sql server convert()函数使用方法详解
本文章来给各位朋友介绍sql server convert()函数使用方法,CONVERT() 函数是把日期转换为新数据类型的通用函数和CONVERT() 函数可以用不同的格式显示日期/时间数据。
例
下面的脚本使用 CONVERT() 函数来显示不同的格式。我们将使用 GETDATE() 函数来获得当前的日期/时间：
| 代码如下 | 复制代码 |
|
CONVERT(VARCHAR(19),GETDATE()) 结果类似： Dec 29 2008 11:45 PM |

SQLserver中用convert函数转换日期格式2008-01-15 15:51SQLserver中用convert函数转换日期格式
SQL Server中文版的默认的日期字段datetime格式是yyyy-mm-dd Thh:mm:ss.mmm
例如:
getdate()
2004-09-12 11:06:08.177
整理了一下SQL Server里面可能经常会用到的日期格式转换方法:
举例如下:

4 104 德国 dd.mm.yy
5 105 意大利 dd-mm-yy
6 106 - dd mon yy
7 107 - mon dd, yy
8 108 - hh:mm:ss
- 9 或 109 (*) 默认值 + 毫秒 mon dd yyyy hh:mi:ss:mmmAM（或 PM）
10 110 美国 mm-dd-yy
11 111 日本 yy/mm/dd
12 112 ISO yymmdd
- 13 或 113 (*) 欧洲默认值 + 毫秒 dd mon yyyy hh:mm:ss:mmm(24h)
14 114 - hh:mi:ss:mmm(24h)

关于Emaker中字段的格式转换和字段间的运算代码可以加到属性里的“格式转换（读出）”和“格式转换（写入）”
，table字段设定里的“字段”位置也可以灵活加函数。比如：'AF'+ID 或者ID+'/'+PWD ,convert(varchar(50),F1)
,convert(int,%)-19110000 (读出)
convert(char(8),convert(int,%)+19110000) （写入）
实现行的合计运算等等。加入：%系统变量%，则是调用在Emaker 系统中设定的系统变量。
可以使用的 style 值：
| Style ID | Style 格式 |
|---|---|
| 100 或者 0 | mon dd yyyy hh:miAM （或者 PM） |
| 101 | mm/dd/yy |
| 102 | yy.mm.dd |
| 103 | dd/mm/yy |
| 104 | dd.mm.yy |
| 105 | dd-mm-yy |
| 106 | dd mon yy |
| 107 | Mon dd, yy |
| 108 | hh:mm:ss |
| 109 或者 9 | mon dd yyyy hh:mi:ss:mmmAM（或者 PM） |
| 110 | mm-dd-yy |
| 111 | yy/mm/dd |
| 112 | yymmdd |
| 113 或者 13 | dd mon yyyy hh:mm:ss:mmm(24h) |
| 114 | hh:mi:ss:mmm(24h) |
| 120 或者 20 | yyyy-mm-dd hh:mi:ss(24h) |
| 121 或者 21 | yyyy-mm-dd hh:mi:ss.mmm(24h) |
| 126 | yyyy-mm-ddThh:mm:ss.mmm（没有空格） |

When might a full table scan be faster than using an index in MySQL?
Apr 09, 2025 am 12:05 AM
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.

Can mysql and mariadb coexist
Apr 08, 2025 pm 02:27 PM
MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.
RDS MySQL integration with Redshift zero ETL
Apr 08, 2025 pm 07:06 PM
Data Integration Simplification: AmazonRDSMySQL and Redshift's zero ETL integration Efficient data integration is at the heart of a data-driven organization. Traditional ETL (extract, convert, load) processes are complex and time-consuming, especially when integrating databases (such as AmazonRDSMySQL) with data warehouses (such as Redshift). However, AWS provides zero ETL integration solutions that have completely changed this situation, providing a simplified, near-real-time solution for data migration from RDSMySQL to Redshift. This article will dive into RDSMySQL zero ETL integration with Redshift, explaining how it works and the advantages it brings to data engineers and developers.
