Nvarchar(50) To Datetime

Feb 29, 2008

Hi all, Please help.
I have created a new SQL dB and imported a table from Access to SQL.
my date columns in Access have been imported as nvarchar(50).
all dates are in the format dd/mm/yyyy.And there is no bad data

My problem is that in the table design of my new SQL Table, if I change the datatype from nvarchar(50) to datetime I get the error "Arithmetic overflow error converting expression to data type datetime"

I know this is telling me that there is a problem with the format of some of the dates but all my dates are defo dd/mm/yyyy ,none of the data has format mm/dd/yyyy ie a 13th month.I know this because I cut the data down to just 2 pieces of data.
can someone help me get the format into datetime please
Ray..

SQL Field Convert Nvarchar To Datetime

Dec 4, 2007

Hi everyone.

So as the subject says, I have a few fields that are nvarchar but hold date information. Most of these fields I have been able to move to datetime easiliy enough, simply by going into edit mode for the table and converting the fields to datetime. But 1 field is giving me problems I keep getting this error.
quote:- Unable to modify table.
Arithmetic overflow error converting expression to data type datetime.
The statement has been terminated.

I really dont know why I'm getting this error, but I"m assuming it may have to be something like one of the records may not be in date format. But I don't know if this is the case and I don't know how to locate where my problem is coming from.
Any guidance is greatly appreciated.

Thanks.

Modify A Column From Nvarchar(50) To A DateTime

Jun 3, 2007

Hello,

I have a column that is a currently set as nvarchar(50) and is called DateEmployed.
There are over a hundred rows that contain dates which is in nvarchar format.

This column now needs to be changed to a DateTime datatype. (Don't ask me it was not set
to a dateTime when this was first designed - I wasn't here)

However, I have to change this column to a DateTime without destroying the data.

Is there any easy way to write some script or use studio management to change this.

Currently the data is displayed like this in this column dd/MM/yyyy i.e. 25/8/2007.

The method I am using to try and change this is by going to studio management clicking
modify on the column and changing the datatype from a nvarchar(50) to a DateTime.

I get this following error message:
- Unable to modify table.
Arithmetic overflow error converting expression to data type datetime.
The statement has been terminated.

Any suggestions would be most grateful,

Thanks,

Steve

Error Converting Data Type Nvarchar To Datetime

Jun 2, 2008

Hi,

I'm pretty desperat after trying solving the above problem in several days. I hope somone here can help me :-)

I have this stored procedure. When I try to Execute the storedprocedure where I have a date as parameter I get the above error.

I checked (many times), that the input parameter is a datetime format (30-05-2008) and also I checked the tabel and it is datetime format. I checked the table to see if it was english datetime format - but all the datetimes that are listet are listed in danish datetime format DD-MM-YYYY.

In the stored procedure I try this:

fProjectSkuTimeStamp >= @ReducedTime

I can't figure out where it gets that nvarchar from?

My stored procedure look like this:

set ANSI_NULLS ON

set QUOTED_IDENTIFIER ON

set NOCOUNT ON

go

ALTER PROCEDURE [dbo].[GetProjectSkuList]

@fProjectFId AS INTEGER = null, --ProjektId

@ReducedTime AS DATETIME --Tidsrum fra

AS

BEGIN

SELECT tProjectSku.fProjectSkuPId, tProjectSku.fCompanyFId, tProjectSku.fProjectFId,

tProjectSku.fProjectSkuDate,

tProjectSku.fOurContactFId, tProjectSku.fOurContactF2Id, tProjectSku.fOrderFId,

tProjectSku.fProjectSkuTimeStamp,

tProjectSku.fProjectSkuNote1, tProjectSku.fProjectSkuNote2, tProjectSku.fContactFId,

tProjectSku.fStoreTransactionsFId,

tOurContact_1.fOurContactFirstName + ' ' + tOurContact_1.fOurContactLastName AS Responsible,

tContact.fContactFirstName + ' ' + tContact.fContactLastName AS ContactFullName,

Compare Nvarchar(10) With Nvarchar(1000)

Sep 4, 2007

I had this question for quite a long time.

It seems the latter one don't take any extra storage space than the previous one.

As long as the real string length is less than 10.

Is that mean the latter one not cost anything?

I once heard the different is when they are in memory. But not sure of it.

Can anyone explain it and provide some official reference on it?

Thank.

SQL Query: Finding Records Between Datetime Inside Datetime

Mar 17, 2007

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

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...

1-1-2004
1.2.2001

there is no uniformity of the data that is stored currently.
