MySQL has many operators and functions that can return strings. For simple functions, that is, receiving string input and returning a string result as the output function, the output character set and verification rules are the same as those of the original input. For example, UPPER (X) returns a string with the same character and proofreading rules as X. Similar functions include INSTR (), LCASE (), LOWER (), LTRIM (), MID (), REPEAT (), REPLACE (

equation for utf8_unicode_ci is true: Token = ss If utf8_unicode_ci sorting is poor for a language, the utf8 character set proofreading rules related to the specific language are executed. For example, utf8_unicode_ci works well in German and French, so you do not need to create special utf8 verification rules for these two languages. Utf8_general_ci is also applicable to German and French, except for 'SS' rather than 'SS. If your application ca

Jakob Jenkov Translator: Simon-sz proofreading: Fang FeiHttp://tutorials.jenkov.com/java-concurrency/index.htmlIn the past single-CPU era, single-tasking can only execute a single program at a point in time. Later in the multitasking phase, computers can perform multitasking or multiple processes in parallel at the same point in time. Although it is not really the "same point in time", but multiple tasks or processes share a CPU, and the operating sys

the operations performed by the database engine in the normal affinity mode. SQLite describes the other two affinity modes, as shown below: Strict affinity mode. In this mode, if you need to convert data storage types between values, the database engine will send an error report and the current statement will run again.In this mode, the data storage type of values is not converted. Values of Different Storage types cannot be compared, but can be compared between integers and real numbers.7. Use
