I am using SQL Server 2005.
My Trade_Date column is of datatype datetime.
It has values as: 2/12/2013 11:59:00 PM , 2/13/2013 11:59:00 PM
i.e. different dates with time.
I want to compare date [only date] in where clause.
I am trying with following query:
select *
from foclosing
where CONVERT(varchar(11), Trade_Date) like '2/12/2013 %'
or
select *
from foclosing
where Trade_Date = CONVERT(datetime, '2/12/2013')
but both of these queries are not working.
What can be the issue?
select * from foclosing
where Trade_Date >= '20130212' AND Trade_Date < '20130213'
Use yyyymmdd which is safe for SQL Server
Don't apply functions to columns, then compare (your 1st query)See mistake 2 here: https://www.simple-talk.com/sql/t-sql-programming/ten-common-sql-programming-mistakes/
Don't compare locale-based dates as varchar (your 1st query)
Trade_Date has a time element which is why your 2nd query fails
In summary, a date conversion should not be used for examples like this: datetime is a range

I need to give a select count in a table using the range of two dates, however my dates are in "yyyy-MM-dd" format, and when I execute the select SQL it returns the following error:
Converting a varchar data type to a datetime data type resulted in a value out of range
Here is the query I'm using:
SELECT COUNT(*) AS score
FROM requests
WHERE date_em BETWEEN '2019-04-01' AND '2019-04-30'
Table structure
date_em = DATETIME
Can someone help me?
My preferred method is:
SELECT COUNT(*) AS score
FROM requests
WHERE date_em >= '2019-04-01' AND
date_em < '2019-05-01'
This handles the time component and will make use of an index.
The following also works well in SQL Server:
SELECT COUNT(*) AS score
FROM requests
WHERE CONVERT(date, date_em) BETWEEN '2019-04-01' AND '2019-04-30'
In SQL Server, this will also use an index (if available). However, normally functions on columns preclude the use of an index, so I'm more hesitant about this approach.
have you try this
SELECT COUNT(*) AS score FROM requests WHERE date_em BETWEEN '2019-04-01 00:00' AND '2019-04-30 23:59'
add 00:00 and 23:59 to make it look like a DateTime.
I am working on a project in which dates and times ar stored as a varchar e.g. "30-11-2017,7:30" first date in dd-mm-yyy format and then time separated with a comma. I am trying to filter on it but it is not working correctly kindly guide me how to filter data on date.
select *
from timetrack
where startDateAndTime >= '30-11-2017,7:30'
In attached image records have been shown. When I apply above query it shows no records
You can easily convert your date to SQL datatype datetime uisng parse function, for example select parse('30-11-2017,7:30' as datetime using 'it-IT').
So, in your case, you can apply this function in where clause, so you can easily apply comparison between dates:
select *
from timetrack
where parse(startDateAndTime as datetime using 'it-IT') >= '2017-11-30 07:30:00.000'
Your format is apparently italian :) But you have to specify your own date in the format convertable to datetime, as I have done in above example.
NOTE: parse is available starting with SQL Management Studio 2012.
Unless you are using ISO date format (yyyy-MM-dd HH:mm:ss or close) applying ordering (which inequalities like greater than or equal use) will not work: the date order is disconnected from the string ordering.
You'll need to parse the date and times into a real date time type and then compare to that (details of this depend on which RDBMS you are using).
If, you want to just filter out the date then you could use convert() function for SQL Server
select *
from timetrack
where startDateAndTime >= convert(date, left(#date, 10), 103)
Else convert it to datetime as follow
select *
from timetrack
where startDateAndTime >= convert(datetime, left(#date, 10)+' ' +
reverse(left(reverse(#date), charindex(',', reverse(#date))-1)), 103)
You need the date in a datetime column, Otherwise you can't filter with your current varchar format of your date.
Without changing the existing columns, this can be achieved by making a computed column and making it persisted to optimize performance.
ALTER TABLE test add CstartDateTime
as convert(datetime, substring(startDateAndTime, 7,4)+ substring(startDateAndTime, 4,2)
+ left(startDateAndTime, 2) +' '+ right(startDateAndTime, 5), 112) persisted
Note: this require all rows in the column contains a valid date with the current format
Firstly, you need to check what is the data that is entered in the 'startDateAndTime' column,then you can convert that varchar into date format
If the data in 'startDateAndTime' column has data like '30-11-2017,07:30', you would then have to convert it into date:
SELECT to_date('30-11-2017,07:30','dd-mm-yyyy,hh:mm') from dual; --check this
--Your query:
SELECT to_date(startDateAndTime ,'dd-mm-yyyy,hh:mm') from timetrack;
I have a table with one column dateX formatted as datetime and containing standard dates.
How can I select all records from this table where this dateX equals a certain date, e.g. May 9, 2014 ?
I tried the following, but this returns nothing even if I have several records with this date.
SELECT *
FROM dbo.LogRequests
WHERE (CONVERT(VARCHAR(10), dateX, 101) = '09/05/14')
Edit: In the database the above example looks as follows, using SQL 2012: 2014-05-09 00:00:00.000
The easiest way is to convert to a date:
SELECT *
FROM dbo.LogRequests
WHERE cast(dateX as date) = '2014-05-09';
Often, such expressions preclude the use of an index. However, according to various sources on the web, the above is sargable (meaning it will use an index), such as this and this.
I would be inclined to use the following, just out of habit:
SELECT *
FROM dbo.LogRequests
WHERE dateX >= '2014-05-09' and dateX < '2014-05-10';
For Perfect DateTime Match in SQL Server
SELECT ID FROM [Table Name] WHERE (DateLog between '2017-02-16 **00:00:00.000**' and '2017-12-16 **23:59:00.999**') ORDER BY DateLog DESC
SELECT *
FROM LogRequests
WHERE cast(dateX as date) between '2014-05-09' and '2014-05-10';
This will select all the data between the 2 dates
I using a query where I am selecting some attributes from the table based on a where condition. My where condition is-
date>GetDate();
I have tried this-
SELECT TOP 2 img,name,substring(description,1,80) as
description,Convert(nvarchar,date,106) as date
FROM tbl_test
where date>=Convert(nvarchar,GetDate(),106)
order by date Asc;
This query is running fine but showing different result as compared to a different query of similar kind in which I am not converting the date format.
SELECT TOP 2 img,name,substring(description,1,80) as description,date
FROM tbl_test
where date>=GetDate()
order by date Asc;
Please guide me where I am doing wrong?
Your first query will convert getdate() into nvarchar data type and it will compare date with string while 2nd query will compare 2 dates. So 2nd option is better. Still if you want to convert date into string then check then use 102 format like
WHERE CONVERT(varchar(20),date,102) >= CONVERT(varchar(20), getdate(),102)
For select column you can use format which you want like
SELECT CONVERT(varchar(20),date,106)
Final Query is :
SELECT TOP 2
img,
name,
SUBSTRING(description,1,80) as description,
CONVERT(varchar(20),date,106) as [DisplayDate]
FROM tbl_test
WHERE CONVERT(varchar(20),date,102) >= CONVERT(varchar(20), getdate(),102)
ORDER BY date ASC;
Without convert to varchar, you can cast getdate() to date to remove time part :
SELECT TOP 2
img,
name,
SUBSTRING(description,1,80) as description,
CONVERT(varchar(20),date,106) as [DisplayDate]
FROM tbl_test
WHERE date >= CAST(getdate() as date)
ORDER BY date ASC;
SQL Fiddle Demo
DECLARE #Date Datetime;
SET #Date = GETDATE();
SELECT CONVERT(VARCHAR(12), #Date, 113) AS Date
RESULT
╔══════════════╗
║ Date ║
╠══════════════╣
║ 01 Jan 2014 ║
╚══════════════╝
Edit
as Upendra Chaudhari has explained that when you do comparing column Date with a string =Convert(varchar(20),GetDate(),102),
what is actually happening behind the scenes is Convert(varchar(20),GetDate(),102) returns a string 2014.01.01 but to compare this string with a Datetime column SQL Server does an implicit conversion to compare both values. Sql Server have to have both values in the same datatype to compare them.
Now datatype Datetime has Precedence over nvarchar/varchar datatype so sql server converts the string into datetime datatype which returns something like
SELECT CAST('2014.01.01' AS DATETIME)
Result : 2014-01-01 00:00:00.000
Now in this process of converting your values to string and then back to datetime you have actually lost all the time values in your comparing values. and this is the reason why you are getting unexpected results back.
so make sure whenever you are comparing to have exactly the same datatype on both sides and take control of any data conversions in your code rather then sql server doing datatype conversions for you.
I hope this will explain you why you are getting different results .
You may try:
where date>=CONVERT(VARCHAR(11), GETDATE(), 113)
How do I query DateTime database field within a certain range?
I am using SQL SERVER 2005
Error code below
SELECT *
FROM TABLENAME
WHERE DateTime >= 12/04/2011 12:00:00 AM
AND DateTime <= 25/05/2011 3:53:04 AM
Note that I need to get rows within a certain time range. Example, 10 mins time range.
Currently SQL return with Incorrect syntax near '12'."
You missed single quote sign:
SELECT *
FROM TABLENAME
WHERE DateTime >= '12/04/2011 12:00:00 AM' AND DateTime <= '25/05/2011 3:53:04 AM'
Also, it is recommended to use ISO8601 format YYYY-MM-DDThh:mm:ss.nnn[ Z ], as this one will not depend on your server's local culture.
SELECT *
FROM TABLENAME
WHERE
DateTime >= '2011-04-12T00:00:00.000' AND
DateTime <= '2011-05-25T03:53:04.000'
You need quotes around the string you're trying to pass off as a date, and you can also use BETWEEN here:
SELECT *
FROM TABLENAME
WHERE DateTime BETWEEN '04/12/2011 12:00:00 AM' AND '05/25/2011 3:53:04 AM'
See answer to the following question for examples on how to explicitly convert strings to dates while specifying the format:
Sql Server string to date conversion
This has worked for me in both SQL Server 2005 and 2008:
SELECT * from TABLE
WHERE FIELDNAME > {ts '2013-02-01 15:00:00.001'}
AND FIELDNAME < {ts '2013-08-05 00:00:00.000'}
You can execute below code
SELECT Time FROM [TableName] where DATEPART(YYYY,[Time])='2018' and DATEPART(MM,[Time])='06' and DATEPART(DD,[Time])='14
SELECT *
FROM TABLENAME
WHERE [DateTime] >= '2011-04-12 12:00:00 AM'
AND [DateTime] <= '2011-05-25 3:35:04 AM'
If this doesn't work, please script out your table and post it here. this will help us get you the correct answer quickly.

Others have already said that date literals in SQL Server require being surrounded with single quotes, but I wanted to add that you can solve your month/day mixup problem two ways (that is, the problem where 25 is seen as the month and 5 the day) :
Use an explicit Convert(datetime, 'datevalue', style) where style is one of the numeric style codes, see Cast and Convert. The style parameter isn't just for converting dates to strings but also for determining how strings are parsed to dates.
Use a region-independent format for dates stored as strings. The one I use is 'yyyymmdd hh:mm:ss', or consider ISO format, yyyy-mm-ddThh:mi:ss.mmm. Based on experimentation, there are NO other language-invariant format string. (Though I think you can include time zone at the end, see the above link).
if you have a type of datetime and you want to check between dates only ,,,use cast to select between two dates ....
example...
... where cast( Datetime as date) >= cast( Datetime as date) AND cast( Datetime as date) <= cast( Datetime as date)
