mysql - Aggregating a column by multiple date ranges in a single query -


मेरे पास 5 कॉलम के साथ एक MySQL तालिका है: 

  डिवाइस | नाम | दिनांक | स्रोत | आय   
 न तो  डिवाइस  और  नाम  और  स्रोत  अद्वितीय है।  
 I निम्नलिखित के लिए एसक्यूएल लिखने की कोशिश कर रहा हूं:  
  डिवाइस | नाम | स्रोत | आय (पिछले 3 दिनों के लिए) | आय (पिछले 9 दिनों के लिए) | आय (पिछले 12 दिनों के लिए)   
 ऐसा करने का सबसे अच्छा तरीका क्या है?   
 
 
 आपको सशर्त  SUM ()  के माध्यम से  मामला  कथन प्राप्त कर सकते हैं:  
  चुनें उपकरण, नाम, स्रोत, SUM (मामला जब UNIX_TIMESTAMP के बीच की तिथि (अब () - INTERVAL 3 दिन) और UNIX_TIMESTAMP (अब ()) आय के अंत में) Last_3_Days, SUM (केस के समय के बारे में दिनांक UNIX_TIMESTAMP (NOW () - INTERVAL 9 दिन) और UNIX_TIMESTAMP (अब ( )) THEN आय ईडीडी) अंतिम रूप से आपके डिवाइस के नाम से, स्रोत

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
