I have a table in SQL Server created like this:
CREATE TABLE nombres
(
nombre varchar (200) not null,
fecha_nac char (10) not null,
fecha_alta char (10) not null,
)
I created a stored procedure to fill the table quickly. The next step is "formatting" the dates made into date format. I saw that I can use
SELECT CONVERT(datetime, 'a string', 100)
In this case I want use my column as parameter like this
SELECT CONVERT (datetime, select fecha_nac from nombres, 100)
but I get an error.
I will be thankful if I get any help
DECLARE #site_value INT;
SET #site_value = 1;
WHILE #site_value <= (SELECT COUNT(nombre) FROM nombres)
BEGIN
WITH MyCte AS
(
SELECT fecha_nac,number= ROW_NUMBER() OVER (ORDER BY dbo.nombres.fecha_nac)
from dbo.nombres
)
SELECT convert(datetime,(SELECT MyCte.fecha_nac from MyCte WHERE number=#site_value), 101)
SET #site_value = #site_value + 1;
END;
With the date format you have, (mm-yyyy-dd), you can do some string manipulation to get it to dd-mm-yyyy and then it can be parsed as a DATE with format 103.
WITH cte AS (
SELECT '11-1994-27' fecha_nac
)
SELECT
CONVERT(DATE, SUBSTRING(fecha_nac, 9, 2) + '-' + SUBSTRING(fecha_nac, 0, 8), 103)
FROM cte;
-- 1994-11-27
Your fecha_alta format is easier, it can be parsed right away with format 102.
WITH cte AS (
SELECT '2012-1-12' fecha_alta UNION ALL
SELECT '1994-4-5'
)
SELECT
CONVERT(DATE, fecha_alta, 102)
FROM cte;
-- 2012-01-12
-- 1994-04-05

Two Column in table tblpress
Date Time
20160307 120949
20160307 133427
Need to be select below the format:
07-03-2016 12:09:49
07-03-2016 13:34 27
or
03-March-2016 12:09: 49 PM
03-March-2016 01:34: 27 PM
You can try below
select format(cast([Date] as date),'dd-MMMM-yyyy') as [Date],
TIMEFROMPARTS(LEFT([Time],2), SUBSTRING([Time],3,2), RIGHT([Time],2), 0,0) as [Time]
I think CAST/CONVERT will help you:
SELECT
CAST('20160307' AS date),
CAST(STUFF(STUFF('120949',3,0,':'),6,0,':') AS time)
And convert for out:
SELECT
CONVERT(varchar(20),NormalDate,105) OutDate, -- Italian style
CONVERT(varchar(20),NormalTime,108) OutTime -- hh:mi:ss
FROM
(
SELECT
CAST([Date] AS date) NormalDate,
CAST(STUFF(STUFF([Time],3,0,':'),6,0,':') AS time) NormalTime
FROM YourTable
) q
CAST and CONVERT (Transact-SQL)
And you can use FORMAT (Transact-SQL)
SELECT
FORMAT(GETDATE(),'dd-MM-yyyy'),
FORMAT(GETDATE(),'HH:mm:ss')
Best way to do it is to create a function :
create FUNCTION [dbo].[udfGetDateTimeFromInteger]
(
#intDate int,
#intTime int
)
RETURNS datetime
AS BEGIN
-- Declare the return variable here
DECLARE #DT_datetime datetime = NULL,
#str_date varchar(11),
#str_time varchar(8)
if(#intDate is not null and #intDate > 0)
begin
select #str_date = CAST( cast(#intDate as varchar(8)) AS date)
if #intTime=0
select #str_time ='000000'
else
select #str_time = right('0'+CONVERT(varchar(11),#intTime),6)
select #str_time =
SUBSTRING(#str_time,1,2)+':'+SUBSTRING(#str_time,3,2)+':'+SUBSTRING(#str_time,5,2)
select #DT_datetime = CAST(#str_date+' '+#str_time as datetime)
end
-- Return the result of the function
RETURN #DT_datetime
END
and then call it in select like :
declare #next_run_date int, #next_run_time int
select #next_run_date = 20160307
select #next_run_time = 130949
SELECT #next_run_date inputdate,
#next_run_time inputtime,
dbo.udfGetDateTimeFromInteger(#next_run_date, #next_run_time) outputdatetime
Output will be like :
inputdate inputtime outputdatetime
20160307 130949 2016-03-07 13:09:49.000
You said those are numbers, right? You can use datetimefromparts (or datetime2fromparts). ie:
select
datetimefromparts(
[date]/10000,
[date]%10000/100,
[date]%100,
[time]/10000,
[time]%10000/100,
[time]%100,0)
from tblpress;
DB Fiddle demo
Note that naming fields like that and also storing date and time like that is a bad idea.
I later noticed it was char fields:
select
cast([date] as datetime) +
cast(stuff(stuff([time],5,0,':'),3,0,':') as datetime)
from tblpress;
How to convert date/time from 20150323153528 to 2015-03-23 15:35:28.000. I need this to filter based on the getdate(). Thanks in advance.
Select * from table
Where 20150323153528 > GETDATE() - 7
Statement to convert date to your requirement
DECLARE #Date varchar(20) = '20150323153528'
Select * from table Where
CONVERT(DATETIME, CONVERT(CHAR(8), #Date), 121) + ' ' + stuff(stuff(right('000000' + cast(#Date as varchar),6),5,0,':'),3,0,':') as DATETIME > GETDATE() - 7
In MS SQL you could use
DECLARE #Date varchar(20) = '20150323153528'
Select * from table Where CAST(convert(varchar,#Date) as datetime) > GETDATE() - 7
Please read this page.
SELECT convert(varchar, getdate(), 120) — yyyy-mm-dd hh:mm:ss(24h)
Note: I assume this is a Microsoft SQL Server environment using T-SQL:
The formatting of date / datetime values is not a concern of T-SQL. You should do that in your presentation-layer (i.e. your frontend code).
If you have date/time values represented as integers of the form 20150323153528 then you cannot use them in T-SQL. You need to convert them to strings (preferably in ISO-8601 format) for SQL Server to successfully internally convert them to datetime (or datetimeoffset) values which can then be compared with other datetime values.
I suggest performing the conversion in your application code before you send it to SQL, as a datetime-typed parameter value, like so:
Int32 weirdDateValue = 20150323153528;
String s = weirdDateValue.ToString( CultureInfo.InvariantCulture );
String dtValueAsIso8601 = String.Format("{0}-{1}-{2} {3}:{4}:{5}.{6}",
s.Substring(0, 4), s.Substring(4, 2), s.Substring(6, 2),
s.Substring(8, 2), s.Substring(10, 2), s.Substring(12, 2), s.Substring(14)
);
DateTime dtValue = DateTime.ParseExact( dtValueAsIso8601, "yyyy-MM-dd HH:mm:ss.fff" );
cmd.Parameters.Add("#dtValue", SqlDbType.DateTime).Value = dtValue;
In T-SQL the process is pretty much the same, except using MID - note that MID uses 1-based character indexes instead of 0-based:
DECLARE #input int = 20150323153528
DECLARE #s varchar( 14 ) = CONVERT( #input, nvarchar(14) )
DECLARE #dtStr varchar( 24 ) = MID( #s, 1, 2 ) + '-' + MID( #s, 3, 2 ) + '-' + MID( #s, 5, 2 ) + ' ' + -- etc...
DECLARE #dt datetime = CONVERT( #dtStr, datetime )
SELECT
*
FROM
[table]
WHERE
#dt > GETDATE() - 7
If the integer values are stored in an actual column instead of a parameter you'll need to convert the logic into a scalar UDF which performs the conversion. I strongly suggest you change the table's design to add a strongly-typed datetime column and permanently store the value there, and then drop the datetime-as-int column:
CREATE FUNCTION ConvertIntDateIntoDateTime(#dateAsInt int) RETURNS datetime AS
BEGIN
-- same code as above minus the SELECT statement
RETURN #dt
END
Used in an inner subquery to allow the data to be accessed in WHERE statements, like so:
SELECT
*
FROM
(
SELECT
*,
dbo.ConvertIntDateIntoDateTime( someDateColumn ) AS someDateColumn2
FROM
[table]
) AS FixedTable
WHERE
FixedTable.someDateColumn2 > GETDATE() - 7
I have 2 columns in a table of varchar datatype.
date and type are the column names in table.
the data present in the table looks like this
date time
20090610 132713
20090610 132734
i need ms sql server query to concatenate these 2 columns data and display as datetime format.
Note :
1. the datatype of those 2 columns cannot be changed now.
2. i tried
select convert(datetime,date + time)
it says "Conversion failed when converting date and/or time from character string."
Suggest the possible solution.
This will return a datetime. The bottom line is to be replaced by your table
select convert(datetime,date,112)+
coalesce(stuff(stuff(rtrim(time), 5,0,':'), 3,0,':'), '') newdate
from
(VALUES ('20090610','132713'),('20090610', '132734'),('20090610', ' ')) yourtable(date,time)
Result:
newdate
2009-06-10 13:27:13.000
2009-06-10 13:27:34.000
2009-06-10 00:00:00.000
You can get it using
SELECT
convert(varchar, convert(datetime, date), 111)
+ ' ' + substring(time, 1, 2)
+ ':' + substring(time, 3, 2)
+ ':' + substring(time, 5, 2)
CREATE TABLE #Table
(
[date] VARCHAR(100),
[time] VARCHAR(100)
)
INSERT INTO #Table VALUES
('20090610','132713'),
('20090610','132734')
;WITH Bits_CTE
AS
(
SELECT
[Date],
[Time],
[hrs] = CONVERT(INT,SUBSTRING([Time], 1, 2)),
[mns] = CONVERT(INT,SUBSTRING([Time], 3, 2)),
[secs] = CONVERT(INT,SUBSTRING([Time], 5, 2))
FROM #Table
)
SELECT
[Date],
[Time],
DATEADD(HOUR,[hrs],
DATEADD(MINUTE,[mns],
DATEADD(SECOND,[secs],[Date])))
FROM Bits_CTE
CREATE FUNCTION [dbo].[DateTimeAdd]

#datepart date,
#timepart time
)
RETURNS datetime2
AS
BEGIN
RETURN DATEADD(dd, DATEDIFF(dd, 0, #datepart), CAST(#timepart AS datetime2));
END
Sorry - Missed the bit in your question about storing the date and time as varchars. You would therefore still need to convert these data itemsbefore using this function.
I have datetime values stored in a field as strings. They are stored as strings because that's how they come across the wire and the raw values are used in other places.
For reporting, I want to convert the custom format string (yyyymmddhhmm) to a datetime field in a view. My reports will use the view and work with real datetime values. This will make queries involving date ranges much easier.
How do I perform this conversion? I created the view but can't find a way to convert the string to a datetime.
Thanks!
Update 1 -
Here's the SQL I have so far. When I try to execute, I get a conversion error "Conversion failed when converting datetime from character string."
How do I handle nulls and datetime strings that are missing the time portion (just yyyymmdd)?
SELECT
dbo.PV1_B.PV1_F44_C1 AS ArrivalDT,
cast(substring(dbo.PV1_B.PV1_F44_C1, 1, 8)+' '+substring(dbo.PV1_B.PV1_F44_C1, 9, 2)+':'+substring(dbo.PV1_B.PV1_F44_C1, 11, 2) as datetime) AS ArrDT,
dbo.MSH_A.MSH_F9_C2 AS MessageType,
dbo.PID_A.PID_F3_C1 AS PRC,
dbo.PID_A.PID_F5_C1 AS LastName,
dbo.PID_A.PID_F5_C2 AS FirstName,
dbo.PID_A.PID_F5_C3 AS MiddleInitial,
dbo.PV1_A.PV1_F2_C1 AS Score,
dbo.MSH_A.MessageID AS MessageId
FROM dbo.MSH_A
INNER JOIN dbo.PID_A ON dbo.MSH_A.MessageID = dbo.PID_A.MessageID
INNER JOIN dbo.PV1_A ON dbo.MSH_A.MessageID = dbo.PV1_A.MessageID
INNER JOIN dbo.PV1_B ON dbo.MSH_A.MessageID = dbo.PV1_B.MessageID
According to here, there's no out-of-the-box CONVERT to get from your yyyymmddhhmm format to datetime.
Your strategy will be parsing the string to one of the formats provided on the documentation, then convert it.
declare #S varchar(12)
set #S = '201107062114'
select cast(substring(#S, 1, 8)+' '+substring(#S, 9, 2)+':'+substring(#S, 11, 2) as datetime)
Result:
2011-07-06 21:14:00.000'
This first changes your date string to 20110706 21:14. Date format yyyymmdd as a string is safe to convert to datetime in SQL Server regardless of SET DATEFORMAT setting.
Edit:
declare #T table(S varchar(12))
insert into #T values('201107062114')
insert into #T values('20110706')
insert into #T values(null)
select
case len(S)
when 12 then cast(substring(S, 1, 8)+' '+substring(S, 9, 2)+':'+substring(S, 11, 2) as datetime)
when 8 then cast(S as datetime)
end
from #T
Result:
2011-07-06 21:14:00.000
2011-07-06 00:00:00.000
NULL
You can use CAST or CONVERT.
Example from the site:
G. Using CAST and CONVERT with
datetime data
The following example displays the
current date and time, uses CAST to
change the current date and time to a
character data type, and then uses
CONVERT display the date and time in
the ISO 8901 format.
SELECT
GETDATE() AS UnconvertedDateTime,
CAST(GETDATE() AS nvarchar(30)) AS UsingCast,
CONVERT(nvarchar(30), GETDATE(), 126) AS UsingConvertTo_ISO8601;
GO
Here is the result set.

Generally, you can use this code:
SELECT convert(datetime,'20110706',112)
If you need to force SQL Server to use a custom format string, use the following code:
SET DATEFORMAT ymd
SELECT convert(datetime,'20110706')
A one liner:
declare #datestring varchar(255)
set #datestring = '201102281723'
select convert(datetime, stuff(stuff(#datestring,9,0,' '),12,0,':') , 112 )
Result:
2011-02-28 17:23:00.000
DECLARE #d VARCHAR(12);
SET #d = '201101011235';
SELECT CONVERT(SMALLDATETIME, STUFF(STUFF(#d,9,0,' '),12,0,':'));
Note that by storing date/time data using an inappropriate data type, you cannot prevent bad data from ending up in here. So it might be safer to do this:
WITH x(d) AS
(
SELECT d = '201101011235'
UNION SELECT '201101011267' -- not valid
UNION SELECT NULL -- NULL
UNION SELECT '20110101' -- yyyymmdd only
),
y(d, dt) AS
(
SELECT d,
dt = STUFF(STUFF(LEFT(d+'000000',12),9,0,' '),12,0,':')
FROM x
)
SELECT CONVERT(SMALLDATETIME, dt), ''
FROM y
WHERE ISDATE(dt) = 1 OR d IS NULL
UNION
SELECT NULL, d
FROM y
WHERE ISDATE(dt) = 0 AND d IS NOT NULL;
DECLARE #test varchar(100) = '201104050800'
DECLARE #dt smalldatetime
SELECT #dt = SUBSTRING(#test, 5, 2)
+ '/' + SUBSTRING(#test, 7, 2) + '/'
+ SUBSTRING(#test, 1, 4) + ' ' + SUBSTRING(#test, 9, 2)
+ ':' + SUBSTRING(#test, 11, 2)
SELECT #dt
Output:
2011-04-05 08:00:00
I have a column offset in db as varchar(50) which contains a value such as 05:30:00 or -2:15:00.
I need to add or subtract this value from another column which is a DATETIME datatype as 2011-07-22 14:51:00.
try something like -
select convert(datetime, '05:30:00') + GETDATE()
What's your database platform?
On MS SQL you'd do it like this...
-- Create some test data
create table dbo.MyData (
Adjustment varchar(50) NOT NULL,
BaseDate datetime NOT NULL
) on [primary]
go
insert into dbo.MyData ( Adjustment, BaseDate ) values ( '05:30:00', cast('2011-07-22 14:51:00' as datetime) )
insert into dbo.MyData ( Adjustment, BaseDate ) values ( '-2:15:00', cast('2011-06-12 10:27:30' as datetime) )
go
-- Perform the adjustment
select
c.Adjustment,
c.BaseDate,
c.AdjSecs,
dateadd(s, c.AdjSecs, c.BaseDate ) as AdjustedDate
from (
select
case
when left( Adjustment, 1 ) = '-' then -1 * datediff(s, 0, right( Adjustment, len(Adjustment) - 1 ))
else datediff(s, 0, right( Adjustment, len(Adjustment) - 1 ))
end as AdjSecs,
Adjustment,
BaseDate
from dbo.MyData
) as c
Note, this takes account of negative adjustment periods too.
Replace getdate() function with your date column
DECLARE #mytime AS VARCHAR(10)
SET #mytime = '2:15:00'
SELECT DATEADD(
s
,CASE
WHEN SUBSTRING(#mytime,1,1)='-'
THEN -DATEDIFF(s,0, SUBSTRING(#mytime,2,LEN(#mytime)-1)
ELSE DATEDIFF(s,0, #mytime)
END
,GETDATE()
)
