Connect to MySQL Server Database (MariaDB)

• Disable Windows Firewall !!

Connect to MySQL server database (MariaDB) using this plugin is very simple. Example code to connet from cordova android app as follow

function Connect(){
	
	var host   = "192.168.1.6";
	var user   = "budi";
	var pass   = "fWSs_pwZTFFLxU82";
	var port   = 3306;
	var dbname = "cordova_sql";
	
	cordova.plugins.MySQLDirect.Connect(host, user, pass, port, dbname, onSuccess, onError);
	
	function onSuccess(s){
        document.getElementById("dbinfo").innerText = s;
    }

	function onError(e){
        document.getElementById("dbinfo").innerText = e;
    }
	
}

Get Result From Query (Select)

to handle query result (select), we can use getQuery function. for example we will get the value from prov table as follow

function SelectTable(){
		 
	var qry = "select * from prov";
	
	cordova.plugins.MySQLDirect.getQuery(qry, onSuccess, onError);
	
	function onSuccess(s){
		
		var rs = JSON.parse(s); // parse output to JSON
		
		rs.forEach(function(obj){
			document.getElementById("prov_list").innerHTML += obj['id']+". "+obj['name']+"</br>";  
		});
    }

	function onError(e){
       alert(e);
    }
	
} 

Execute Query (Insert/Update/Delete)

to handle query like insert, update and delete we can use execQuery. for example we will add new record to prov table as follow

function AddRow(){
		 
	var qry = "insert into prov (id, name) values ('','Lombok Utara')";
	
	cordova.plugins.MySQLDirect.execQuery(qry, onSuccess, onError);
	
	function onSuccess(s){
        alert(s);
    }

	function onError(e){
       alert(e);
    }
	
}
