The SQL statement below used to work a few years ago, now it doesn’t and I get this error message:

1054 – Unknown column ‘Promotion_Card_details.Card_id’ in ‘on clause’

This is my SQL statement:

SELECT DISTINCT Promotion_Card_details.Card_id, 
       Promotion_Merchant_details.Merchant_id, 
       Promotion_details.Promotion_id, 
       Issuer_details.IssuerName, 
       Card_details.CCType, 
       PaymentType_details.PaymentTypeName, 
       Merchant_details.MerchantName, 
       PromotionText, 
       PromotionEndDate 
FROM Promotion_details 
INNER JOIN Card_details ON (Card_details.Card_id=Promotion_Card_details.Card_id) 
INNER JOIN Issuer_details ON (Issuer_details.Issuer_id=Card_details.Issuer_id) 
INNER JOIN PaymentType_details ON (PaymentType_details.PaymentType_id=Card_details.PaymentType_id) 
INNER JOIN Merchant_details ON (Merchant_details.Merchant_id=Promotion_Merchant_details.Merchant_id) 
INNER JOIN Promotion_Merchant_details ON (Promotion_Merchant_details.Promotion_id=Promotion_details.Promotion_id) 
INNER JOIN Promotion_Card_details ON (Promotion_details.Promotion_id=Promotion_Card_details.Promotion_id) 
WHERE ((Promotion_details.Promotion_id = '13' OR Promotion_details.Promotion_id = '14'  
            OR 
      Promotion_details.Promotion_id = '15' OR Promotion_details.Promotion_id = '16' OR 
      Promotion_details.Promotion_id = '17' OR Promotion_details.Promotion_id = '18' OR 
      Promotion_details.Promotion_id = '19' OR Promotion_details.Promotion_id = '20' OR
      Promotion_details.Promotion_id = '21' OR Promotion_details.Promotion_id = '22' OR 
      Promotion_details.Promotion_id = '23' OR Promotion_details.Promotion_id = '24' OR 
      Promotion_details.Promotion_id = '25' OR Promotion_details.Promotion_id = '361' 
      OR Promotion_details.Promotion_id = '364' OR Promotion_details.Promotion_id = '382') )

Any help would be greatly appreciated as I have tried parentheses around certain parts, but it still hasn’t fixed it.

    JOINs are left-associative, so a given ON clause can only refer to tables that have already been mentioned. So, reorder these:

    FROM Promotion_details 
   INNER JOIN Card_details ON (Card_details.Card_id=Promotion_Card_details.Card_id) 
   INNER JOIN Issuer_details ON (Issuer_details.Issuer_id=Card_details.Issuer_id) 
   INNER JOIN PaymentType_details ON (PaymentType_details.PaymentType_id=Card_details.PaymentType_id) 
   INNER JOIN Merchant_details ON (Merchant_details.Merchant_id=Promotion_Merchant_details.Merchant_id) 
   INNER JOIN Promotion_Merchant_details ON (Promotion_Merchant_details.Promotion_id=Promotion_details.Promotion_id) 
   INNER JOIN Promotion_Card_details ON (Promotion_details.Promotion_id=Promotion_Card_details.Promotion_id)

    into this order:

    FROM Promotion_details 
   INNER JOIN Promotion_Card_details ON (Promotion_details.Promotion_id=Promotion_Card_details.Promotion_id)
   INNER JOIN Card_details ON (Card_details.Card_id=Promotion_Card_details.Card_id) 
   INNER JOIN Issuer_details ON (Issuer_details.Issuer_id=Card_details.Issuer_id) 
   INNER JOIN PaymentType_details ON (PaymentType_details.PaymentType_id=Card_details.PaymentType_id) 
   INNER JOIN Promotion_Merchant_details ON (Promotion_Merchant_details.Promotion_id=Promotion_details.Promotion_id) 
   INNER JOIN Merchant_details ON (Merchant_details.Merchant_id=Promotion_Merchant_details.Merchant_id)
