Syntax

  • INNER and OUTER are ignored.

  • FULL is not implemented in MySQL.

  • "commajoin" (FROM a,b WHERE a.x=b.y) is frowned on; use FROM a JOIN b ON a.x=b.y instead.

  • FROM a JOIN b ON a.x=b.y includes rows that match in both tables.

  • FROM a LEFT JOIN b ON a.x=b.y includes all rows from a, plus matching data from b, or NULLs if there is no matching row.
