+--------------------------------------+
| CONCAT(LOWER('Class'), UPPER('xii')) |
+--------------------------------------+
| classXII |
+--------------------------------------+
Working
In the query, LOWER('Class') converts 'Class' to lowercase, resulting in 'class', and UPPER('xii') converts 'xii' to uppercase, resulting in 'XII'. The CONCAT() function then combines these two results, producing the final output 'classXII'.
