I have a question about this fiddle:

<>https://dbfiddle.uk?rdbms=db2_11.1&fiddle=d21840bf2df6c905b2238624c9ddf090

I am trying to create the Explain tables in Db2, but the user that runs the fiddle does not have permission on the stored procedure that create the tables.

I think the platform should give execution permission to all:

    
    grant execute on procedure SYSPROC.SYSINSTALLOBJECTS to public
    
By granting this, the execution plans for Db2 can be analyzed.
