Conditional Joins是一种SQL技术,用于在查询数据时优化性能并减少无效连接的数量。在复杂的查询中,连接操作是关键步骤之一,它允许我们将多个表中的数据关联起来。 在传统的JOIN操作中,两个表之间的连接是基于两个表之间的相等条件(例如使用等于符号)来进行的。但是,有时我们只需要在特定条件下才连接两个...
Even if you did manage to come up with a creative new syntax for doing "CASE JOINS" in SQL, it would not compile or execute in SQL since it is invalid. It's also the wrong approach. Instead, you simply LEFT OUTER JOIN tobothtables, and in your SELECT clause, return data from the ...

Someone mentioned using joins to table variables as an alternative approach. We've gotten excellent results using that technique where we could declare that all parameters of the search must have some value(s). Our procs accept lists of pipe(|) delimited strings which are parsed and used to ...
