other tasks in the package. Do I need to move all these tasks in a sequence container.
Please find the screenshot of my package.
The best way I feel to implement logging is to have it in a non-intrusive manner i.e. to have them run in the background. SSIS provides this facility via 'Event Handlers'.
Open your package and go to 'Event Handlers'. With 'Executable' set as "Your Package Name", select 'OnPreExecute' as 'Event handler'. You then click on the hyperlink for you to proceed with adding the 'Execute SQL Task' for auditing.
Using the same above, you can then go on to add 'OnPostExecute'. Additionally this technique can be implemented across individual task level as well.

I have an SSIS package which downloads data from AS400 to SQL Server.
This is working fine but:
The pre-final task (Execute SQL task) is to delete the downloaded records from AS400.
The query is simple:
DELETE FROM (TABLE_NAME)
I am pretty sure that this task is being hit because a Send Email task after this is working.
The issue is occurring on one server only. And I am unable to figure out why.
The entire setup is the same for all servers.
Try to track down the joblog of the job servicing the request. If there are errors that are being passed along by SSIS, you'll see them there.
One issue I've seen, especially with people that still call the system AS/400, is that the tables aren't being journaled; which means that when SSIS attempts to delete the rows under commitment control, it will fail with an error.
I have a simple package to produce a csv file from a query and update a 'lastrun' time on a table. This was written in 2014, running on a test server with 2014. The agent job that runs it simply executes it via an SSIS Package step. No other steps are involved.
However, I get the above error message in the agent log file. The job will successfully execute and produce a file, but ONLY after either restarting the agent service or changing the properties on the job (after refreshing the job list in SSMS). And because it seemingly deletes itself during execution, there is no job history to view, and then the schedule will stop repeating.
I can't find anything like this on here, and wondered if anyone has ever seen this, or has any ideas?
Thanks.
Note (update) : All other agent jobs run ok on the same server. The only difference with this one is that it's the only one that is calling an SSIS package.
It could be when you try to restore the same database (subscriber/distribution) as another database name, it will clear the job automatically.
I have a SSIS that has been working for over a year, and just in a couple of days I made a bunch of changes. When I try to deploy, it returns me an error saying
The current transaction cannot be committed and cannot support operations that write to the log file. Roll back the transaction.
It doesn't tell me what or which package is causing this issue.
Is there any way to trouble shoot this?
I appreciate any recommendation!!
In my case, the reason of the error was trigger on SSISDB DB for DDL_DATABASE_LEVEL_EVENTS, wich tried to write info in another DB.
I just solve it, the partitionw as running out of free space, I just cleaned the log, and it's back to normal!
I changed the name of my Solution and Project but wanted to deploy to the same location in the SSISDB Catalog. I was getting this specific error because of the name change (it was failing on deployment step when it called the internal.preparedeploy procedure). I ended up deleting the Project that existed on the Target Server and re-deploying the new Project to the same location. It deployed successfully.

I've been reading "SQL Server 2008 Integration Services Problem - Design - Solution". It outlines a way of logging variable changes which I'm trying to replicate in SQL 2005.
Create variables e.g. PackageId, RecordsAffected. - Set Raise ChangeEvent to true.
Create a string variable g.g. strVariableValue. - Set Raise ChangeEvent to false.
On the package event handler: OnVariableValueChanged add a script task "SCR Convert value to string".
Add ReadOnlyVariables: System::VariableValue
Add ReadWriteVariables: User::strVariableValue
In the script, set a local variable to System::VariableValue.value.tostring
Set the variable User::strVariableValue to the local variable
Add an "Execute SQL Task" component "SQL Log Variable Value Changed" calling a SP with no resultsets.
Set parameter mapping to User::PackageId, System::VariableName, User::strVariableValue
When this is run, I get a deadlock on User::PackageID
Error: 0xC001405B at SQL Log Variable Value Changed: A deadlock was detected while trying to lock variable "User::_PackageID" for read access. A lock could not be acquired after 16 attempts and timed out.
The script step succeeds but the Execute SQL task fails. I'm using Visual Studio 2005 Version 8.0.50727.42, Microsoft SQL Server Integration Services Designer Version 9.00.4035.00 and BIDSHelper Version 1.4.3.0.
Any ideas?
Eureka!
I had the same problem and led to a few deadend posts, then I discovered the root.
I had the framework working just fine and wanted to force some info to be logged.
So I changed the value of the framework variable "strVariableValue" and this caused the deadlock with the change event task.
I fixed by creating my own variable "strLogMe" and putting whatever I wanted to log.
Moral: don't touch the framework variables
Did you use the code sample from the book? All the files are available on the Wiley website for free. The code sample includes a SSIS package, sql scripts, and VB code for the script. If this doesn't work for you, then let me know since one of my team members found a way to log variable changes that was different from this methodology.
I was getting this error ("a deadlock was detected" etc), suddenly, which seemed to coincide with I.T. having done a Microsoft Windows patch on the server. There were packages which were using script tasks, with read-only and/or read-write variables in the SSIS UI. Even though it seemed to have been an environmental issue (because the packages had worked for months, then suddenly stopped working, even though I hadn't changed any code), I thought, well (as I had seen from various blog posts from years gone by), there were instances of companies doing server patches, then having their SSIS packages break; and the blogs seemed to say, change the way you're locking the variables, don't reference them in the UI; instead, lock them explicitly in code. So I tried the same thing. It didn't fix it.
It turns out some individual had removed the permissions of the user under whose identity the packages run, from the AD group; those permissions were required because it was trying to copy a file from a directory which required read permissions on the directory. These packages are typically called by a SQL agent job using a proxy identity. When the package was executed manually from SSMS, it worked. But when it was run by calling the SQL agent job, it failed.
The bottom line is, it was just coincidence that the packages started failing around the time of the Windows update. But the other (main) point is, if your package is trying to access a file on the network, and the identity (or proxy identity) under which that package runs does not have permissions to the source or target directory, then your package could fail and the problem could manifest itself in this cryptic way, where it looks like a variable deadlock issue, but it's actually a file share permissions issue. I only wasted a day on this, but... maybe this will be useful to somebody in the future.
