I'am currently migrating our old system to .Net and I encountered this problem.
I want to return the result but I still need to refine it after the function, but using this code, I don't have a choice but to call the result from the database and filter an in-memory result instead which is poor performance.
public IQueryable<User> GetUser(string[] accessCodes)
{
string condition = "";
if (accessCodes == null)
{
condition = " AccessCode IS NOT NULL "
}
else
{
for (int i = 0; i <= accessCodes.Length - 1; i++)
{
condition += " AccessCode LIKE '%" + accessCodes[i].ToString() + "%' ";
if (i + 1 <= code.Length - 1)
{
condition += " OR ";
}
}
}
return context.ExecuteQuery<User>("SELECT * FROM User WHERE " + condition, null).ToList();
}
I've tried this approach this but i'm stuck:
public IQueryable<User> GetUser(string[] accessCodes)
{
IQueryable<User> basequery = from u in context.User
select u;
if (accessCodes == null)
{
basequery = basequery.Where(n => n.AccessCode != null);
}
else
{
for (int i = 0; i <= accessCodes.Length - 1; i++)
{
// what am I supposed to do here?
}
}
return basequery;
}
I'm hoping that there are solutions which do not require third party libraries.
You can try with Any:
else
{
output = output.Where(u => accessCodes.Any(a => u.AccessCode.Contains(a)));
}
or you can use PredicateBuilder:
if (accessCodes == null)
{
output = output.Where(u => u.AccessCode == null);
}
else
{
var predicate = PredicateBuilder.False<User>();
for (int i = 0; i <= accessCodes.Length - 1; i++)
{
predicate = predicate.Or(u => u.AccessCode.Contains(accessCodes[i]))
}
output = output.Where(predicate);
}
I also changed your if part: Where method does not modify source, it returns new query definition, so you have to assign it back to output to make it work.
This should work for you:
IQueryable<User> basequery = from u in context.User
select u;
if (accessCodes == null)
{
basequery = basequery.Where(u => u.AccessCode != null);
}
else
{
basequery = basequery.Where(u => accessCodes.Contains(u=>u.AccessCode));
}
also make sure you return basequery, since output in your method is not defined and not used.

I have a search query which search for all jobs in the database and than displays them in accordance to the most recent ones filtering the data by date as follows:
result = db.AllJobModel.Where(a => a.JobTitle.Contains(searchTitle) && a.locationName.Contains(searchLocation)).ToList());
result = (from app in result orderby DateTime.ParseExact(app.PostedDate, "dd/MM/yyyy", null) descending select app).ToList();
result = GetAllJobModelsOrder(result);
after that I have a method GetAllJobModelsOrder which displays jobs in order which seems to be work fine but in my case its not ordering jobs so I need to understand where I am wrong:
private List<AllJobModel> GetAllJobModelsOrder(List<AllJobModel> result)
{
var list = result.OrderBy(m => m.JobImage.Contains("job1") ? 1 :
m.JobImage.Contains("job2") ? 2 :
m.JobImage.Contains("job3") ? 3 :
m.JobImage.Contains("job4") ? 4 :
m.JobImage.Contains("job5") ? 5 :
6)
.ToList();
return list;
}
The result I get is about 10 jobs from job1 and than followed by other jobs in the same order what I would like to achieve is to filter the most recent jobs than display one job from each type of a job.
An example of the input would be as follows:
AllJobModel allJobModel = new AllJobModel
{
JobDescription = "Description",
JobImage = "Job1",
JobTitle = "title",
locationName = "UK",
datePosted = "15/06/2020",
}
The output that I get is as follows:
In where result should be mixed from different jobs.
Excepted resulta as follows a specific order of job source--1. TotalJob[0] :: 2. MonsterJob[0] :: 3. Redd[0] :: 4. TotalJob[ 1 ] :: 5. MonsterJob[ 1 ] ::6. Redd[ 1 ]:
I have tried the following solution but list data structure seems to be not stroing data in order:
private List<AllJobModel> GetAllJobModelsOrder(List<AllJobModel> result)
{
string lastItem = "";
List<AllJobModel> list = new List<AllJobModel>();
int pos = -1;
while(result.Count != 0)
{
for(int i = 0; i < result.Count; i++)
{
if(result[i].JobImage.Contains("reed") && (lastItem == "" || lastItem == "total" || lastItem == "monster"))
{
pos++;
list.Insert(pos,result[i]);
lastItem = "reed";
result.Remove(result[i]);
break;
}else if (result[i].JobImage.Contains("total") && (lastItem == "reed" || lastItem == "monster" || lastItem == "" ))
{
pos++;
list.Insert(pos, result[i]);
lastItem = "total";
result.Remove(result[i]);
break;
}else if(result[i].JobImage.Contains("monster.png") && (lastItem =="total" || lastItem == "reed" || lastItem == "" ))
{
pos++;
list.Insert(pos, result[i]);
lastItem = "monster";
result.Remove(result[i]);
break;
}else if(result[i].JobImage.Contains("reed") &&( lastItem == "reed"))
{
if(result.FirstOrDefault(a=>a.JobImage.Contains("total") || a.JobImage.Contains("monster")) != null)
{
lastItem = "total";
break;
}
else
{
pos++;
list.Insert(pos, result[i]);
lastItem = "reed";
result.Remove(result[i]);
break;
}
}
else if (result[i].JobImage.Contains("total") && (lastItem == "total"))
{
if (result.FirstOrDefault(a => a.JobImage.Contains("reed") || a.JobImage.Contains("monster")) != null)
{
lastItem = "monster";
break;
}
else
{
pos++;
list.Insert(pos, result[i]);
lastItem = "total";
result.Remove(result[i]);
break;
}
}
else if (result[i].JobImage.Contains("monster") && (lastItem == "monster"))
{
if (result.FirstOrDefault(a => a.JobImage.Contains("total") || a.JobImage.Contains("reed")) != null)
{
lastItem = "reed";
break;
}
else
{
pos++;
list.Insert(pos, result[i]);
lastItem = "monster";
result.Remove(result[i]);
break;
}
}
}
}
return list;
}
also what I found is that the value of the elements in the list is different from what its actual value. So I am not sure if this is an error with my code or with visual studio:
you can use the below concept here. I am sorting a list based on the numeric value at the end of each string value using Regex.
List<string> ls = new List<string>() { "job2", "job1", "job4", "job3" };
ls = ls.OrderBy(x => Regex.Match(x, #"\d+$").Value).ToList();
Certainly the requirement was not as straight forward as initially thought. Which is why I am offering a second solution.
Having order by and rotate the offering "Firm" in a type of priority list for a set number of times and then just display whatever comes after that requires a custom solution. If the one algorithm you have works and you are happy then great. Otherwise, I have come up with this algorithm.
private static List<AllJobModel> ProcessJobs(List<AllJobModel> l)
{
var noPriorityFirst = 2;
var orderedList = new List<AllJobModel>();
var priorityImage = new string[] { "TotalJob", "MonsterJob", "Redd" };
var gl = l.OrderBy(o => o.datePosted).GroupBy(g => g.datePosted).ToList();
foreach (var g in gl)
{
var key = g.Key;
for (int i = 0; i < noPriorityFirst; i++)
{
foreach (var j in priorityImage)
{
var a = l.Where(w => w.datePosted.Equals(key) && w.JobImage.Equals(j)).FirstOrDefault();
if (a != null)
{
orderedList.Add(a);
var ra = l.Remove(a);
}
}
}
foreach (var j in l.ToList())
{
var a = l.Where(w => w.datePosted.Equals(key)).FirstOrDefault();
if (a != null)
{
orderedList.Add(a);
var ra = l.Remove(a);
}
}
}
return orderedList;
}
To test this process I have created this Console app:
static void Main(string[] args)
{
Console.WriteLine("Start");
var l = CreateTestList();
var lJobs = ProcessJobs(l);
lJobs.ForEach(x => Console.WriteLine($"{x.datePosted} : {x.JobImage}"));
}
private static List<AllJobModel> CreateTestList()
{
var orderedList = new List<AllJobModel>();
var l = new List<AllJobModel>();
var priorityImage = new string[] { "TotalJob", "MonsterJob", "Redd" };
var rand = new Random();
var startTime = DateTime.Now;
for (int i = 0; i < 20; i++)
{
var j = rand.Next(0, priorityImage.Length);
var h = rand.Next(0, 4);
var a = new AllJobModel();
a.JobDescription = "Desc " + i;
a.JobImage = priorityImage[j];
a.JobTitle = "Title" + i;
a.locationName = "UK";
a.datePosted = startTime.AddDays(h);
l.Add(a);
}
for (int i = 0; i < 20; i++)
{
var j = rand.Next(0, priorityImage.Length);
var h = rand.Next(0, 4);
var a = new AllJobModel();
a.JobDescription = "Desc " + i;
a.JobImage = "Job " + i;
a.JobTitle = "Title" + i;
a.locationName = "UK";
a.datePosted = startTime.AddDays(h);
l.Add(a);
}
return l;
}
I'm building a Spec Evaluator which must consider multiple possible OrderBy, as in the next example:
if (spec.Order != null)
{
var count = spec.Order.Count;
if (count == 1)
{
query = query.OrderBy(spec.Order[0]);
}
else if (count == 2)
{
query = query.OrderBy(spec.Order[0])
.ThenBy(spec.Order[1]);
}
else if (count == 3)
{
query = query.OrderBy(spec.Order[0])
.ThenBy(spec.Order[1])
.ThenBy(spec.Order[2]);
}
// And so on...
}
Queryis an IQueryable, spec.Order is a list of clauses: List<Expression<Func<T, object>>>.
I know that I can use an OrderBy with all the clauses passed as string. And I guess I can just project all the Order clauses to a new string comma-separated. But that solution doesn't seem clean.
Is there any other way to dynamically generate one new ThenBy for every item of the Order list, above 1?
You could use a for loop. Basically loop through all of the Order values, use OrderBy for the first one, and ThenBy for subsequent items. Since you've said that you're using IQueryable, I've modified this to use a temporary IOrderedQueryable<T> variable.
if (spec.Order != null)
{
var count = spec.Order.Count;
IOrderedQueryable<T> orderedQuery = null;
for (int i = 0; i < count; ++i)
{
if (i == 0)
{
orderedQuery = query.OrderBy(spec.Order[i]);
}
else
{
orderedQuery = orderedQuery.ThenBy(spec.Order[i]);
}
}
query = orderedQuery ?? query;
}
You could also approach it like this, although I'm not sure how the performance differs between the two methods, if it does at all:
if (spec.Order != null)
{
var count = spec.Order.Count;
for (int i = 0; i < count; ++i)
{
if (query is IOrderedQueryable<T> orderedQuery)
{
query = orderedQuery.ThenBy(spec.Order[i]);
}
else
{
query = query.OrderBy(spec.Order[i]);
}
}
}
I am using Sqlite.Net in my Xamarin.Forms application. So far it has been great at returning lists of objects if my object is a class like so:
SqliteDatabase.Connection.Query<Customer>("Select * from Customers");
I would now like to return the equivalent of a DataSet dynamically from my query
SqliteDatabase.Connection.Query("Select * from Customers inner join Calls on Customers.Id=Calls.CustomerId")
Now from the second query I would like to return a DataSet instead of a list of objects. I know I could create a new object which combines the columns of Customers and Calls but I don't want to have to create objects every time I want to query the database.
Is it possible to just dynamically return a Dataset or Object?
In the end I actually managed to come up with a method that will run any query and return the rows as items in the list and the columns as objects in the array:
public List<object[]> RunSql(string sqlString, bool includeColumnNamesAsFirstRow)
{
var lstRes = new List<object[]>();
SQLitePCL.sqlite3_stmt stQuery = null;
try
{
stQuery = SQLite3.Prepare2(fieldStrikeDatabase.Connection.Handle, sqlString);
var colLenght = SQLite3.ColumnCount(stQuery);
if (includeColumnNamesAsFirstRow)
{
var obj = new object[colLenght];
lstRes.Add(obj);
for (int i = 0; i < colLenght; i++)
{
obj[i] = SQLite3.ColumnName(stQuery, i);
}
}
while (SQLite3.Step(stQuery) == SQLite3.Result.Row)
{
var obj = new object[colLenght];
lstRes.Add(obj);
for (int i = 0; i < colLenght; i++)
{
var columnType = SQLitePCL.raw.sqlite3_column_decltype(stQuery, i);
switch (columnType)
{
case "text":
obj[i] = SQLite3.ColumnString(stQuery, i);
break;
case "int":
obj[i] = SQLite3.ColumnInt(stQuery, i);
break;
case "real":
obj[i] = SQLite3.ColumnDouble(stQuery, i);
break;
case "blob":
obj[i] = SQLite3.ColumnBlob(stQuery, i);
break;
case "null":
obj[i] = null;
break;
}
}
}
return lstRes;
}
catch (Exception)
{
return null;
}
finally
{
if (stQuery != null)
{
SQLite3.Finalize(stQuery);
}
}
}
SQLite.NET PCL is a .NET wrapper around sqlite.
Therefore you can query similar to EF by using a join in in LINQ or Lambda than in the Query. The wrapper will handle the conversion to sqlite query for you.
You can then return a new datatype of the joined type or a dynamic type.
Note : Joins are not directly supported in sqlite (more info) and work around is mentioned here.
Sample code:
var conn = new SQLiteConnection(sqlitePlatform, "foofoo");
var query = from customer in conn.Table<Customers>().ToList()
join call in conn.Table<Calls>().ToList()
on customer.ID equals call.CustomerId
select new { Customer = customer , Calls = call };
Lambda version:
conn.Table<Customer>().ToList().Join
(conn.Table<Call>().ToList(),
customer => customer.Id,
call => call.CustomerId,
(customer, call) => new { Customer = customer, Calls = call });
thank u so much user1! works perfect.
here is just an example how to use ur method:
var objects = mySQLiteConnection.RunSql("SELECT * FROM Persons", true);
// ColumnNames
List<string> ColumnNames = new List<string>();
for (int column = 0; column < objects[0].Length; column++)
{
if (objects[0][column] != null) spaltennamen.Add((string)objects[0][column]);
}
// RowValues
for (int row = 1; row < objects.Count; row++)
{
for (int column = 0; column < objects[row].Length; column++)
{
if (objects[row][column] != null) System.Diagnostics.Debug.WriteLine(spaltennamen[column] + " : " + objects[row][column]);
}
}
It sounds like what you want to do is essentially recreate ADO.NET. When you say "DataSet", I'm guessing that you are talking about ADO.NET. This probably means that you don't want to use the ORM functionality built in to the SQLite.Net library.
I have created this version of the library that will allow you to do flat table reads from an SQLite database. It means that you CAN read the data in to an ADO.NET dataset if you like.

Unlike #Fabian Monkemoller, i was unable to get #User1's code to work straight away. This is a modified version that make use of nullable reference types and method-nesting to seperate the main-code from the try-catch block:
public static object?[][]? ToDataSet(this SQLiteConnection sqlConnection, string query , bool includeColumnNamesAsFirstRow = true)
{
var stQuery = SQLite3.Prepare2(sqlConnection.Handle, query );
var colLength = SQLite3.ColumnCount(stQuery);
try
{
return SelectRows().ToArray();
}
catch (Exception e)
{
return null;
}
finally
{
if (stQuery != null)
{
SQLite3.Finalize(stQuery);
}
}
IEnumerable<object?[]> SelectRows()
{
if (includeColumnNamesAsFirstRow)
{
yield return SelectColumnNames(stQuery, colLength).ToArray();
}
while (SQLite3.Step(stQuery) == SQLite3.Result.Row)
{
yield return SelectColumns(stQuery, colLength).ToArray();
}
static IEnumerable<object> SelectColumnNames(SQLitePCL.sqlite3_stmt stQuery, int colLength)
{
for (int i = 0; i < colLength; i++)
{
yield return SQLite3.ColumnName(stQuery, i);
}
}
static IEnumerable<object?> SelectColumns(SQLitePCL.sqlite3_stmt stQuery, int colLength)
{
for (int i = 0; i < colLength; i++)
{
var x = SQLitePCL.raw.sqlite3_column_decltype(stQuery, i);
yield return x switch
{
"text" => SQLite3.ColumnString(stQuery, i),
"integer" => SQLite3.ColumnInt(stQuery, i),
"bigint" => SQLite3.ColumnInt64(stQuery, i),
"real" => SQLite3.ColumnDouble(stQuery, i),
"blob" => SQLite3.ColumnBlob(stQuery, i),
"null" => null,
_ => throw new Exception($"Unexpected type encountered in for query {stQuery}")
};
}
}
}
}
I know this is a dumb question because you cannot modify the loop collection while in a loop, but I do need to change it. I know I must not change the referenced objects, but I have no idea how to do this.
var orders = _orderService.GetOrders(o => !o.Deleted &&
o.OrderStatus != OrderStatus.Cancelled &&
o.OrderStatus != OrderStatus.Complete);
foreach (var order in orders)
{
if (order.PaymentStatus == PaymentStatus.Paid)
{
if (order.ShippingStatus == ShippingStatus.ShippingNotRequired || order.ShippingStatus == ShippingStatus.Delivered)
{
var tempOrder = _orderService.GetOrderById(order.Id);
SetOrderStatus(tempOrder , OrderStatus.Complete, true);
}
}
}
I always get an error.
UPDATED: I changed to this
var orders = _orderService.GetOrders(o => !o.Deleted &&
o.OrderStatus != OrderStatus.Cancelled && o.OrderStatus != OrderStatus.CompletE);
List<int> orderIndex = new List<int>();
orders.ToList().ForEach(x => orderIndex.Add(x.Id));
foreach(var index in orderIndex)
{
var order = _orderService.GetOrderById(index);
if (order.PaymentStatus == PaymentStatus.Paid)
{
if (order.ShippingStatus == ShippingStatus.ShippingNotRequired || order.ShippingStatus == ShippingStatus.Delivered)
{
SetOrderStatus(order, OrderStatus.Complete, true);
}
}
}
try
int count = orders.Count; // the length of the collect : may need a different method for different collection types.
for(int i = 0; i < count; i++)
{
var current = orders[i];
// do stuff with current.
}
use for loop instead of foreach loop
for(int i=0; i<orders.Count; i++)
{
if (orders[i].PaymentStatus == PaymentStatus.Paid)
{
if (orders[i].ShippingStatus == ShippingStatus.ShippingNotRequired || orders[i].ShippingStatus == ShippingStatus.Delivered)
{
var tempOrder = _orderService.GetOrderById(orders[i].Id);
SetOrderStatus(tempOrder , OrderStatus.Complete, true);
}
}
}
I'm trying to get some records from the Azure Table Storage while using paging with the continuation token.
I have the following code:
public Stories SelectStory(DateTime start, DateTime end, string searchGuid)
{
long startTicks = DateTime.MaxValue.Ticks - start.ToUniversalTime().Ticks;
long endTicks = DateTime.MaxValue.Ticks - end.ToUniversalTime().Ticks;
var stories = _ServiceContext.CreateQuery<Story>("Story").Where(s => Convert.ToInt64(s.RowKey.Substring(0, s.PartitionKey.IndexOf("_"))) > startTicks
&& Convert.ToInt64(s.RowKey.Substring(0, s.PartitionKey.IndexOf("_"))) < endTicks
&& s.RowKey == "story_" + searchGuid).Take(50);
var query = stories as DataServiceQuery<Story>;
var results = query.Execute();
var response = results as QueryOperationResponse;
Stories temp = new Stories();
if(response.Headers.ContainsKey("x-ms-continuation-NextRowKey"))
{
temp.NextPartitionKey = response.Headers["x-ms-continuation-NextPartitionKey"];
if (response.Headers.ContainsKey("x-ms-continuation-NextRowKey"))
{
temp.NextRowKey = response.Headers["x-ms-continuation-NextRowKey"];
}
}
temp.List = results.ToList();
return temp;
}
But I'm getting the following error:
The expression (((ToInt64([10007].RowKey.Substring(0, [10007].PartitionKey.IndexOf("_"))) > 2521167043199999999) And (ToInt64([10007].RowKey.Substring(0, [10007].PartitionKey.IndexOf("_"))) < 2521154083199999999)) And ([10007].RowKey == "story_9")) is not supported.
I'm not sure why the expression is not allowed. Does anyone have any ideas how I can change it to get it to work?
Thanks!
Edit: the new code (no errors but no data gets selected - even though i know it exists):
public Stories SelectStory(DateTime start, DateTime end, string searchGuid)
{
long startTicks = DateTime.MaxValue.Ticks - start.ToUniversalTime().Ticks;
long endTicks = DateTime.MaxValue.Ticks - end.ToUniversalTime().Ticks;
var strStart = string.Format("{0:10}_{1}", DateTime.MaxValue.Ticks - startTicks, "00000000-0000-0000-0000-000000000000");
var strEnd = string.Format("{0:10}_{1}", DateTime.MaxValue.Ticks - endTicks, "00000000-0000-0000-0000-000000000000");
var stories = _ServiceContext.CreateQuery<Story>("Story").Where(
s => s.RowKey.CompareTo(strStart) < 0
&& s.RowKey.CompareTo(strEnd) > 0
//s.RowKey.CompareTo(startTicks.ToString() + "_") > 0
//&& s.RowKey.CompareTo(endTicks.ToString() + "_00000000-0000-0000-0000-000000000000") > 0
&& s.PartitionKey == ("story_" + searchGuid)
).Take(50);
var query = stories as DataServiceQuery<Story>;
var results = query.Execute();
var response = results as QueryOperationResponse;
Stories temp = new Stories();
if(response.Headers.ContainsKey("x-ms-continuation-NextRowKey"))
{
temp.NextPartitionKey = response.Headers["x-ms-continuation-NextPartitionKey"];
if (response.Headers.ContainsKey("x-ms-continuation-NextRowKey"))
{
temp.NextRowKey = response.Headers["x-ms-continuation-NextRowKey"];
}
}
temp.List = results.ToList();
return temp;
}
OK, I think there are a couple of things going on here. One I think there is a logic flaw. Shouldn't
Convert.ToInt64(s.RowKey.Substring(0, s.PartitionKey.IndexOf("_")))
be
Convert.ToInt64(s.PartitionKey.Substring(0, s.PartitionKey.IndexOf("_")))
Secondly you need to be very careful about which functions are supported by azure table queries. Generally they're not. I've tested .Substring() and .IndexOf() and they don't work in Azure Table queries, so the chances of .ToInt64() working is slim to none.
You might be able to reformat this to be
s => s.PartitionKey > startTicks.ToString() + "_"
&& s.PartitionKey < endTicks.ToString() + "_"
&& s.RowKey == "story_" + searchGuid
This will likely not generate a very efficient query because Azure can get confused if you have two filters based on partition key and just do a table scan. Another option is to not include the endTicks part of the query and when you process the results, when you get to one the partition key is greater than end ticks, stop processing the results.
Also your code as you have it written won't get all of the items based on the continuation token, it will just get the first set of results that are returned. I think your final code should look something like this (uncompiled, untested and I'm sure people can see some performance improvements:
private class ListRowsContinuationToken
{
public string NextPartitionKey { get; set; }
public string NextRowKey { get; set; }
}
public Stories SelectStory(DateTime start, DateTime end, string searchGuid)

long endTicks = DateTime.MaxValue.Ticks - end.ToUniversalTime().Ticks;
var stories = _ServiceContext.CreateQuery<Story>("Story").Where(s => s.PartitionKey > startTicks.ToString() + "_"
&& s.PartitionKey < endTicks.ToString() + "_"
&& s.RowKey == "story_" + searchGuid).Take(50);

}
}
var response = (QueryOperationResponse<T>)query.Execute();
foreach (Story result in response)

finalList.AddRange(result);
