.NET SQL Date Is Changed Format In Query?

Apr 6, 2010

I've got a date variable that looks like this:

Dim LogDate As Date = Date.Today.AddDays(-1)the format comes out like: #4/5/2010#

then it goes into a SQL select query as a WHERE clause. When I debug, the query has changed this to '05/04/2010'. I want it to be in the format '04/05/2010' like it is when declared. Any ideas on how I do this?

tblBackupArchive.BackupDate, tblStatus.Status FROM tblStatus INNER JOIN tblBackupArchive ON
tblStatus.StatusID = tblBackupArchive.StatusID INNER JOIN tblBackup ON tblBackupArchive.BackupID =

Asp.net - Convert SQL (Pseudocode) To Dymanic LINQ Query From List<Custom> Parameters?

Apr 5, 2012

GOAL: Bind nested ListViews to LINQ generated iQueryable of anonymous type. I want to use LINQ because you can use GroupBy and bind the nested ListView to the 'it' keyword.

SETUP: I have groups of sets of conditions. Each set of conditions is stored in the BillingCodes table. Each group of BillingCodes is stored in the BillingGroups table.

I have a custom object that stores the ID, Name, and NumCodes for each BillingGroup that the user has chosen.I have a collection of these objects called GroupsList that has a list of the groups that the user has chosen.

Problem 1: I can iterate through GroupsList and grab all the IDs. How do I translate the SQL 'WHERE ID IN(a string of comma delineated IDs)' for LINQ to SQL? Is that the best way to do that?

Problem 2: Once I have the list of BillingGroups I need to iterate through each group. For each group, I need to iterate through the BillingCodes. For each BillingCode I need to generate a WHERE clause that has all of the conditions in the BillingCode. I propose something like so:

for each BillingGroup in BillingGroups
for each BillingCode in BillingGroup.BillingCodes
where1 = "..."
next
next

Problem 3: Here's the part where I don't have a clue. I need to dynamically create a query in LINQ to SQL. Keep in mind that I don't know how many groups there'll be or how many codes are in each group.

There are 2 tables:

**transactions**
transaction_id
patient_id

LINQ Query Is Enumerated - Turn On Some Kind Of Flag That Alerts Me Each Time A LINQ Query Is Enumerated?

Sep 22, 2009

I know that LINQ queries are deferred and only executed when the query is enumerated, but I'm having trouble figuring out exactly when that happens.Certainly in a For Each loop, the query would be enumerated.What's the rule of thumb to follow? I don't want to accidentally enumerate over my query twice if it's a huge result.

For example, does System.Linq.Enumerable.First enumerate over the whole query? I ask for performance reasons. I want to pass a LINQ result set to an ASP.NET MVC view, and I also want to pass the First element separately. Enumerating over the results twice would be painful.It would be great to turn on some kind of flag that alerts me each time a LINQ query is enumerated. That way I could catch scenarios when I accidentally enumerate twice.

Asp.net - Complex Linq Query - Add A .Where() Or .Any() Predicate To Reduce Query Complexity (in VB)?

Sep 14, 2010

I 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.

Convert Excel Date To Sql Server Date Time Format Using ACE Provider?

Jun 24, 2011

I am attempting to import data in a batch from an Excel Worksheet to a Sql Server database. Everything works except for the one date field in the spreadsheet. The date returned is off by four years from the value in the spreadsheet. Example: The Excel sheet has a date 10/24/2010 14:18, but when I look at the column in my query, the date is 10/23/2006 2:18. This pattern, 4 years and 1 day earlier, is repeated for every row in the worksheet.

The Excel column comes to me as a custom type, formatted m/d/yyyy h:mm. I receive this from an outside vendor and having them change the column is not going to be my simplest solution.

For what it's worth, the relevent part of the query is:

Select [Date Created] From MyWorksheet
