Derived merge bugs resolved in mysql8

Any Derived_merged bugs resolved in mysql8? Is it optimal if I use Derive_merged = on in MySQL 8.0.11?

By Derived_merged = we give an invalid query output when it will be used with order by or group by?

I know this question has already been asked, but the answer still does not satisfy my thirst for knowledge.

For the moment, everything is in confusion and I would like a clear answer so that generations of people can benefit from this question. Thank you !

Unable to merge Facebook page because "Merge is pending"

I am in the process of merging duplicate Facebook pages but I meet the following number of several pages:

When I request a merger, I receive an error message saying that the merge can not be performed because a merge is pending.

However, I'm pretty sure it's the first merger application (at least for some pages) and when I look in the Page Settings> Page Support Inbox I do not see any merger requests pending.

I notice that many people have been confronted with this situation, but I have found no reason or solution to remedy it. Do you have an idea?

Triggers corrupted merge replication

I have merge replication (SQL Server 2014) and a table that has 3 triggers that monitor deletion, insert, and update.
All triggers are after trigger not instead of.

I update the value of one side and do not put it on the second server. When I turn off triggers, everything works.
insert and delete does not work as well.
Thoughts ?

Hard Disk – Can not Merge Partitions or Reinstall OSX

I have an SSD drive in MacBook Pro mid-2009 with 2 partitions and I'd like to perform a new installation.

So .. using Disk Utility, I deleted both partitions (OS X Extended – Journaled). Until here everything is fine. Now I wanted to merge the two partitions and in doing so I have the message "The operation failed. Can not unmount the disk". When I click done, I see that both partitions are dismounted.

The "Instant Error" Macintosh 1 hard disk volume is not logged in. To enable logging, click Enable Logging on the File menu. I did it but no luck. Always the same mistake.

I have therefore abandoned the merger of partitions and tried to install OS X. But no luck … there is no partition to select during the installation process. Only the recovery partition is visible.

I have tried to unmount terminal disks using diskutil, but none of the partitions can be dismounted.

Help me, please! Thank you.

javascript – How to merge an object in IE 11

I have the following object board:

objs[0] = {Name: "ABC"};
objs[1] = {Roll: 123}

I'm trying to do it as follows:

Objs {
Name: "ABC",
Roll: 123
}

I've tried doing it with the following code:

var Objs = [{
  Name: "ABC"
}, {
  Roll: 123
}];

console.log (
Object.assign.apply (null, [{}].concat (Objs)) // 1
)
or

console.log (
Object.assign ({}, ... Objs) // 2
)

The problem is that it does not work in IE 11.

I receive the errors:

Error for 1: Unable to get property on & # 39; of an undefined or nil reference

Error for 2: The object does not support the property or method & # 40; assign & # 39;

Any suggestions on how I should merge the object into IE 11?

Merge with pandas in python

I have two dataframes: products and sales. On the product: Enter the code and the name of the product in the "product" column. On sale, I have the codes sales_code, sales_cod, order_data and product_code.

The detail is that by joining with pandas.merge I can not display the products:

df_sales = pd.read_csv ("sales.csv", sep = ";")

df_products = pd.read_csv ("Products.csv", sep = ";", encoding = "iso-8859-1")

vp = df_vendas.merge (right = df_products, left_on = "sales_code", right_on = "code", comment = left, left_index = False, right_index = False , copy = True)  

The product file contains only 9 products and in the merge, only the products appear in the first 9 sales, but the product code appears on all lines of the vp data frame.

How can I display the product on all lines of the new data frame, as we do in an SQL, for example?

software – How to create two layers in "Gimp" and merge them into one?

It's easy. First, if the Layers window does not open, go to the Windows menu and choose it. You do not need that, but it is practical. This is a small "utility" window that usually floats near the right side of your screen. And open your file, if you have not done it yet. With this window open, you can click on the existing layer in the image (probably Context), then click the Duplicate Layer button below – or press Ctrl-Shift-D. Then, to merge this layer, go to the Image menu and select Merge Visible Layers (Ctrl-M). You can also use Flatten the image. Alternatively, if you have more than two layers, there is Fusion in the Layers menu, which does what it says.

By the way, Gimp offers fully customizable keyboard shortcuts. Look at the bottom of the Edit menu for keyboard shortcuts (may be mixed with the preferences of some older versions of Gimp). That way, if something is not shortcut, or if you do not like the fault, you can fix it.
