Because MyISAM saves the exact number of rows in the table InnoDB does not save the exact number of rows in the table, it requires progressive scan statistics, it is very slow COUNT with WHERE The same , InnoDB also locks the table Lock Only table locks are supported S

Using MySQL will of course have access to the MySQL storage engine, which you will see when creating a new database and creating a new data table.MySQL default storage engine is MyISAM, other commonly used is innodb.What kind of storage engine is better? This question is inconclusive and needs to be measured in terms of your needs and circumstances. Therefore, th

and Localstoragesessionstorage is used to store data locally in a session, which can only be accessed by a page in the same session and destroyed when the session ends. So sessionstorage is not a persistent local store, only session-level storage.While Localstorage is used for persistent local storage, data is never available until the data is actively deleted. The concept of Web storage is similar t

Time zone conversion, which transforms the current time zone when it is stored, and then converts it back to the current time zone.Datetime8 bytes stored, actual format stored, time-zone independent, DateTime retrieves and displays datetime values in ' yyyy-mm-dd HH:MM:SS ' format.

Θxamarin Ecological System problemsObviously, the Xamarin community is much smaller than iOS or Android. Therefore, finding an experienced Xamarin developer can be a challenge. Although the platform is growing with the support of

index also leads to an increase in storage-space resource consumption. How to determine if you need to create an index After understanding the pros and cons of indexing, how do we determine if an index should be created? In fact, there is not a very clear law that clearly defines what fields should be indexed, and what fields should not be indexed. Because t

Android with the IOS the pros and cons CompareComparing Android to IOS is a personal issue. like me, I use two of them. I know the pros and cons of these two platforms. So, I decided to share my views on these two mobile platforms. Also, then talk about my impressions of the new Ubuntu mobile platform and its advan

. Paul Greeberg, an expert in ERP and CRM, wrote that "I have always really disliked BYD products, not just in the design and lack of functionality." ”However, it is still not possible for SAP to define resources that are open to midsize enterprises. Because SAP's business is a huge and complex ERP system for large multinational companies. Focusing on these complex businesses is a challenge, and it's no easy matter to focus on midsize businesses. As a result, SAP was unable to open its resources

Other encodings are optimized for this encoding, such as UTF-8,GBK.UTF-8: Compression and refinement of Unicode (numbers, letters and ASCII codes using 8-bit encoding to store), Python3 default encoding used, European characters: 2 bytes, 16-bit storage; Chinese characters: 3 bytes, 24 bit storageSummary: Python3 default encoding is UTF-8, enco

Array Advantages: Fast query, if you know the index can quickly access the disadvantage: Delete slow, size fixed ordered array advantages: Faster than unordered array lookup disadvantage: Delete and insert slow, size fixed stack advantages: Provide last-in-first-out access method disadvantage: Access to other items is slow queue advantages: Provide first-in-out access method disadvantage: access to other The items are slow. List Advantages: Quick Insert, delete fast disadvantage: find slow (each

null values in the database, and NULL is always the first in ascending order, so for different partition types, The MySQL database also handles null differently. For a range partition, if NULL is inserted into the partition column, the MySQL database puts the value in the leftmost partition, noting that if the partition is deleted, all content under the partition is deleted from the disk, the null partition is removed, and the null value is then deleted. To use null under the list partition, yo
