In MySQL, the methods to set the number of decimal places to 1 are: 1. Use the DECIMAL data type, the syntax is DECIMAL(precision, scale), where scale specifies the number of decimal places. 2. Use the CAST() function, with the syntax CAST(number AS DECIMAL(precision, scale)), to convert a decimal to a value with a specified number of decimal places.
How to set the number of decimal places to 1 in MySQL
In MySQL, you can use the following two methods Method sets the number of decimal places to 1:
Method 1: Using the DECIMAL data type
The DECIMAL data type allows you to specify the number of decimal places. To set the number of decimal places to 1, use the following syntax:
<code>DECIMAL(precision, scale)</code>
Where:
-
precision
Specifies the total number of digits (including decimal places) -
scale
Specify the number of decimal places
To set the number of decimal places to 1, use the following syntax:
<code>DECIMAL(10, 1)</code>
This will create a DECIMAL data type with 10 total digits and 1 decimal place.
Method 2: Use the CAST() function
You can also use the CAST() function to convert an existing decimal to a value with 1 decimal place. The syntax is as follows:
<code>CAST(number AS DECIMAL(precision, scale))</code>
For example, to convert the number 123.456 to a value with 1 decimal place, use the following syntax:
<code>CAST(123.456 AS DECIMAL(10, 1))</code>
This returns a DECIMAL value with a value of 123.5.

本篇文章给大家带来了关于mysql的相关知识,其中主要介绍了关于架构原理的相关内容,MySQL Server架构自顶向下大致可以分网络连接层、服务层、存储引擎层和系统文件层,下面一起来看一下,希望对大家有帮助。

mysql的msi与zip版本的区别:1、zip包含的安装程序是一种主动安装,而msi包含的是被installer所用的安装文件以提交请求的方式安装;2、zip是一种数据压缩和文档存储的文件格式,msi是微软格式的安装包。

方法:1、利用right函数,语法为“update 表名 set 指定字段 = right(指定字段, length(指定字段)-1)...”;2、利用substring函数,语法为“select substring(指定字段,2)..”。

在mysql中,可以利用char()和REPLACE()函数来替换换行符;REPLACE()函数可以用新字符串替换列中的换行符,而换行符可使用“char(13)”来表示,语法为“replace(字段名,char(13),'新字符串') ”。

转换方法:1、利用cast函数,语法“select * from 表名 order by cast(字段名 as SIGNED)”;2、利用“select * from 表名 order by CONVERT(字段名,SIGNED)”语句。

在mysql中,可以利用REGEXP运算符判断数据是否是数字类型,语法为“String REGEXP '[^0-9.]'”;该运算符是正则表达式的缩写,若数据字符中含有数字时,返回的结果是true,反之返回的结果是false。
