このエラーが発生します：
SQL構文にエラーがあります。1行目の''JOIN `shirts_link` ON` shirts_link`.`shirt_id` = `shirts`.`id` JOIN` shirt_sizes'の近くで使用する正しい構文については、MySQLサーバーのバージョンに対応するマニュアルを確認してください。
私は今30分近くそれをとかしていて、それを理解することができません。誰かが私にそれを指摘してもらえますか？これがコードです。
SELECT
`shirts`.`shirt_name`,
`shirts`.`men` AS `main_photo`,
GROUP_CONCAT ( `shirt_sizes`.`size_name` ) AS `sizes`
FROM
`shirts`
JOIN
`shirts_link` ON `shirts_link`.`shirt_id`=`shirts`.`id`
JOIN
`shirt_sizes` ON `shirt_sizes`.`id`=`shirts_link`.`size_id`
JOIN
`shirt_prices` ON `shirt_prices`.`id`=`shirts_link`.`price_id`
WHERE `men`!=''
GROUP BY
`shirt_prices`.`price_cat`
問題がこのスクリプトよりも深刻な場合に備えて、これが私が結び付けようとしている他のテーブルです。
