1.

Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

if such technology wants to be put into application, the biggest problem is the "Impossible Triangle problem"

that is, scalability, decentralization and security cannot be achieved at the same time, and only two of them can be achieved

most of the existing public chain projects in the market are difficult to put into use on a large scale

3. ha-ha. Money fans!! How busy is money? Crazy occupation is the alchemy, more shameless with spies to his home. Come into his house, the money will come!! The strongest mining vehicle is China's (waterway is OK!! Ha ha). Next came the mining trucks with machine guns, which cost twice as much as the allies. However, after the oil refinery in the later stage, it is 1000 at a time!!! Money is divided into concentrate and diamond mine (similar in shape, named by oneself, ha ha), first diamond is delicate. The last conclusion: the glory of the Republic, the glory of China. Mining first in the rare, then in the golden. There are also some categories of gold, there are refiners to pick first Oh!!! Hope to adopt

remember to adopt it

4. The solution is to name the sort method and tell the query analyzer how to sort. Here you need to use a keyword collate
colate, which is explained in SQL Server Books Online as follows:
collate
a clause, which can be applied to database definition or column definition to define collation, or to string expression to apply collation projection

syntax
collate & lt; collation_ name >< br />
< collation_ name > ::= < br /> { Windows_ collation_ name } | { SQL_ collation_ Name}

parameter
collation_ Name

is the name of a collation applied to an expression, column definition, or database definition. collation_ Name can be just the specified windows_ collation_ Name or SQL_ collation_ name < br />
Windows_ collation_ Name
is the collation name of the windows collation. See windows collation name< br />
SQL_ collation_ Name
is the collation name of SQL collation. See SQL collation name

How can we know what the current collation name is? In fact, we can choose the collation name when we create a database (instance), but usually we will default to the original setting and will not change it, So if it is simplified Chinese SQL server will use the simplified Chinese collation by default, and if it is traditional Chinese SQL server will use the traditional Chinese collation by default. When we view the properties of the database (instance), the bottom line of the General tab is the current sorting rule. By default, the collation name in simplified Chinese is: Chinese_ PRC_ CI_ As, and the traditional Chinese collation name is: Chinese_ Taiwan_ Stroke_ CI_ As, so if we have mixed simplified and traditional collation names, we just need to declare which collation you want to use for comparison. For example, for the above SQL statement, the following two methods can solve the problem of error prompt
select table1. *, Table2.*
FROM Table1
INNER JOIN Table2 ON Table2.FK = Table1.PK COLLATE Chinese_ PRC_ CI_ AS

SELECT Table1.*,Table2.*
FROM Table1
INNER JOIN Table2 ON Table2.FK = Table1.PK COLLATE Chinese_ Taiwan_ Stroke_ CI_ As

talked about how to solve the problems caused by sorting rules conflict for a long time. If you are still interested, please post the concept of sorting rules in SQL server online series for you to share, so that you can find it again:
Microsoft & # 174; SQL Server™ 2000 supports multiple collations. Sorting rules control the correct use of languages (such as Macedonian or polish) or alphabets (such as Latin1, the Latin alphabet used in Western European languages)_ General) character< Each SQL Server collation specifies three properties:

the sort order used for Unicode data types (nchar, nvarchar, ntext). Sort order defines the sort sequence of characters, and the method of character value in comparison operation

used for the sort order of non Unicode character data types (char, varchar, and text)

the code page used to store non Unicode character data

indicates that code pages corresponding to unicode data types (nchar, nvarchar, ntext) cannot be specified. The double byte bit pattern used for Unicode characters is defined by the Unicode standard and cannot be changed

SQL Server 2000 collation can be specified at any level. When you install an instance of SQL Server 2000, you can specify the default collation for that instance. Each time you create a database, you can specify the default collation for that database. If no collation is specified, the default collation of the database is the default collation of the instance. Whenever you define character columns, variables, or parameters, you can specify the collation for these objects. If no collation is specified, the objects are created using the default collation for the database

if all users of the SQL server instance use the same language, you should choose a collation that supports that language. For example, if all users speak French, select the French collation

if users of SQL server instances use multiple languages, they should choose the sort rule that can provide the best support for multilingual requirements. For example, if the user generally speaks Western European, select Latin1_ General collation. When supporting multilingual users, it is most important to use the Unicode data types nchar, nvarchar and ntext for all character data. Unicode is designed to eliminate code page conversion difficulties for non Unicode char, varchar, and text data types. Because the collation defines the sort order used for comparison operations and the sort of Unicode characters, the collation still makes a difference when all columns are implemented with Unicode data types. Even when using Unicode data types to store character data, you should choose a collation that supports most users to prevent using non Unicode data types to implement columns or variables

sql server collation defines how database engine stores and operates characters and Unicode data. However, when the data is moved into the application, the sorting and comparison of characters in the application will be controlled by the windows locale selected on the computer. The collation of character data used by an application is one of the items controlled by the windows locale, which also defines other items, such as number, time, date, and currency formats. For Microsoft Windows NT & # 174; 4.0、Microsoft Windows® 98 and Microsoft Windows 95, you can use & quot; Regional settings & quot; The application specifies the windows locale. For Microsoft Windows 2000, you can use & quot; Control panel & quot; & quot; Regional Options & quot; The application specifies the locale. For more information about windows locale, see the Microsoft Web site MSDN & # 174; Developing international software for Windows 95 and windows NT 4.0 in the

multiple collations can use the same code page for non Unicode data. For example, code page 1251 defines the Cyrillic character set. Multiple collations, such as Cyrillic_ General, Ukrainian, and Macedonian). Although these collations all use the same bit set to represent non Unicode character data, the collation and comparison rules used in processing dictionary definitions are slightly different, and dictionary definitions determine the correct sequence of characters associated with the collation in a language or alphabet

because SQL Server 2000 collations control the Unicode and non Unicode sort order, there is no problem caused by specifying different collations for Unicode and non Unicode data. In previous versions of SQL server, code page number, character sort order, and Unicode sort rule were specified separately. Earlier versions of SQL server also supported a different number of sort orders per code page, and provided sort orders for some code pages that were not available in the windows locale. In SQL Server 7.0, you can also specify a Unicode sort order other than the sort order selected for non Unicode data. This causes the sort and compare operations to return different results when using Unicode data relative to non Unicode data.

5. It's very simple; First, take the motorcycle to Lintou bus station of national highway 105 (tell the driver which way to go to Guangzhou!) Then, wait for the bus to Guangzhou Tianhe passenger station, about 15 to 20 minutes a bus! Good luck

6.

Take a long-distance bus from Beijiao transportation center terminus (< / u > 06:50-19:30 every 10-15 minutes) to humen bus terminal in Dongguan, and get off

the whole journey takes about 1 hour and 25 minutes

7.

As of February 2017, Foshan Beijiao has taken a bus to Dongguan People's Park. It is recommended to take a bus to Dongguan bus station first and then transfer to the people's Park by bus

bus line: No.28, the whole journey is about 6.2km

1. Walk about 440m from Dongguan bus terminal to Dongguan bus terminal

2. Take No.28, pass 7 stops, and reach people's Park Station (or take no.lg1)

8. We can't know where to trade the attack Telecom issue.
