QUESTION
I'm trying to get some insight in this room for optimization for a SQL query (BigQuery). I have this segment of a WHERE clause that needs to include all instances where h.isEntrance is TRUE or where h.hitNumber = 1. I've tested it back and forth with CASE statements, and with OR statements for them, and the results aren't wholly conclusive.
It seems like the CASE is faster for shorter data pulls, and the OR is faster for longer data pulls, but that doesn't make sense to me. Is there a difference between these or is it likely something else driving this difference? Is one faster/is there another better option for incorporating this logical requirement into my query? Below the statement is my full query for context in case that's helpful.
Also open to any other optimizations I may have overlooked within this query as lowering the runtime for this query is paramount to its usefulness.
Thanks!

Answered 2021-Jun-07 at 15:35I found a solution to my problem. In fact, just as I suspected, there was a missing directory to my PYTHONPATH. It was the directory that contained the gtts package.
Solution: If you have the same problem,
- Find the package
I looked at that post
- Add it to sys.path (which will also add it to PYTHONPATH)
Add this code at the top of your script (in my case, the pipelines.py):
QUESTION
I want to fix this below issue in csv file using unix. I don't have access to source so i have to fix with this csv file alone. I need to desired output. is it achievable. Please help.
I have tried this below code but it doesn't work.
...ANSWER
Answered 2021-Jun-02 at 04:41You can fix the output fairly simply with awk using 3-rules. Specifically, you will check that each line begins with a date in your format and ends (e.g. the 4th field $4) with 4-digits. If so, just print the line (rule 1). If not, and the line begins with a date in your format, just output without a '\n' so you can append the next line to it (rule 2). If you have reach a line that satisfies neither rule 1 or rule 2, it is the end of the previous line, just output with a '\n' to complete the previous line (rule 3).
That can be done with:
