SQL Job executing SSIS - Could not complete cursor operation because the table schema changed after the cursor was declared

I have been trying to get this issue resolved for a couple of days but none of the issues when searching on the web directly explains why I am getting this error as there is no cursor being executed on this package.

I have a SQL Job which executes a SSIS package - This package is pretty much explained here :

As the above shows, there are a number of schema changes that happens which could ultimately explain why I am getting this error but this error never seems to occur when the packages is executed manually and only through the SQL Job. It also seems to happen spontaneously, one day it works, then next it give me this error :

The above error does mention Load into Stageing Database - the following is contained within that Data Flow Task:

Can someone explain this anomaly and is there a way around this?

Solution

  • Reading through the error I believe the key to answering your question isn't the cursor but rather these parts of the error:

    • The PrimeOutput method on component "Retrieve ITExtr03FinM" (1) returned error code 0xC02020C4
    • DTS_E_PRIMEOUTPUTFAILED
    • Load into Stageing Database Retrieve ITExtr03FinM 1 Description: The attempt to add a row to the Data Flow task buffer failed with error code 0xC0047020

    this discussion on SqlServerCentral suggests RAM/Memory Buffer configuration as an issue https://ask.sqlservercentral.com/questions/46865/ssis-data-flow-task-getting-error-code-0xc02020c4.html

    this link suggests a 32 vs 64 bit issue. Are you using 64 bit local and 32 bit on your server? SSIS ERROR: The attempt to add a row to the Data Flow task buffer failed with error code 0xC0047020

    I found a few more links that suggest RAM as an issue, which would make since why it would be an issue on one machine but not another because configurations would be different. Also if you run package during a heavy use time of the server less memory would be available for your operations.
