sql - Sqlite database with single row -


I want to create a SQLite database table with one line and several columns. The entire line will be updated every time.

I can create tables in sqlite but it is not working for the first time to update the entire line.

The update entire line first works only after the INSERT command. Instead of making the INSERT command the first time, can it be prepared that it is possible to execute the UPDATE command as a host?

I am taking the following steps:

$ sqlite3 test.db 

  sqlite & gt; Table company (ID primary primary key not blank, name text, age int); SQLite & gt; Update company set id = 1, name = 'test', age = 30; SQLite & gt; Choose from company *; SQLite & gt;   
 Here the statement is returning nothing.  
 Is there any restriction on SQL to start using the UPDATE command?  
  
 
 
 You ignore how SQL works that you do not update anything and hope After that there is a magical presence of an appearance.  
 You must first include one.

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...
