sql server 2008 - Update specific records based on some group -


I am using SQL Server 2008 R2 I

Near Database Table contains some user data: 

  id UserId Sys Dia ReadType DataId IsDeleted 1 10 98 65 Final 1390556024216 0 2 10 99 69 Average 1390556024216 0 3 10 102 96 Final 1390562788540 0 4 10 102 96 Average 1390562788540 0 5 11 130 98 Final 1390631241547 0 6 11 130 98 Average 1390631241547 0 7 2 285 199 First 1390770562374 0 8 2 250 180 Last 1390770562374 9 2 267 189 Average 1390770562374 0 10 1 258 180 First 13 9 1191009457 0 11 1 258 180 Final 1391191009457 0 12 1 258 180 Avg 1391191009457 13 137 285 199 Extras 1391191009457 0 14 22 110 78 Final 1391549 208338 15 15 22 123 83 Previous 1391549208349 0   
 In this table, there are records that are similar to  same data ID , but  separate readings type .  
 I want to set  IsDeleted = 1  for the record containing  ReadingType = 'last'  and  ReadingType = 'average'  With the same data id, sis, die and user id .  
 Then the desired result may be shaken:  
  ID UserId read the Sys Dia DataId IsDeleted 1 10 98 65 Final 1390556024216 0 2 10 99 69 Average 1390556024216 0 3 10 102 96 Last 1390562788540 1 4 10 102 96 Average 1390562788540 0 5 11 130 98 Final 1390631241547 1 6 11 130 98 Average 1390631241547 0 7 2 285 199 First 1390770562374 0 8 2 250 180 Last 1390770562374 9 2 267 189 Average 1390770562374 0 10 1 258 180 First 13 9 1191009457 0 11 1 258 180 Final 1391191009457 1 12 1 258 180 Average 1391191009457 0 13 1 285 199 Extra 1391191009457 0 14 22 110 78 Final 13 91549208338 15 15 123 123 Final 1391549208349 0   
 Here Record marked with  id 3, 5 and 11  as  deleted  As they can help someone else with any other record, such as the same userid, sis, die, data id and reading type = "last", how to find and update any such record   
  "itemprop =" text "> 
 Just update with the current update:  
  update t Set isDeleted = 1 where reading type = 'last' and current (select from * T as T1 WHERE T1 reading type = 'average' and T1. Etaid = Tikdetaid and T1. SYS = T. SS and T1 Dia = TDIA and T1. User id = t user id)

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...
