[Moesat]

The sqldatabase is working fine when I run in editor but it does not work after build. This problem started happen after updated the unity to 5.6.0f3 from old one. The sql script is as below. I have tired all I can do.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Mono.Data.Sqlite;
using System;
using System.Data;

public class DataStorage : MonoBehaviour
{
    public V v;

    string conn;
    int CheckOk = 0;

    private string Answer;

    public string Load(string Code)
    {
        if (Code.Length != 0)
        {
            CheckOk = 0;
            int x = Int32.Parse(Code);
            StartCoroutine(Wait());
            IDbConnection dbconn;
            dbconn = (IDbConnection)new SqliteConnection(conn);
            dbconn.Open(); //Open connection to the database.
            IDbCommand dbcmd = dbconn.CreateCommand();
            string sqlQuery = "SELECT Code,Ans FROM Answers";
            //string sqlQuery = "CREATE TABLE IF NOT EXISTS Answers (Code INTEGER NOT NULL PRIMARY KEY, Ans VARCHAR(40))";
            dbcmd.CommandText = sqlQuery;
            IDataReader reader = dbcmd.ExecuteReader();
            while (reader.Read())
            {
                int CodeM = reader.GetInt32(0);
                string Ans = reader.GetString(1);
                if (x == CodeM)
                {
                    Answer = Ans;
                    CheckOk = 1;
                    break;
                }
            }
            if (CheckOk == 0)
            {
                Answer = "I don't know what you mean.";
            }
            reader.Close();
            reader = null;
            dbcmd.Dispose();
            dbcmd = null;
            dbconn.Close();
            dbconn = null;
        }
        else
        {
            Answer = "I don't know what you mean.";
        }
        return (Answer);
    }

    public void Save(string Code,string Ans)
    {
        int x = Int32.Parse(Code);
        Debug.Log(x);
        StartCoroutine(Wait());
        IDbConnection dbconn;
        dbconn = (IDbConnection)new SqliteConnection(conn);
        dbconn.Open(); //Open connection to the database.
        IDbCommand dbcmd = dbconn.CreateCommand();
        string sqlAdd = "INSERT INTO Answers VALUES('" + x + "','" + Ans + "')";
        dbcmd.CommandText = sqlAdd;
        IDataReader reader = dbcmd.ExecuteReader();
        reader.Close();
        reader = null;
        dbcmd.Dispose();
        dbcmd = null;
        dbconn.Close();
        dbconn = null;
    }

    private IEnumerator Wait()
    {
        conn = "URI=file:" + Application.dataPath + "/StreamingAssets/Memory.db"; //Path to database.
        v.SystemLogEditor(conn);
        Debug.Log(conn);
        yield return conn;
    }

}

This is on editor.

This is after build.

As you can see, there is no reply log in system log. Please help me.

Oh! It solved! I re-imported the sqlite3.dll file from this link and it works fine.
Here the link to get the zip file of Sqlite3.
