How do I store a c++ byte array in mySQL table binary(16) field using connector c++?

Question

I am trying to store a c++ byte array in a mySQL binary(16) field.

mysqlTable is an instance of mysqlx::Table class that works OK with other variable types.

data -> is the table field name of type binary(16)

data1 -> is the table field name of type binary(1)

What I have tried so far:

unsigned char cArray[16];

mysqlTable.insert("data").values(cArray).execute();

I have also tried:

unsigned char * pcArray = new unsigned char[16];

mysqlTable.insert("data").values(pcArray).execute();

And this works just fine:

unsigned char cOneChar;

mysqlTable.insert("data1").values(cOneChar).execute();

The error I get is form the compiler:

see reference to function template instantiation 'mysqlx::TableInsert &mysqlx::TableInsert::values<BYTE*>(BYTE *)' being compiled
    error C2783:    'void mysqlx::internal::Args_processor<mysqlx::internal::Table_insert_detail::Add_value,mysqlx::internal::Table_insert_detail::Add_value::Impl *>::process_args(D,C)': could not deduce template argument for '__formal'
                     with
            [
                D=mysqlx::internal::Table_insert_detail::Add_value::Impl *
            ]

Does anyone know how to do this?

Late to the party but I struggled to find a neat way to do this. Using msqlx::bytes worked well. So you could adapt your code:

int n=16;
unsigned char cArray[n];
unsigned char const *Ptr=cArray;
mysqlx::bytes bytes{Ptr,n};
mysqlTable.insert("data").values(bytes).execute();
