elasticsearch speed comparison issue with sql

I compare the speed of Sql with ElasticSearch. I have 1.5 million data. But sql query runs faster than elastic search. I don't understand the problem.
Why is the word like query coming faster in sql?
My code for Sql
public static List<Sales> GetAllRecords(string itemType)
{
List<Sales> salesReports = new List<Sales>();
string sqlQuery = String.Format(#"SELECT * FROM dbo.Sales where Region like '%{0}%'", itemType);
using (SqlConnection connection = new SqlConnection(CONNECTION_STRING))
{
var result = connection.Query<Sales>(sqlQuery);
foreach (var item in result)
{
Sales global = new Sales()
{
Region = item.Region,
Country = item.Country,
Item_Type=item.Item_Type,
Order_Date=item.Order_Date,
Order_ID = item.Order_ID,
Order_Priority=item.Order_Priority,
Sales_Channel=item.Sales_Channel,
Ship_Date = item.Ship_Date,
Total_Cost=item.Total_Cost,
Total_Profit=item.Total_Profit,
Total_Revenue=item.Total_Revenue,
Units_Sold=item.Units_Sold,
Unit_Cost=item.Unit_Cost,
Unit_Price = item.Unit_Price
};
salesReports.Add(global);
}
return result.ToList();
}
}
My code for ElasticSearch.
I search the data that I indexed before with elasticsearch here.
public static List<Sales> ConfigureES(string inputText)
{
List<Sales> salesReports = new List<Sales>();
// 1. Connection URL's elastic search
var listOfUrls = new Uri[]
{
// here we can set multple connectionn URL's...
new Uri("http://localhost:9200/")
};
StaticConnectionPool connPool = new StaticConnectionPool(listOfUrls);
ConnectionSettings connSett = new ConnectionSettings(connPool);
ElasticClient eClient = new ElasticClient(connSett);
// var see = eClient.DeleteIndex(INDEX_NAME);
// check the connection health
var checkClusterHealth = eClient.ClusterHealth();
if (checkClusterHealth.ApiCall.Success && checkClusterHealth.IsValid)
{
// 2. check the index exist or not
var checkResult = eClient.IndexExists(INDEX_NAME);
if (!checkResult.Exists)
{
// Raise error to Index not avaliable
}
// Search particular text field
var searchResponse = eClient.Search<Sales>(s =>
s.Index(INDEX_NAME).From(0).Size(5000).Scroll("10m")
.Query(q => q.Match(m => m.Field(f => f.Region).Query(inputText))));
//var results = eClient.Scroll<Salesreport>("10m", searchResponse.ScrollId);
while (searchResponse.Documents.Any())
{
var res = searchResponse.Documents;
var sds = res.Cast<Sales>();
salesReports.AddRange(sds);
searchResponse = eClient.Scroll<Sales>("10m", searchResponse.ScrollId);
}
}
else
{
// fail log the exception further use
var exception = checkClusterHealth.OriginalException.ToString();
var debugException = checkClusterHealth.DebugInformation.ToString();
}
return salesReports;
}

How do I refactor the code which contains foreach loop

I need to refactor the below code so that the deleted_at logic will be outside of the foreach (var app in data) loop. I tried to create the list guids and then add guids to it but its not working because model.resources is inside the loop and it is still deleting all the apps.
I need deleted_at logic outside because I'm trying to delete all apps which are in the database but are not in new data that I'm receiving from API.
If you have a better approach on my code I would love to see that, Thank you.
public async Task GetBuilds()
{
var data = new List<GetBuildTempClass>();
var guids = new List<GetBuildTempClass>();
using (var scope = _scopeFactory.CreateScope())
{
var _DBcontext = scope.ServiceProvider.GetRequiredService<PCFStatusContexts>();
foreach (var app in data)
{
var request = new HttpRequestMessage(HttpMethod.Get,
"apps/" + app.AppGuid + "/builds?per_page=200&order_by=updated_at");
var response = await _client_SB.SendAsync(request);
var json = await response.Content.ReadAsStringAsync();
BuildsClass.BuildsRootObject model =
JsonConvert.DeserializeObject<BuildsClass.BuildsRootObject>(json);
foreach (var item in model.resources)
{
var x = _DBcontext.Builds.FirstOrDefault(o =>
o.Guid == Guid.Parse(item.guid));
if (x == null)
{
_DBcontext.Builds.Add(new Builds
{
Guid = Guid.Parse(item.guid),
State = item.state,
CreatedAt = item.created_at,
UpdatedAt = item.updated_at,
Error = item.error,
CreatedByGuid = Guid.Parse(item.created_by.guid),
CreatedByName = item.created_by.name,
CreatedByEmail = item.created_by.email,
AppGuid = app.AppGuid,
AppName = app.AppName,
Foundation = 2,
Timestamp = DateTime.Now
});
}
else if (x.UpdatedAt != item.updated_at)
{
x.State = item.state;
x.UpdatedAt = item.updated_at;
x.Timestamp = DateTime.Now;
}
var sqlresult = new GetBuildTempClass
{
AppGuid = Guid.Parse(item.guid)
};
guids.Add(sqlresult);
}
//var guids = model.resources.Select(r => Guid.Parse(r.guid));
var builds = _DBcontext.Builds.Where(o =>
guids.Contains(o.Guid) == false &&
o.Foundation == 2 && o.DeletedAt == null);
foreach (var build_item in builds)
{
build_item.DeletedAt = DateTime.Now;
}
}
await _DBcontext.SaveChangesAsync();
}
}

I got it working I added var guids = new List < Guid > (); list to store data,
added guids.Add(Guid.Parse(item.guid)); to populate the list and finally wrote var builds = _DBcontext.Builds.Where(o = >guids.Contains(o.Guid) == false && o.Foundation == 2 && o.DeletedAt == null); outside the loop.
If anyone has a better suggestion please add a new answer.

How to fetch the data from SqLite database

I have created database in SqLite in my windows app, now I want to fetch the data from my database. This is the code how I inserted the data in databse.
var dbpath = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, "scrapbook.sqlite");
using (var db = new SQLite.SQLiteConnection(dbpath))
{
// Create the tables if they don't exist
var bg = listAlbumContainer[0] as AlbumContainer;
var albumbg = bg.BackgroundImageName;
var sk = listAlbumContainer[0].listAlbumContainer;
var _audio = listAlbumContainer[0].listAlbumContainer5;
var _video = listAlbumContainer[0].listAlbumContainer3;
var wa = listAlbumContainer[0].listAlbumContainer4;
var ci = listAlbumContainer[0].listAlbumContainer2;
var gi = listAlbumContainer[0].listAlbumContainer1;
string snodesticker = Serializeanddeserializwhelper.Serialize(sk);
string nodegi = Serializeanddeserializwhelper.Serialize(gi);
string nodeci = Serializeanddeserializwhelper.Serialize(ci);
string nodewa = Serializeanddeserializwhelper.Serialize(wa);
string nodevideo = Serializeanddeserializwhelper.Serialize(_video);
string nodeaudio = Serializeanddeserializwhelper.Serialize(_audio);
var TittledataInsertCheck = db.Table<Title>().Where(x => x.ALBUM_TITLE.Contains(nametxt.Text)).FirstOrDefault();
if (TittledataInsertCheck == null)
{
db.Insert(new Title()
{
ALBUM_TITLE = nametxt.Text
});
var TittledataInsert = db.Table<Title>().Where(x => x.ALBUM_TITLE.Contains(nametxt.Text)).FirstOrDefault();
if (TittledataInsert != null)
{
db.Insert(new PAGE()
{
PAGE_BACKGROUND = albumbg,
TITLE_ID = TittledataInsert.ID
});
}
}
else
{
await new MessageDialog("Tittle Already Found Please change tittle").ShowAsync();
return;
}
var PagedataInsert = db.Table<PAGE>().Where(x => x.PAGE_BACKGROUND.Contains(albumbg)).FirstOrDefault();
if (PagedataInsert != null)
{
db.Insert(new CONTENT
{
PAGE_ID = PagedataInsert.ID,
STICKERS = snodesticker,
AUDIO = nodeaudio,
VIDEO = nodevideo,
GALLERY_IMAGES = nodegi,
CAMERA_IMAGES = nodeci,
WOARD_ART = nodewa
});
}
db.Commit();
db.Dispose();
db.Close();
var line = new MessageDialog("Records Inserted");
await line.ShowAsync();
}
Is this the right way to insert the data?
I have a canvas on which I set the background image. And on this background some images, video and audio.

Code to Insert Image into SQL Server

I want to insert an image into the SQL Server database from my Windows Forms application.
This question looks like it was trying to ask what I wanted to find out, but it was closed:
Insert image into SQL Server

Here is the code I used to do that.
Modify this code as needed for the table that you are going to use by viewing the design of your database in Microsoft Management Studio:
public static void InsertImage(int inventoryID, int businessID, FileInfo file, string sqlConnection)
{
var list = new List<byte>();
using (var stream = file.Open(FileMode.Open))
{
var data = new byte[stream.Length];
stream.Read(data, 0, data.Length);
list.AddRange(data);
}
var bmp = System.Drawing.Image.FromFile(file.FullName, true);
using (var conn = new SqlConnection(sqlConnection))
{
conn.Open();
var imageId = -1;
var sqlSelect = "SELECT [ImageId] FROM [dbo].[ImageTable] WHERE [InventoryId]=#InventoryId;";
using (var cmd = new SqlCommand(sqlSelect, conn))
{
cmd.Parameters.Add("#InventoryId", System.Data.SqlDbType.Int).Value = inventoryID;
using (var r = cmd.ExecuteReader())
{
if (r.Read())
{
var o = r["ImageId"];
if ((o != null) && (o != DBNull.Value))
{
imageId = (int)o;
}
}
}
}
if (imageId == -1)
{
var sqlCmd = "INSERT INTO [dbo].[ImageTable] " +
"([InventoryId], [ImageFileName], [ImageSize], [ImageWidth], [ImageHeight], [ImageBytes]) " +
"VALUES " +
"(#InventoryId, #ImageFileName, #ImageSize, #ImageWidth, #ImageHeight, #ImageBytes); ";
using (var cmd = new SqlCommand(sqlCmd, conn))
{
cmd.Parameters.Add("#InventoryId", System.Data.SqlDbType.Int).Value = inventoryID;
cmd.Parameters.Add("#ImageFileName", System.Data.SqlDbType.VarChar, 255).Value = file.Name;
cmd.Parameters.Add("#ImageSize", System.Data.SqlDbType.Int).Value = list.Count;
cmd.Parameters.Add("#ImageWidth", System.Data.SqlDbType.SmallInt).Value = bmp.Width;
cmd.Parameters.Add("#ImageHeight", System.Data.SqlDbType.SmallInt).Value = bmp.Height;
cmd.Parameters.Add("#ImageBytes", System.Data.SqlDbType.VarBinary, -1).Value = list.ToArray();
cmd.ExecuteNonQuery();
}
}
}
}
To run/test the code, I created this helper method:
public static string[] GetImages(string fullFolderPath, string searchPattern)
{
var list = new List<String>();
if (Directory.Exists(fullFolderPath))
{
if (String.IsNullOrEmpty(searchPattern))
{
searchPattern = "*.jpg";
}
var dir = new DirectoryInfo(fullFolderPath);
var files = dir.GetFiles(searchPattern);
for (int i = 0; i < files.Length; i++)
{
InsertImage(i + 1, 1, files[i], _sqlConnection);
list.Add(files[i].FullName);
}
}
return list.ToArray();
}
Now, running it from my Console Application is a simple, single call:
static void Main(string[] args)
{
var list = GetImages(#"C:\inetpub\wwwroot\Ads", "*.jpg");
}
