I'm trying to run a query from a search form by date and I'm receiving the following error:[Teradata Database] Partial string matching requires character operands.The code for the search is:
ElseIf OptDate.Checked = True Then
sSQL &= "DATE_SUBMIT Like ('" & txtDateRec1.Text & "%')"
End If
i use a database in access and I use a query for adaptor and dataset.
The query is next:
Select * from table1, table2 where table1.idsomething=table2.id and table2.name= 'Name1' AND datebirth>=#07.25.1988# AND datebirth<=#07.31.1988# order by datebirth asc
The error is: Syntax error in date in query expression
In the database the format date is dd-mm-yy.Why I have this problem? What is wrong at the query?
I am trying to bind an Access database to a MSChart control in VB Net 2008. I have a test database populated with four fields SAMPLE-DateTime, Values-Number, MAX-Number and MIN-Number. I'd like to only display the rows that fall within a specific date range but I'm running into a problem when i try to execute the following command:
cmd = "SELECT SAMPLE,VALUES,MAX,MIN FROM TABLE1 WHERE [CHECK_DATE] BETWEEN 01/01/2009 AND 01/01/2011"
[code] when i try to add date into db >> is showing me that error ( Syntax error (missing operator) in query expression '10/07/2011 07:45: )

My approach is to setup three different queries and save to three different variables and then save the data in the three variables into the new table. I have the new table setup in ms access.As you can see from my code, I had tried many different ways to generate my sql statement but none of them works. Now I am trying to figure out which part of the sql statement goes wrong by testing one by one. The two that is uncomment:
1)Dim SDFH As String = "SELECT SegmentCode FROM SegmentPlantTable WHERE DatePlanted < cdate('" & Date.Today & "')"

I have the follow Linq query that is in a web application that was converted from .NET 1.1 to 3.5:
dim objListOfFilteredDataRows = from datarows as datarow in objDataSet.tables(0).rows _
where datarows("SomeColumn") = SomeValue
I have the exact same query in an application that was created using .NET 3.5 and the query returns an IEnumerable. However the query in the converted application is returning:
{Name = "WhereEnumerableIterator`1" FullName = "System.Linq.Enumerable+WhereEnumerableIterator`1[[System.Data.DataRow, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]"}
**Edit: When I highlight the expression, the intellisense says that it doesn't know the type of objListOfFilteredDataRows and assumes its a type of "Object". Why is the type not infered in the converted 1.1 application but is infered in the "native" 3.5?**
What am I missing here? How do I convert the "WhereEnumeratorIterator`1 to an IEnumerable?
I have a query using LINQ-to-SQL. It queries an underlying database table Rooms. It uses Where conditions to narrow down the results, namely:

View 1 RepliesI am developing an application that based on when a user has last entered a payroll, my program tells them the next available Sunday that is available to them based on
1. The date that the last time payroll was entered
2. If payroll ran = "yes" or "no"
I have a sql query that returns the next Sunday back to me based on this criteria, but when I put it into my application, it returns 1/1/0001 to me.
Here is the query:
select MAX(payrolldate) AS [payrolldate],
dateadd(dd, ((datediff(dd, '17530107', MAX(payrolldate))/7)*7)+7, '17530107') AS [Sunday]

Code:"select payrolldate from payroll where(payrolldate <= getdate())and payrollran <> 'yes'")but when I add that query it just returns a value of 1/1/000 as the date.
I have a view on some data in my database it returns the data as I would expect, for example
Call Date To From Phone Number
20/1/2010 00:00 23:59 08923233223
20/1/2010 00:00 23:59 08923233245
However when I have added this to my Entity Model and query it I get duplicate(and unexpected) data appearing
Call Date To From Phone Number
20/1/2010 00:00 23:59 08923233223
20/1/2010 00:00 23:59 08923233223
I am simply binding a Entity Data Source to this Entity but I am left scratching my head as to why the data is being returned differently
EDIT: Interestingly this can't be the result of some strange under the hood join as the row counts match as expected.

Im currently working on an n-layer application that does alot of database work.90% of all database queries are updates, and inserts and I want to be able to view the results of my query in the presentation layer.I was thinking of creating a QueryResult class that has a few properties like QuerySuccessful (boolean), Message (string) - holds success or error message, and optional field to hold any additional data that may need to be passed back to the presentation layer.So I guess my question is, am I going about this the correct way by creating a QueryResult class, and passing that back up through the layers to my PL?

I need to return the exact difference between two dates in the form of a string. If the dates are 01-FEB-2012 and 01-FEB-2014, the function should return "2 years" If the dates are 01-FEB-2012 and 01-MAR-2014, the function should return "25 months". If the difference is not in exact years or months, it should return the difference in days. I do not want to use DateDiff from the Visual Basic namespace so the code is portable to C#.
