I'm trying to generate a query that will display the date difference between a date stored in a column and the current date, but i'm getting the error:
"Cannot call method "getTime" of null."
What function can I use to calculate this date difference in Google Cloud SQL?
Current code:
SELECT date, DATEDIFF(date, CURRENT_DATE()) AS daysLeft
FROM table;
Are you using a mysql instance on Google Cloud. If so try the following
SELECT date, DATEDIFF(date, CURDATE()) AS daysLeft
FROM table;
All that changed is CURDATE() instead of CURRENT_DATE()
Turns out, the error was in another part of the code. The originally posted SQL query works perfectly fine, the problem was the model was casting the result as a date variable instead of an int.
The DATEDIFF function requires three parameters.
SELECT date, DATEDIFF(day, date, CURRENT_DATE()) AS daysLeft
FROM table;
This should return your result in days left.

I'm trying to write a query to return records from a column called "businessdate" (which is in the YYYY-MM-DD format, and it is a string data type), using the previous days "businessdate" records and am stuck. I've tried different things, and I get error messages ranging from argument or matching method, etc. It's probably simple, and I feel dumb. Please help!
Query;
Select businessdate from dbname
Where businessdate = current_date - 1
Use date_sub function to subtract one day from current_date:
select businessdate
from dbname.tablename
where businessdate = date_sub(current_date,1)
i'm stuck with this part of the query, where I need to get only just month and year from my table.
To put in context, i have tried with "TRUNC_DATE", and Oracle give me back an error like
ORA-00904: "DATE_TRUNC": invalid identifier sql
This piece of query get it from Udacity, but in sql Developer looks like it doesn't work.
When I try search deeper, I find something like convert(char(7), ia.invoice_date(), 120) yearMonth, It still not working and an error came back. ORA-00936: missing expression
I tried a lot of ways but no solutions.
If anyones have an idea o something that could help, I will be grateful.
Here below I paste the fragment of the query for guide help:
SELECT
COUNT(ia.invoice_id) total_de_facturas,
SUM(ia.invoice_amount) monto_total,
convert(char(7), ia.invoice_date(), 120) yearMonth
FROM AP.ap_invoices_all ia
GROUP BY ia.vendor_id;
You ae mixing Oracle syntax with Postgres (date_trunc()) and SQL Server (convert()). Many date functions are vendor-specific, so you learn the relevant syntax for your database.
In Oracle, you would use trunc() to truncate a date to the first day of the month:
trunc(ia.invoice_date, 'mm')
Use the EXTRACT function, try these out to test how it works and use it in your query -
SELECT EXTRACT(YEAR FROM DATE '2020-03-07') FROM DUAL;
SELECT EXTRACT(MONTH FROM DATE '2020-03-07') FROM DUAL;
If you want a string value in YYYY-MM format - which seems to be your intention from the 120 style and the char(7) in the SQL Server-syntax convert() call - then you can just use to_char() with that format model:
to_char(ia.invoice_date, 'YYYY-MM') as yearMonth
You don't need to truncate to the first of the month as you're discarding the day part anyway.
I have the table ORDERS and while trying to find the processing time for each order by subtracting the date of receipt from the date of delivery, I keep getting this error:
SQL0206N "DAY" is not valid in the context where it is used.
SQLSTATE=42703
My query is the following:
SELECT DATEDIFF(DAY, ReceiptDate, DeliveryDate) FROM ORDERS
I suspect it has something to do with the date's format in the columns ReceiptDate and DeliveryDate: DD/MM/YY. Does this have to be converted? What am I doing wrong?
EDIT: Is there an alternative for using DATEDIFF? Can I convert each individual date to an int of days and then subtract the two ints?
If you are using DB2, then there is no DATEDIFF function, which is specific to SQL Server. However, we can easily simulate it by taking a difference of days, using the DAYS() function:
SELECT DAYS(DeliveryDate) - DAYS(ReceiptDate) AS days_diff
FROM ORDERS;
my table has a date column. its data type is date. I confirmed it by going to table name>>columns and it says MTH_END_DT [DATE, Not NULL]
I want to filter my data for a particular date. If I put a condition where MTH_END_DT = '6/1/2018' I get an error select failed [3535] A character string failed conversion to a numeric value.
I followed this page. I used where MTH_END_DT = date '6/1/2018' and i get an error syntax error invalid date literal
I tried where cast(timestamp_column as date) = date '2013-10-22'; something like this and it throws error too
How should i filter my data?
There's only one reliable way to write a date, using a date literal, date 'yyyy-mm-dd'
where MTH_END_DT = DATE '2018-06-01'
For a Timestamp it's
TIMESTAMP '2018-06-01 15:34:56'
and for Time
TIME '15:34:56'
In SQL Assistant it's recommended to switch to Standard SQL format YYYY-MM-DD in Tools-Options-Data Format-Display dates in this format
I did have the similar problem when I was filtering a particular date for my query with Teradata. First method I tried was putting 'DATE' term as the following:
WHERE saledate = DATE'04/08/01' but this did not solve the problem.
I then used an approach I stumbled upon when surfing, finally it worked.
WHERE extract(year from saledate)=2004 AND extract(MONTH from saledate)=8 AND extract(DAY from saledate)= 1 source
I think this really should not be this long, but it worked.
It seems to me it’s most likely you have input the date format incorrectly? Maybe it includes a time by default.
For example
where MTH_END_DT = ‘2013-10-22-00:00:00:00’
I'm trying to create a custom query in Tableau to use on Google's BigQuery. The goal is to have an offset parameter in Tableau that changes the offsets used in a date based WHERE clause.
In Tableau it would look like this:
SELECT
DATE_ADD(UTC_USEC_TO_MONTH(CURRENT_DATE()),<Parameters.Offset>-1,"MONTH") as month_index,
COUNT(DISTINCT user_id, 1000000) as distinct_count
FROM
[Orders]
WHERE
order_date >= DATE_ADD(UTC_USEC_TO_MONTH(CURRENT_DATE()),<Parameters.Offset>-12,"MONTH")
AND
order_date < DATE_ADD(UTC_USEC_TO_MONTH(CURRENT_DATE()),<Parameters.Offset>-1,"MONTH")
However, BigQuery always returns an error:
Error: DATE_ADD 2nd argument must have INT32 type.
When I try the same query in the BigQuery editor using simple arithmetic it fails with the same error.
SELECT
DATE_ADD(UTC_USEC_TO_MONTH(CURRENT_DATE()),5-3,"MONTH") as month_index,
FROM [Orders]
Any workaround for this? My only option so far is to make multiple offsets in Tableau, it seems.
Thanks for the help!
I acknowledge that this is a hole in functionality of DATE_ADD. It can be fixed, but it will take some time until fix is rolled into production.
Here is a possible workaround. It seems to work if the first argument to DATE_ADD is a string. Then you can truncate the result to a month boundary and convert it from a timestamp to a string.
SELECT
FORMAT_UTC_USEC(UTC_USEC_TO_MONTH(DATE_ADD(CURRENT_DATE(),5-3,"MONTH"))) as month_index;
