## How to export a MYSQL RDS database table that includes two text fields to a CSV file

I have a MYSQL database in RDS. I am trying to export the data from a table but cannot get it to format correctly due to two of the fields being text fields.

The command I am trying (an what seems like a million small variations of at this point)

`````` mysql -h <server here> -u <database user here> -D <database name here> -p -e "SELECT id, first_name, last_name, description, email, department, title, created_at, updated_at FROM bios WHERE status = 1" > prod_bios.csv
``````

This file comes out a total mess. I have tried to use things like this after reading through the documentation

`````` ... WHERE status = 1 FIELDS ENCLOSED BY '"' TERMINATED BY ';' ESCAPED BY '"'  LINES TERMINATED BY 'rn' " > ...
``````

I also tried to use the `QUOTE()` method. None of that made any difference.

Can anyone help me get the syntax correct to export this table with the description set inside quotes so I can escape it and have a CSV file that is formatted correctly?

Thanks so much for any help!

## postgresql – postgres includes the column listed in the sort key and therefore fails to use the index

This is a query that occurs quite frequently:

``````SELECT DISTINCT id, published_year, first_author FROM publication ORDER BY published_year DESC NULLS LAST LIMIT 10;
``````

There is an index that could be used for this:

``````CREATE INDEX publication_published_year_idcombineddesc2_btree ON public.publication USING btree (published_year DESC NULLS LAST, id)
``````

However, it is not used and the request therefore lasts 30 to 40 seconds:

``````EXPLAIN ANALYZE SELECT DISTINCT id, published_year, first_author FROM publication ORDER BY published_year DESC NULLS LAST LIMIT 10;
QUERY PLAN
----------------------------------------------------------------------------------------------------------------------------------------------
Limit  (cost=3527756.39..3527756.49 rows=10 width=23) (actual time=33860.282..33860.292 rows=10 loops=1)
->  Unique  (cost=3527756.39..3623290.85 rows=9553446 width=23) (actual time=33860.280..33860.288 rows=10 loops=1)
->  Sort  (cost=3527756.39..3551640.01 rows=9553446 width=23) (actual time=33860.278..33860.281 rows=10 loops=1)
Sort Key: published_year DESC NULLS LAST, id, first_author
Sort Method: external merge  Disk: 310440kB

Planning time: 1.157 ms
Execution time: 33945.457 ms
``````

Now if I delete the first_author or DISTINCT, the request runs well and quickly:

``````EXPLAIN ANALYZE SELECT DISTINCT id, published_year FROM publication ORDER BY published_year DESC NULLS LAST LIMIT 80;
QUERY PLAN
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Limit  (cost=0.43..4.57 rows=80 width=10) (actual time=0.055..0.250 rows=80 loops=1)
->  Unique  (cost=0.43..493764.18 rows=9553446 width=10) (actual time=0.053..0.236 rows=80 loops=1)
->  Index Only Scan using publication_published_year_idcombineddesc2_btree on publication  (cost=0.43..445996.95 rows=9553446 width=10) (actual time=0.051..0.204 rows=80 loops=1)
Heap Fetches: 1
Planning time: 1.487 ms
Execution time: 0.300 ms

EXPLAIN ANALYZE SELECT id, published_year, first_author FROM publication ORDER BY published_year DESC NULLS LAST LIMIT 10;
QUERY PLAN
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Limit  (cost=0.43..9.63 rows=10 width=23) (actual time=0.062..0.190 rows=10 loops=1)
->  Index Scan using publication_published_year_idcombineddesc2_btree on publication  (cost=0.43..8787896.00 rows=9553446 width=23) (actual time=0.061..0.186 rows=10 loops=1)
Planning time: 1.380 ms
Execution time: 0.223 ms
``````

So my question is this: is there a way to force the query planner to use an index in the first case?

## Unity: prefab export includes many dependencies on unnecessary resources

I come `exported` one of my assets in a `unitypackage`.
He understood all the dependencies very well so that I could use them.

Then I tried another `prefab` but he understood a lot of `unrelated assets` from everywhere in the project, it's a very simple prefab and I don't know how the bulk is considered `dependencies`.

When I do `show dependencies` it brings up the clutter in the project menu. In no case should there be dependence. It really is not as complex as a prefab.

I also checked the prefabricated elements to see if some of them somehow use the clutter said, they are not.

How can this happen? Is there a way to fix it (other than a selective click in the export menu)?

## mysql – How to filter table 2 before joining table 1 so that the result always includes all table 1, even if there is no match in table 2?

The following returns all the rows of table 1 where post_type = dlm_download. It groups the values ​​in table 2 by the corresponding column in table 1 so that each row in table 1 has at most one corresponding "result" in table 2. The result is that all the records in table 1 are displayed in all cases, just display null for download_date when nothing in table 2 matches (which means that no one has downloaded the file yet):

``````SELECT p.post_title AS 'Download title', p.ID AS 'Download ID', MAX(l.download_date) AS 'Last download'
FROM wp_posts p
AND p.post_status = 'publish'
GROUP BY p.ID
``````

I also want to filter the records in table 2 that match some conditions … before being matched with table 1. But the following additions to the query, placed between WHERE and GROUP BY, ultimately reduce the result of 70 lines to 59, eliminating the lines of table 1 even if nothing in table 2 matches (previously displayed as NULL for the date of download)

``````AND l.user_agent NOT LIKE '%bot%'
AND l.user_agent NOT LIKE '%crawl%'
AND l.user_agent NOT LIKE '%panscient%'
AND l.user_agent NOT LIKE '%scrapy%'
AND l.user_agent NOT LIKE '%bubing%'
AND l.user_agent NOT LIKE 'Go-http-client/1.1'
AND l.user_agent NOT LIKE '%guzzle%'
AND l.user_agent NOT LIKE '%jetty%'
AND l.user_agent NOT LIKE '%resty%'
``````

It's hard for me to explain or wrap my head, but I think what's going on is that the 11 items that haven't been downloaded yet by humans are effectively excluded from the result by the above conditions. In other words, I think the conditions actually say not to return anything that doesn't match that, and because NULL in Table 2 doesn't match, it eliminates the results where there are has something in table 1 but not in table 2 (and therefore NULL for table 2).

How can I return ALL records from table 1, wp_posts, including data from table 2 when a record matches (and NULL if not), but prefilter table 2 by eliminating the elements where the user agent exclude the bot, etc.?

## How to sort a dataset where each row includes a sequence of strings and integers

I got this type of data:

``````initDataS = Dataset@<|"Count" -> <|ID01 -> 41667 "Train",
ID02 -> 23288 "Tail" + 18379 "Train",
ID03 -> 30907 "Tail" + 10760 "Train",
ID04 -> 34058 "Tail" + 7100 "Train" + 509 "Loop",
ID05 -> 36256 "Tail" + 5411 "Train",
ID06 -> 37548 "Tail" + 3700 "Train" + 419 "Loop"|>|>
``````

I would like to sort it effectively this way:

``````FinalDataS = Dataset@ <|"ID01" -> <|"Train" -> 41667, "Tail" -> 0, "Loop" -> 0|>,
"ID02" -> <|"Train" -> 18379, "Tail" -> 23288, "Loop" -> 0|>,
"ID03" -> <|"Train" -> 10760, "Tail" -> 30907, "Loop" -> 0|>,
"ID04" -> <|"Train" -> 7100, "Tail" -> 34058, "Loop" -> 509|>,
"ID05" -> <|"Train" -> 5411, "Tail" -> 36256, "Loop" -> 0|>,
"ID06" -> <|"Train" -> 3700, "Tail" -> 37548, "Loop" -> 419|> |>
``````

How could I do this?

## How to differentiate a composite function that includes unknown functions?

Let $$f$$ be a $$C ^ 2$$ function of $$mathbb {R} ^ 3$$ at $$mathbb {R}$$.
Let $$Phi$$ be the function of $$(0, infty) times (0, pi) times (0, 2 pi)$$ at $$mathbb {R} ^ 3$$ such as $$Phi (r, theta, phi) = (r sin theta cos phi, r sin theta sin phi, r cos theta)$$.

I want to calculate $$frac { partial f circ Phi} { partial r}$$, $$frac { partial f circ Phi} { partial theta}$$, $$frac { partial f circ Phi} { partial phi}$$.

How to calculate this?
