Sql - Where Clause In Select Statement - Datetime?
Jan 24, 2012
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 & "'"
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.

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.
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'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 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?
Dim d as Date = DateSerial(Year(rptDate), Month(rptDate), 1 - 1) Dim conn as OleDbConnection = new OleDbConnection(connStr) Dim cm as OleDbCommand = new OleDbCommand()
[code]....
I know that d is the same date as the one in SQL server, specifically 3/31/2011 12:00:00 AM.
Below query works fine for me until I apply Where condition for Hour with attribute Id = '06/02/2009 12:00CDT'. I need to get the max temp for today's date only, and I am not able to use the Where condition in the date field.
"INSERT INTO Images (PicName) VALUES (" & TextBox1.Text & ") WHERE ImageID = " & Summary..if i run the statement without the WHERE clause it works fine, with it i get the error ' Missing ; at end of SQL statement'
I've got a query which returns all invoices and credit notes for a given client, in a loyalty structure query where I need the total value of the points the client achieved through invoices, minus those that was forfeited by credit notes. Now I start my query like this (There are more unions in the query, this is just the first part)
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
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:
[Code]....
and this is my update query in the delete button event handler: mySQL = "update Appointment set recordStatus = 'deleted'" how do i put in the where clause in when i have 4 columns in the listbox? so can i do this with listbox or have to do with datagridview?
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,
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?
I have a LINQ to sql statement that joins 2 tables. I would like to add a order by clause on one of the columns. However the order by clause does not seem to take effect at all. right syntax in VB.net to achieve order by in the following:
Dim query = From dtIt In dbsomecontext.mytable Join dtIl In dbsomecontext.anothertable On dtIt.ItemID Equals dtIl.ItemID Where dtIl.IsAvailable = True Order By dtIt.manufacturer
how to select only records from Excel that meet a certain criteria? For example, this works:
Dim daExcelData As New OleDbDataAdapter Dim cnExcelData As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & txtInputFileAcc.Text & ";Extended Properties=Excel 8.0;") cnExcelData.Open()
I want to put it (the select count statement) in this LINQ statement so I can get the sales count in my linq statement: Dim TheLeads = (From L In DB.Leads Where L.IsDeleted = False Select L).ToList() Is this possible to do in LINQ?
I am using VB.net 2003 application program. I am trying to do a select statement whereby I'm searching between 2 datetime values that are being stored as datetime. records are stored inside Access. For example, I am searching between 2 datetime:
StartTime = 2/23/2009 9:00:00 AM EndTime = 2/23/2009 11:30:00 AM
So I need to find all the records in between 9:00 AM and 11:30 AM on 2/23/2009.
strSQL = "select OrderID from Orders Where OrderDate >= ('" & StartTime & "') AND OrderDate <= ('" & EndTime & "') "
but i got the error showing below:
An unhandled exception of type 'System.Data.OleDb.OleDBException' occurred in system.data.dll
strSQL = "select OrderID from Orders Where OrderDate >= DATEVALUE('" & StartTime & "') AND OrderDate <= DATEVALUE('" & EndTime & "') "
But when I use DATEVALUE, it takes the date from the string and set time as midnight (00:00:00). So it returns no records between 9:00 AM and 11:30 AM on 2/23/2009, but I can see there are records. [Code]
strSQL = "select OrderID from Orders Where OrderDate >= TimeValue('" & StartTime & "') AND OrderDate <= TimeValue('" & EndTime & "') "
And when I use TimeValue, it returns the time from the string and set date as jan 1st. so it returns no records between 9:00 AM and 11:30 AM on 2/23/2009, but I can see there are records. [Code]
but none of the codes above is returning records between 9:00 AM and 11:30 AM on 2/23/2009, but I can see there are records. i searched and found all those examples. but that didn't work. Is there anyway i can search between 2 datetime values. i need to find all the records that lies between that time period (for example: between 9:00 AM and 11:30 AM on 2/23/2009).
I have the properties. I have the format property set to TIME. The text box on the form now shows the time. But when you click on the pull down, you get the date picker.
I have a table which contains a list of products for a company. They input data about how much stock they have and also the level at which they want to be reminded that they need to order new stock.
[Code]...
I want to list all the true results in a form which the user is then able to navigate through. What would be the best way to go about doing this?
with the following code which gets stucked on the line of reader = Cmd.ExecuteReader(). It says the SqlException was unhandled (An expression of non-boolean type specified in a context where a condition is expected, near '7/2/2010'.)
I have successfuly connected to a database and have create a select statement (with access) which works most of the time except when im trying to perform a where statement with a date:
strEmployeeDepartmentLocation = Application.StartupPath con.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source = " & strEmployeeDepartmentLocation & "swineFlu.mdb" strSQLSelectQuery2 = "SELECT NumberOfCase FROM table1 WHERE Date = 21/04/2009;"
i dont no if im writing it in the wrong format or what but it dont seem to bring back any data
I have a datatable and I would like to get the MAX number from this table where Term Number (first Column) is a certain value. If my datatable is declared as dtMyTable, I'm assuming I need to use dtMyTable.Select(), but I'm not sure if this is the best way.
