Java offsetdatetime returns '1970-01-01T00:00Z', which I am using in sql query to convert to IST timezone.
query :- select Date(cast('1970-01-01T00:00Z' as Timestamp),'Asia/Kolkata') as ist_date
error :- Invalid timestamp: '1970-01-01T00:00Z'
enter image description here
There is a need to parse the string first.
Select parse_timestamp("%Y-%d-%mT%H:%MZ","1970-01-01T00:00Z",'Asia/Kolkata')

I started with a date in a string format from a JSON extraction using this: json_value(answer, '$.date_created') and got an output 2020-01-02T10:26:47.056-04:00.
From there, I transformed the output (because I couldn't change it to date using a series of functions like regexp_replace, left and CAST) to a date-like string: 2020-01-02 10:26:47
I need to be able to transform this new string to a date. So far, I've tried with FORMAT_DATETIME and FORMAT_TIMESTAMP but I'm getting an error: Failed to parse input string bigquery
Your original timestamp string is just fine to do this:
select Date(timestamp("2020-01-02T10:26:47.056-04:00"))
Only thing here to check is: you have -4 offset from UTC so as long as you take care of timezone etc, above style should work fine.
I want to convert a string into timestamp
I am using the following command for it
SELECT To_timestamp ('12-31-2021-23-38-02', 'DD-MM-YYYY-HH24-MI-SS');
However it is returning me '2023-07-17 23:38:02' this instead of '2021-31-12 23:38:02'
Place of month & day in the input string doesn't match format string.
Use:
SELECT To_timestamp ('12-31-2021-23-38-02', 'MM-DD-YYYY-HH24-MI-SS');
As pointed out in the comments, it's apparent that you're using Postgres prior to version 10.
Since Postgres 10, your query throws below error:
ERROR: date/time field value out of range: "12-31-2021-23-38-02"

Bigquery cannot parse datetime from a date in spite of providing right format. Dates in my column are of the same format I used in the string:
SELECT EXTRACT(DATE FROM PARSE_TIMESTAMP('%Y-%m-%dT%H:%M:%S%z',"2021-03-22T14:00:00-03:00"))
This gives this error:
Failed to parse input string "2021-03-22T14:00:00-03:00"
I am trying to make this work by this answer
You should use %Ez instead of %z as in below
SELECT EXTRACT(DATE FROM PARSE_TIMESTAMP('%Y-%m-%dT%H:%M:%S%Ez',"2021-03-22T14:00:00-03:00"))
See Supported format elements for TIMESTAMP for more details
I'm trying to cast a string to timestamp but I'm getting the following error:
Failed to output to file. Query failed: Value cannot be cast to timestamp: 2020-03-23T05:17:44.000Z
I'm using the query below:
select CAST(purchase_date AS timestamp)
from main_table
You can use from_iso8601_timestamp function if timestamp with time zone type is acceptable.
Or, you can use date_parse function.
Try parse_datetime():
select parse_datetime('2020-03-23T05:17:44.000Z', '%Y-%m-%dT%H:%i:%s.%fZ')
Request your help as have been trying to solve this but not able to.
I have a column in athena which is string . I want to convert that column into timestamp in athena.
I have used the query:
select date_parse(timestamp,'%Y-%m-%dT%H:%i:%s.%fZ') from wqmparquetformat ;
But i am getting errors:
INVALID_FUNCTION_ARGUMENT: Invalid format: "1589832352" is malformed at "832352"
I have tried all the combination of Presto in timestamp format.
When i run the below query :
select to_iso8601(from_unixtime(1589832352));
I receive the below output:
2020-05-18T20:05:52.000Z
The date_parse() function expects (string, format) as parameters and returns timestamp. So you need to pass your string as shown below :
select date_parse(to_iso8601(from_unixtime(1589832352)),'%Y-%m-%dT%H:%i:%s.%fZ')
which gave me below output
2020-05-18 20:05:52.000
You need to pass the column name contains the value 1589832352 in your case
select date_parse(to_iso8601(from_unixtime(timestamp)),'%Y-%m-%dT%H:%i:%s.%fZ')
In your case you should cast timestamp as double for it to work as shown below:
select date_parse(to_iso8601(from_unixtime(cast(timestamp as double))),'%Y-%m-%dT%H:%i:%s.%fZ')
To test run below query which works fine.
select date_parse(to_iso8601(from_unixtime(cast('1589832352' as double))),'%Y-%m-%dT%H:%i:%s.%fZ')
For me, date_format works great in AWS Athena:
SELECT date_format(from_iso8601_timestamp(datetime), '%m-%d-%Y %H:%i') AS myDateTime FROM <table>;
OR
select date_format(from_iso8601_timestamp(timestamp),'%Y-%m-%dT%H:%i:%s.%fZ') from wqmparquetformat ;
