Getting Error: The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.
How do I use dates that are in the future?
So you have invalid dates for Feb.
I would look at EOMONTH (end of month) function https://msdn.microsoft.com/en-us/library/hh213020.aspx
So you can just pass in the 1st of the month and SQL will work out the rest.

This seems like it should be fairly simple and straight forward but I haven't yet found the right combination. I have a column called last_assess_yr that is an integer. I am trying to find all rows from my_table where '01-01' + 'year' < current_date and give them a value in a new column. I have the following:
SELECT last_assess_yr,
CASE
WHEN format('01-01-%s'::text, last_assess_yr)::timestamp without time
zone < current_date
THEN YES
ELSE NO
END AS assess_value
FROM my__table
but, the results are not correct
You don't actually need to convert the integer into a timestamp, you could just compare the extracted year to the integer.
select
case when last_assess_yr < extract('year' from current_date)::int
then 'YES' else 'NO'
end
However for reference the following will work:
select
case when format('01-01-%s'::text, 2017)::timestamp < current_date
then 'YES' else 'NO'
end
i.e. you do not need to remove time (of day) when you convert a string of '01-01-2017' to a timestamp.
and: I assume YES and NO also need to be treated as literals: 'YES' and 'NO'
In case someone else is looking, this worked for me:
WHEN last_assess_yr > 0 AND format('%s-05-05'::text, w.last_assess_yr)::timestamp <
current_date THEN 'yes'
ELSE 'no'
END
I want to sort column value(DateTime) on a condition(and event occurring before March 1st 2016 as 'Preseason',
event Occurring after march 31st 2016 as 'PostSeason' Else 'Season'.
--Query---
Select EventDate= Case
When EventDate <'01-03-2016' then 'PreSeason'
When EventDate >'31-03-2016' then 'PostSeason'
Else 'Season'
End,
EventName From tblEvent
--Error Message
'Msg 242,The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.'
Something like..
ORDER BY
CASE
WHEN ISDATE(DateTime) = 1 THEN
CASE DateTime
WHEN <= '2016-03-01' THEN 1 -- Preseason
WHEN >= '2016-03-31' THEN 3 -- PostSeason
ELSE 2 END -- Season
ELSE 4 END, -- Not a date, figure out how to handle
DateTime
-- ok, Was a date format issue. i used a European Date Format(dd-mm-yyyy) in my query but the system i use takes USA date Format(mm-dd-yyyy) so my query failed.
**
Solution
**
Select Cast(Case
When EventDate <='01/01/2016' then 'PreSeason'
When EventDate >='12/31/2016' then 'PostSeason'
Else 'Season'
End As Varchar(25)) as Season, EventName From tblEvent
Thanks for Support!!!!
Assume a user tries to cast a number (year of birth) into a date.
select year_of_birth, cast(year_of_birth as date) from visit_occurrence
And gets this error :
cannot cast type smallint to date
What is the proper way?
e.g., cast(cast(YOB as string)+'-01-01' as date) does not work either.
use
select year_of_birth, to_date(cast(year_of_birth as text), 'YYYY') from visit_occurrence ;
I have a simple question regarding T-SQL. I have a stored procedure which calls a Function which returns a date. I want to use an IF condition to compare todays date with the Functions returned date. IF true to return data.
Any ideas on the best way to handle this. I am learning t-sql at the moment and I am more familar with logical conditions from using C#.
ALTER FUNCTION [dbo].[monday_new_period](#p_date as datetime) -- Parameter to find current date
RETURNS datetime
BEGIN
-- 1 find the year and period given the current date
-- create parameters to store period and year of given date
declare #p_date_period int, #p_date_period_year int
-- assign the values to the period and year parameters
select
#p_date_period=period,
#p_date_period_year = [year]
from client_week_uk where #p_date between start_dt and end_dt
-- 2 determine the first monday given the period and year, by adding days to the first day of the period
-- this only works on the assumption a period lasts a least one week
-- create parameter to store the first day of the period
declare #p_start_date_for_period_x datetime
select #p_start_date_for_period_x = min(start_dt)
from client_week_uk where period = #p_date_period and [year] = #p_date_period_year
-- create parameter to store result
declare #p_result datetime
-- add x days to the first day to get a monday
select #p_result = dateadd(d,
case datename(dw, #p_start_date_for_period_x)
when 'Monday' then 0
when 'Tuesday' then 6
when 'Wednesday' then 5
when 'Thursday' then 4
when 'Friday' then 3
when 'Saturday' then 2
when 'Sunday' then 1 end,
#p_start_date_for_period_x)
Return #p_result
END
ALTER PROCEDURE [dbo].[usp_data_to_retrieve]
-- Add the parameters for the stored procedure here
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
IF monday_new_period(dbo.trimdate(getutcdate()) = getutcdate()
BEGIN
-- SQL GOES HERE --
END
Thanks!!
I assume you are working on Sql2008. See documentation of IF and CASE keywords for more details.
CREATE FUNCTION dbo.GetSomeDate()
RETURNS datetime
AS
BEGIN
RETURN '2012-03-05 13:12:14'
END
GO
IF CAST(GETDATE() AS DATE) = CAST(dbo.GetSomeDate() AS DATE)
BEGIN
PRINT 'The same date'
END
ELSE
BEGIN
PRINT 'Different dates'
END
-- in the select query
SELECT CASE WHEN CAST(GETDATE() AS DATE) = CAST(dbo.GetSomeDate() AS DATE) THEN 1 ELSE 0 END AS IsTheSame
This is the basic syntax for a T-SQL IF and a date compare.
If you are comparing just the date portion for equality you will need to use:
select dateadd(dd,0, datediff(dd,0, getDate()))
This snippet will effectively set the time portion to 00:00:00 so you can compare just dates. So in use it will look something like this.
IF dateadd(dd,0, datediff(dd,0, fn_yourFunction())) = dateadd(dd,0, datediff(dd,0, GETDATE()))
BEGIN
RETURN SELECT * FROM SOMEDATA
END
Hope that helps!
What I am trying to do is get a result from sql where the dates are in a certain range but its not working correctly, here is my query.
DECLARE #CurrDate DATETIME
SET #CurrDate = GETDATE()
SELECT dbo.ProductDetails.PartnerID
,dbo.ProductDetails.ProductID
,dbo.Products.ProductName
,StartDate
,EndDate
FROM dbo.ProductDetails
INNER JOIN dbo.Products
ON dbo.ProductDetails.ProductID = dbo.Products.ProductID
WHERE CONVERT(VARCHAR(10),StartDate,111) <= #CurrDate
AND CONVERT(VARCHAR(10),EndDate, 111) >= #CurrDate
but when the Enddate = #CurrDate the row does not show, but if i make that date just one day higher it gets displayed. Am i doing anything wrong? Any advice will do, thanks.
GetDate() returns date and time, while your conversion to varchar strips away the time part (I'm suspecting that's all it's actually supposed to do). So you would need to do the same conversion for #CurrDate.
If what you want is to simply consider the date only (ignoring the time part), you could use DATEDIFF instead of converting to varchar (see here); example:
DECLARE #CurrDate DATETIME
SET #CurrDate = GETDATE()
SELECT dbo.ProductDetails.PartnerID, dbo.ProductDetails.ProductID,
dbo.Products.ProductName , StartDate, EndDate
FROM dbo.ProductDetails INNER JOIN
dbo.Products ON dbo.ProductDetails.ProductID = dbo.Products.ProductID
-- where StartDate is on the same day or before CurrDate:
WHERE DATEDIFF(day, StartDate, #CurrDate) >= 0 AND
-- and where EndDate is on the same day or after CurrDate:
DATEDIFF(day, EndDate, #CurrDate) <= 0
If you want only DATE comparison, without time use the
cast(CONVERT(varchar, StartDate, 112) as datetime)
I am quite sure that the comparison takes into account the time as well as the date, in which case if the dates are the same but the current time is greater than the time being compared to you won't get that row as a result.
So, what you need to do is just extract the date part and compare those.
GETDATE() gives you date and time
if yours column have only date
then
CONVERT(VARCHAR(10),StartDate,111) <= #CurrDate
can give you unexpected result
remember
19.12.2011 14:41 > 19.12.2011 00:00
If you are using SQL 2008 or later, and wanting to compare only the date, not the time, you can also do:
Cast(StartDate as Date)
(This avoids having to convert to a string.)
