Question 4 - Mar 09, 2011

What is the exact output of the following SQL:

SELECT CONCAT(CONCAT_WS('', REPLACE(REPLACE('MySQL is not fun', 'MySQL', 'CUBRID'), 'not', 'really'), '!') || CHR(32) || CONCAT_WS('-', CHR(72) || LOWER(CHR(65)), UPPER(CHR(104)) || CHR(97)), TRANSLATE(LTRIM('@#' || CHR(72) || LOWER(CHR(65)), '@'), '#', '-'));

Question 5 - Mar 14, 2011

Using the chars '1', '4', '5' and '6', obtain the number 29, following these rules:
