I have a query that returns a date with type timestamp_ltz, but i want to convert it to the pacific time zone
select
INVOICE."ID" "ID",
INVOICE.CUSTOMER_ID CUSTOMER_ID,
INVOICE."DATE":: timestamp_ltz,
How can i make this conversion in snowflakes?
I tried to select using
convert_timezone('UTC','America/Los_Angeles', INVOICE."DATE")::timestamp_ltz
but it's returning an error

I have timestamps like the following '2018-04-18T18:11:16+01:00' in varchar type and want to transform them to a timestamp type. I am having trouble using the to_timestamp(). Is there a specific way to use the to_timestamp() function that will allow me to do the transformation i want? If not, is there any other way to achieve my goal?
Doing
to_timestamp('2018-04-18T18:11:16+01:00', 'DD-MM-YYYY HH24:MI:SS')
gives an error of
Error: date/time field value out of range:
"2018-04-18T18:11:16+01:00"
I would expect varchars like '2018-04-18T18:11:16+01:00' to be transformed to 2018-04-18 17:11:16 (where type is timestamp)

If you simply want to get the string into a timestamp holding the time zone:
Simply cast it into timestamp with time zone (= timestamptz) type:
SELECT '2018-04-18T18:11:16+01:00'::timestamptz
If you just want to cut the time zone part and holding the time without any further calculations: Simply cast it into type timestamp without time zone (= timestamp)
SELECT '2018-04-18T18:11:16+01:00'::timestamp
If you want to convert it into a timestamp at UTC (calculating -1) you can do:
SELECT ('2018-04-18T18:11:16+01:00' AT TIME ZONE 'UTC')::timestamp
Need to get the date part from column Start_DateTime (varchar data type) which is having data like '06/04/19 10:44 AM CDT' , '06/10/19 11:56 AM EDT' and need to convert the time zone to CST time zone
I have a user defined function dbo.fn_UTCtoCST that will convert the time zone but am trying to combine all this in a select query to get the desired result
SELECT
Start_DateTime
,Inspector
,Status
,Distance
,Location
from XYZ
If your function is scalar value function(returning one value) then this might will work for you.
select *
from A
cross apply dbo.fn_UTCtoCST(date) cstdate.
ERROR: timestamp units "timezone" not supported
That's the error I get for all timezone fields.
Here's a minimal query you can run:
select extract(timezone_hour from now()::timestamptz at time zone 'US/Eastern');
What I want is the utc offset in hours. So this should return -4.
The requirement is that I use a dynamic time zone in the query. So I have a table of "facilities" with time zone strings, and I need to get the current time for each one.
So my end query should look something like this:
SELECT
EXTRACT(timezone_hour from now() with time zone timezone) # timezone is the name of the field
FROM facilities;
I thought I had it for a second with this, but this is giving me my current offset, not the offset of the tz I'm passing:
select
extract(timezone_hour from (select now()::timestamp at time zone 'US/Eastern'))
date_part
-----------
-7
I ended up getting this to work with creating two timestamps, one at utc and one at the desired time zone, but I'll leave this open just in case there's a better solution than my current one:
select
extract(hour from (
select (
select now() at time zone 'US/Eastern') - (select now() at time zone 'UTC')));
date_part
-----------
-4
I have a column called login_timestamp, which is of type TIMESTAMP WITH TIME ZONE.
To retrieve the month for this timestamp, I would do: EXTRACT(MONTH FROM login_timestamp).
However, I would like to retrieve the month for a specific time zone (in my case, Pakistan), but can't figure out how to do that.
Documentation for this is under Date/Time Functions and Operators. Search that page for "at time zone".
select extract(month from login_timestamp at time zone 'Asia/Karachi');
You can change the time zone for a single session or for a single transaction with set session... or set local.... For example, this changes the time zone for the current session.
set session time zone 'Asia/Karachi';
Use the AT TIME ZONE construct:
SELECT EXTRACT(MONTH FROM login_timestamp AT TIME ZONE '-5');
-5 is the constant offset for Pakistan.
Details:
Ignoring timezones altogether in Rails and PostgreSQL
Try applying AT TIME ZONE. Demo
select extract(month from cast ('2017-07-01 01:00+03' as TIMESTAMP WITH TIME ZONE) AT TIME ZONE '+08') as monthNo
returns
monthno

I have a column in my table which is of type Timestamp.
while converting this field to the format: 2003-08-09T05:48:37+05:30, I am using the following query:
select
TO_CHAR(CONSUMER_DLY_TIME, 'YYYY-MM-DD"T"HH24:MI:SSTZH:TZM')
from oms_cust_ord_head;
it gives me the error: "date format not recognized"
How to resolve this ?
A TIMESTAMP value does not contain any time zone information, thus you cannot display it.
Which time zone do you want do be shown?
For time zone of database operating system you can use:
SELECT
TO_CHAR(CONSUMER_DLY_TIME, 'YYYY-MM-DD"T"HH24:MI:SS')||TO_CHAR(SYSTIMESTAMP, 'TZH:TZM')
or for you current session time zone:
SELECT
TO_CHAR(CONSUMER_DLY_TIME, 'YYYY-MM-DD"T"HH24:MI:SS')||TO_CHAR(CURRENT_TIMESTAMP, 'TZH:TZM')
SELECT
TO_CHAR(CAST(CONSUMER_DLY_TIME AS TIMESTAMP WITH TIME ZONE), 'YYYY-MM-DD"T"HH24:MI:SSTZH:TZM')
SELECT
TO_CHAR(CONSUMER_DLY_TIME, 'YYYY-MM-DD"T"HH24:MI:SS')||TZ_OFFSET(SESSIONTIMEZONE)
You should use
select trunc(<timestamp_column>) from your_table
Read Format Models in detail.
Note: Format in which the date will be displayed depends on your session parameter nls_date_format.
