Hi I'm having a problem with looking up data on another table with AppSheet
Basically, when I scan in a barcode, I want the product name to lookup such that in SQL
SELECT productName
FROM productLookupTable
WHERE productLookupTable.barcode == the_scanned_barcode
However, I can't seem to do this in appsheet. I tried
LOOKUP([barcode],'productLookupTable','barcode','productName')
as the formula for the product name field in the add view and that didn't work either. Scanning a barcode didn't trigger a lookup, or it says match not found. (Two different scenarios of many combinations of things I tried.)
Any help would be appreciated.

I am trying to create a sheet to determine the amount of overlapping hours for employees.
I have one table with timeclock data for the Employees.
Table 1
And another with timeclock data for their Support Staff.
Table 2
This is the desired output. Each row from table A has all the date matches from table B. From here I would compute the number of overlapping hours in the final column and then roll that up into another sheet.
Table 3, Desired Output
(apologies for image links, I can't post inline images yet)
Sample sheet here Please let me know if you have any ideas for me!
I know its a combination of QUERY, ARRAYFORMULA, FILTER and more but I just can't find the right combo.
Here's a way of doing this type of join using only built-in functions:
=arrayformula(lambda(employee,support,
lambda(datecomp,
lambda(rows,
{vlookup(index(rows,,1),{row(employee),employee},sequence(1,columns(employee),2),false),
vlookup(index(rows,,2),{row(support),support},sequence(1,columns(support),2),false)})(
split(filter(datecomp,datecomp<>""),"|")))(
flatten(if(index(employee,,1)=transpose(index(support,,1)),row(employee)&"|"&transpose(row(support)),))))(
Employee!A1:D6,Support!A1:E5))
There's a lot going on here, but the basic idea is that we are comparing the date columns of each table against each other in a 2D IF array, and where the dates match we are obtaining the row index of each table. After some manipulations we can use these row indexes on each table in two side-by-side VLOOKUPs to obtain the joined table.
DMac,
I wrote myself a QUERY replacement custom function that uses real SQL select syntax.
For your data it looks something like (You need a tab called employee and a tab called support for this to work) :
=gsSQL("select * from employee full join support on employee.date = support.date")
See my test worksheet: (line 164 on gsSqlTest sheet)
https://docs.google.com/spreadsheets/d/1Zmyk7a7u0xvICrxen-c0CdpssrLTkHwYx6XL00Tb1ws/edit?usp=sharing
You need to add one Apps Script file to your sheet to give you the custom function:

For example, changing the column titles, it would be like:
select employee.name as name .... (rest of your select).
I have some personal data with first/last names, e-mails, institutions people work at, etc. There are many, many duplicates because this was collected from a few sources over 2-3 years. Sometimes the same person provided different versions of their name, a different e-mail address, etc. I'd like to have a compact version of this data, where a single person (identified by a PersonID) is listed on a single row, with unique variants of their name, e-mail, etc. listed in each cell. Bonus points if the values in every cell are sorted, but far from required.

I'm looking for a way to display the unique values in each column of a filter result, ideally staying away from =QUERY if at all possible.
This is easy to do when working with just one resulting column:
=FILTER(A4:A9,D4:D9=1) --> =JOIN(", ",UNIQUE(FILTER(A4:A9,D4:D9=1)))
...but the moment the filter spits out results in multiple columns:
=FILTER(A4:C9,D4:D9=1) --> ???
...I have no clue what to do, other than doing the code above for each column separately (which would be a hassle, given the number of columns involved). Is this possible?
Here's one way to do that using MAP:
=MAP(UNIQUE(D4:D),LAMBDA(id,BYCOL(FILTER(A4:D,D4:D=id),LAMBDA(col,JOIN(CHAR(10),UNIQUE(col))))))
By stablishing a column in I with unique values (=UNIQUE(D4:D)), you can use this MAKE ARRAY:
=MAKEARRAY(COUNTA(I4:I),COUNTA(F3:H3),LAMBDA(r,c,
JOIN(CHAR(10),FILTER(INDEX(A4:C,,c),D4:D=INDEX(I4:I,r)))))
I've read a few similar questions, and I can't seem to find exactly what I'm trying to do.
I have a roster of employees in sheet "Roster" with their names in Column A. In sheet "Hours" I have a list of assigned jobs for tomorrow, with the assigned employee's name also in Column A. I'm trying to add a column of employees from the roster that are NOT in the list of employees on jobs.
The closest I've gotten is with this, on the Hours sheet:
=ARRAYFORMULA(VLOOKUP('Roster'!A2:A, A2:A,1,0))
which gives me a list of the entire roster, with the missing ones returning an #N/A error that tells me the missing name when I mouse over it and read the error code. Is there a way to just get a list of the errors? Would I be better off attacking this from a completely different angle?
EDIT: Sanitized example pictures. If what I was trying to do worked, it would return Bob and Jim in this example.
Assuming you're trying to return this list in the "Hours" sheet, you can build off what you had. Try this:
=ARRAYFORMULA(FILTER(A2:A,ISERROR(VLOOKUP('Roster'!A2:A, A2:A,1,0))))
Keep in mind that this formula was written sight-unseen. If it doesn't work as expected, consider sharing a link to a copy of your sheet (or to a sample sheet set up the same way and with enough sanitized but realistic data to illustrate the problem, along with the manually entered result you want in the range where you want it).
I ended up going a completely different route. I made a third "Under the Hood" sheet, pulled the two columns into it with queries, ran a match formula down the list and returned "" on errors, then ran a query on Hours to get the names where it had null for the match list.
My sheet contains volunteer data imported via query from another worksheet. I'm assigning various roles to each volunteer on this sheet.
I'd like to alphabetize by last name to make it easier to locate names. But I need to be able to add names to the "Roster" while keeping the assignments with the correct names.
In my current setup, when I alphabetize, inserting a new name causes misalignment of assignments. Any ideas how I can avoid this?
Here's a test sheet to demo the process. The actual sheet contains dozens of volunteers and multiple data columns for each volunteer.

Thanks in advance
I am creating a tool for a video game I play.
Link to the example spreadsheet (Please make a copy to edit so that this copy stays intact for additional helpers).
Sheet 1 is “Choose Owned”. It contains a list of all of the champions available in the game and includes their attributes.
Column A contains checkboxes. Checking a checkbox indicates that the user owns that champion, and brings it to Sheet 2.
Sheet 2 is called “Owned”. It contains a list of the champions checked off in “Choose Owned” (aka the champions the user owns). “Owned” includes the champion attributes too, as first seen in “Choose Owned”.
Beyond those same attributes, “Owned” contains 8 additional columns.
These columns are from Columns G:N and are labeled ‘Level’, ‘Rank’,
‘Ascension Lvl’, and ‘Team Label(s)’ (‘Team Label(s)’ takes up
columns J:N). This data is all unique information and requires the
user to input the information themselves depending on their
champions.
Because there are so many champions, I want the user to be able to use the Filter function in “Owned” so they can easily locate the champion they need or sort the table however they wish.
However, because I use the QUERY function to get the data from “Choose Owned”, the Filter function tends to break. The most obvious error comes when you try to sort A-Z or Z-A; this simply cannot be done. I was fine with this, and have even included a note at the top telling the user to avoid sorting alphabetically.
Everything else works correctly until the user tries to add a new champion from “Choose Owned”. When the champion is added to “Owned”, the additional, unique data in columns G:N go out of order because they don’t move with their original champions.
Example:
I choose my champions. These champions are copied to “Owned”.
I pick their relative data in columns G:N.
A few days later, I obtain new champions and check them off in “Choose Owned” so they are added to “Owned”. However, when I do this, the champions stay in the same order as they are in “Choose Owned”, and columns G:N do not move with their champions so now, that information is with the wrong champion.
I want the additional data (G:N) to move with their champions when the table is edited due to champions being added. Or, in other words, I want those columns to stay linked to the first columns.
If there is a different way to achieve all of this like if I have to use a function other than QUERY, that is fine!
Please share any solutions you may have. I would prefer to not use a script but will consider the idea if it works.
this is a common issue within Google Sheets and it's solvable in 2 ways:
either by introducing a common value (unique ID) and then linking the manual input to query and aligning it by ID
or easier approach in your case - using timestamp/linear ID so every new entry would be added to the bottom and then the query would be sorted based on this order.
