I need to do masking of my data in order to hide it from the target audience.
Please find below existing table that I have right now. There are 3 columns in that table.
SNO FIRSTNAME LASTNAME
1 JAYVADAN DARJI
2 KAPIL CHAUDHARY
In the desired output, I want 4 columns with masking done as below. MASKED_NAME column would be an addition column the desired output.
The desired output that I want
SNO FIRSTNAME LASTNAME MASKED_NAME
1 JAYVADAN DARJI JXXXXXXN DXXXI
2 KAPIL CHAUDHARY KXXXL CXXXXXXXY
Thanks a lot in advance.

I have a table that looks like the following:
id | cars
1 | John's Honda
2 | Andrew's red lexus
3 | James has a bmw
I need to just get the last word of the "cars" column that shows the actual "car" name
I have tried the followings but I don't get the desired output
select substr(cars, -1)
from t
the code above just shows me the last charater of the column. Later, I tried the following:
select split(cars, ' ')[offset(1)]
from t
however, I got the "Array index 1 is out of bounds (overflow)" error. Can anyone help how this can be achieved with bigquery?
Consider below simple approach
select *,
array_reverse(split(cars, ' '))[offset(0)] as brand
from your_table
if applied to sample data in your question - output is
Note: there are really many ways to accomplish your case - so anoher one would be regexp_extract(cars, r'\b(\w+)$') as brand
Update: 1,2,3 are just examples it can also be 4,24,53
I have the following setup:
I store Data in BigQuery and use BigQuery as data source for my Data Studio project.
I have a column called Alarms and the data inside that column is as follow: it can be empty or 1 or 1,2 or 1,2,3 or 5,43,60 and so on. If it's empty or has 1 value then there is nothing to worry about, but if there are 2 or more values I have to do something.
name
Alarm
Mark
John
1
Eddie
1,2
Peter
1,2,3
What I need is to be able to put every value in a separate column or create a dropdown or something.
For example something like the table below or two drop down menus one to select the name and the other shows the alarms. (I prefer the drop downs).
name
Alarm
Mark
John
1
Eddie
1
2
Peter
1
2
3
Here I select Peter and the alarm drop down shows 3 alarms. or for Eddie it just shows 2 alarms and so on.
I read something about regex but I don't really understand how to put it to the test.
I found this online: (.+?)(?:,|$) but I don't know how to capture the output.
What I need is to be able to put every value in a separate column
Consider below approach
select * from (
select * except(alarm)
from your_table,
unnest(split(alarm)) flag with offset
)
pivot (min(flag) as alarm for offset in (0,1,2,3,4))
If applied to sample data in your question -output is
Here is what I am trying to do: Get all people with the same boss and email the boss. I can only use the table below and I would like to add another column showing the boss email which is found in the table.

Thanks for any help.
You use a join to do that. It looks like the code below. When joining to the same table you have to use an alias.
SELECT base.name, boss.email as boss_email
from the_table_name_you_did_not_say as base
join the_table_name_you_did_not_say as boss on base.boss = boss.name
Technically you don't have to use an alias on the base table if you select a wildcard * for some platforms
I'm trying to solve this query where i need to find the the top balance at each base. Balance is in one table and bases are in another table.
This is the existing query i have that returns all the results but i need to find a way to limit it to 1 top result per baseID.
SELECT o.names.name t.accounts.bidd.baseID, MAX(t.accounts.balance)
FROM order o, table(c.accounts) t
WHERE t.accounts.acctype = 'verified'
GROUP BY o.names.name, t.accounts.bidd.baseID;
accounts is a nested table.
this is the output
Name accounts.BIDD.baseID MAX(T.accounts.BALANCE)
--------------- ------------------------- ---------------------------
Jerard 010 1251.21
john 012 3122.2
susan 012 3022.2
fin 012 3022.2
dan 010 1751.21
What i want the result to display is calculate the highest balance for each baseID and only display one record for that baseID.
So the output would look only display john for baseID 012 because he has the highest.
Any pointers in the right direction would be fantastic.
I think the problem is cause of the "Name" column. since you have three names mapped to one base id(12), it is considering all three records as unique ones and grouping them individually and not together.
Try to ignore the "Name" column in select query and in the "Group-by" clause.
SELECT t.accounts.bidd.baseID, MAX(t.accounts.balance)
FROM order o, table(c.accounts) t
WHERE t.accounts.acctype = 'verified'
GROUP BY t.accounts.bidd.baseID;
I need a setup in Access where some rows in a table are converted to columns...for example, lets say I have this table:
Team Employee DaysWorked
Sales John 23
Sales Mark 3
Sales James 5
And then through the use of a query/form/something else, I would like the following display:
Team John Mark James
Sales 23 3 5
This conversion of rows to columns would have to be dynamic as a team could have any number of Employees and the Employees could change etc. Could anyone please guide me on the best way to achieve this?
You want to create a CrossTab query. Here's the SQL that you can use.
TRANSFORM SUM(YourTable.DaysWorked) AS DaysWorked
SELECT YourTable.Team
FROM YourTable
GROUP BY YourTable.Team
PIVOT YourTable.Employee
Of course the output is slightly different in that the columns are in alphabetical order.
Team James John Mark
Sales 5 23 3
