We can use across in group_by to include all of vars columns along with YEAR.

I think you need a very clear definition of overlap. If you have [2;7], [6;10] and [7;8], which one overlaps with which one ?

Avoid using input as a variable name, it shadows the function input() (to get input from the user)

If you want to select clear overlaps (only the start or the end differs), and you only have at most ONE overlap, here you go:

The difference between to top 5 strings and the bottom 5 is that the top ones end with _code and the bottom ones end with _app_code, everything else, in this case, remain the same.

To match all the top 5 strings then you might want to use a negative lookbehind

QUESTION

BigQuery regex lookbehind / lookahead workaround?

Asked 2021-Apr-22 at 03:48

Doing ETL with BigQuery, I aim at cleaning up some text codes:

The standard syntax of these codes is ABC D123 or ABCD D123 (a group of letters, followed by a space, followed by another letter, followed by a group of numbers).

Some numbers however have a O (capital letter) entered instead of a number 0 (zero). These errors are found at the end of the number sequence: so ABC D56O should become ABC D560.

I tried using regexp_replace() using a lookbehind assertion such as (?<=[0-9])O.

However, it seems the r2 library isn't handling lookbehind, see this post from 2013 for reference.

So is there a workaround for this?

ANSWER

Answered 2021-Apr-22 at 03:48

These errors are found at the end of the number sequence

Why not just simply replace O (capital letter) to 0 (zero) when it is at the end of the code - as it is in below example

ANSWER

RE2 based solution

As RE2 does not support lookarounds, there is no pure single-pass regex solution.

You can have a workaround (as usual, when no solution is available): replace the string twice with (\d),(\d) regex and $1$2 substitution:

This is indeed due to the lack of RAM on the free tier VM. Binary packages would indeed solve this. But will see whether we can do something about that as well.

Vulnerabilities

No vulnerabilities reported

Install re2

You will need [re2][] installed as well as a C++ compiler such as [gcc][] (on Debian and Ubuntu, this is provided by the [build-essential][] package). If you are using Mac OS X, I recommend installing re2 with [Homebrew][] by running the following:.
/usr/local
/opt/homebrew
/usr

Support

Full documentation automatically generated from the latest version is available at http://mudge.name/re2/. Note that re2’s regular expression syntax differs from PCRE and Ruby’s built-in [Regexp][Regexp] library, see the [official syntax page][] for more details.
