+# MySQL-API
+Simple Java API for MySQL
+
+## Usage
+
+### Init
+```Java
+MySQL sql = new MySQL();
+```
+
+### Set Credentials
+```Java
+sql.setHost("localhost");
+sql.setUser("sqluser");
+sql.setPassword("sqlpassword");
+sql.setDb("database");
+
+sql.setPort(3306); // Optional. Default: 3306
+sql.setDebug(false); // Optional. Default: false
+```
+
+
+### Connect to MySQL
+```Java
+boolean: sql.connect();
+```
+
+### Checks
+```Java
+boolean: isConnected();
+boolean: isDebug();
+```
+
+### MySQL Data interaction
+```Java
+boolean: sql.tableInsert("myTable", "name, age", "Robert", "32"); // INSERT Statement
+boolean: sql.rowUpdate("myTable", new UpdateValue("age", "45"), "name = 'Robert'"); // UPDATE Statement
+CachedRowSetImpl: sql.rowSelect("myTable", "*", "name = 'Robert'"); // SELECT Statement
+boolean: sql.custom("DELETE * FROM myTable;"); // Custom SQL Statement
+```
+ **Tip**
+ `CachedRowSetImpl` is like ResultSet
+ ```Java
+ CachedRowSetImpl res = sql.rowSelect(...);
+ while(res.next()) {
+    System.out.PrintLn(res.getString("myValue"));
+ }
+ 
+ ```
+
+### Close Connection
+```Java
+sql.close();
+```
+
