• Mysteries unraveled:
   
  • SUBSTRING_INDEX() parsing
     
  • JOIN as column-glue – what LEFT,
    RIGHT, INNER, OUTER, NATURAL,
    ON, and USING really mean
     
  • UNION as row-glue
     
  • GROUP_CONCAT()  2-dimensional
    string concatenation
     
  • Storage details: CHAR, BINARY,
    TEXT, BLOB, VARCHAR, and
    VARBINARY, plus the variations:
    TINY, MEDIUM, SMALL, LONG, BIG
    and what they really give you
     
  • back-tick `quotes` – when to use
     
  • NULL as a computational black hole
     
  • WEEK() and YEARWEEK()
    numbering schemes – calendar
    versatility
     
• MySQL in its natural habitat: PHP and
  command-line examples
   
• Operator precedence
   
• Regular expression parts, examples
   
• Date and time formatting codes,
  examples, and equivalent functions
   
• Column aliases – where they're
  welcome (GROUP BY, HAVING,
  ORDER BY) and where they can't
  be used (WHERE clause, column
  expressions)

Format dates and times fast with clues from the example columns.
See the difference between %d and %e?  Clear as day?

 
Here's some content you won't find anywhere else: what those wacky
week numbering schemes mean in practical terms. The manual sure
leaves you wondering what-were-they-thinking. Turns out, it's brilliant:
