Question

I have a MySQL query that is trying to get all the Pages that contain Data like ‘word%’. I have a many-to-many table called Pages2Data. It seems that to do this, I need to have an inner join connecting the Pages to the Pages2Data table, and then another inner join connecting Pages2Data to Data.

The following did not work, because the nested SELECT clause can return more than one row. I’m not sure how to fix it though:

SELECT * FROM `Pages` 
   INNER JOIN `Pages2Data` ON 
      (`Pages2Data`.`DataID`=(SELECT `DataID` FROM `Data` WHERE `DataWord` LIKE 'word%'))
      AND `Pages`.`PageID`=`Pages2Data`.`PageID`;

Answer 1

SELECT * FROM `Pages`     
INNER JOIN `Pages2Data`
   ON `Pages`.`PageID`=`Pages2Data`.`PageID`
INNER JOIN `Data` ON `Data`.`DataID`= `Pages2Data`.`DataID`
WHERE `DataWord` LIKE 'word%';
