I have 6 digit value in one column that I need to convert to date-time. I tried two different formula given below.
(DATEADD(day, CONVERT(int, COLUMNNAME)-((1000*(CONVERT(int, COLUMNNAME)/100)))-1, DATEADD(year, CONVERT(int, COLUMNNAME/1000), '1 Jan 1900'))) as Order_date
But this is giving following error message:-
Adding a value to a 'datetime' column caused an overflow. [SQLSTATE=22007, SQLERRORCODE=517]
convert(datetime, (convert (int, COLUMNNAME)), 6) as Order_date
And this is giving incorrect value for date. There is one particular value 118150 that should result into 2018-05-30 :00:00:00, but my statement is returning 2223-06-27 00:00:00
Can anybody please help what is causing error with first statement and how can I modify it to run on entire table.
If I understand the date format correctly, this will work:
select dateadd(day, x % 1000 - 1, datefromparts(1900 + x / 1000, 1, 1))
from (values (118150)) v(x)

NPD.CreatedOn is defined as a datetime datatype column (in SQL Server).
SELECT *
FROM NPDMaster NPD
WHERE DATEDIFF(MONTH, CONVERT(VARCHAR(7), NPD.CreatedOn, 126), CONVERT(VARCHAR(30), GETDATE(), 126)) <= 6
I get this error:
Conversion failed when converting date and/or time from character string.
What can I try to resolve it?
Don't use things like DATEDIFF in the WHERE on your columns, such queries aren't SARGable and thus can (will) perform poorly. If you want rows where the date is on or after the start of the month 6 months ago then do the date logic on GETDATE()/SYSDATETIME()/etc:
SQL Server doesn't have a "start of month" function, but you can use EOMONTH and then add a day:
SELECT *
FROM dbo.NPDMaster NPD
WHERE NPD.CreatedOn >= DATEADD(DAY, 1, EOMONTH(GETDATE(),-7));
You don't need to convert the datetime values to text. DATEDIFF() expects datetime values as second and third argument:
SELECT *
FROM NPDMaster NPD
WHERE DATEDIFF(month, NPD.CreatedOn, GETDATE()) <= 6
The actual reason for the error (as is explained in the documentation), is that ...DATEDIFF implicitly casts string literals as a datetime2 type.
I want to run a query monthly to look for records from the previous month. The where clause will be greater or equal to the 1st day of the month and less or equal to the last day. The difficultly I am having is the dates are stored as numbers in a column with a numeric data type. The format being used is yyyymmdd. We are currently manually changing the where clause, so e.g. show me any records with dates >=20201001 to <=20201031, but we need to automate this process. I have tried a few ways to try and solve this but need some guidance.
So far I've tried:
select concat( CONCAT(cast((Year(DATEADD(month, -1, getdate()))) as numeric),cast((Month(DATEADD(month, -1, getdate()))) as numeric)),'01')
Returns error message operand data type numeric is invalid for concat operator. Works in separate query window returning format yyyymmdd.
SELECT DATEADD(mm, DATEDIFF(mm, 0, (DATEADD(month, -1, getdate()))), 0)
Returns error message arithmetic overflow error converting expression to data type date time. Works partly in separate query window but returns yyyy-mm-dd hh:mi:ss:ms
Any help would be greatly appreciated.
Thanks
The real solution is fix the design; don't store dates in a datatype other than a date and time data type.
What you can do, however, is convert the value of GETDATE() to a numerical value of the same format:
SELECT ...
FROM ...
WHERE NumericalDate >= CONVERT(varchar(8),DATEADD(DAY, 1, EOMONTH(GETDATE(),-1)),112)
AND NumericalDate < CONVERT(varchar(8),DATEADD(DAY, 1, EOMONTH(GETDATE())),112)
For today, this would return rows where NumericalDate is in November 2020 (specifically on or after 20201101 and before but not on 20201201).
Note, I don't "bother" to CAST/CONVERT the varchar to a Numerical data type, as it'll be implicit cast due to data type precedence.
You can use artihmetics like so:
where dates >= year(getdate()) * 10000 + month(getdate()) * 100 + 1
and dates < year(dateadd(month, 1, getdate())) * 10000 + month(dateadd(month, 1, getdate())) * 100 + 1
Compare the month and forget the days.
BETWEEN 20201000 and 20201099 finds the same rows as your example >=20201001 to <=20201031
That means that you do not have to figure out how many days are in the month.
i am trying to pulling data for all shipments with shipmentdate greater than todays date. However, I cant figure out an easy conversion of the format of the nvarchar, i get a out of range value error when trying to run this:
select *
from dbo.BAS_CT_RAW_ARCHIVE_TBL
where SHIPMENTDATE > GETDATE()
Msg 242, Level 16, State 3, Line 1 The conversion of a nvarchar data
type to a datetime data type resulted in an out-of-range value.
Try:
select *
from dbo.BAS_CT_RAW_ARCHIVE_TBL
where convert(date, SHIPMENTDATE, 103) > GETDATE()
To see how to use convert with non-standard dates see this.
Further consideration: use proper datatypes for columns, i.e. don't store dates as strings, but as date datatype - it will prevent you from having such problems.
according to your data format that got from comment below should work
select * from dbo.BAS_CT_RAW_ARCHIVE_TBL
where CONVERT(date, SHIPMENTDATE, 103) > convert(date, GETDATE())
I am trying to find the difference between today's date and a value that is a concatenation of mulitple values but begins with an 8 digit date without any dashes or forward slashes. There's something wrong with my syntax I believe, but I'm not yet skilled enough to see what I'm doing incorrectly. Here is what I have so far:
select DateDiff(dd, (select MIN(CAST(Left(batchid, 8) as Date)) from
[Table]), getdate()) from [Table]
This is returning the following error: "Msg 241, Level 16, State 1, Line 1
Conversion failed when converting date and/or time from character string."
I think your have data where the left 8 is not a valid date in yyyymmdd format. Your can run the following query to find them
select batchid, isdate(Left(batchid, 8))
from [Table]
where isdate(Left(date, 8)) = 0
This is the correct syntax to your query. Your original example had an extra parenthesis which I assume was a typo since your error appears to be data related.
select
datediff(dd, (select min(cast(left(batchid, 8) as date))
from [Table]), getdate())
Could you provide some more details.
Namely, what does batchid look like in 8 digit form? is it YYYYMMDD or DDMMYYYY or MMDDYYYY?
Also could you show us the result of the following?
select MIN(CAST(Left(batchid, 8) as Date)))
from [Table])
Sry for using an answer, i don't have the rep to add a comment directly below.
This was may error. I was working with another table and forgot batchID was not the same for both. The concatenated batchID in the table I posted a question about can't be converted to a date.
Please help me to find out error in my SQL query. I have created this query to compare dates
select * from Joinplans jp
where cast(convert(varchar,GETDATE(),103) AS datetime) BETWEEN
CASE(convert(varchar,jp.planstartDate,103) AS datetime) AND
CASE(convert(varchar,DATEADD(DAY,jp.planDays,jp.planstartDate),103) AS DATETIME)
It's giving me the error:
incorrect near 'AS'
I am using SQL Server 2005.
You wrote case instead of cast in two instances.
If planStartDate is actually a date, then there is no need to cast it to a character column:
Select ...
From Joinplans jp
where GetDate() Between planStartDate And DateAdd(day, jp.planDays, jp.planStartDate)
Now, if planStartDate is storing both date and time data, then you might want to use something like:
Select ...
From Joinplans jp
Where planStartDate <= GetDate()
And GetDate() < DateAdd(day, jp.planDays + 1, jp.planStartDate)
This ensures that all times on the last date calculated via the DateAdd function are included
