Error with SQL Server Stored Procedure & C# -


I am developing a stored procedure to obtain a register from the table, so I created the following query to get it : 

  Alternate Processes [DBO]. [Process_odd] @CodeCCNINT, Nomodes Varna (500), @ Kod Mate varchar (500) as Ghora varchar (50); Set @ hora = (ra_hpl_horarios_planificacion), select b.man_nomhor at Hpl_codman = b.man_codigo where an .hpl_codcil = 100 and a.hpl_codemp = (select emp_codigo from pla_emp_empleado where emp_nombres_apellidos = @NomDoce) and a.hpl_codmat = @ codMate and a.hpl_descripcion = @codSeccion) @hora end   
 I have this query is tested (query stored procedure with the query) and it works just fine in my SQL server console Does. The problem is that when I call it from C #, I still do not try to do the work! Apart from this, I tried to develop a stored procedure with the output parameter but there were no results.  
 In addition, I have other ways to try (which is very good and works fine!):  
  select an internal b.man_nomhor ra_hpl_horarios_planificacion ra_man_grp_horb but one. Hpl_codman = b.man_codigo on where one. Hpl_codcil = 100 and one. Hpl_codemp = (select emp_codigo from pla_emp_empleado where Emp_nombres_apellidos = 'Julio Escobar') and a.hpl_codmat = 'FONO-I' and a.hpl_descripcion = 1;   
 Here's my code is C # (My solution 11000):  
  public string Horrios (Int Sekgian, string Nomdest, string Codmat) {cn.Open (); CMD Connection = CN; Cmd.CommandText = "select b.man_nomhor from ra_hpl_horarios_planificacion Select emp_codigo on a.hpl_codman = b.man_codigo where a.hpl_codcil = 100 and a.hpl_codemp = (pla_emp_empleado) where Emp_nombres_apellidos = '" + + NomDocent "') and a. Hpl_codmat = ' "+ CodMate +"' and. Hpl_descripcion = ' "+ Seccion +"' '; Dr = cmd.ExecuteReader (); if (Dr. Acsaro) {if (dr.Read ()) {msj = Dr [0] .tostring ();}} Cn.close (); Return MSJ;}   
 When I run my Visual Studio, it does not show any errors, Rather it sets an empty STRING like MSJ = "" in the transcript of MSJX " ;  
 It should be really easy, but this is just (trust) I have worked so hard to solve with Bino results, please help!  
  
 
 
 It looks like  Seccion  (and thus  a. Hpl_descripcion ) are integers, but your query is keeping Epoproft around it like a literal  
 Try removing apostrophes:  
  ... + "'And a.plpl_descripcion =" + peak;   
 If this is indeed the issue, then the parameter of your query can eliminate these types of errors:  
  cmd.CommandText = ".. And a.hpl_codemp = (select Emp_codigo from Emp_nombres_apellidos = @NomDocent) and a.hpl_codmat = @CodMate and a.hpl_descripcion = @ Seccion "; CMD. Adpameter with value ("@omomodocent", nomadocent); CMD. Adapamator with value ("@ kodmatt", codmat); Cmd.AddParameterWithValue ("@ Seccion, Seccion); dr = cmd.ExecuteReader ();

c - Mpirun hangs when mpi send and recieve is put in a loop -

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...
