<h3 align="center">MySQL Toolkit</h3>
|
||||
|
||||
## About The Project
|
||||
This is a small project for quickly managing a MySQL database in Java. It makes everyday life with a database much easier.
|
||||
|
||||
### Installation
|
||||
1. Clone the repo
|
||||
```sh
|
||||
git clone https://github.com/germannewsmaker/sqltoolkit.git
|
||||
```
|
||||
2. Move the project into a package of your project (in most cases "sql")
|
||||
3. Ready! Have fun
|
||||
#### Maven comming soon
|
||||
|
||||
### Usage Examples
|
||||
1. Create a connection
|
||||
- Example of a constructor without optional specifications
|
||||
```java
|
||||
MySQLConnection connection = new MySQLConnection(hostname, username, password, database).connect();
|
||||
```
|
||||
- Example of a constructor with setting the logging level
|
||||
```java
|
||||
MySQLConnection connection = new MySQLConnection(hostname, username, password, database, LogLevelType.ALL).connect();
|
||||
```
|
||||
- Example of a constructor with optional login parameters
|
||||
```java
|
||||
MySQLConnection connection = new MySQLConnection(hostname, username, password, database, LoginParam.AUTO_RECONNECT, LoginParam.NO_SSL).connect();
|
||||
```
|
||||
#### Logging Levels
|
||||
- NONE - Sends nothing
|
||||
- LOW - Sends Warnings & Errors
|
||||
- ALL - Sends Infos, Warnings & Errors
|
||||
#### Login Parameters
|
||||
- DEFAULT *(useSSL=false&autoReconnect=true&useUnicode=yes&characterEncoding=UTF-8&useTimezone=true&serverTimezone=UTC)*
|
||||
- NO_SSL *(useSSL=false)*
|
||||
- USE_SSL *(useSSL=true)*
|
||||
- AUTO_RECONNECT *(autoReconnect=true)*
|
||||
- UTF8_ENCODING *(characterEncoding=UTF-8)*
|
||||
- USE_UNICODE *(useUnicode=yes)*
|
||||
- USE_TIMEZONE *(useTimezone=true)*
|
||||
- TIMEZONE_UTC *(serverTimezone=UTC)*
|
||||
2. Perform a standard SQL query
|
||||
- Get a ResultSet
|
||||
```java
|
||||
connection.getResultSet("default query", "parameters");
|
||||
```
|
||||
- Perform an update
|
||||
```java
|
||||
connection.update("query", "parameters");
|
||||
```
|
||||
3. Get something from a table with managers
|
||||
1. Getting a Result (For one result)
|
||||
```java
|
||||
String value = connection.getResult("query", "parameters")
|
||||
.getString("column");
|
||||
```
|
||||
2. Getting Results (For more than one)
|
||||
```java
|
||||
ArrayList<String> list = connection.getResult("query", "parameters")
|
||||
.getList("column");
|
||||
```
|
||||
3. Choosing Results
|
||||
```java
|
||||
connection
|
||||
.selectFrom("table")
|
||||
.where("column", "value")
|
||||
.limit(10)
|
||||
.getResult();
|
||||
```
|
||||
4. Choosing Results + Print the current statement
|
||||
```java
|
||||
connection.select()
|
||||
.from("table")
|
||||
.where("column", "value")
|
||||
.add("LIMIT 2,5")
|
||||
.printStatement();
|
||||
```
|
||||
4. Perform an update using managers
|
||||
1. Update a Table
|
||||
```java
|
||||
connection
|
||||
.update()
|
||||
.toTable("table")
|
||||
.where("column", "value")
|
||||
.set("column", "newValue")
|
||||
.update();
|
||||
```
|
||||
2. Generate a Table
|
||||
```java
|
||||
connection
|
||||
.update()
|
||||
.generateTable("table")
|
||||
.useID()
|
||||
.addField(new SQLField(SQLType.STRING, "column", 999))
|
||||
.addField(new SQLField(SQLType.STRING, "column2", 25))
|
||||
.create();
|
||||
```
