I have some data in the following date format.
'27-SEP-97' i.e DD-MON-YY
Now I want to convert this to YYYYMMDD. I am using the following script to convert this.
TO_CHAR(TO_DATE(CHD_DATE_FIRST_ACT,'DD-MON-YY'),'YYYYMMDD')
but this is giving me the following output.
20970927
I want this data to be in YYYYMMDD format, such that the output looks like this- 19970927
If '27-SEP-97' is a string (which is what your words suggest), then such a combination of TO_this and TO_that might do the job:
SQL> with test as (select '27-SEP-97' datum from dual)
2 select to_char(to_date(datum, 'dd-mon-rr', 'nls_date_language = english'), 'yyyymmdd') result
3 from test;
RESULT
--------------------------------------------------------------------------------
19970927
SQL>
--USE RR instead of YY in your query.
select TO_CHAR(TO_DATE('27-SEP-97','DD-MON-RR'),'YYYYMMDD') from dual;
You can make use of mysql replace and str_to_date functions
replace takes 3 arguments as show below
replace(string,find_string,replace_with)
you should simply replace - with a blank string
if your str is '27-SEP-97' to get the output as 19970927 execute the following in mysql
select replace(str_to_date('27-SEP-97','%d-%b-%Y'),'-','') as date;
output
+----------+
| date |
+----------+
| 19970927 |
+----------+
%b is used to mention abbreviated month name

I've a column sample_date in form of string as 200912301111230000000000 (UTC Time).How can I convert it from string to datetime in form of yyyymmdd using SQL select statement?
As you only want yyyymmdd, which is the first 8 chacters of your string, it is enough to simply use LEFT
I added the ST_TO_DATE so that you can see hw a conversionto a Date column could work
SELECT LEFT('200912301111230000000000',8),STR_TO_DATE(LEFT('200912301111230000000000',8),'%Y%m%d')
LEFT('200912301111230000000000',8) | STR_TO_DATE(LEFT('200912301111230000000000',8),'%Y%m%d')
:--------------------------------- | :-------------------------------------------------------
20091230 | 2009-12-30
db<>fiddle here
So it would loke like this
SELECT LEFT(Your_Column,8) FROM Your_Table
I have a table were the date required to be fetched is of type character. I tried using CONVERT function but it isn't working.
The query works fine in postgres but not in db2.
select * FROM abc
where (to_date(from_month_year,'MM/YYYY') between '01/04/2017' and '01/04/2018')
OR (to_date(to_month_year,'MM/YYYY')between '01/04/2017' and '01/04/2018')
union
select * FROM abc
where ('01/04/2017' between to_date(from_month_year,'MM/YYYY')
and to_date(to_month_year,'MM/YYYY'))
OR ('01/04/2018' between to_date(from_month_year,'MM/YYYY')
and to_date(to_month_year,'MM/YYYY'))
try to use Date Format str_to_date.
DATE_FORMAT(STR_TO_DATE(StartDate,'%d-%m-%Y'), '%m-%Y')
I want to convert a timestamp in MySQL to a date.
I would like to format the user.registration field into the text file as a yyyy-mm-dd.
Here is my SQL:
$sql = requestSQL("SELECT user.email,
info.name,
FROM_UNIXTIME(user.registration),
info.news
FROM user, info
WHERE user.id = info.id ", "export members");
I also tried the date conversion with:
DATE_FORMAT(user.registration, '%d/%m/%Y')
DATE(user.registration)
I echo the result before to write the text file and I get :
email1;name1;DATE_FORMAT(user.registration, '%d/%m/%Y');news1
email2;name2;news2
How can I convert that field to date?
DATE_FORMAT(FROM_UNIXTIME(`user.registration`), '%e %b %Y') AS 'date_formatted'
To just get a date you can cast it
cast(user.registration as date)
and to get a specific format use date_format
date_format(registration, '%Y-%m-%d')

Convert timestamp to date in MYSQL
Make the table with an integer timestamp:
mysql> create table foo(id INT, mytimestamp INT(11));
Query OK, 0 rows affected (0.02 sec)
Insert some values
mysql> insert into foo values(1, 1381262848);
Query OK, 1 row affected (0.01 sec)
Take a look
mysql> select * from foo;
+------+-------------+
| id | mytimestamp |
+------+-------------+
| 1 | 1381262848 |
+------+-------------+
1 row in set (0.00 sec)
Convert the number to a timestamp:
mysql> select id, from_unixtime(mytimestamp) from foo;
+------+----------------------------+
| id | from_unixtime(mytimestamp) |
+------+----------------------------+
| 1 | 2013-10-08 16:07:28 |
+------+----------------------------+
1 row in set (0.00 sec)
Convert it into a readable format:
mysql> select id, from_unixtime(mytimestamp, '%Y %D %M %H:%i:%s') from foo;
+------+-------------------------------------------------+
| id | from_unixtime(mytimestamp, '%Y %D %M %H:%i:%s') |
+------+-------------------------------------------------+
| 1 | 2013 8th October 04:07:28 |
+------+-------------------------------------------------+
1 row in set (0.00 sec)
If the registration field is indeed of type TIMESTAMP you should be able to just do:
$sql = "SELECT user.email,
info.name,
DATE(user.registration),
info.news
FROM user,
info
WHERE user.id = info.id ";
and the registration should be showing as yyyy-mm-dd
FROM_UNIXTIME(unix_timestamp, [format]) is all you need
FROM_UNIXTIME(user.registration, '%Y-%m-%d') AS 'date_formatted'
FROM_UNIXTIME gets a number value and transforms it to a DATE object,
or if given a format string, it returns it as a string.
The older solution was to get the initial date object and format it with a second function DATE_FORMAT... but this is no longer necessary
Just use mysql's DATE function:
mysql> select DATE(mytimestamp) from foo;
You should convert timestamp to date.
select FROM_UNIXTIME(user.registration, '%Y-%m-%d %H:%i:%s') AS 'date_formatted'
FROM_UNIXTIME
If you are getting the query in your output you need to show us the code that actually echos the result. Can you post the code that calls requeteSQL?
For example, if you have used single quotes in php, it will print the variable name, not the value
echo 'foo is $foo'; // foo is $foo
This sounds exactly like your problem and I am positive this is the cause.
Also, try removing the # symbol to see if that helps by giving you more infromation.
so that
$SQL_result = #mysql_query($SQL_requete); // run the query
becomes
$SQL_result = mysql_query($SQL_requete); // run the query
This will stop any error suppression if the query is throwing an error.
I did it with the 'date' function as described in here :
(SELECT count(*) as the-counts,(date(timestamp)) as the-timestamps FROM `user_data` WHERE 1 group BY the-timestamps)
If you want to change the datatype of the column, you can simply convert first from TIMESTAMP to INT:
ALTER TABLE table_name MODIFY column_name INT;
And then INT to DATE:
ALTER TABLE table_name MODIFY column_name DATE;
But, if you didn't mean to change a column, but wanted SELECT only, then you can use date() function:
SELECT date(your_timestamp_column) FROM your_table;
I want to convert a record 1580707260
Usually, I am using online timestamp converter
Want to showcase it in the query result
Please try this
DATE_FORMAT(FROM_UNIXTIME(field name from table), '%e %b %Y')
AS 'display name for result'
Try:
SELECT strftime("%Y-%d-%m", col_name, 'unixepoch') AS col_name
It will format timestamp in milliseconds to yyyy-mm-dd string.
You can use this command FROM_UNIXTIME(unix_timestamp, [format]); but sometimes timestamp is in a long value that you have to remove 3 last values to 0.
for instance you use this command from_unixtime(e.EVENT_TIME/1000);
this way solve my problem.
I have a list of file paths and dates stored in a database:
path | date
_____________________________|___________
C:\folder\file1 %Y-%m-%d.csv | 2016-09-14
C:\folder\file2_%M %d %Y.csv | 2016-09-13
C:\folder\file3 %y%m%d.csv | 2016-08-31
The dates in the file paths are according to the STR_TO_DATE format convention.
The dates will change everyday.
I need to write a SELECT query that will return:
result
_________________________________
C:\folder\file1 2016-09-14.csv
C:\folder\file2_Sep 14 2016.csv
C:\folder\file3 160831.csv
I don't want to end up writing a never-ending REPLACE query with all the possible scenarios:
REPLACE(... REPLACE(REPLACE(path,'%Y',YEAR(date)),'%d',DAY(date))...)
Is there a way to do this with a MySQL built-in function?
You want DATE_FORMAT() here. It should replace format strings it recognizes with their values and ignore everything else.
SELECT DATE_FORMAT(date, path) AS result;
NOTE: %M Will give the full month ("September"), for the abbreviated month ("Sept") use %b.
