Executing SELECT Statement With Date In WHERE Clause Fails
Sep 10, 2010
I'm building a dynamic query in my ASP.NET MVC project by the following: [code]Where basically the strWhere is a string that I build up a dynamic filter depending on what the user selects to search on.This works great until I need to add a date comparison to the date clause.[code]Which will end up as:"SELECT VALUE userInfos FROM MyDBEntities.UserInformations AS userInfos Where userInfos.BirthDate <= 10/09/1992"..But when i try to execute the query with the ToList whenever a date is in the where string i get the following error:The argument types 'Edm.DateTime' and 'Edm.Int32' are incompatible for this operation. Near WHERE predicate, line 1, column 103.
I'm using a select statement to select data from an Access DB but I'm using. I can select the data perfectly but when I use the Where clause it doesn't select any data and the data I'm looking is in the DB.
I design a database in datbase.mdb which have a table name Fuel.The primary key Column Name is ID which data type is AutoNumber (Long Integer)User select the ID number and i run he following statement but error occurEID= combo1.text.trim()userid= Convert.ToInt64(EID)Strsql= Select a1,a2 from Fuel where ID= 'userID'ERROR is Creteria DATA TYPE MISMATCH or No record foundPlease
I design a database in datbase.mdb which have a table name Fuel.The primary key Column Name is ID which data type is AutoNumber (Long Integer)User select the ID number and i run the following statement but error occur
EID= combo1.text.trim() userid= Convert.ToInt64(EID) Strsql= Select a1,a2 from Fuel where ID= 'userID'
ERROR is Creteria DATA TYPE MISMATCH or No record found?how i pass the where clause creteria if number datatype?and In accesss i read AutoNumber is Long Integer i also convert into INT64 but error is still there.
I have a month and a year dropdownlist which give me the following string 01/2012 The date format in my db is "2012-01-01 00:00:00" but when I select an individual date and put it in a message box it converts to "01/01/2012"
I've altered my select statement below to reflect the converted date. However Im still not given the correct details. Any ideas? Is there a particular format that I need to use when dealing with a timestamp field? Can I even use the "Right" function in a select statement?
Dim newRecordDate As String = val1 & "/" & ComboBox2.SelectedValue Dim sql2 As String = "Select CatA, CatB, CatC, Cost, Currency, MarketingCode, Comment, RecordDate from vw_tblP_Usage_Details where puid = '" & puid & "' right(RecordDate, 7) = '" & newRecordDate & "'"
Dim executeB As Boolean Select Case myVariable Case "a" 'some code Case "b" 'some code Case Else End Select
If myVariable is "a", control will go into the first case statement. Now let's say if myVariable = "a", but inside a's case block, I find that executeB is true, is it then possible to jump to the second case?
I am trying to read data from an excel sheet but there is an exception saying that no value given for one or more required parameters which I don't understand. Here is my code upto where the error is pointing to:
Dim MyConnection As System.Data.OleDb.OleDbConnection Dim DtSet As System.Data.DataSet Dim MyCommand As System.Data.OleDb.OleDbDataAdapter
[code]....
The exception points to that last line MyCommand.Fill(DtSet) which shows me that there is a problem with my select statement. Previously my code reads the data and displays it without the where clause in the select but when I added the where statement so that it can only read data from rows where the column I has a value equal to 176, it instead gives an exception that shows that some required parameter is missing a value?

i want to use a if, then statement in a where clause in linq to sql. Is this possible? I'm trying to achieve the following:
[Code]...
I'm trying to only add the And If if intLink_pk > -1. If it = -1, then i don't want the and clause at all. Is this posssible within the linq to sql itself?I understand i can write 2 entirely different selects, but if I can't get this done, I may have to write about 50 of them as I want to use multiple Ands if certain conditions are met on the form, such as chk boxes etc.
In my datagrid my sql statement uses a have clause to get set information and i am having countless errors
My code is as shown below, were am i going wrong
con.Open() cmd.Connection = con Dim da As New SqlDataAdapter("SELECT MONTH(Head.SalesDate) AS Month, Detail.ProductID, Detail.Qty, SUM (Detail.Qty) AS TotalSold, SUM(Detail.Qty / 30) AS Average FROM Head INNER JOIN
In the TableAdapter configuration wizard I am using this query:
Code:
SELECT AttendanceID, StudentID, ClassId, DateOfClass, Absent FROM Attendance WHERE (DateOfClass BETWEEN #5/1/2010# AND #5/30/2010#)
Can tell me the correct syntax to change the #5/1/2010# AND #5/30/2010# so the WHERE clause uses dteStartDate AND dteStartDate which are date variables ?
I tried this but it tells me I need to use the to_date function. dteStartDate is already a date variable so I know my syntax is wrong.
Code:
SELECT AttendanceID, StudentID, ClassId, DateOfClass, Absent FROM Attendance WHERE (DateOfClass BETWEEN #" & dteStartDate & "# AND #" & dteEndDate & "#)
i'm doing a desktop application using VS2005 with MSSQL 2005. i have a problem with the where clause in the update statement while selecting the listbox item. this is the code for the listbox in load page:

I have two DataTables, PersonInformationDataTable on which i only know about a "CityName" field, and another CityInformationDataTable, which has a few constant fields and i do a query like
ResultOfQuery = From person As DataRow in PersonInformationDataTable From CityInfo As DataRow in CityInformationDataTable Where (person("CityName) = CityInfo("CityName")) Select ?? all person info ?? , Country = CityInfo("Country"), Tongue = CityInfo("SpokenTongue")
I would like again all the person fields with their values in the enumerable result.
the result would be like : name=. I don't know how many fields or the fields name of PersonInformationDataTable in advance. With a SQL Query, i could write a string with a loop on CityInformationDataTable columns and have a custom select string like : "Select Name,
I am needing a way that an if statement stored inside of an array can be executed.I am designing an application that will allow users to input if statements that will be used to determine if certain values are met. The input is saved to an array that I need to be executed later. Is this possible in Visual Basic?
i have app that connects to a mysql db.i get data from the db with executereader.but i want to execute some sql depending on the result from a other db.but i get a error when doing ExecuteNonQuery() when the reader is still open.Here's a part of my code where the problem occures.
Code: tracecom.CommandText = "select * from testsms left join customer on customer.id=testsms.id where date_sub(now(),interval 1 minute) > testsend" tracerd = tracecom.ExecuteReader() If tracerd.HasRows Then
Dim groupedData = (From p In pData _ Group By p.TruncParam Into Group) _ .SelectMany(Function(g) g.Group) _ .Select(Function(d, idx) New With { _
[Code]...
When the TruncParam changes, I would like the index (idx) in the Select clause to reset to 1. So, in the list above, the Index should be SOLUB0001, SOLUB0002, INSOL0001, INSOL0002...CLRES0001, SUMCA0001, SUME0001.
I am using VS2010 windows application , SQL server 2008 express at backend.I am designing a windows form with fields to search records in database.Say there are 3 fields in the form :
1) material no 2) material group 3)creation date the corressponding table in database with above fields is " Material_master" User can search materials in the database by entering any of the above fields.No I want to write a query where if user doesn't enter anything then my query should work like
"select * from materialmaster "
if only material no is enterd at screen then
"select * from materialmaster where MatNo = materialno "
if both date of creation and material no enterd then
" select * from materialmaster where MatNo = materialno and Date = creationdate "
In other words , field with no values in it should not be accounted in the where clause. Only one query I want to write.How we can achieve this in VB.net windows application?

For some reason i can't select text with the mouse in my application.Also my clients experience the same behaviour.I know it was possible to select a part of the textbox and it stayd selected. Now the selection dissappears and the cursor moves to the front.Only a doubleclick functions properly but selects a single word only.
