Is there a way to get around this error.

"CQO: Internal Error - Optimizer internal error. Assert: a_drgcidChild->CLength() == UlSafeCLength(popMS->Pdrgcid()) in rlstreamset.cpp:499"

Facing this issue while loading data from partitioned U-SQL table.

@myData =
    SELECT *
    FROM dbo.MyTable;

  • Can you share with us an anonymised script or repro of the issue? Otherwise consider raising a help request via the portal. – wBob Jun 13 '17 at 12:14
  • I updated the question with the SELECT statement – Ahsan Abbas Jun 14 '17 at 07:48
  • Is there any other information that you think might be useful for this question? eg the `CREATE TABLE` script (anonymised if needs be), the number of records in each partition, some sample data maybe? – wBob Jun 14 '17 at 11:13

If you encounter any system error message (or something that says Internal Error), please open a support ticket with us and/or send me your job link (if it happens on the cluster) or a self-contained smallest repro (if it is happening with local run) to usql at microsoft dot com.

Thanks Michael
