Converting empty string to Null when inserting/updating

I am using the following query to calculate date differences:
select ........DATEDIFF(d, recruitment_advertising.advertising_date, career_details.RTS_Email AS Datetime) AS Ad_to_RTS_days FROM ....

I have stored all my dates as NVARCHAR because of the issues with localization.
If the value is an empty String my output is eg: -38700. which is way off and incorrect. Some of the values in my table areNULL and they produce the correct result.

Is there a T-SQL statement to replace empy Strings with the NULL value in my tables.
I'd like to use it as a trigger when inserting or updating to convert empty strings to NULL
before the values are inserted.

Thanks guys.

You REALLY should store your dates as a datetime. There is no localization "Problem" with datetimes if you use them correctly, and you can't sort and/or generate good indexes if they are stored in a nvarchar field (Unless you specifically use the YYYYMMDD or YYYY-MM-DD format).

That aside, yes, try NULLIF() like:

INSERT INTO MyTable(col1) VALUES (NULLIF(@.val1,''))

Converting datetime to integer and back

Hi all,

I have a problem converting datetime to integer (and than back to
datetime).
Depending whether the time is AM or PM, same date is converted to two
different integer representations, which holds as true on reversal
back to datetime.

AM Example:

declare @.DI integer; declare @.DD datetime
set @.DI = cast(cast('3/12/2003 11:34:02 AM' as datetime) as integer)
set @.DD = cast (@.DI as datetime)
print @.DI; print @.DD

Result:
37690
Mar 12 2003 12:00AM

PM Example:

declare @.DI integer; declare @.DD datetime
set @.DI = cast(cast('3/12/2003 11:34:02 PM' as datetime) as integer)
set @.DD = cast (@.DI as datetime)
print @.DI; print @.DD

Result:
37691
Mar 13 2003 12:00AM

Now, this is not a big problem if I knew that this is how it is
supposed to work. Is this how SQL Server is supposed to work?Nikola (nigel35@.hotmail.com) writes:

Apparently, SQL Server rounds to the nearest wholest int. I wouldn't
say this makes much sense to me.

Then again, I have to admit that I don't really see the point with
converting datetime values to integer.

In any case, the workaround should be simple, first chop of the
time portion.

VB6 will allow a similar translation and it has the same problem: a real
number is returned where the fractional (i.e. right of the decimal point)
part represents the time. So, converting from datetime to an int carries a
hidden conversion that rounds to get the integer. Check this out (I used
money, although I assume float or real would suffice).

declare @.d datetime
declare @.n money

set @.d = '3/12/2003'
set @.n = convert(money, @.d)
print convert(varchar, @.n) + ' - ' + convert(varchar, @.d)

set @.d = '3/12/2003 11:34 AM'
set @.n = convert(money, @.d)
print convert(varchar, @.n) + ' - ' + convert(varchar, @.d)

set @.d = '3/12/2003 11:34 PM'
set @.n = convert(money, @.d)
print convert(varchar, @.n) + ' - ' + convert(varchar, @.d)

set @.d = '3/13/2003'
set @.n = convert(money, @.d)
print convert(varchar, @.n) + ' - ' + convert(varchar, @.d)

Actually there is an even simpler workaround:

declare @.d datetime
declare @.i int

SELECT @.d = '20020202 11:59:00'
SELECT @.i = convert(float, @.d)
SELECT @.i

SELECT @.d = '20020202 12:01:00'
SELECT @.i = convert(float, @.d)
SELECT @.i

This works, because when convering from float to int, truncation occurs...

Converting Date-Time to Date Conundrum

I need to be able to convert a Date-Time Field to a Date Fied in my SQL
Tables.
Using CONVERT (varchar, "Date-Time Field", 103) gives me the correct result
but because it converts the date value to a string I can say goodbye to
localization.... any ideas on how to convert the field but still allow
localization.Try this function...
CREATE FUNCTION [dbo].[fnRemoveTimeFromDateTime] (@.InputDate DATETIME)
RETURNS DATETIME AS
BEGIN
DECLARE @.OUTPUT AS SMALLDATETIME
SET @.OUTPUT = CONVERT(DATETIME, FLOOR(CONVERT(FLOAT, @.InputDate)))
RETURN @.OUTPUT
END

Converting Date-Time to Date

Hi: I am new to Reporting Services.
My issue is that I have a Date-Time Field which I want to use as a column heading for a crosstab. However since there are multiple date entries with varying times I get multiple column headings. Could anyone tell me how to convert this datetime field to a date field so that I only get one column per day.
ThanksThere are are number of VB.Net functions for manipulating dates which you
could use for this.
The simplest (but probably not most efficient) way would be to convert the
date to a string then back to a date: =CDate(CStr(Fields!DateTime.Value))
You might want to consider doing the conversion in your query instead.

Converting Datetime to Date

I need to convert a datetime, coming from a database table, to a date. How
do I do this within my report?
--
DonIs this just for display or do you really want to convert to date for further
manipulation as a date?
If it is only for display, use =format(Fields!MyDateField.Value,
"MMM-dd-yyyy") or something like it.
If it is for further manipulation as a date, use
=CDate(Fields!MyDateField.Value)

You should just have

use containers such as list or table data region to put your textboxes in.
The Format function does not have a scope parameter, so it should work. The
First function you are using is an aggregate function, so it may need a scope
parameter.
But the first thing you need to do is to place a list or table data region
on your screen. Bind it to a dataset using the Properties dialog, then add
textboxes inside of it.

Converting dates into floats

I have an odd database that has a date stored in a float field. The
dates originate in an external database, which is imported record-by-
record, with data cleanup and conversion, into SQL Server. We do many
of these sorts of conversions, but normally they are put into a
datetime field instead of a float.
Everything seems to work perfectly under VB. However, I am in the
process of converting from VB into SQL for a variety of reasons. This
floatdate is causing a problem, as it is always off by two days. Let
me give you an example...
On March 7 we purchased some XXX, who's expiry date is 6/5/2008. I
read in the date from the external database, which stores it as a
string: "20080605". Here is the code I use to convert it...
Function RealDate(Datestring) As Date
Dim Yr As String
Dim Mth As String
Dim Dy As String
On Error GoTo notadate
Yr = Left(Datestring, 4)
Mth = Right(Left(Datestring, 6), 2)
Dy = Right(Datestring, 2)
RealDate = Mth & "/" & Dy & "/" & Yr
Exit Function
notadate:
RealDate = 1 / 1 / 1900
End Function
So far so good. I then put that result, a VB Date, directly into the
float field in the database. If I then read that back out in VB and
cast it to a date (which is automatic if you want) I get back the same
value.
However, when I do this in SQL, I get a _slightly_ different date:
cast(price2 as datetime) as expiry
returns 2008-06-07 00:00:00.000
It's off by _two days_. At first I thought this was an epoch issue.
Looking on the 'net I see that VB uses 1/1/1970 as the epoch while SQL
Server uses 1/1/1900. Is this understanding correct? If so, how is it
that the resulting date in SQL is only off by two days, and not 70
years?
MauryMaury,
SQL Server's zero day is 1900/01/01, but I believe that (due to a mistake
somewhere along the line) that Visual Basic's zero day is 1899/12/30. (I
believe it was supposed to be 1899/12/31, so that makes two mistakes, one
for each day that your calculation is off.)
I am relying on memory since I cannot find the reference right now.

LOL! Ok, that DOES explain it. I'll just remember to -2 from now on.

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

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?

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.

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!

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.

Converting Date

I am unable to convert following date format in seconds (ss). Plz provide me query for the same.
Date Available :
2007-03-27 09:55:00.000select convert(datetime, '2007-03-27 09:55:00.000')

??|||select convert(datetime, '2007-03-27 09:55:00.000')
Yes, and the seconds are extracted by:
select datepart(ss, convert(datetime, '2007-03-27 09:55:00.000'))|||even the convet part of

select datepart(ss, convert(datetime, '2007-03-27 09:55:00.000'))

can be avoided and used as

select datepart(ss,'2007-03-27 09:55:00.000')|||but select datepart(ss,'2007-03-27 09:55:00.000') yields 0

i think perhaps milind wanted the answer to be 3383974800, which is that datetime converted in seconds in SQL Server

note that in unix timestamp format, the value would be 1175003700|||Perhaps, yes. Then the query he asked would be:

SELECT 3383974800|||no, not really, because you don't get that answer without doing a conversion

for example, what is the answer for '2006-09-09 09:37'?|||'2006-09-09 09:37' is not one of the available dates listed in the OP. ;)

Seriously, I think we need Milind to clarify what s/he wants.|||'2006-09-09 09:37' is not one of the available dates listed in the OP. ;)

good one :cool:

converting Datatypes:

Hi All,

how do you convert from a date to an int ? as well as converting from Varchar to and Int

in SQL server 2000 ?

I am retrieving the GetDate() which i store in column as Varchar, i then want to use it within my select statement to calulate data which i want to return i.e

DECLARE @.DateValue AS VARCHAR(20)

SELECT @.DateValue = ApplicationSettingValue FROM ApplicationSettings WHERE ApplicationSettingKey = 'ProcessDate'

print convert(int,@.DateValue) - 5
print GetDate() - 35

SELECT ccy_code, NULL, xrate_date, sterling_xrate
FROM SylvanTrans.dbo.SIADHP_XRate_Hist
WHERE xrate_date >= (CONVERT(int, @.DateValue) - 35 )
ORDER BY xrate_date

now my as you can see in my WHERE CLAUSE i want to calculate what is returned using the GETDATE() stored in my @.DateValue Variable, but the conversion throws a syntax error:

Server: Msg 245, Level 16, State 1, Line 3
Syntax error converting the varchar value 'GetDate()' to a column of data type int.

what am idoing wrong? i know it is something simple, unless there is no conversion from varchar to int?, i also tried setting the datatype for my variable as datetime but i got the same sort of error with DATETIME replacing the VARCHAR in the error!!!

thanks

regards

Hi,

why don′t use use the associated function for dealing with datetime like DATEADD ? You can also add negative dateparts to a datetime like
DATEADD(dd,-35,SomeDate)

HTH, Jens K. Suessmeyer.

http://www.sqlserver2005.de
|||

thanks for your reply,

yes i did see that function, but i neet to have a seperate table which stores the GetDate() so that in my sotred procs

i can do a select on its location and do things like :

select * from tablename

where @.valueDate - 1 > 5

where @.valueDate has the getDate () from my Applicationsettings Table, if i use the DateAdd() i wont be able to do this you see...

|||I think I did not got your point. COuld you explain this in more detail ?

Converting datatype on column...

What impact will changing the datatype of a column from
smalldatetime to datetime? Currently, I need to allow for record insertion
where the date may exeed year 2079.Eric wrote:

That should be fine. The column will require twice the number of bytes
of storage in order to support datetime (8 bytes total). Newly inserted
values will show additional precision unless you account for this.
create table ABC (MyDate smalldatetime)
insert into dbo.ABC values (getdate())
insert into dbo.ABC values ('2005-01-10T14:22:22')
Select * from dbo.ABC
MyDate
--
2005-09-01 17:45:00
2005-01-10 14:22:00
Alter Table dbo.ABC
ALTER COLUMN MyDate DATETIME
Select * from dbo.ABC
MyDate
--
2005-09-01 17:45:00.000
2005-01-10 14:22:00.000
insert into dbo.ABC values (getdate())
insert into dbo.ABC values ('2005-01-10T14:22:22')
Select * from dbo.ABC
MyDate

Converting C++ Unix time_t Julian date to SQL date

I've just been trying to do this. I looked on Google and it seems to
be a common problem with no obvious solution. I've seen various
solutions which don't seem exactly elegant, so I figured I'd post the
solution I came up with. It's effectively a single line solution,
albeit with various embedded calls. It makes an adjustment for the
local timezone too!
DECLARE @.time_t INT
SET @.time_t = 1090834321 /* 10:32am, July 26th 2004 BST */
DECLARE @.timestamp DATETIME
SET @.timestamp = dateadd (ss, datediff (ss, GetUTCDate(), GetDate()),
dateadd (ss, @.time_t, '19700101'))
PRINT @.timestamp
Hope that helps. If there's a problem with it, let me know!
andytHi Andy,
I have received a data file and it has julian dates. How Do I convert them
to normal dates? I tried this code and replaced the variable with the date I
received, and All it did was give me the same date with different times.
Any ideas? What does the hardcoded '1970-01-01' do?

You can convert it like this:

SELECT DATEADD(SECOND,@.ts,'19700101')

Just use CONVERT or CAST:
Select CONVERT(char(30), MyDecimal) From ...
Select CAST(MyDecimal as char(30)) From ...
David Gugick
Imceda Software

Hi David,
The orinal question was crossposted to a total of three groups:
* comp.databases.oracle.misc
* microsoft.public.sqlserver.programming
* comp.databases.oracle
The followup-to was set to only the SQL Server group. The use of CONVERT

question. I have no idea why the original poster has included two Oracle
groups in his crossposting.

converting a number into a date type using an expression

I am loading data from an iseries into a sql server 2005 DB. Our dates are stored as a numeric value in a format of CYYMMDD where C = Century indicator 20'th is 0 and 21'st is 1, YY = Year, MM = Month and DD = Day!

Today would be 1070701. Now I want to use a derived column which which would be of type date using an expression to do the conversion.

Usually, we would add 19000000 to the number to give us 20070701 then I'd convert it to a string and then substring into a date format.

I'm just getting started with SQL 2005 so I don't know how to do this using an expression.

Any help would be greatly appreciated.

Thanks,

Gray

I think your approach sounds valid. You're going to have to parse it with substring and build it into a date format. Then you can cast the string to a date/time field.

(DT_DBTIMESTAMP)(substring([YourColumn + 19000000],x,y) + "/" + .......)

|||

Hi Phil,

Thanks for the info ... it really helped ... here's my final expression ...

(DT_DBTIMESTAMP)(SUBSTRING(((DT_STR,8,1252)(YearMonthDay + 19000000)),5,2) + "/" + SUBSTRING(((DT_STR,8,1252)(YearMonthDay + 19000000)),7,2) + "/" + SUBSTRING(((DT_STR,8,1252)(YearMonthDay + 19000000)),1,4))

Thanks again,

Gray
