Background

The use of datatype keywords (e.g., DATE, TIMESTAMP) at invalid places leads to an internal server error instead of an appropriate error message in Exasol 6.1.0.

Example:

SELECT DATE FROM (
        Select current_date as "DATE" from dual
);
 SELECT TIMESTAMP FROM (
        SELECT CURRENT_DATE AS "TIMESTAMP"
);
SELECT BOOLEAN FROM (
        SELECT CURRENT_DATE AS "BOOLEAN"
);

Fix

Display of an appropriate error message.

Example:

syntax error, unexpected DATE_
