# AdvancedSQL

The best Java query builder/SQL connector.



## What's AdvancedSQL?

AdvancedSQL is a SQL query builder and/or connector that helps you to generate/modify information on the database without even have to write any line of SQL code, which sometimes is kindof boring and tiring. AdvancedSQL is the best exit for that developers who wants to continue coding without having to write out-of-syntax code (SQL queries) on Java code.



## Download

Download the latest JAR: https://github.com/DenzelCode/AdvancedSQL/releases/latest



## Dependency for maven:

```



    com.code

    advancedsql

    2.0.0

    system

    ${project.basedir}/lib/AdvancedSQL.jar



```



## Examples:

**Connect to the Database:**

There is no need to create the database manually, AdvancedSQL does it for you.

```java

import com.code.advancedsql.*;



try {

    MySQL mySQL = new MySQL("127.0.0.1", 3306, "root", "password", "database");



    if (mySQL.isConnected()) {

        System.out.println("Connected!");

    }

} catch (SQLException e) {

    e.printStackTrace();

}

```



**Create table:**

```java

import com.code.advancedsql.*;

import com.code.advancedsql.table.ITable;



try {

    MySQL mySQL = connect();



    // Table

    ITable table = mySQL.table("users");



    // Create table

    Create create = table.create().ifNotExists();



    // Table columns

    create.id();

    create.string("first_name");

    create.string("last_name");

    create.string("test");



    Boolean result = create.execute();



    // Print query string and result.

    System.out.println(create);

    System.out.println(result);

} catch (SQLException e) {

    e.printStackTrace();

}

```



**Alter table:**

```java

import com.code.advancedsql.*;

import com.code.advancedsql.query.action.Add;

import com.code.advancedsql.query.action.Modify;



try {

    MySQL mySQL = connect();



    // Alter columns

    Alter alter = mySQL.table("users").alter();



    // Add columns

    Add add = alter.add();

    add.string("token").nullable();

    add.string("connection_id").nullable();



    // Drop columns

    com.code.advancedsql.query.action.Drop drop = alter.drop();

    drop.column("test");



    // Modify columns

    Modify modify = alter.modify();

    modify.integer("connection_id").nullable();



    // Execute query

    Boolean result = alter.execute();



    // Print query string and result.

    System.out.println(alter);

    System.out.println(result);

} catch (SQLException e) {

    e.printStackTrace();

}

```



**Insert:**

```java

import com.code.advancedsql.*;



try {

    MySQL mySQL = connect();



    // Insert

    Insert query = mySQL.table("users").insert();

    

    query.field("first_name", "Denzel");

    query.field("last_name", "Code");

    

    int execute = query.execute();



    // Print query string and result.

    System.out.println(query);

    System.out.println(execute);

} catch (SQLException e) {

    e.printStackTrace();

}

```



**Insert HashMap:**

```java

import com.code.advancedsql.*;



try {

    MySQL mySQL = connect();



    // Insert

    Insert query = mySQL.table("users").insert(new HashMap<>(){{

        put("first_name", "Denzel");

        put("last_name", "Code");

    }});

    int execute = query.execute();



    // Print query string and result.

    System.out.println(query);

    System.out.println(execute);

} catch (SQLException e) {

    e.printStackTrace();

}

```



**Update:**

```java

import com.code.advancedsql.*;



try {

    MySQL mySQL = connect();



    // Update

    Update query = mySQL.table("users").update().where("first_name = ?", "Denzel");

    

    query.field("token", "Advanced");

    

    int execute = query.execute();



    // Print query string and result.

    System.out.println(query);

    System.out.println(execute)p

} catch (SQLException e) {

    e.printStackTrace();

}

```



**Update HashMap:**

```java

import com.code.advancedsql.*;



try {

    MySQL mySQL = connect();



    // Update

    Update query = mySQL.table("users").update(new HashMap<>(){{

        put("token", "Advanced");

    }}).where("first_name = ?", "Denzel");

    int execute = query.execute();



    // Print query string and result.

    System.out.println(query);

    System.out.println(execute)p

} catch (SQLException e) {

    e.printStackTrace();

}

```



**Select:**

```java

import com.code.advancedsql.*;



try {

    MySQL mySQL = connect();



    // Select

    Select query = mySQL.table("users").select();

    Map fetch = query.fetch();



    // Print query string and result.

    System.out.println(query);

    System.out.println(fetch);

} catch (SQLException e) {

    e.printStackTrace();

}

```



**Select with join:**

```java

import com.code.advancedsql.*;

import com.code.advancedsql.query.action.Add;

import com.code.advancedsql.query.action.Modify;

import com.code.advancedsql.table.ITable;



try {

    MySQL mySQL = connect();



    // Create information table

    ITable table = mySQL.table("information");



    // Delete table if exists.

    if (mySQL.table("information").exists()) table.drop().execute();



    // Create table

    Create create = table.create();



    // Table columns

    create.id();

    create.integer("user_id").nullable();

    create.string("address").nullable();

    Boolean execute = create.execute();



    // Print query and result.

    System.out.println(create);

    System.out.println(execute);



    // Insert value

    table.insert(new HashMap<>(){{

        put("user_id", 1);

        put("address", "20 Cooper Square");

    }}).execute();



    table = mySQL.table("users");



    Select query = table.select(new String[]{"information.address", "users.first_name"})

            .innerJoin("information")

            .on("users.id = information.user_id")

            .where("first_name = ?", "Denzel");



    Map user = query.fetch();



    // Print query and result.

    System.out.println(query);

    System.out.println(user);

} catch (SQLException e) {

    e.printStackTrace();

}

```



**Delete:**

```java

import com.code.advancedsql.*;



try {

    MySQL mySQL = connect();



    // Delete

    Delete query = mySQL.table("users").delete().where("first_name = ?", "Denzel");

    int execute = query.execute();



    // Print query and result.

    System.out.println(query);

    System.out.println(execute);

} catch (SQLException e) {

    e.printStackTrace();

}

```



**Truncate:**

```java

import com.code.advancedsql.*;



try {

    MySQL mySQL = connect();



    // Truncate table

    Truncate query = mySQL.table("users").truncate();

    Boolean execute = query.execute();



    // Print query and result.

    System.out.println(query);

    System.out.println(execute);

} catch (SQLException e) {

    e.printStackTrace();

}

```



**Drop:**

```java

import com.code.advancedsql.*;



try {

    MySQL mySQL = connect();



    // Drop table

    Drop query = mySQL.table("users").drop();

    Boolean execute = query.execute();



    // Print query and result.
