My MySQL's timezone is UTC. I have many columns with type timestamp. All values in it are stored in UTC. I want to retrieve only one column's date in IST format. I do not want to modify the current dates in the column. Is there any way by which I can change the timezone while retrieving from this particular column?
I want to avoid doing CONVERT_TZ() every time when I am fetching the column. Instead, I am looking for something that will apply this function to a column by default so I do not need to do it every time.
You need to change the query to :
$mysqli->query("set time_zone = '+05:30'");

I have a date time field and want to split the date and time as separate parameter's. I've been able to set the date parameter but not the time, does any one know how this can be done or to include time in the datetime parameter too?
Is it possible to get the datetime when only there are any data changes in the table/matrix?
I don't want to always get the current datetime. I want the datetime to be refreshed only when there is a change to the data in the table/matrix.
This is only possible of you are storing a timestamp in the rows of data that are being queried. If you are storing that timestamp, then simply query it and render it outside of the tablix - you could use a Max() aggregate function to find it from the rows of data.
The table doesn't have any date time column. I want to if there is any inbuilt keyword which can does that.
I want to know all commits done after a particular date.
If flashback is enabled on the database you can get records on the table in an around a particular date range in Oracle.(It purely depends on if its enabled and for how long the flashback needs to be kept)
You can query to see the data in the table as of 3 days back as follows
select *
from table as of timestamp sysdate-3
In my mysql database table i have two columns called "date" and "time". "date" datatype is set to DATETIME and "time" datatype is set to TIMESTAMP. what i want to do is store only date in "date" column and store only time in "time" column. my table name is "loans".I'm not good in SQL querying. someone please show me exactly how to do that.
And also i have some another problems with time zones. i want to convert my database time format to UTC -5:00 (us time).how can i do that without change my PC time ?
Separating DATE and TIME for same event is a bad idea. I would go for storing it in simple DATETIME field.
But you can do it with this
Give date field type DATE(not DATETIME) and time field type TIME (yes it exists and not TIMESTAMP)
Now this will allow you to store date in YYYY-MM-DD and time in HH:MM:SS
To set the time zone of your MYSQL server you can use this one

The problem comes when i try to retrive dates from the data and have them in ascending or descending order since mysql treats them as strings instead of dates the output isnt quite correct.
Is there anyway i could retrieve the dates telling mysql to treat them as dates and not strings?
thats probably because it is not a datetime datatype in the database.. its a string.. use the STR_TO_DATE() function to convert it to a date.
