Using subselect to accomplish LEFT JOIN

multiple-columns, sql, subquery

Solution

A subselect can only have one column returned from it, so you would need one subselect for each column that you would want returned from the model table.

Problem

Is is possible to accomplish the equivalent of a LEFT JOIN with subselect where multiple columns are required. Here's what I mean. ``` SELECT m.*, (SELECT * FROM model WHERE id = m.id LIMIT 1) AS models FROM make m ``` As it stands now doing this gives me a 'Operand should contain 1 column(s)' error. Yes I know this is possible with LEFT JOIN, but I was told it was possible with subselect to I'm curious as to how it's done.
