Lightweight C++ wrapper for SQLite


Lightweight C++ wrapper for SQLite.


  • C++11 compiler
  • SQLite 3


Let's open a database file and read some rows:

#include "NLDatabase.h"

using namespace std;
using namespace NL::DB;

int main(int argc, const char * argv[]) {

    Database db( "test.sqlite" );

    auto results = db.query( "SELECT * FROM test WHERE name <> ?" ).select( "TOM" );

    for ( auto & row : results ) {
        cout << "column[0]=" << row[ 0 ].as_string() << endl;

Check out the demo for more examples.


It's a single source file and a header, just drop into your project, link sqlite3 and that's it.


To run the simple demo, use the Xcode project or build it on the command line like this:

sqlite3 test.sqlite < test.sql
clang -o test -std=c++11 -lsqlite3 -lstdc++ main.cpp

Known problems

  • There is no error checking. None. Your queries must be perfect.
  • If you look at the way the results are retrieved, you will realize that you can only iterate through them ONCE. I didn't see an obvious way to express this in code and make it impossible syntactically, so it's simply something you need to keep in mind.

Personal note

If you use NLDatabase in a project, I'd love to hear about it. Please do let me know at Thanks!

Goes well with NLTemplate and possibly Mongoose.
