# libsl3, a C++ interface for SQLite 3.x

libsl3 is designed to enable comfortable and efficient communication with a

SQLite database based on its natural language, which is SQL.

libsl3 originated back at a time when C++11 was new.

It has remained stable to support existing users for quite a while, over a decade.

With the arrival of C++23, development has been restarted. The minimum required C++ standard is now C++17.

The goal is to keep the interface stable, but using a newer C++ standard might justify some breaking changes.

For people seeking the old version, release v1.1.31001 preserves the original C++11 state with CMake 2.8 support.

**The full documentation for libsl3 can be found here:**

## A short usage example

```cpp

#include 

#include 

#include 

int main()

{

  using namespace sl3;

  // define a db

  Database db(":memory:");

  // run commands against the db

  db.execute("CREATE TABLE tbl(f1 INTEGER, f2 TEXT, f3 REAL);");

  // create a command with parameters

  auto cmd = db.prepare("INSERT INTO tbl (f1, f2, f3) VALUES (?,?,?);");

  //add some data

  cmd.execute(parameters(1, "one", 1.1));

  cmd.execute(parameters(2, "two", 2.2));

  // access the data

  Dataset ds = db.select("SELECT * FROM tbl;");

  // Dataset is a container

  assert(ds.size()==2);

  // A row in a dataset is also a container

  auto row = ds[0] ;

  assert(row.size()==3);

  // Type info for each field s available

  assert ( row[0].type() == Type::Int ) ;

  assert ( row[1].type() == Type::Text ) ;

  assert ( row[2].type() == Type::Real ) ;

  // there is also iterator access

  for(const auto& row  :ds) {

      for (const auto& field : row) {

          std::cout << field << " " ;

      }

      std::cout << std::endl;

  }

}

```

This will output

```bash

1 one 1.1

2 two 2.1

```
