README
ObjectiveSQL is an ORM framework in Java based on ActiveRecord pattern, which encourages rapid development and clean, codes with the least, and convention over configuration.
### Key Features
- With one annotation your `Class` has fully featured capabilities of SQL programming
- Easy to relational(`has_one`, `has_many` and `belongs_to`) query and paged query
- Writing SQL expressions(`arithmetic`, `comparison` and `logical`) using Java syntax
### Why ObjectiveSQL
- If your project focuses on data analysis based on relation database, and a lot of arithmetic expressions in SQL statement. ObjectiveSQL will help you write expressions conveniently and safely using Java syntax
- If you don’t want to write Java codes of database access and various configuration files, ObjectiveSQL's dynamic code generation will help you access the database without coding
### Performance(Oracle JMH)
### Installation
##### IntelliJ IDEA plugin installation
`Preferences/Settings` -> `Plugins` -> `Search with "ObjectiveSql" in market` -> `Install`
##### Maven dependencies
```xml
com.github.braisdom
objective-sql
1.4.6
```
```xml
com.github.braisdom
objsql-springboot
1.3.4
```
Refer to the [pom.xml](https://github.com/braisdom/ObjectiveSql/blob/master/examples/mysql/pom.xml#L67) for more configuration
### Examples
ObjectiveSQL provides full example for various databases below, You can open it directly with IntelliJ IDEA as a standalone project. In fact, they are not just examples, but also unit tests of ObjectiveSQL in various databases.
If you want to run without configuration, you can try: [SQLite](https://github.com/braisdom/ObjectiveSql/tree/master/examples/sqlite)
Others: [MySQL](https://github.com/braisdom/ObjectiveSql/tree/master/examples/mysql), [Oracle](https://github.com/braisdom/ObjectiveSql/tree/master/examples/oracle), [MS SQL Server](https://github.com/braisdom/ObjectiveSql/tree/master/examples/sqlserver), [PostgreSQL](https://github.com/braisdom/ObjectiveSql/tree/master/examples/postgres), [Spring Boot](https://github.com/braisdom/ObjectiveSql/tree/master/examples/springboot-sample)
#### Simple SQL programming without coding
> You define just a JavaBean with annotations
```java
@DomainModel
public class Member {
private String no;
@Queryable
private String name;
private Integer gender;
private String mobile;
private String otherInfo;
@Relation(relationType = RelationType.HAS_MANY)
private List orders;
}
```
##### Persistence
```java
Member.create(newMember);
Member.create(new Member[]{newMember1, newMember2, newMember3}, false);
Member.update(1L, newMember, true);
Member.update("name = 'Smith => Jackson'", "name = ?", "Alice");
Member.destroy(1L);
Member.destroy("name = ?", "Mary");
```
##### Counting and querying
```java
Member.countAll();
Member.count("id > ?", 1);
Member.queryByPrimaryKey(1);
Member.queryFirst("id = ?", 1);
Member.query("id > ?", 1);
Member.queryAll();
```
##### Paged querying
```java
Page page = Page.create(0, 10);
PagedList members = Member.pagedQueryAll(page, Member.HAS_MANY_ORDERS);
```
##### Relation querying
```java
Member.queryAll(Member.HAS_MANY_ORDERS);
Member.queryByPrimary(1, Member.HAS_MANY_ORDERS);
Member.queryByName("demo", Member.HAS_MANY_ORDERS);
...
```
### Complex SQL programming
```java
Order.Table orderTable = Order.asTable();
Select select = new Select();
// In ObjectiveSQL, Java operator can be overloaded
select.project(sum(orderTable.amount) / sum(orderTable.quantity) * 100)
.from(orderTable)
.where(orderTable.quantity > 30 &&
orderTable.salesAt.between("2020-10-10 00:00:00", "2020-10-30 23:59:59"))
.groupBy(orderTable.productId);
```
```sql
SELECT SUM(`T0`.`amount`) / SUM(`T0`.`quantity`) * 100
FROM `orders` AS `T0`
WHERE `T0`.`quantity` > 30 AND
`T0`.`sales_at` BETWEEN '2020-10-10 00:00:00' AND '2020-10-30 23:59:59')
GROUP BY `T0`.`product_id`
```
