Description
Using invalid tokens (e.g., identifiers) with more than 20000 characters lead to an Internal Server error instead of a proper error message.
Example
-- It is necessary to replace ... in the following line with ~20000 characters SELECT a...a;
Workaround
Use only valid tokens and identifiers.
Fix
Exasol throws the error Parser error: input buffer overflow, can't enlarge buffer because scanner uses REJECT.
