There are SQL comments above the SELECT statement within the Connect In-DB or Input Data tool query box.


There are other Data Manipulation Language (DML) statements other than the SELECT statement in the main SQL query field. (i.e. UPDATE, CREATE, etc.)


Remove all comments from the SQL query or ensure there are no extra spaces before the SELECT statement.

Specifically for the Input Data tool, if needing to put other DML statements such as an UPDATE statement, utilize the the Pre or Post SQL Statement fields in the properties section.
