converting date/time to just date?

I have a table that's of type date/time (i.e. 01/01/1900 00:00:00).

What I want is to do the following:

Say you have these records:

person | date-time
---+--------
jim | 06/02/2004 00:05:52
jim | 06/02/2004 05:06:21
jim | 06/02/2004 05:46:21
jim | 06/15/2004 11:26:21
jim | 06/15/2004 11:35:21
dave | 06/04/2004 09:35:21
dave | 06/04/2004 11:05:21
dave | 06/06/2004 10:34:21
dave | 06/08/2004 11:37:21

I'd like the results to count how many days and return

person | days
---+---
jim | 2
dave | 3

How would I do this?

Hi Sugapablo,

SELECT person,
COUNT(DISTINCT CONVERT(CHAR(8), date-time, 114)) AS days
FROM YourTable
GROUP BY person
(untested)

Converting date to Varchar? and Varchar to Date?

I have a column of data in a table that has date formatted as '2006-03-26 00:00:00.000'

What T-SQL command that will alter the column so that it is now Varchar '03-26-2006'?

I also want to know how to do the opposite... if I have '03-26-2006' via command, how do I convert the column of the table to be datetime from varchar

This should give you an idea of how to handle these conversions:

DECLARE @.MyDateTimeValue datetime
SET @.MyDateTimeValue = '2006-03-26 00:00:00.000'

SELECT convert( varchar(10), @.MyDateTimeValue, 101 )

-
03/26/2006

SELECT cast( '03/26/2006' AS datetime )

2006-03-26 00:00:00.000

converting date time field

Hi,

I'm trying to report on the time records are created , but not to include the date. So for a month long period, I want to know how many records have been created between 8am & 9am. I can group the records and display by hour, but as the database is a time date field, it displays for each date as well.

I think I probably need to create a formula that will strip out the date information, then I can group by hour and that will return what I need, but I have no idea how create such a formula...

Any ideas?

Thanks,

Matt.What is your Database?
Write a Stored Procedure having the query group by Time and use that sp to design the report

Converting Date String to Date

Hi there,

I am trying to convert a date string (YYYYMMDD) to a date (DDMMYY). Using the following formula, I have met with partial success, the day and the year pull through correctly for each entry but the month is always (01).

E.g. (20011031 = 31/01/2001) or (20011201 = 01/01/2001) or (20031208 = 08/01/2003)

My formula is as follows.

//Convert The Status Changed Date

NumberVar xy := tonumber(Left({AUT001.Date Status Last Changed},4));
NumberVar xd := Day(Datevalue (tonumber(Right({AUT001.Date Status Last Changed},2))+1));
NumberVar xm := Month(Datevalue (tonumber(Mid({AUT001.Date Status Last Changed},5,2))+1));

Date(xy,xm,xd)

I am using Crystal 10 and am totally stumped.

Any help would be very much appreciated, thanks in advance.Datevalue of a number ,say x, will return December (30+x), 1899.
So, according to ur formula if the month is 'May' then xm will contain January 5,1900(December (30+5+1),1899).Have added 1 additionally as u have added 1 in ur formula.
So when u take the month fn. it wil return January which is 1(as u have stated).
Hence datevalue of the number(for months at the max. can be 12) will return a date in January only and hence always u get month as January.

tried in crystal 8 and the following worked not sure about Crystal 10

numbervar xy := tonumber(left({@.stringdate},4));
numbervar xd := tonumber(right({@.stringdate},2));
numbervar xm := tonumber(Mid({@.stringdate},5,2));

Date(xy,xm,xd);|||Thank worked fine, thanks very much.

help ?
What is the date formay you want to get? Note that all datetime values will
mapped to an ISO format. If you want your own format, CONVERT to a string in
your select statement.

converting date field from Informix to SQL nvarchar

I copying data from our Informix 7.2 database into SQL Server 2K using DTS but hitting errors during the process. There appears to be date data within Informix that will not convert properly when moving into SQL. Since the error is appearing at the 1.5million (approx.) record. I figured on changing from datetime to nvarchar. Works like a charm! :-)

My new problem is converting it back to datetime so I can query against the date without having to create scripts to parse the field.

The data in SQL currently looks like this -> 2000-11-29 (nvarchar(50))
I would like to have it -> 11/29/00 (datetime)

Any help is greatly appreciated!

The goodness we share is rewarded twice!try to find the record that cause the failure:
select * From <your table name> where isdate(<date varchar column name>)=0

varchars in yyyy-mm-dd format usually converted to dates data type without problems...|||Thank you for the reply.

So your saying, if the table name is findet (financial detail) and the column name is fdate (nvarchar, 50).

Run the select against the varchar column?|||You've got data that can't be converted to date...

To see the offending rows...

SELECT * FROM findet WHERE ISDATE(fdate) = 0|||OK. I am testing it now. When I attempted to convert the column in Enterprise Mgr, I got the following error:

/*

Did you run this?

What did you get?

$1,000 bucks you've got non date data in that column|||That worked!!! Thank you for your help!!!|||What worked?

Did you find non date data?|||before you change the column type find what cause the conversion error!|||There was data mis-entered 0004-04-10 (example). Since the year is out of range, converting it to datetime was not possible.

Now, how do I script my DTS package to exclude records that are out of range and put them in a separate table for exception reporting?

Again, thank you for your help! It is greatly appreciated!!!|||just load the entire data to table with varchar column then copy the wrong date format to errors table and delete these records from the original table, convert the good data from the original table into target table drop the original table fix the failed record and enter them into the target table

Converting Date Data type in stored procedure

HI Experts...

I am using SQL SERVER 2005 standard edition

I have encountered a problem regarding converting date data type in stored procedure

As i was having problem taking date as input parameter in my stored procedure, so, then I changed to varchar (16) i.e.

CREATE PROCEDURE sp_CalendarCreate
@.StDate VARCHAR(16) ,
@.EDate VARCHAR(16),

then I am converting varchar to date with following code

DECLARE @.STARTDATE DATETIME
DECLARE @.ENDDATE DATETIME

SELECT @.STARTDATE = CAST(@.STDATE AS DATETIME)
SELECT @.ENDDATE = CAST(@.EDATE AS DATETIME)

When I try to execute the procedure with following code

execute sp_CalendarCreate @.stdate='12-1-06',@.edate='20-1-06'

but it gives me following error

Msg 242, Level 16, State 3, Procedure sp_CalendarCreate, Line 45
The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.

Can any one tell me the solution of that problem (at ur earliest)

regards,

Anas

execute sp_CalendarCreate @.stdate='1-12-06',@.edate='1-20-06'

|||

Thanx for your reply....

yes i had sorted that out b4 u replied me... i.e. sql server uses date format mmddyy or yyyyddmm (american format)

and i was using UK/european standards

btw thanx very much for support

regards,

Anas

|||It is best to use ISO unseparated date format (YYYMMDD) or ISO 8601 (YYYY-MM-DDThh:mm:ss.nnn) datetime format for specifying values. This way you don't have to worry about DATEFORMAT or language settings of the server. Also, using varchar and converting to datetime is not a good and clean approach. Use the correct data type for the values so you can get the best benefit in terms of type checking, domain validations etc. Additionally, with your approach you will get into performance problems because parameter sniffing of the variables used in the SELECT statement will not work due to use of local variables and not parameters. See the whitepaper on compilation, caching in MSDN for more details.
