This error comes up pretty often and can be caused by a lot of different things. Usually, this is a pretty easy one to solve. It’s mostly just a syntax error and you forgot part of your SQL statement. You need a select, a column, from clause, and optionally a where clause to limit your select statement. Make sure you have those parts and you should be able to fix this issue.
Oracle lists the below cause in their Oracle oerr utility notes:
“A required part of a clause or expression has been omitted. For example, a SELECT statement may have been entered without a list of columns or expressions or with an incomplete expression. This message is also issued in cases where a reserved word is misused, as in SELECT TABLE.”
For example:
select column1 from table1;
