Is it possible to skip duplicate keys in a BULK INSERT in MySQL?

I have a INSERT...SELECT Instruction that I want to run from TABLE1 to TABLE2 multiple times because the data in TABLE1 changes over time.

I do not expect select's past data to change over time. The selection only returns new data and the same old data from previous queries.

However, due to the unique key limitation for the primary keys, I cannot reinsert old data.

What I want to achieve is kind of INSERT ...ON DUPLICATE KEY UPDATE... but for one INSERT...SELECT,
Skipping the double keys will be enough, but I'm not sure how to do it

php – Format the MySQL DECIMAL data type 1,000.00 and insert it into the database as 1000.00

I am addressing you to the following problem presented to me in a CRUD.
I want you to help me and thank you in advance.
The problem is:
With a function with Javascript I can call up the field "PRICE" of the type DECIMAL (10.2) in the table "PRICES", in which I save, for example, 10000.00 for (ten thousand dollars). The input shows the following format: 10,000.00
If I want to insert this value into the database, it only takes 100.00. So I want to know what I can use to convert the value received in the input and when writing the number into a valid value for the DECIMAL data type of the database.
I show below:

PRICE table:
Field: Decimal price (10.2).


SELECT format(precio,2) FROM precios;

Registrations in the Price field: 500000.00 (with DECIMAL type (10.2)
The query returns the following: 500,000.00

As far as everything is perfect, the input shows me the value 500,000.00
However, if I update the field and enter 600,000.00, it will be saved
like 600.00 and it doesn't save me 600000.00
With the Javascript function, the input shows me 600,000.00, but does not save it for me.
What should I do to save it?
In this format, the entry is made with the help of the Javascript function: 600,000.00 to 600000.00?

The Javascript code used:


This is the input:

php – How to insert forms from one table and insert the ID into another using the checkbox

Hello everyone, I'm something new in forms with PHP and database and I'm trying to use check boxes to select a product. I have 2 tables per call plenitud_productos and another one plenitud_pedidosSince the product table already contains records and prices, I only use them to print this data in the browser. This information is stored in the order table via a form, but with an additional column, namely "Quantity".

This way I print the names and prices. I have different names for this on the form and in the columns of the table in the database. These are:

Type = refers to the name of the product and donation = price.

"> $


1) If I want to use this form, I have to enter the quantity of the product in a text entry and the product via a checkbox, so when I select a product and write the quantity, or the number does not add anything in the table.

These are the insert queries I used:

This is the SQL error when I try to run the query on the database:

#1366 - Incorrect integer value: '$grupo' for column `plenitud_organizador`.`plenitud_pedidos`.`grupo` at row 1

mysql – Punctuation mark of an INSERT statement that uses FROM_UNIXTIME

In one python Environment I have the following variable:


This is a Unix-style time with milliseconds.

In my table, "created_date_time" is defined as the datetime column.

I am trying to use an INSERT statement of the form:

sql_insert_query = "INSERT INTO myTable (id_string, text,
 created_date_time) VALUES ('identifier', 'text_content',

I can't figure out how to underline that. When I run the query as shown above, I get:

"Failed to insert record 1292 (22007): Truncated incorrect DECIMAL value: 'tweet_post_time/1000'

I've tried every variation of single quotes / no quotes I can think of, but I always get errors.

For example if I:

sql_insert_query = "INSERT INTO myTable (id_string, text,
 created_date_time) VALUES ('identifier', 'text_content',

I get:

Failed to insert record 1292 (22007): Truncated incorrect DOUBLE value: 'tweet_post_time'

I went so far as to convert the Unix-like value "1581546697000" as follows:

post_time_mysql = datetime.fromtimestamp(int(post_time)/1000)

and then:

sql_insert_query = "INSERT INTO myTable (id_string, text,
 created_date_time) VALUES ('identifier', 'text_content',

and although

Failed to insert record 1292 (22007): Incorrect datetime value: 'post_time_mysql' for column `myDatabase`.`myTable`.`created_date_time` at row 1

Any ideas / suggestions?

Algorithms – Combine Merge Sorting with Insert Sorting – Time Complexity

I learn algorithms from the CLRS book myself without help. There is an exercise that combines the merge sort {O (n log n)} with the insert sort {O ($ n ^ {2} $)}. If the subarrays in the merge sort reach a certain size "k", it is better to use the insert sort for these subarrays instead of the merge sort. The reason given is that the constant factors in insert sorting make it quick for small n. Can someone please explain that?

It asks us to show that (n / k) sublists with the length k can be sorted by insertion sorting in O (nk) worst case time. I found out from somewhere that the solution to this is O ($ nk ^ {2} / n $) = O (nk). How do we get this part O ($ nk ^ {2} / n $)?

Thanks a lot !

Javascript – Tampermonkey script completely forms from another web … insert values, but do not stay

I use Tampermonkey to create a script that automatically fills in forms that I normally fill out on an ad website.

The problem is that when entering the values ​​of the elements

$("#ad-title").attr("value","VENDO ENANITOS VERDE");
$("#ad-description").html("INTERESADOS CONTACTAR"); 

When you fill out the captcha or submit the form, these values ​​are blank as if you had never filled them out. This is how they stop.
