fix(sqllab): Floating numbers not sorting correctly in result column #17573

lyndsiWilliams · 2021-11-29T14:01:27Z

SUMMARY

Floating numbers were not sorting correctly in the result column. This was fixed by creating a parseFloatingNums function to parse any numbers in the result set.

TESTING INSTRUCTIONS

Go to SQL Lab
Enter the following query using the superset example database:

SELECT status, year, sum(sales)
FROM main.cleaned_sales_data
GROUP BY status, year

Click the sales column to sort
Observe that floating numbers are now sorting correctly

that's cool, didn't know that isNan was a function!

Oops, it's Number.isNan 😅

I think this will fail if the values are not numbers/NaN, can you check?

superset-frontend/src/components/FilterableTable/FilterableTable.tsx

+      const aValue = parseFloatingNums(a[sortBy]);
+      const bValue = parseFloatingNums(b[sortBy]);
+
+      String(aValue).localeCompare(String(bValue), undefined, {


if you're using localeCompare with the numeric option, then do you still need to convert to a float? It looks like you're converting to a float and then back again to a string? It seems redundant.

Also, nice find on localeCompare, but I don't think it's going to support multilingually unless you explicitly pass the language that you want to support as the second argument.

I need to parse the floating numbers for them to sort correctly, but localeCompare will only take strings. The numerical option allows it to check the strings for numbers.

@lyndsiWilliams but when you do String(aValue) and String(bValue) you're converting them back to strings. It should work if you just call localeCompare on the values without parseFloat, assuming you pass the numeric option:

"20.0".localeCompare("10", undefined, {numeric: true}) 1 "2.0".localeCompare("10", undefined, {numeric: true}) -1

I did a lot of playing around with this and figured out that the sorting works without localeCompare so I removed it and added testing in this commit. While testing I found any floating point number that had more than 2 floating points (like 12.001 or longer) is a string, while any other number is a number. I think originally, the floating numbers weren't sorting correctly because the types were mixed. Just using the parseFloatingNums function seems to solve this so maybe we can look at using localeCompare in the future for multilingual sorting, since it just seems to be causing issues in this instance. I also didn't realize you had to explicitly pass the language you want to support as a second argument, so I don't think I'll be able to make this work with localeCompare.

@lyndsiWilliams can you also write a test for this?

You got it! 😁

Nit:

Suggested change

return Number.isNaN(floatValue) ? value : parseFloat(value);

return Number.isNaN(floatValue) ? value : floatValue

Whoops, I missed that one! Thank you, fixed in this commit 😁
