To use it with a string
Quite often if you open a CSV file in Excel with American date formats Excel will do its best to convert them (badly) and you end up with some in date format and some in text format.
This formula helps to sort it out.
So 6/21/16 becomes 21/06/2016 and 5/29/16 becomes 29/05/2016
Find the Monday for a week that a date falls into
Where A2 is the field with the date.
The great thing is that
- It works across year breaks and you don’t end up with Week 53
- It fits with SQL – date_trunc(‘week’, Date) – functions so you can correctly match Excel data
This is something I do regularly, wanting to look at log activity over a 30 minute range
Use datediff and “mins” datepart like this
(datediff(mins,’2016-05-04 15:50′,DATE) between 0 AND 30)
This looks at a 30 minute window around 16:00 hrs
This should be easy
url_domain || url_path || url_query_params as request
really should work.
BUT if any one of these is null it will deliver a null string
So you need
nvl(url_domain,”) || nvl(url_path,”) || nvl(url_query_params,”) as request
This replaces a Null with a blank.
Why can’t it do this anyway? Who knows.
This is quite straight forward but seems to cause confusion on the internet
Time to the nearest 10 minutes
TO_CHAR(DATE,’HH’) || ‘:’ || trim(TO_CHAR((ROUND((DATEPART (MINUTE,DATE) / 10),1)*10),’09’)) AS mins10
so you get
12:00 – 12:00
12:01 – 12:00
12:03 – 12:00
12:11 – 12:10
This imports into excel as a time
Time to the nearest 5 minutes
Just change the multiplier
TO_CHAR(DATE,’HH’) || ‘:’ || trim(TO_CHAR((ROUND((DATEPART (MINUTE,DATE) / 5),1)*5),’09’)) AS mins5
Time to the nearest minute
Time to the nearest hour
Day of the week
This puts you to the nearest Monday in that week which is more useful than the week number
It is quite easy and very useful if you are running complex and long calculations.
- Add Excel to you Start Menu. – In the program files right click Excel and chose “Add to Start Menu”
- Shift Click Excel on Start Menu – this opens a new version separate from any previous one.
- Add Excel to you Taskbar. – In the program files right click Excel and chose “Add to taskbar”
- Shift Click Excel on the Taskbar – this opens a new version separate from any previous one.
As far as I can tell you can only run two versions at a time.

This method is almost instant (using 500,000 record lookups)
IF(M56=INDEX(‘Sitemap Keyword Categories’!$G$1:$G$300016,MATCH(M56,’Sitemap Keyword Categories’!$G$1:$G$300016,1),1),”Supported”,”Not Supported”)
This does an “nearest match” (using status “1”) and then tests to see if the nearest match is correct (ie “M56=”).
This Updated 500,000 records in under 1 second – previous methods (exact match using “0” and vlookup function ) would take 5 minutes.
It is vital that the column G in “Sitemap Keyword Categories” is sorted A-Z
