08V01/5181: Unexpected message type 0x43

Hello.

I'm using 7.2, an app works via ODBC interface. Sometimes (in a one from my use cases this is fairly reproducible) i see that inserted rows are lost!

I've caught an issue with inserts. In one transaction I'm doing couple of selects and couple of inserts. After that, I may find 2 rows in the table (test performed on an empty table), but may find only one! No errors is reported back via ODBC fuctions return codes.

Sequence from ODBC point view is standard - SQLPrepare, BindParameter, Execute. After SQLExecute i check result with SQLGetrowCount - it's always 1 and result is SQL_SUCCESS. But in query_requests i see status 'fail' and in vertica.log lines like following:

Table is simple, no keys or other constraints.

What's wrong? How to deal with such an error, which even is not reported with return codes???

 

Thanks in advance,

    Hi,

     

        Is autocommit on in your odbc client?

  • No, but you can see COMMIT record in log provided. Moreover, I'm able to see records - one or two - via another connection (i'm using DBVisualizer to interact with DB independently from application)

  • Hi ,

    Vertica normally translated insert statement into COPY commands :

     

    TX:a0000000045a1e(localhost.localdoma-15611:0x73880) insert into "OBJ43012588"(FIELD4, DIM, CL, CD) values (?, ?, ?, ?)
    2016-03-17 06:42:07.619 Init Session:0x7fe148011ea0-a0000000045a1e [Session] <INFO> [Query] TX:a0000000045a1e(localhost.localdoma-15611:0x73880) COPY xxx.OBJ43012588 ( FIELD4, DIM, CL, CD ) FROM LOCAL STDIN NATIVE VARCHAR ENFORCELENGTH RETURNREJECTED AUTO NO COMMIT

     

     

    Seems like something is wrong with this translation , COPY now include schema "XXX" , you probably hitting a bug .


    I hope you will find it useful
    Thanks

  • First of all, I've changed actual schema name to 'xxx' from privacy reason. I do not think that translation is the issue's cause since you may see two similar requests were translated and one of them was processed normally, second was failed. Moreover, as I' ve mentioned, sometimes both queries are passed successfully, but sometimes ( this log illustrates the case) - only one. And one more notice - error message seem to have internal exchange nature because tells about unrecognized message type....

    Hi,

     

    Any ideas/suggestions no how to bypass that issue?

     

    Thanks,

      Axel

    Hi,

     

          Please open a support ticket. It looks like it needs to be analyzed more

     

    Sruthi

  • Sorry, could you point me to the correct place to do that?

    Thanks,

      Axel
