EntryDate which is datetime datatype

LastEdited with datetime datatype.
You need to run a query to sort date..like
SELECT TaskDate FROM MyTask Order By TaskDate limit 1
SELECT TaskDate FROM MyTask Order By TaskDate Desc limit 1
First one will give u oldest date and second will give the latest date.
hope this will help u out.

The code is written in postgresql and run in pgadmin 4.
I am trying to get the id from the pricing table if the current date lies in between the given start date and end date.
I am trying to get the id from the pricing table if the current date lies in between the given start date and end date.
select id
from pricing
where current_Date between start_date>=date '2022-10-19' AND end_date<=date '2022-10-20';
The error raises
operator does not exist: date >= boolean LINE 3: where
current_Date between start_date>=date '2022-10-19'...
Your where condition is essentially someDate between someBoolean and someOtherBoolean, which confuses compiler. Use just this:
where current_Date between date '2022-10-19' AND date '2022-10-20'
between only expects the values:
select id
from pricing
where current_Date between '2022-10-19' AND '2022-10-20';
Every month I download a set of data into a report. That data consists of multiple records and each record has a record specific date as well as having the month end report date on the record's data-row.
I have used Power Query to upload all of these month end reports. I want use Power Query to be able to compare the column of record dates with the earliest date in the column of report dates to see if anybody has fiddled any data entry. The query table has the following headings.
Record ID Record Date Report Date
I've tried adding a custom column using the formula = if Record Date < List.Min(Report Date) then "Old" else "New"
this didn't work and I've spent ages trying to get a solution. I've also tried using Groups to get the minimum value, but I lose all of the other columns, which I want to keep. Any help really appreciated.
You have to refer to the fields in [], so here [Report Date]
To pick a column use Source[Field], so here #"PriorStep"[Report Date]
The List.Min function is not pulling as a number so you cant use <
Insert a Number.From in front of the calculation to convert to number
Same need to add Number.From in front of [Record Date] pulling as a date
Combined code:
#"Added Custom" = Table.AddColumn(#"PriorStep", "Custom", each if Number.From([Record Date])<Number.From(List.Min(#"PriorStep"[Report Date])) then "Old" else "New")
I already have a date time column which is updated every time I ingest new data and it works, but I would like to do the same for a new column but just with the date, not the time. Please see the picture attached. What should I write in the Default option? Table column definitions
You could set the default value to CURRENT_DATE ON UPDATE CURRENT_DATE in your EventDate field.
But wouldn't it be better to extract date from the already existing EventDateTime field with DATE_FORMAT(EventDateTime, '%Y-%m-%d') or DATE(EventDateTime) functions?
This might be a simple one but I haven't got a solution yet. I have a create_date field which is a date type, and a revenue number. I want to see weekly break down of revenue.
I can get the numbers easily in tableau because of built in functionality but doing it in PostgreSQL is where I need some help.
If you want the revenue by week, you'll need to group and aggregate:
select extract (week from create_date) as week, sum(revenue) from table group by week
Table X has start_date and end_date and related information associated with these dates. BOTH stored in DB in date format.
I need to find a specific date say 12th-Jan-2000 and extract the rows whose date range includes this date.
Could someone please help me out. I am new to SQL so need some guidance here.
Table X:
ID |start_date|end_date
1 |12/30/1999|01/12/2000
2 |01/20/2000|01/30/2000
3 |01/07/2000|01/15/2000
Thus my query should give back the ID-3 since 12th January falls in the range 01/07/2000-01/15/2000
Thanks
use the BETWEEN operator:
SELECT *
FROM TableX
WHERE DATE'2000-01-12' BETWEEN start_date AND end_date
