Object doesnot match SQL query results - EF Core 5 - entity-framework-core

Question

I have a DBContext where PriceListTest object is loaded as follows
DBContext.cs:
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
//other code removed
//pricelist
modelBuilder.Entity<PriceListTest>().ToTable(null);
modelBuilder.Entity<PriceListTest>().ToSqlQuery(
#"SELECT T.ID, T.SHORTNAME, T.DESCRIPTION, CTL.CoCTestCode AS CODE, CTL.CoCTestName AS NAME, CTL.CLIENTID, T.ISSET, 0 AS PRICELISTID, CONT.MATRIXTYPEID AS MatrixTypeId, -1 AS MATRIXID
FROM [TESTLIST] T
INNER JOIN [COCTESTLIST] CTL ON ELVISTESTLISTID = T.ID
INNER JOIN CUSTOMERCONTAINERS_TESTLIST custTest on custTest.TESTLISTID = T.ID
INNER JOIN CUSTOMERCONTAINERS cont on cont.id = custTest.CustomerContainerID
WHERE T.RECORDSTATUS = 0");
}
In this code, MatrixTypeId field is the problem!
When I run this query in SQL it will return the following result:
ID
ClientID
MatrixTypeId
7893
NULL
1
7893
NULL
2
7893
NULL
2
7891
NULL
1
7891
735
1
7891
NULL
2
and so on.. (total of 28 records)
In my repository, I filter it based on some parameters.
TestListRepository:
public async Task<List<PriceListTest>> Search(string text,int clientId, int batchId)
{
// some code removed for brevity
var productQuery = await context.PriceListTests.Where(p => !existingTestIds.Contains(p.Id) && (p.Name.Contains(text) || p.Code.Contains(text))
&& (p.ClientId == newClientId)
&& sampleMatrixTypes.Contains(p.MatrixTypeId)).Distinct().ToListAsync();
// productQuery.ToQueryString();
return productQuery;
}
The query that I grab from productQuery.ToQueryString(); is:
DECLARE #__text_1 nvarchar(4000) = N'BTEX';
SELECT DISTINCT [p].[Id], [p].[ClientId], [p].[Code], [p].[Description], [p].[Isset], [p].[MatrixId], [p].[MatrixTypeId], [p].[Name], [p].[PRICELISTID], [p].[ShortName]
FROM
(SELECT T.ID, T.SHORTNAME, T.DESCRIPTION, CTL.CoCTestCode AS CODE, CTL.CoCTestName AS NAME, CTL.CLIENTID, T.ISSET, 0 AS PRICELISTID, CONT.MATRIXTYPEID AS MatrixTypeId, -1 AS MATRIXID
FROM [TESTLIST] T
INNER JOIN [COCTESTLIST] CTL ON ELVISTESTLISTID = T.ID
INNER JOIN CUSTOMERCONTAINERS_TESTLIST custTest ON custTest.TESTLISTID = T.ID
INNER JOIN CUSTOMERCONTAINERS cont on cont.id = custTest.CustomerContainerID
WHERE T.RECORDSTATUS = 0) AS [p]
WHERE (([p].[Id] NOT IN (CAST(5233 AS smallint), CAST(5234 AS smallint), CAST(5766 AS smallint)) AND (((#__text_1 LIKE N'') OR (CHARINDEX(#__text_1, [p].[Name]) > 0)) OR ((#__text_1 LIKE N'') OR (CHARINDEX(#__text_1, [p].[Code]) > 0)))) AND [p].[ClientId] IS NULL) AND [p].[MatrixTypeId] IN (1, 2)
When I run this query, again I get the expected/correct resultset in SQL
ID
ClientID
MatrixTypeId
7893
NULL
1
7893
NULL
2
7891
NULL
1
7891
NULL
2
But when I get the json response, it has all 4 matrixtypeid values fixed as 1
Also, watching the object in debugger has all 4 matrixtypeId are set as 1
ID
ClientID
MatrixTypeId
7893
NULL
1
7893
NULL
1
7891
NULL

7891

PriceListTest.cs
public class PriceListTest
{
public short Id { get; set; }
public string Code { get; set; }
public string ShortName { get; set; }
public string Name { get; set; }
public string Description { get; set; }
public int? ClientId { get; set; }
public bool Isset { get; set; }
public int PRICELISTID { get; set; }
public int MatrixTypeId { get; set; }
public int MatrixId { get; set; }
}
P.S: Other fields like ShortName,Description, Code, Name are all based off on ID so they are repeated as often as ID is being in the above sample.
Also, PriceListID and MatrixId are fixed for backward compatibility but are irrelevant for my code.
UPDATE: I have created a new join table to avoid nesting of so many objects. The new query is:
SELECT distinct T.ID, T.SHORTNAME, T.DESCRIPTION, CTL.CoCTestCode, CTL.CoCTestName, CTL.CLIENTID, T.ISSET, CTLM.MATRIXTYPEID
FROM [TESTLIST] T
INNER JOIN [COCTESTLIST] CTL ON ELVISTESTLISTID = T.ID
INNER JOIN [CoCTestList_MATRIXTYPE] CTLM ON ctl.ID = CTLM.COCTESTLISTID
WHERE T.RECORDSTATUS = 0
Instead of PriceListTest I am now using CoCTestList class/table which is more relevant and straight forward. Also, I have removed the hard coded fields: MatrixID and PriceListID.
The resulting json though still is giving MatrixTypeId as 1 :)
