delete_from hangs up

Posted on by dark_knight 768

Hello everyone,

I'm trying to delete multiple records at a time using delete_from sql command. It is said here

https://docs.microsoft.com/en-us/dynamicsax-2012/developer/delete-from

that if I have delete method overridden isystem interprets the delete_from statement into code that calls the delete method one time for each row that is deleted.

I don't have delete method overridden but this command hangs up. I also tried some other trick like

        mytable.skipDeleteActions(true);
        mytable.skipDeleteMethod(true);
        mytable.skipEvents(true);

        delete_from mytable
            where mytable.createdDateTime < utcCurrentStoringPeriod;

what can cause such behavior? Can you pls help me?

Thanks.

    Data is collected through ETW, Event Tracing for Windows, which a part of Windows operation system. Trace Parser itself is a separate application for analyzing these logs.

    Note that this is not your only option, you can also use things like SQL trace in AX and standard features of SQL Server (profiler, extended events etc.). If you want deal with performance problems, it's crucial to be able to measure both X++ code execution and database queries, therefore you must learn some of these tools.

    I used method skipDataBaseLog() on the table with no results. Is TraceParser some native utilities for ax?

    It's difficult to simply guess what's going on in your system. You should collect more information - consider using Trace Parser for that.

    For example, you may have a problem with an index, or there may be database log set up causing deletes execute row by row, or who knows...
