using Mono.Data.Sqlite;

using System;

using System.Data;

using System.IO;

using UnityEngine.UI;

interface enables you to implement a Connectionclass

private string conn, sqlQuery;

IDbConnection dbconn;

IDbCommand dbcmd;

private IDataReader reader;

Database Name

string DatabaseName = "Yourdatabasename.s3db";

For all platform

string filepath = Application.dataPath + "/Plugins/" + DatabaseName;

Application database Path android

string filepath = Application.persistentDataPath + "/" + DatabaseName;

DatabBase Path for Android

 // If not found on android will create Tables and database Debug.LogWarning("File \"" + filepath + "\" does not exist. Attempting to create from \"" + Application.dataPath + "!/assets/Employers"); // #UNITY_ANDROID WWW loadDB = new WWW("jar:file://" + Application.dataPath + "!/assets/Employers.s3db"); while (!loadDB.isDone) { } // then save to Application.persistentDataPath File.WriteAllBytes(filepath, loadDB.bytes); 

Databasde SQLite Path IOS

// #UNITY_IOS

var loadDb = Application.dataPath + "/Raw/" + DatabaseName; // this is the path to your StreamingAssets in iOS // then save to Application.persistentDataPath File.Copy(loadDb, filepath); 

DatabBase Path for Windows Phone :

// #UNITY_WP8

var loadDb = Application.dataPath + "/StreamingAssets/" + DatabaseName; // this is the path to your StreamingAssets in iOS //then save to Application.persistentDataPath File.Copy(loadDb, filepath); 

DatabBase Path for WINRT

// #UNITY_WINRT

 var loadDb = Application.dataPath + "/StreamingAssets/" + DatabaseName; // this is the path to your StreamingAssets in iOS // then save to Application.persistentDataPath File.Copy(loadDb, filepath); 

open Database SQlite Unity connection

 conn = "URI=file:" + filepath; Debug.Log("Stablishing connection to: " + conn); dbconn = new SqliteConnection(conn); dbconn.Open(); 

To Create Table Sqlite

This Example:

Table Name (Staff) Have ID is PRIMARY KEY , Name, Address

 string query; query = "CREATE TABLE Staff (ID INTEGER PRIMARY KEY AUTOINCREMENT, Name varchar(100), Address varchar(200))"; try { dbcmd = dbconn.CreateCommand(); // create empty command dbcmd.CommandText = query; // fill the command reader = dbcmd.ExecuteReader(); // execute command which returns a reader } catch (Exception e) { Debug.Log(e); } 

To Select Sqlite

string Name_readers, Address_readers; using (dbconn = new SqliteConnection(conn)) { dbconn.Open(); //Open connection to the database. IDbCommand dbcmd = dbconn.CreateCommand(); string sqlQuery = "SELECT Name, Address " + "FROM Staff";// table name dbcmd.CommandText = sqlQuery; IDataReader reader = dbcmd.ExecuteReader(); while (reader.Read()) { Name_readers = reader.GetString(0); Address_readers = reader.GetString(1); Debug.Log(" name =" + Name_readers + "Address=" + Address_readers); } reader.Close(); reader = null; dbcmd.Dispose(); dbcmd = null; dbconn.Close(); 

To Insert Sqlite

using (dbconn = new SqliteConnection(conn)) { dbconn.Open(); //Open connection to the database. dbcmd = dbconn.CreateCommand(); sqlQuery = string.Format("insert into Staff (name, Address) values (\"{0}\",\"{1}\")", name, Address);// table name dbcmd.CommandText = sqlQuery; dbcmd.ExecuteScalar(); dbconn.Close(); } Debug.Log("Insert Done "); 

To Update Sqlite

 using (dbconn = new SqliteConnection(conn)) { dbconn.Open(); //Open connection to the database. dbcmd = dbconn.CreateCommand(); sqlQuery = string.Format("UPDATE Staff set name = @name ,address = @address where ID = @id "); SqliteParameter P_update_name = new SqliteParameter("@name", update_name); SqliteParameter P_update_address = new SqliteParameter("@address", update_address); SqliteParameter P_update_id = new SqliteParameter("@id", update_id); dbcmd.Parameters.Add(P_update_name); dbcmd.Parameters.Add(P_update_address); dbcmd.Parameters.Add(P_update_id); dbcmd.CommandText = sqlQuery; dbcmd.ExecuteScalar(); dbconn.Close(); Search_function(t_id.text); } 

To Search By ID

using (dbconn = new SqliteConnection(conn)) { string Name_readers_Search, Address_readers_Search; dbconn.Open(); //Open connection to the database. IDbCommand dbcmd = dbconn.CreateCommand(); string sqlQuery = "SELECT name,address " + "FROM Staff where id =" + Search_by_id;// table name dbcmd.CommandText = sqlQuery; IDataReader reader = dbcmd.ExecuteReader(); while (reader.Read()) { Name_readers_Search = reader.GetString(0); Address_readers_Search = reader.GetString(1); data_staff.text += Name_readers_Search + " - " + Address_readers_Search + "\n"; Debug.Log(" name =" + Name_readers_Search + "Address=" + Address_readers_Search); } reader.Close(); reader = null; dbcmd.Dispose(); dbcmd = null; dbconn.Close();
