sql server - How to check numeric value in sql? -


This is my code. I want only numeric characters if it is other than numeric, then do not print.

Here is the substring of one of the MMSG strings, which is dynamically created. So I can not change the type of 'MMS int', '3' or '4', ' Etc. MGGM includes commas, so I want to check for numeric. Consider a comma as numerical () numeric. I give 1 as the result. How can it be managed? 

  Declare @ MSG varchar (5) Set @ mgg = ', 5' if (numerical (mmsg) = 1) print 'numeric' - logic and    
 
 
 The messengers are definitely specifications they are discussing well in the community See for some discussions here.  
 What you really need to do is not quite clear between the questions and the comments, but you can get it as simple as checking in order to ensure that there are no commas Is:  
  DECLARE @msg VARCHAR (5) SET @msg = ', 5' IF nanameric (mmsg) = 1 and four indices (',', @ msg, 1) = 0 print 'Numeric' - argument END   
 How to do a better IsNumeric, see similar questions for more ideas on this Not.

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.
