Asp.net - Complex Linq Query - Add A .Where() Or .Any() Predicate To Reduce Query Complexity (in VB)?
Sep 14, 2010I have to join two main tables, and I need to filter the results by elements in an ASP.NET web form. These filters are created on the fly so I have to use a lot of where extensions to filter the query. I want to execute the query with as optimized SQL as possible.
I am first doing a simple join between TW_Sites and TW_Investigators. Then there are two sub-tables that are involved. TW_InvestigatorToArea and TW_InvestigatorToDisease. While most of the where clauses are working fine, I have found a performance issue that won't be an issue right now, but will be an issue as the table gets bigger.
The arrays DiseaseCategories and DiseaseAreas would be the results of a CheckBoxList result.

Now what's the matter is .. I want a SQL Query which can go under and under.. like 'John Doe' having two members under him named 'Suzan' and 'Ellie' and 'Suzan' is also having 2 members under her.. and same for Ellie. and for example.. 'John Doe' having about 300 members in his down line? All members are making transactions.. like they purchase product and Invoices are being generated (invoices tables have 'memberID'). Now the query is how to generate query which can calculate John Doe's Downline's TurnOver from invoices table's 'totalAmount' field's SUM?

Parameterized Query : Works With Execute Query But Not In Code?
Oct 22, 2009I have created a parameterized query in my tableadapter. Here is the SQL:
SELECT CalcinerID, Comments, CorrectiveActions, CrucibleOxideWt, CrucibleWeight, DCPressure, DCTemperature,
Date, DischargePressure, FeedPressure, FiredCrucibleOxideWt, GmSampleWt, LIMSNumber, LotNumber, MaterialType,
OperatorID, QualLabOperator, QualLabTimeStamp, RecordID, ToteBinNumber [code]....
When I use the Execute Query button in the Tableadapter Query Builder, the query works fine; I get all the rows I expect. However, when I run this in my code, the query behaves like an equality statement (i.e. Lotnumber = @Lotnumber) rather than a LIKE statement (Lotnumber LIKE '%' + @Lotnumber + '%').Here is the code that is not behaving correctly. Note that I have a textbox, LotSearchTextbox, where I enter the portion of the Lotnumber that I want to use as the filter. I also have a button, LotSearchButton:
Private Sub LotSearchButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LotSearchButton.Click
Try
Dim SomeNumber As Integer = Me.LotCalcinerO2TableAdapter.FillByLotNumber(Me.CalcinerDBDataSet.LotCalcinerO2,[code].....
