This prepares without error on version 3.31.0 so, as Simon says, you probably
just have a version of SQLite3 that does not do window functions (ie, prior to
3.25.0) in which ROW_NUMBER() would have been parsed as a function call, OVER
as a column alias name, and the "(" as a syntax error (only a "," the keyword
"FROM", or the end of statement ";" could validly appear after an expression in
the select list).
