# sqlite_orm_lite

sqlite orm, C++20, simple, and easy to use.

Features:

- Minimalist: Only 500 lines of code. Easily adaptable to other databases.

- Modern C++20: Utilizes Template Metaprogramming (TMP) techniques, with no macros involved

- Intuitive: User-friendly and straightforward API

## Build

```bash

git clone https://github.com/faker2048/sqlite_orm_lite.git

cd sqlite_orm_lite

nix develop # to enter a development shell environment

mkdir build && cd build

cmake ..

make -j

ctest # to run tests

```

## Usage

```C++

struct MyCustomType {

  int id;

  std::string name;

  double height;

  auto sql_constructor() {

    return SqlConstructorBuilder()

        .SetTableName("MyCustomType")

        .AddColumn("id", &id)

        .AddColumn("name", &name)

        .AddColumn("height", &height)

        .Build();

  }

};

TEST(SqliteFileTest, InsertAndRetrieveData) {

  TmpDir tmp_dir{"InsertAndRetrieveData"};

  SqliteFile db_file(tmp_dir.path() / "test.db");

  db_file.EnsureTable(); // This will create the table

  MyCustomType data = {1, "Alice", 1.70};

  db_file.Insert(data); // Insert data into the database

  auto retrieved = db_file.GetTable();

  EXPECT_EQ(retrieved.size(), 1);

  EXPECT_EQ(retrieved[0].id, data.id);

  EXPECT_EQ(retrieved[0].name, data.name);

  EXPECT_DOUBLE_EQ(retrieved[0].height, data.height);

}

TEST(SqliteFileTest, InsertRowsAndRetrieveData) {

  TmpDir tmp_dir{"InsertRowsAndRetrieveData"};

  SqliteFile db_file(tmp_dir.path() / "test.db");

  db_file.EnsureTable(); // Ensures that the table exists

  std::vector data = {

      {1, "Alice", 1.70}, {2, "Bob", 1.80}, {3, "Charlie", 1.90}};

  db_file.InsertRows(data); // Insert multiple rows

  auto retrieved = db_file.GetTable();

  EXPECT_EQ(retrieved.size(), data.size());

  for (int i = 0; i < data.size(); ++i) {

    EXPECT_EQ(retrieved[i].id, data[i].id);

    EXPECT_EQ(retrieved[i].name, data[i].name);

    EXPECT_DOUBLE_EQ(retrieved[i].height, data[i].height);

  }

}

```
