sqlite table code manager? - c++

Question

Fairly new to sqlite (and sql). I have several tables I need to generate with several column names, which can change as I code (in c++). How do I manage them? Am I doing it right? There must be utility codes out there that's much better.
Edit: Specifically, I'd like to avoid run-time errors by having an abstraction of the table and field names at compile time (e.g. using #defines, but maybe something else is better).
E.g. I'm currently thinking about creating a class TableHandler that will:
sqlite *db;
....
TableHandler tb("TableName");
tb.addField("FirstName", "TEXT");
tb.addField("Id", "INTEGER");
tb.createTable(db); //calls sqlite3_exec("create table TableName(FirstName TEXT, Id INTEGER)");
tb.setEntry("FirstName", "bob");
tb.addEntry(); //calls sqlite3_exec("insert ...");
tb.createCode(stdout);
//this will generate
/*
#define kTableName "TableName"
#define kFirstName "FirstName"
#define kId "Id"
...anything else useful?
*/

I asked a similar question and it was down voted so i deleted it. I wrote some code to do the insert if you are interested. But i agreed with the negative comments that static SQL statements are less error prone. Not to mention less cpu intensive.
For insert i took a std::set of std::pair of std::string. The first string being the column name and the second string its value. And the Query returned a similar structure. I played with std::map and std::vector and std::unordered_set all of them would have different benefits here.
What would be great if you get around to it is a small utility program that could read a definition of a class and write all the SQL for you. I started this and gave up because of parsing the C++ header file got way to complicated for the time I would save on future projects.
Added
std::string Insert(std::string table, std::vector< std::pair<std::string,std::string> > row)
{
if (row.size()==0 || table.size()==0)
return "";
std::stringstream name,value;
auto it = row.begin();
name << "INSERT INTO " << table.c_str()<<"('" << (*it).first << "'";
value << "VALUES('" <<(*it).second << "'";
for ( ; it < row.end(); it++)
{
name << ", '" << (*it).first << "'";
value << ", '" <<(*it).second << "'";
}
name << ") ";
value << ");";
name << value.str();
return name.str();
}
