ORA-00907: Missing right parenthesis
What it means
The parser reached a point where it expected ")" and found something else. Usually the real problem is earlier: a syntax error inside the parentheses (bad datatype in CREATE TABLE, ORDER BY inside an IN subquery, missing comma, wrong keyword).
How to fix it
Look at the content of the parenthesised block, not only at the brackets. Common cases: ORDER BY in a subquery used with IN, constraint clause written in the wrong place, VARCHAR2 without length, unsupported syntax for your database version.
