c# - Join Tables MySQL -


I have several tables and 2 sub-selections (UserRecord, customercards) which I would like to merge into 1 table UserRecord ======================== | Record id Username ======================== | 1 | Sara | | 1 | Tom | | 2 | Sara | | 2 | Kurt | | 3 | Free | ======================= Table: Consumer guard ====================== ====== | Record id Customer Name | ============================ | 1 | Jeff | | 2 | Alex | | 2 | Peter | ============================== This should be the result: =============== = ======================= | Record id Username Customer Name | ======================================= | 1 | Sara | - | | 1 | Tom | - | | 1 | - | Jeff | | 2 | Sara | - | | 2 | Kurt | - | | 2 | - | Alex | | 2 | - | Peter | | 3 | Free | - | =======================================

I have tried with left, right, left to right, external ... . Include Customer Rickload in Ur Inner as User Record from SELECT *; Rick on ur Id = number Record id;

What you want is not included, but a union: 

  Select the record ID, Username, tap as username from UNUserCord, select the record ID, username as the tap, customer name by customer name   
. .. which adds a record to just two tables. / p> 
 I will just add that the orders shown in the results you expected will not be. If the order is important then you should choose from this union and add a clear order buy clause to this external selection. Something like this: Select  
  SELECT * (select ID, Username, User Record, select UNION, Record ID, Username as Faucet, Customer Client with Customer Name), Record ID, Username, Customer Name

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
