How to insert datetime property from asp.net c# to a date column in sql server?

I have a problem using the calender control .. I am getting the date in a textbox... and I have to insert this into the database .. using asp.net with c#
In my web application the field property is set to datetime and in the table the column's datatype is date..
How can I do this??
The error I am getting is:
The conversion of a varchar data type to a datetime data type resulted
in an out-of-range value. The statement has been terminated.
Could anyone help me in this regard?
Thanks in advance

The error i am getting is: The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.
It sounds like you're trying to insert it as a string, which is a generally bad idea. You should use parameterized SQL and set the value as a parameter, still as a .NET DateTime. See the docs for SqlCommand.Parameters for an example of parameterized SQL. You should always keep data in its natural type for as long as possible.
Of course, it's then still possible that you'll get this error if you try to insert a DateTime value which is out of the range that SQL can store. In particular, I believe SQL has a lower limit of 1753 as the year. If your value is DateTime.MinValue for some reason (January 1st, 1AD) then you'd still get this problem. Have you added diagnostics for the value you're trying to insert?

Sorry, my first answer missed your question. Try adding the parameter by doing using the standard parameter system.
command.CommandText = "INSERT INTO FooTable (FooDate) VALUES (#FooDate)";
command.Parameters.AddWithValue("#FooDate", DateToUse.Date);
Using the .Date will only return the date part of the object. Here's another reference to it Date vs DateTime

If you're using a parametrized query, I have no trouble whatsoever to insert that DateTime from the ASP.NET calendar control into a SQL Server database table that contains a column of type DATE.
Use something like this:
// define INSERT statement - of course, yours will look quite different!
string insertStmt = "INSERT INTO dbo.DateTest(TheDate) VALUES(#DateValue);";
// set up connection and SqlCommand to do insert
using(SqlConnection conn = new SqlConnection("....your-connection-string-here...."))
using (SqlCommand cmd = new SqlCommand(insertStmt, conn))
{
// add the parameters - the #DateValue - to the SqlCommand object and
// define it's datatype (on the database) and set the value to be stored
cmd.Parameters.Add("#DateValue", SqlDbType.Date).Value = Calendar1.SelectedDate;
// open connection, execute command, close connection
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
}

Try one thing first, try to insert 01/01/2012 in the column, because that could because of wrong culture.... it could be mm/dd/yyyy or dd/mm/yyyy
try this 01/01/2012 first and see if thats working.
thanks

Storing C# datetime to postgresql TimeStamp

I'm working on an app that stores data in a spreadsheet to a Postgresql database. I'm familiar with C# and .Net but not so well with Postgresql. I'm having trouble storing a DateTime value into a TimeStamp column; I keep getting an error message: Failed to convert parameter value from a DateTime to a Byte[]. Any advice would be appreciated.
string query = "INSERT INTO organizer(organizer_name, contact_name, phone, alt_phone, created_date, last_update) " +
"VALUES('#name', '#contactname', '#phone', '#altphone', '#created', '#updated')";
OdbcCommand cmd = new OdbcCommand(query, con);
cmd.Parameters.Add("#name", OdbcType.VarChar);
cmd.Parameters["#name"].Value = org.Name;
cmd.Parameters.Add("#contactname", OdbcType.VarChar);
cmd.Parameters["#contactname"].Value = org.ContactName;
cmd.Parameters.Add("#phone", OdbcType.VarChar);
cmd.Parameters["#phone"].Value = org.Phone;
cmd.Parameters.Add("#altphone", OdbcType.VarChar);
cmd.Parameters["#altphone"].Value = org.AltPhone;
cmd.Parameters.Add("#created", OdbcType.Timestamp).Value = DateTime.Now;
cmd.Parameters.Add("#updated", OdbcType.Timestamp).Value = DateTime.Now;
con.Open();
cmd.ExecuteNonQuery();

I don't have a PostgreSQL db handy to test with, but I believe that you are seeing this because the OdbcType.Timestamp is actually a byte array, not a time and date. From MSDN:
Timestamp: A stream of binary data (SQL_BINARY). This maps to an Array of type Byte.
This is probably because the timestamp datatype, in SQL Server, is
a data type that exposes automatically generated, unique binary numbers within a database. timestamp is generally used as a mechanism for version-stamping table rows.
I would try using OdbcType.DateTime, which seems to map to the concept behind PostgreSQL's timestamp.
EDIT:
Here is a useful post which summarizes the mappings between PostgreSQL and .NET.

You've got a few solutions here...I'm going to assume the organizer table has the created_date and last_update as timestamp fields, correct? The silliest answer is to change those to varchar fields. heh.
2 better answers...I'm assuming this is a formatting error where DateTime.Now doesn't return in the format pgsql wants:
Since you are just giving it the current timestamp
you can define your table to default these columns to now() and then not pass values to this column, on an insert the table would just populate that with the default of now().
instead of defining the variable to DateTime.Now and then passing the variable, just send postgres now() and it will populate it in the format it feels right.
And second potential is to format the date into what PG expects as part of the insert statement...I'd need to know what DateTime.Now gives for a value to format it to what pg wants to see. This might be a bit of string manipulation...

date time now format

Hi I try to insert into DB date time and the Column is date type what I need to do?
this is the code
string query = "INSERT INTO Feedback (user_Name, date_of_, Praise) VALUES ('"+TextBox1.Text+"',"+DateTime.Now+",'"+TextBox2.Text+"')";
SqlCommand cmd = new SqlCommand(query, con);
con.Open();
cmd.ExecuteNonQuery();
con.Close();

I would advise against using time from the application server to insert values into the database. The most basic example how that can go wrong is that you could have two servers set to different time zones, that use the same database. What server's time is the right time?
Other thing is the neccessary transformation of a datetime to string when you are using inline SQL statements. If the application server and the database server are set to different cultures, you need to be extremely careful not to insert May 2nd (02.05), when you want to insert Feb 5th (02.05).
Sure, all these issues are avoidable, but why bother with them at all, when the RDBMS can do all that for us?
BTW, even if you don't want to use stored procedures, use parameters.
This code should be reformated like:
string query = "INSERT INTO Feedback (user_Name, date_of_, Praise) VALUES (#username, getdate(), #praise)";
SqlCommand cmd = new SqlCommand(query, con);
SqlParameter param = new SqlParameter("#username", SqlDbType.Text);
param.Value = text1;
cmd.Parameters.Add(param);
param = new SqlParameter("#praise", SqlDbType.Text);
param.Value = text2;
cmd.Parameters.Add(param);
con.Open();
cmd.ExecuteNonQuery();
con.Close();

Don't include the value directly in your SQL.
Use a parameterized query instead. There's no point in messing around with string formatting when the database is quite capable of accepting a prepared statement with a DateTime parameter.
You should get in the habit of using query parameters for all values which can't be simply hard-coded into the SQL to start with. For example, your query is currently just blithely taking the contents of TextBox1.Text and inserting that into the SQL. That's a recipe for a SQL injection attack.
You should separate the code (the SQL) from the data (the values). Parameterized queries are the way to do that.
EDIT: Using a built-in function in the SQL is fine, of course, if you're happy to use the database's idea of "now" instead of your client's idea of "now". Work out which is more appropriate for your situation.

Why don't you use a TIMESTAMP column in your database ? Seems like overhead by inserting it through your code.
The following link provides more info:
http://msdn.microsoft.com/en-us/library/aa260631(SQL.80).aspx
edit: Set the default value of your database column as CURRENT_TIMESTAMP (Transact-SQL), and leave the column name out of your insert statement. The current date and time will be inserted by your database automatically. No problem with conversions anymore!

Replace DateTime.Now with DateTime.Now.ToString("yyyy-MM-dd");
Also, you should really parameterize your insert statement so that you cannot fall victim of a SQL injection attack.

There is a NOW() function in most SQL implementations.

You have to convert your DateTime to an Sql DateTime literal. The easiest way to do it is this:
DateTime.Now.ToString(System.Globalisation.CultureInfo.InvariantCulture)
Yet, especially for DateTime.Now, you may use some Sql function, such as GetDate() but that often depends on your database server.

You can use the Date property:
DataTime.Now.Date

c# query is not returning anything

here is my query:
select reporttime, datapath, finalconc, instrument from batchinfo
join qvalues on batchinfo.rowid=qvalues.rowid where qvalues.rowid
in (select rowid from batchinfo where instrument LIKE '%TF1%' and reporttime
like '10/%/2010%') and compound='ETG' and name='QC1'
i am running it like this:
// Create a database connection object using the connection string
OleDbConnection myConnection = new OleDbConnection(myConnectionString);
// Create a database command on the connection using query
OleDbCommand myCommand = new OleDbCommand(mySelectQuery, myConnection);
it does not return any results.
when i try this same query in sql server GUI it returns lots of rows
is there a problem specifically with the syntax of the query for c#?
please note that if i simplify the query like select * from table, there is no issue

Can you try using SqlCommand instead of OleDbCommand?
According to MSDN it: Represents a Transact-SQL statement or stored procedure to execute against a SQL Server database.
So if you really are using SQL Server 2008 you should probably use this. Any reason you are not?

How are you setting up the mySelectQuery string?
Could this be a problem with an escape character?
If you're not doing it already,
string mySelectQuery = #"query text here";

Personally I would run query profiler to see what query (if any) is being run, and then go from there.

Are you sure you are connecting to the same database in your code?
On a side note do you need the inner select? Couldn't you write this query as follows.
select reporttime,
datapath,
finalconc,
instrument
from batchinfo
join qvalues on batchinfo.rowid = qvalues.rowid
where compound = 'ETG'
and name = 'QC1'
and batchinfo.instrument like '%TF1%'
and batchinfo.reporttime like '10/%/2010%'

Edit - Never mind, just read the comment that your date is in a varchar field. Will leave this here since it may still be useful information.
Try this:
reporttime like 'Oct%2010%'
I have a test table here and when I query it using
where LastModified like '11/%/2010%'
no rows are returned, although all of the rows in the table have dates in November 2010. When I run the same query using like 'Nov%2010%', it returns all rows.
Details can be found here:
The LIKE clause can also be used to search for particular dates, as well. You need to remember that the LIKE clause is used to search character strings. Because of this the value which you are searching for will need to be represented in the format of an alphabetic date. The correct format to use is: MON DD YYYY HH:MM:SS.MMMAM, where MON is the month abbreviation, DD is the day, YYYY is the year, HH is hours, MM is minutes, SS is seconds, and MMM is milliseconds, and AM designates either AM or PM.

C#+linq - Inserting DateTime value to the Db in the right format

I have a Db server with DateTime fields in the format of "yyyy-MM-dd mm:hh:ss"
I'm trying to use linq2sql to insert a DateTime member to a DateTime field in one of my tables.
When I do it in SQL I convert the DateTime as following:
"Insert into .... Convert(datetime, getdate(), 120) ..."
But when I try to submit the object from Linq the date time inserts in the wrong format.
Is there a way to define the format that will be inserted to the Db in Linq?
Or is it a DateTime object Issue?

You shouldn't be dealing with a string format when you pass dates and times to the database, any more than you would if you were passing a number. The database should be handling all this for you without any conversions. This is true whether you're using LINQ or within the SQL - almost any time you have to manually do string conversions between types at the database level, you should look for a better solution.
If you read the value back out of the database (as a DateTime again) does it have the right value? If not, in what way is it wrong?
