Sqlserver 常用日期时间函数
Sqlserver中经常要操作一些时间类型的字段转换,我又不太记得住,记在这里方便自己以后要用的时候寻找,望对大家也有帮助.
MS SQL Server中文版的预设日期datetime格式是yyyy-mm-dd hh:mm:ss.mmm长短日期格式
代码如下:
--短日期格式:yyyy-m-d
SELECT REPLACE(CONVERT(varchar(10),getdate(),120),N'-0','-')
--长日期格式:yyyy年mm月dd日
SELECT STUFF(STUFF(CONVERT(char(8),getdate(),112),5,0,N'年'),8,0,N'月')+N'日'
--短日期格式:yyyy年m月d日
SELECT DATENAME(Year,getdate())+N'年'+CAST(DATEPART(Month,getdate()) AS varchar)+N'月'+DATENAME(Day,getdate())+N'日'
--完整日期+时间格式:yyyy-mm-dd hh:mi:ss:mmm
SELECT CONVERT(char(11),getdate(),120)+CONVERT(char(12),getdate(),114)
CONVERT
代码如下:
Select CONVERT(varchar(100), GETDATE(), 0) : 05 16 2006 10:57AM
Select CONVERT(varchar(100), GETDATE(), 1) : 05/16/06

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.

Article discusses strategies for handling large datasets in MySQL, including partitioning, sharding, indexing, and query optimization.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.
