ADLA Error Previewing External Table to SQL Azure Table

    Question

  • I have a table in SQL Azure and I am trying to create an External Table In Azure Data Lake Analytics that points to it

    I created a credential and data source and I can confirm that they work because I can view other external tables. But when I try to preview this specific table I get the following errors:

    • Failed to connect to data source: 'MYDATASOURCE', with error(s): 'Incorrect syntax near the keyword 'SELECT'.
      Incorrect syntax near ')'.'
    • CQO: Internal Error - Optimizer internal error.  Assert: csExtRowsetInfoNew != nullptr in managed\scopecqo.cpp:2235

    Any idea what could be causing this issue? Is it related to the table schema?

  • Hi, are you still running into this issue? If so, can you please share the Job ID to help us investigate.

    Also, can you explain what you mean by "previewing this specific table"? Are you running a SELECT query on the table?
