I am using a stored procedure to write the date and time in a file. Also, I have scheduled my procedure to 1 AM daily.
My code to get the date and time is
select to_char(CURRENT_TIMESTAMP,'DDMMYYYY/HH:MI:SS') from dual;
But, the displayed date was the previous day's date. Will sysdate() works in this place correctly?

I try to insert the created field in my_table. The created field has a datetime type. In my_table the field my_created has a date format. So I try to TRUNC the created field. However I'm getting the error ORA-01830: date format picture ends before converting entire input stringwhile inserting the truncated value. It seems, that the time is still there but is reset to 00:00. how can I get only the date without time? It happens only in perl. I'm getting only date in toad.
Very simplified code looks like:
my $SQL="SELECT
TRUNC(CREATED),
FROM
DBA_OBJECTS";
my $sth = $db->prepare($SQL);
$sth->execute();
my $date = $sth->fetchrow();
$SQL = "INSERT INTO MY_TABLE
(MY_CREATED)
VALUES (?)";
my $stmt = $dbh_master->prepare($SQL);
$stmt->execute($date);
EDIT:
I found an ugly workaround and I'm executing it like this:
$stmt->execute(substr($date, 0, 10));
However maybe someone has a nicer solution.
How can I get only the date without time?
In Oracle, a DATE is a binary data type that is composed of 7 bytes representing: century, year-of-century, month, day, hour, minute and second. It ALWAYS has those binary components so if you want an Oracle DATE data type then you cannot get it without a time.
The Oracle DATE data type was released with Oracle version 2 in 1979 and predates the ANSI/ISO standard (of 1986, where a DATE does not have a time component) and Oracle has maintained backwards compatibility with their previous data types rather than adopting the ANSI standard.
If you use the TRUNC(date_value, format_model) function then it will set the binary components of the DATE, up to the specified format model, to the minimum (0 for hours, minutes and seconds, 1 for days and months) but it will NOT give you a data type that does not have a time component.
It happens only in perl. I'm getting only date in toad.
No, you are getting the entire 7 byte binary value in Toad; however, the user interface is only choosing to show you the date component. There should be a setting in the preferences that can set the date format in Toad which will let you see the entire date-time components.
Oracle SQL/Plus and SQL Developer use the NLS_DATE_FORMAT session parameter and Toad may also be able to use that.
If you want to get the value as a DATE then it will always have a time component (even if you set that time component to zeros using TRUNC).
If you want to get the date so that it is formatted in a way without a time component then you need to convert it to another data type and can use TO_CHAR to format it as a string:
SELECT TO_CHAR(CREATED, 'YYYY-MM-DD')
FROM DBA_OBJECTS
But then you will be returning a (formatted) string and not a DATE data type.
currently have this as a trigger when-create-record
:Transaction.Transaction_Date := sysdate;
it gets me the date but not the current time (10-APR-2020 00:00:00) and it displays on my display item before i execute query. is there a way to show the time when i execute?
I have a column name 'Cos_Date' with value like 14APR2017:00:00:00.
However, for a new column name 'Arrival_Date', I would like to keep the date information but omit time, and keep the data type as Date but not Character. Ex, 14APR2017.
I have tried:
select TO_CHAR(Cos_Date, 'DD-MON-YYYY') ARRIVAL_DATE
But it will delete time information, but data type turns to Character.
I search on this site, and tried both:
select TO_DATE(TO_CHAR(Cos_Date, 'DD-MON-YYYY'), 'DD-MON-YYYY') ARRIVAL_DATE
and:
select TRUNC(Cos_Date) ARRIVAL_DATE
But it will not omit time information.
Can I try something else?
Thank you!
You can't "omit" the time portion of a DATE column in Oracle. The DATE data type always contains a time component. If you don't want to see the time, don't display it, e.g.,
SELECT TO_CHAR(TRUNC(Cos_Date),'DD-MON-YYYY') FROM dual;
In Oracle there is no date data type that has only a year-month-day component.
The DATE data type is stored internally as 7- or 8-bytes which always has year (2-bytes), month (1-byte), day (1-byte), hour (1-byte), minute (1-byte) and second (1-byte).
The TIMESTAMP data type also has fractional seconds (and can also have a time zone).
Can I try something else?
No, you either use a VARCHAR2 string or use a DATE or TIMESTAMP and accept that it has a time component.
Selecting date values without time:
SELECT date_col
FROM table
WHERE TO_CHAR (date_col, 'HH24:MI:SS') = '00:00:00';
I have a need to pull in via FTP only files from dates I haven't pulled data. The data pulls happen nightly, but occasionally there is an issue and a night gets skipped, and it will be picked up the following night.
I located a query on StackOverflow which addressed most of my problem. However, I'm left with an uncomfortable solution and a lingering question.
I have a table with data from each file downloaded. The crux of the data I'm using for this example is EXTRACT_DATE. The file format is filename_20160809.csv, as an example. Uses the 4-digit year, 2-digit month and 2-digit day to make unique. The FTP location has thousands of files, and I only want to grab the new, based on this date.
First, I get the latest EXTRACT_DATE from my table as such
SELECT MAX(EXTRACT_DATE) INTO checkDate FROM FILE_DETAILS;
I had attempted to do this in a single query, but couldn't work it, and finally attempted to create a variable, checkDate, and use this variable in a subsequent query to obtain my list. However, having two queries in a single script is not allowed, or I haven't found a way to do it. So my primary issue is to return the value of the latest date. Then call a new query or procedure with the value incorporated in to obtain my list, with this query
SELECT TO_DATE(checkDate, 'MM/DD/YYYY') + rownum AS EXTRACT_DATES
FROM ALL_OBJECTS
WHERE TO_DATE(checkDate, 'MM/DD/YYYY') + rownum <= TO_DATE(SYSDATE, 'DD-MM-YY');
This solution is messy and uncomfortable, I would prefer a single query to get back my results, rather then 2 scripts or a script and a procedure.
The lingering question, the result from the query returns dates in the mm/dd/yyyy format; 8/9/2016. I adjusted the TO_DATE to match.
Initially, it was set to return as YYYY-MM-DD; 2016-08-09.
However, it wouldn't return in this format. It would only come back as 8/9/2016, regardless of the TO_DATE formatting used. I don't understand why the date is coming back in this format.
SELECT TO_DATE('2-AUG-2016', 'DD-MON-RR') + rownum AS EXTRACT_DATES
FROM ALL_OBJECTS
WHERE TO_DATE('2-AUG-2016', 'DD-MON-RR') + rownum <= TO_DATE(SYSDATE, 'DD-MM-YY');
EXTRACT_DATES
8/3/2016
8/4/2016
8/5/2016
8/6/2016
8/7/2016
8/8/2016
8/9/2016
NLS_DATE_FORMAT is set to DD-MON-RR, with American as NLS_DATE_LANGUAGE.
I am working (or fixing bugs) on an application which was developed in VS 2005 C#. The application saves data to a SQL server 2005. One of insert SQL statement tries to insert a time-stamp value to a field with GetDate() TSQL function as date time value.
Insert into table1 (field1, ... fieldDt) values ('value1', ... GetDate());
The reason to use GetDate() function is that the SQL server may be at a remove site, and the date time may be in a difference time zone. Therefore, GetDate() will always get a date from the server. As the function can be verified in SQL Management Studio, this is what I get:
SELECT GetDate(), LEN(GetDate());
-- 2010-06-10 14:04:48.293 19
One thing I realize is that the length is not up to the milliseconds, i.e., 19 is actually for '2010-06-10 14:04:48'. Anyway, the issue I have right now is that after the insert, the fieldDt actually has a date time value up to minutes, for example, '2010-06-10 14:04:00'. I am not sure why. I don't have permission to update or change the table with a trigger to update the field.
My question is that how I can use a INSERT T-SQL to add a new row with a date time value ( SQL server's local date time) with a precision up to milliseconds?
Check your table. My guess is that the FieldDT column has a data type of SmallDateTime which stores date and time, but with a precision to the nearest minute. If my guess is correct, you will not be able to store seconds or milliseconds unless you change the data type of the column.
I would guess that you are not storing the GetDate() value in a DateTime field. If you store the value in a datetime field you will get the maximum precision allowed by the DateTime type. Additionally, DateTime is a binary type (a double actually) so 19 means 19 bytes, not 19 characters.
Try to create a simple table with a Datetime field like this
CREATE TABLE [dbo].[DateTable](
[DateField] [datetime] NOT NULL
)
And add a date with
insert into datetable (datefield) values(getdate())
When you execute a select you will get back a value including milliseconds. The following query
select * from datetable
returns
2010-06-11 00:38:46.660
Maybe this would work instead of getdate -
SYSDATETIME()

As you're on SQL 2005, don't forget the getutcdate() function to ensure that, regardless of where your servers are actually located, you have a constant time reference.
Imagine, you have the server in the UK in winter (i.e. GMT+0), and save a record at 10:30am. You then cut over to a SQL server hosted in California (GMT+8) and 8 hours later save another record.
Using getdate(), both saves record the same time "10:30:00". Using getutcdate(), the first save records at "10:30:00", the second save records "18:30:00".
Not really answering the question, but important in your circumstances.
You can use like this in procedure and If there is no procedure use only getdate().
insert into [dbo].[Tbl_User] (UserId,Uvendoremail,UAddress,Ddob,DMobile,
DEmail,DPassword,DAddress,CreatedDate) values (#userid,#vendoremail#address,#dob,#mobile,#email,#dpassword,#daddress,getdate())
