Join one row to multiple rows in another table

Use:

   SELECT x.name,          GROUP_CONCAT(y.property SEPARATOR ', ')     FROM PEOPLE xLEFT JOIN PROPERTIES y ON y.name = x.name    WHERE x.age > 26 GROUP BY x.name

You want the MySQL function GROUP_CONCAT (documentation) in order to return a comma separated list of the PROPERTIES.property value.

I used a LEFT JOIN rather than a JOIN in order to include PEOPLE records that don't have a value in the PROPERTIES table - if you only want a list of people with values in the PROPERTIES table, use:

   SELECT x.name,          GROUP_CONCAT(y.property SEPARATOR ', ')     FROM PEOPLE x     JOIN PROPERTIES y ON y.name = x.name    WHERE x.age > 26 GROUP BY x.name

I realize this is an example, but using a name is a poor choice for referencial integrity when you consider how many "John Smith"s there are. Assigning a user_id, being a unique value per user, would be a better choice.

You can use INNER JOIN to link the two tables together. More info on JOINs.

SELECT *FROM People PINNER JOIN Properties Pr  ON Pr.Name = P.NameWHERE P.Name = 'Joe' -- or a specific age, etc

However, it's often a lot faster to add a unique primary key to tables like these, and to create an index to increase speed.

Say the table People has a field id
And the table Properties has a field peopleId to link them together

Then the query would then look something like this:

SELECT *FROM People PINNER JOIN Properties Pr  ON Pr.id = P.peopleIdWHERE P.Name = 'Joe'

SELECT x.name,(select GROUP_CONCAT(y.Properties SEPARATOR ', ')FROM PROPERTIES y WHERE y.name.=x.name ) as Properties FROM mst_People x
