php - Can I use name of the column as parameter in PDO? -


I am trying to execute it: 

  $ colparam = 'abcd' ; $ Stmt = $ db- & gt; Ready (select "Select?" $ Stmt-> Operate (array ($ colparam)); $ rows = $ stmt- & gt; Get all (PDO :: FETCH_ASSOC);   
 And it is not working (no error, just empty array as a result).  
 Instead it works fine:  
  $ Stmt = $ db- & gt; Ready (select "Coal order of coal ASC as ACCD ASC"); $ Stmt-> Executed (); $ rows = $ stmt-> Get all ( PDO :: FETCH_ASSOC);   
 So what's the name of the column in the PDO Is there a hold with the use of parameters in the form of?   
 
 
 No, you have a database object in MySQL ( Table, column etc.).  
 When you think that what exactly is a prepared statement, it is considered complete as MySQL prepares a query execution plan. This can not be done when the database is included in objects.  
 I can certainly The more documentation will actually be covered which actually makes a prepared statement (beyond its apparent use for the paramatization)

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...
