Comparing A Real Datetime To A 'constructed' Datetime
Jun 15, 2004
I have the following SQL:
select convert(datetime,'04-20-' + right(term,4)) as dt,
'Deposit' as type, a.* from
dbo.status_view a
where right(term,4) always returns a string which constitutes a 4 digit year eg '1999','2004',etc.
The SQL above returns
2004-04-20 00:00:00.000 Deposit ...
Which makes me think that it is able to successfully construct the datetime object inline. But then when I try and do:
select * from
(
select convert(datetime,'04-20-' + right(term,4)) as dt,
'Deposit' as type, a.* from
dbo.status_view a
) where dt >= a.submit_date
I get the following error:
Syntax error converting datetime from character string.
Given that it executes the innermost SQL just fine and seems to convert the string to a datetime object, I don't see why subsequently trying to USE that datetime object for something (in this case comparison with submit_date which is a datetime in the table a) should screw it up. Help!!! Thanks...
Hi,I would like to convert real data type to datetime type. Example:I have a real data type which is: 23,613456 (23 hours and 0,613456). Iwould like to have it in hh:mm:ss format. How to do this? Can I useconvert/cas function?Thanks for helpRgdsMario
I have a table with a DateTime field that has Dates in the format of mm/dd/yyyy I want to do a simple count on the table for the previous day but keep getting 0 for the results. Here is the script I've been trying.
SELECT COUNT(*) FROM mytbl WHERE Collected_Date = DateAdd (dd, -1, GetDate())
It appears to me that the time portion of the DateAdd function keeps the matches that I am looking for from happening. What am I missing or am I going about this all wrong?
I am trying to return all records between 2 dates. The Date columns are in DateTime format, and i am ignoring the timestamp. The user should be able to input UK Date Format (dd/mm/yyyy) and return the rows. This sql code works fine for American date format, but i get an error: converting from varchar to datetime when i put in a UK format. eg. 22/11/06. Please advise on this problem! many thanks!

sorry folks the other message was on the wrong board!

Hi, I have a varchar field named FinancialYTDCode containing data in the format 2007F or 2008F. I want to only select the rows with the FinancialYTDCode that is the same as the current year.
Could someone please show me how I write this in my script. Thanks
Is there a performance impact (if so, how great is it) when comparing a date to a datetime data type?
An educated guess suggests yes, as there will be a type casting... but then again I don't believe there's an issue when comparing an int to a tinyint and there's an assumption these would play by the same rules?
This has only come about because I'm considering changing the data type used in my standard calendar script and this popped in to my head.
Hi, I'm inserting a datetime values into sql server 2000 from c#
SQL server table details Table nameate_test columnname datatype No int date_t DateTime
C# coding SqlConnection connectionToDatabase = new SqlConnection("Data Source=.\SQLEXPRESS;Initial Catalog=testdb;Integrated Security=SSPI"); connectionToDatabase.Open(); DataTable dt1 = new DataTable(); dt1.Columns.Add("no",typeof(System.Int16)); dt1.Columns.Add("date_t", typeof(System.DateTime)); DataRow dr = dt1.NewRow(); dr["no"] = 1; dr["date_t"] = DateTime.Now; dt1.Rows.Add(dr); for(int i=0;i<dt1.Rows.Count;i++) { string str=dt1.Rows["no"].ToString(); DateTime dt=(DateTime)dt1.Rows["date_t"]; string insertQuery = "insert into date_test values(" + str + ",'" + dt + "')"; SqlCommand cmd = new SqlCommand(insertQuery, connectionToDatabase); cmd.ExecuteNonQuery(); MessageBox.Show("saved"); } When I run the above code, data is inserted into the table The value in the date_t column is 2007-07-09 22:10:11 000.The milliseconds value is always 000 only.I need the millisecond values also in date_t column. Is there any conversion needed for millisecond values?
Hi all, having a little problem with saving dates to sql databaseI've got the CreatedOn field in the table set to datetime type, but every time i try and run it i get an error kicked up Error "The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.The statement has been terminated."I've tried researching it but not been able to find something similar. Heres the code: DateTime createOn = DateTime.Now;string sSQLStatement = "INSERT INTO Index (Name, Description, Creator,CreatedOn) values ('" + name + "','" + description + "','" + userName + "','" + createOn + "')"; Any help would be much appreciated
Hey :)I'm facing a lot of troubles trying to create a new pause/break-system. Right now i'm building up the query that counts how many records that is inside 2 fields. Let me first show you my table: ID (int) | stamp_start (Type: DateTime) | stamp_end (Type: DateTime) | Username (varchar)0 | 17-03-07 12:00:00 | 17-03-07 12:30:00 | Hovgaard The client will enter a start time and a end time and this query should then count how many records that are inside this periode of time. Example: The client enter starttime: 12:05 and endtime: 12:35.The query shall then return 1 record found. The same thing if the user enters 12:20 and 12:50.My current query looks like this:SELECT COUNT(ID) AS Expr1 FROM table WHERE (start_stamp <= @pausetime_start) AND (end_stamp >= @pausetime_end)But this will only count if I enter the exact same times as the one inside the table.Any ideas how I can figure this out?Thanks for your time so far :)/Jonas Hovgaard - Denmark
Hi, I have a column of type datetime in sqlserver 2000. Whenever I try to insert the date '31/08/2006 23:28:59' I get the error "...datetime data type resulted in an out-of-range datetime value" I've looked everywhere and I can't solve the problem. Please note, I first got this error from an asp.net page and in order to ensure that it wasn't some problem with culture settings I decided to run the query straight in Sql Query Anaylser. The results were the same. What else could it be? cheers, Ernest
I am inserting date and time data into a SQL Server 2012 Express table from an application. The application is providing the date and time as a string data type. Is there a TSQL way to convert the date and time string to an SQL datetime date type? I want to do the conversion, because SQL displays an error due to the
My date and time string from the application looks like : 3/11/2014 12:57:57 PM
Nothing difficult, I just need a way to generate a new datetime column based on the column [PostedDate], datetime. So basically I want to truncate the time. Thanks a lot.

hi, How do i convert a varchar field into the datetime data type? the reason i need this lies in the requirement that in the earlier data base the column that is hlding the date value is having the data type as varchar. and in the new design the column data type is datetime. i am using sql scripts for the data migration from the older design to the newer and got stuck with this datetime convertion issue. do let me know the best possible solution.
following are the sample data that is theer in the older table for the date.
12/12/2003 1/13/2007 01132004 1-1-2004 1.2.2001
there is no uniformity of the data that is stored currently.
I have a table that has a unique ID and a datetime of when something changed.
See example: IDÂ Â Â TimeStamp 16094Â Â Â 2013-11-25 11:46:38.357 16095Â Â Â 2013-11-25 11:46:38.430 16096Â Â Â 2013-11-25 11:46:38.713 16097Â Â Â 2013-11-25 11:46:38.717 16098Â Â Â 2013-11-25 11:46:38.780

Hi All,This is only my second day using C#/asp.net and English isn't my native language so I'll apologise in advance if this question doesn't make sense and/or is stupid . I'm trying to make a little event planner which was going well until I hit a small problem, the user needs to enter the event name and choose a date/time from dropdowns, this bit works okay... however I'm having difficulties with storing the date/time, at the moment I'm making a DateTime object and filling out the year/month/day/hour/minute selected on the form and adding that to the database field (which is a datetime field type).Problem is, I'm using the date format DD/MM/YYYY HH:MM:SS but the database stores it as MM/DD/YYYY HH:MM:SS so if I wanted to do things like: select * from tbl where date > DateTime.Now - it isn't going to work because the month is switched with the day in the DB-versions. Just to try and give another example, if I'm not being very clear, if I print DateTime.Now.ToString() it will display 10/06/2008 02:50:48 however if I put it into the database and pull it back out cast to a DateTime Object and then display that object via ToString() it'll be 06/10/2008 02:50:48 Any suggestions on what to do would be appreciated, usually in cases like this I'd just use the unix timestamp, but since C#/ASP.NET doesn't support that natively I was hoping there was an easier/native alternative. Also I don't have access to the server configuration so changing the localization of mssql isn't an option unfortunately.Thanks in advance!

I can do this in an old (~2003) way, but I'm trying to figure out a new (2005) way. What I've got is an e-commerce project in which users select various products from a catalog and add them to a shopping cart. Then they go to a checkout page which displays the current contents of the shopping cart, which are contained in a manually-constructed data table (system.data.datatable). On the checkout page a GridView displays the contents of the data table. At that point they can check out via button click, which launches the following (somewhat simplified) ADO.NET code:1 Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) 2 'Some variables 3 Dim intCounter As Integer 'Used to count the loop 4 Dim prmQuantity As New System.Data.SqlClient.SqlParameter() 'A parameter 5 Dim prmProduct As New System.Data.SqlClient.SqlParameter() 'A parameter 6 Dim prmPrice As New System.Data.SqlClient.SqlParameter() 'A parameter 7 Dim InsertCommand As New System.Data.SqlClient.SqlCommand 'The SQL insert command 8 Dim dbConnection As New System.Data.SqlClient.SqlConnection 'The connection to the DB 9 10 'Set the parameters for the SQL statement 11 prmQuantity.ParameterName = "@Quantity" 12 prmQuantity.SqlDbType = Data.SqlDbType.Int 13 prmQuantity.Size = 18 14 prmQuantity.Direction = Data.ParameterDirection.Input 15 16 prmProduct.ParameterName = "@Product" 17 prmProduct.SqlDbType = Data.SqlDbType.VarChar 18 prmProduct.Size = 50 19 prmProduct.Direction = Data.ParameterDirection.Input 20 21 prmPrice.ParameterName = "@Price" 22 prmPrice.SqlDbType = Data.SqlDbType.Int 23 prmPrice.Size = 18 24 prmPrice.Direction = Data.ParameterDirection.Input 25 26 'Create the connection to the database using web.config 27 dbConnection.ConnectionString = ConfigurationManager.ConnectionStrings("MyDB").ConnectionString 28 29 'Various command settings 30 InsertCommand.CommandText = "INSERT INTO [Orders] ([Quantity], [Product], [OrderDate], [ItemPrice]) VALUES (@Quantity, @Product, {fn NOW()}, @Price)" 31 InsertCommand.CommandType = Data.CommandType.Text 32 InsertCommand.Connection = dbConnection 33 34 'Add the rows to the database 35 For intCounter = 0 To objDT.Rows.Count - 1 36 37 'Re-inserts the data rows from objDT 38 objDR = objDT.Rows(intCounter) 39 40 'Set param values 41 prmQuantity.Value = objDR("Quantity") 42 prmProduct.Value = objDR("Product") 43 prmPrice.Value = objDR("Price") 44 45 'Add params to insert command 46 InsertCommand.Parameters.Add(prmQuantity) 47 InsertCommand.Parameters.Add(prmProduct) 48 InsertCommand.Parameters.Add(prmPrice) 49 50 'Open connection 51 InsertCommand.Connection.Open() 52 53 'Execute the insert command 54 InsertCommand.ExecuteNonQuery() 55 56 'Close connection and clear parameters for the next loop 57 InsertCommand.Connection.Close() 58 InsertCommand.Parameters.Clear() 59 60 Next 61 62 Response.Redirect("done.aspx") 63 64 End Sub 65 What I'd like to do is see if I can instead use a simplified approach based on 2.0 controls. Specifically, I was hoping that I could use an SqlDataSource and simply tap into its built-in Insert capabilities. So I tried this alternate procedure:Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs)Dim intCounter As Integer 'Used to count the loopFor intCounter = 0 To objDT.Rows.Count - 1DSOrdersNew.InsertParameters("Product") = objDR("Product")DSOrdersNew.InsertParameters("Quantity") = objDR("Quantity")DSOrdersNew.Insert()NextEnd SubWhen I run this I get an error message saying: "Unable to cast object of type 'System.String' to type 'System.Web.UI.WebControls.Parameter'."Am I just way out in left field here? I guess I don't mind doing it the old-fashioned way, but it seems like there ought to be a way to do this. Any suggestions would be appreciated. Thanks!
I want to sort on a field that I construct during a query....how can I solve this?Basically what i am doing is selecting mediafiles with comments in descending order.
