Code That Made Me Cry, #CTMMC™

95% of all code makes me cry. The other 5% are white space.

NO_BACKSLASH_ESCAPES (SQL, #12 / 48)

-- save mode & disable backslashes
SET @old_sql_mode=@@sql_mode;
SET @@sql_mode=CONCAT_WS(',', @@sql_mode, 'NO_BACKSLASH_ESCAPES');

-- run the query
SELECT 'C:\\media\data\temp\';

-- enable backslashes
SET @@sql_mode=@old_sql_mode;        

Server settings that enable / disable escaping have lead to one gazillion SQL injection and syntax problems. When will we get rid of these useless settings? Example by outis on Stack Overflow
