Delving the depths of computing,
hoping not to get eaten by a wumpus

SQL::Functional Cookbook--Updates

2017-04-04


Updates are easy, too.

    my ($sql, @sql_params) = UPDATE 'foo', SET( 
            op( 'bar', '=', 1 ),
            op( 'baz', '=', 2 ),
        ),
        WHERE match( 'qux', '=', 3 );

UPDATE takes a table to update, followed by SET and WHERE. In SET, we’re using the op function, which is actually an alias for match. Calling it op is more readable here, since we’re not matching anything. Note that the data there is still handled as placeholders.

The WHERE part works just like it does in SELECT.
