How to create a proper Nested select statement in mysql

I am getting the error message "subquery returns more than one row" with the code below? I am trying to select only those records from the table shosondemand who's id is in the tmp_shoe_id table.   Whats wrong with the code?
select distinct * from shosondemand where id = (select *  from tmp_shoe_id);

Hi Dan,

There are several ways to do this.  Most common is to use IN.

select distinct * from shosondemand where id IN (select id  from tmp_shoe_id);

Good Luck,

If you need to use the = (equal sign) you need to make sure the second query only returns a single value.
I like this, but admit it's equivalent to Dan's query.  The advantage is that it allows you to select fields from the tmp_shoe table if you like:

Select s.* from shosondemand s inner join tmp_shoe_id t on =
