  • There are two reasons I have encountered for implicit joins. Some systems don't support the synrax. SQL::Statement is the one I have encountered.

    Also, some databases don't optimize as well with explicit joins. Until recently, PostgreSQL would not reorder joins and this limited how well the optimizer worked. The most recent version of PostgreSQL fixed this problem. But OUTER JOINs can't be reordered without potentially changing the results.

    I much prefer explicit joins. I think they the queries much clearer about what is going on.
