I've view named Sales View
select * from SalesView;
I want to fetch records from SalesView having order_date 9-OCT-2019.
Value for Order date is supplied from GUI in format DD-MM-YYYY.
I tried,
select *
from salesView
where str_to_date(order_date,'%d-%m-%Y') = str_to_date('09-10-2019','%d-%m-%Y')
order by oID;
I've also tried date_format() instead of str_to_date(), but It is returning nothing.
Check your where clause
where str_to_date(order_date,'%d-%m-%Y') = str_to_date('09-10-2019','%d-%m-%Y')
Replace order_date's format with the format in which database stored it. YYYY-MM-DD
where str_to_date(order_date,'%Y-%m-%d') = str_to_date('09-10-2019','%d-%m-%Y')

I want to sort a date-of-birth column in a table which has date stored in format of %m/%d/%Y . When I use order by , the column values are being treated and sorted as string and not date. I have tried UNIX_TIMESTAMP() function but it also seems to be not working. What are the possible solutions ?
Use STR_TO_DATE() Function
SELECT * FROM yourtable
ORDER BY STR_TO_DATE(DueDate,'%m/%d/%Y ') DESC
I'm querying
SELECT * FROM tempLog WHERE date BETWEEN '23-03-2017' AND '02-04-2017'
and the result is null. How to fix this. But
SELECT * FROM tempLog WHERE date BETWEEN '23-03-2017' AND '30-03-2017'
giving me the correct result.
Note:- tempLog is the table name.
You should store dates in date format or atleast correctly formatted string (YYYY-MM-DD).
For now you can use str_to_date to convert the string to date and compare:
select *
from tempLog
where str_to_date(date, '%d-%m-%Y') between '2017-03-23' and '2017-04-02';
However note that this will hinder the optimizer from using index on the column if any.
The correct remedy of the situation is fixing the table structure.
According to the documentation, you're supposed to use this format when writing a date: 'YYYY-MM-DD' (although it says it may accept 'YYYYMMDD' or even YYYYMMDD in some contexts).
When I am trying to convert varchar to date, I get Null values in return.
I have values as 05-MAR-2015 in my column.
I am running following query.
select STR_TO_DATE('n.Invoice_date','%d-%c-Y') from table n;
Once I run above query I get null values in return.
I want to introduce a new column in date format.
Note that the literal string 'n.invoice_date' is not a valid date. What you mean is:
SELECT STR_TO_DATE(n.invoice_date, '%d-%b-%Y') FROM TABLE n
Your error is in usage of %c instead of %b to get the date. You mixed the formatting of the date with the creation of a date value. This should do it:
SELECT DATE_FORMAT(STR_TO_DATE(n.invoice_date,'%d-%b-%Y'), '%d-%c-%Y') FROM table n;
This results in: 05-3-2015
Here you first create a date with STR_TO_DATE which must match the format in which it is stored in the field. Then you can format it with DATE_FORMAT in the way you want to.
See the MYSQL Docs for more information: http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html#function_date-format
How do you change date format from yy-mm-dd to day-month-year?
I have tried this:
UPDATE stock
SET date_in = DATE(STR_TO_DATE(date_in, '%d/%m/%Y))
WHERE DATE(STR_TO_DATE(date_in, '%d/%m/%Y') <> '00-00-0000';
But it is giving me an error.
You store dates in database in one of the date formats (date,datetime,timestamp)
When you want to format them for view, either use your language, which surly has a date formatting functionality, or use the intrinsic mysql date_format in a SELECT statment
I'm getting some strange results from using BETWEEN in my sql query. Wondering if anyone can help me to understand why i am getting these results.
I'm searching a date range in the format of dd/mm/yyyy. So i want to select all entries within a certain date range.
$dbSearchRecords_result = "SELECT * FROM $tbl_name WHERE Date BETWEEN '$DateFrom_order' AND '$DateTo_order'";
$dbSearchRecords_result = mysql_query($dbSearchRecords_result);
I am then calling the results in a while statement from an array
while ($row = mysql_fetch_array($dbSearchRecords_result)){
Now if I search BETWEEN 12/02/2011 14/02/2011 there is a date returned from 13/12/2010.
Yet if I search 12/02/2011 13/02/201 I do not get the result of 13/12/2010.
Any ideas would be most appreciated.
Thanks.
The BETWEENoperator is most likely reading your ranges as strings. From the book:
For best results when using BETWEEN
with date or time values, use CAST()
to explicitly convert the values to
the desired data type. Examples: If
you compare a DATETIME to two DATE
values, convert the DATE values to
DATETIME values. If you use a string
constant such as '2001-1-1' in a
comparison to a DATE, cast the string
to a DATE.
So, try:
SELECT * FROM `mytable`
WHERE `date` BETWEEN CAST('2011-01-02' AS DATE) AND CAST('2011-12-02' AS DATE)
MySQL's needs values in this format to do a proper comparison:
YYYY-MM-DD
you could use STR_TO_DATE to convert your string into the right format.
Plus obviously, the Date field needs to be of the DATE or DATETIME type.
try to format the values as DATE.. as in
$dbSearchRecords_result = "SELECT * FROM $tbl_name WHERE Date BETWEEN DATE('$DateFrom_order') AND DATE('$DateTo_order')";
