I uploaded a google sheet into BQ and the date format is "DOW mm/dd/yyyy" and of course BQ recognizes it as a string. I want to convert it to date without the DOW. How can I do this without changing the date format in google sheets (which is not an option)?
use below
select parse_date('%a %m/%d/%y', 'Fri 12/25/20')
with output
You just need to use the CAST as DATE function with the appropriate format string

I am kinda new in BigQuery, recently I was working on a project. I want to convert above type of format into yyyy/mm/dd format. How will I do that?
You can combine PARSE_DATE with FORMAT_DATE to get the desired output:
SELECT FORMAT_DATE("%Y/%m/%d",PARSE_DATE("%B %d, %Y","June 10, 2014")) AS date_str
PARSE_DATE will parse the provided string into a DATE type value in BQ format (YYYY-MM-DD) and then FORMAT_DATE will format this DATE to a string with the desired output.
In case someone is wondering how to convert the whole column;
FORMAT_DATE("%Y/%m/%d",PARSE_DATE("%B %d, %Y",ColumnName)) as DesiredColumnName
I have a list of strings such as 6/20/2019 that I need to convert to date format in BigQuery. Have issues with the leading 0's and this text being recognized as an actual date/time format when being used in BigQuery SQL or being pulled into Tableau as such.
Doesn't parse_date() work?
select parse_date('%m/%d/%Y', '6/20/2019')
I am trying to convert the String "181201" into a Date field in Google Big Query using standard SQL.
Ex. 181201 -> 2018-12-01
I have tried to use the following which worked because the original date I inputted had the entire year spelt out as "2018". However, I do not have the entire year written out in my data set.
SELECT PARSE_DATE('%YY%m%d', '20181201') AS DATE
How can I update my query to use only yymmdd to give me yyyy-mm-dd?
THANK YOU!
SELECT SAFE.PARSE_DATE('%y%m%d', '181201')
I am streaming inserts into bigquery from adwords javascript. The javascript time stamp that gets inserted into the bigquery table as a string - "Sun Sep 06 2015 02:42:54 GMT-0700 (PDT)". How do i convert this string into a timestamp of format "2015-09-06 02:42:54" in a bigquery select statement.
You can do this by parsing out each part of the date (year, month, day, etc.) using the REGEXP_EXTRACT function, then constructing a string to pass into the TIMESTAMP function. You can check out the query reference for more info on these functions. See also: a similar question with a different initial date format.
Note however that BigQuery TIMESTAMPs are stored as UTC times, so you may want to shift the time according to the timezone in the string.
I have two columns. ColA and ColB contains char(10) with data "20090520" and "20090521".
I want to select and get the date difference in days. I have tried using Format() and CDate()
but MS Access always display as #ERROR.
Access prefers its dates in this format:
#2009-12-01#
You can convert your date to something Access understands with:
CDate(Format([ColA], "0000-00-00"))
Or alternatively:
DateSerial(Left([ColA],4),Mid([ColA],5,2),Right([ColA],2))
And to display the result in your preferred format:
Format(<date here>, "dd-mm-yyyy")
Try using DateSerial() to convert the dates:
DateSerial(Left([FieldName],4),Mid([FieldName],5,2),Right([FieldName],2))
If at all possible, change the datatype to a date datatype. You should not store dates as character data.
I am connecting to another database which I have no control on. That is why this problem occurred. Thanks for the feedback.
