database - Using return query in Postgres 9.0 function with composite type -


I have a function in Postgres that returns a set of the entire set when I return only with I am able to return to next; but with return query command, why is 

  create type return_type? AS (Paramayam characters vary, value character is different); - This returning rows two rows can make r.paramname just works fine or the function test replaces (i_param1 character separately, i_param2 character different) SETOF returns_type: = 'ROW1'; R.value: = 'myvalue1'; Go ahead r; R.paramname: = 'ROW1'; R.value: = 'myvalue1'; Go ahead r; Return; - With this command I get the same line of the resultet return query, select 'ROW1' as the paraName value unions do not get all the 'line 2' as 'myvalue1' in the form of paraName, the value of 'Myvalue2' in the form; Return; "Text" itemprop = "text"> 
 This works for me, also in Postgres 8.4:    
 You can create pre>  or change function function (i_param1 varchar, i_param2 varchar) instead of SETOF return_type $ function $ start return query select 'ROW1' :: varchar, 'myvalue1' :: varchar unions all 'Row2', 'myvalue2'; End $ $ func $ LANGUAGE plpgsql;   
 Your origin should only return an exception, because due to type mismatch, you need string literals  inserted  for mailing types. On the other hand, the column nickname Here are irrelevant: The function is not visible outside the body.

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

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...
