# Lumus sql builder

## About project

Lumus SQL Builder is a Rust library that allows you to programmatically and intuitively construct complex SQL queries for simple projects. It supports a variety of SQL operations, including column selection, joins, WHERE clauses, grouping, sorting, and more.

## Features

-   Table creation

-   Data insertion

-   Data selection with support for DISTINCT, GROUP BY, ORDER BY, LIMIT, and OFFSET

-   A simple way to make WHERE clauses

## Example Usage

### Creating a Table

```rust

use lumus_sql_builder::sqlite::{CreateTable, Column};

fn main() {

    let create_table = CreateTable::new("employees", vec![

        Column::new("id").integer().primary_key().auto_increment(),

        Column::new("name").text().not_null(),

        Column::new("age").integer().not_null(),

        Column::new("department").text().default("'Undefined'"),

        Column::new("salary").real(),

        Column::new("hired_date").datetime(),

        Column::new("manager_id").integer()

    ]);

    println!("{}", create_table.build().unwrap());

}

```

### Output

```sql

CREATE TABLE employees (

    id INTEGER PRIMARY KEY AUTOINCREMENT,

    name TEXT NOT NULL,

    age INTEGER NOT NULL,

    department TEXT DEFAULT 'Undefined',

    salary REAL,

    hired_date DATETIME,

    manager_id INTEGER

);

```

### Inserting Data

```rust

use lumus_sql_builder::sqlite::Insert;

fn main() {

    let insert = Insert::new("employees").values(vec![

        ("name", "John"),

        ("age", "30"),

        ("department", "IT"),

        ("salary", "5000.00"),

        ("hired_date", "2024-03-20"),

        ("manager_id", "1")

    ]);

    println!("{}", insert.build().unwrap());

}

```

### Output

```sql

INSERT INTO employees (name, age, department, salary, hired_date, manager_id) VALUES ('John', '30', 'IT', '5000.00', '2024-03-20', '1');

```

### Selecting Data

```rust

use lumus_sql_builder::sqlite::{Select, Where};

fn main() {

    let select = Select::new("employees")

        .columns("name, age, department")

        .condition(Where::from("age > 25").build())

        .order("age DESC")

        .limit(10);

    println!("{}", select.build().unwrap());

}

```

### Output

```sql

SELECT name, age, department FROM employees WHERE age > 25 ORDER BY age DESC LIMIT 10;

```
