mysql to_date

MySQL does not have a built-in TO_DATE function like some other databases. Instead, MySQL offers the DATE_FORMAT function that allows you to convert a string to a date format.
Here's an example of how you can use DATE_FORMAT to convert a string to a date in MySQL:
```
SELECT STR_TO_DATE('2022-01-30', '%Y-%m-%d') AS date;
```
In this example, the STR_TO_DATE function is used to convert the string '2022-01-30' to a date format using the '%Y-%m-%d' format specifier. You can customize the format specifier based on your specific date string.
Keep in mind that MySQL expects the input string to match the specified format exactly, otherwise it will return NULL.

mysql str_to_date
mysql str_to_date 是用来将字符串转换为日期格式的函数。它的语法如下:
```
STR_TO_DATE(str, format)
```
其中,str 是要转换的字符串,format 是日期格式字符串。例如,如果要将字符串 '2022-01-01' 转换为日期格式,可以使用以下语句:
```
SELECT STR_TO_DATE('2022-01-01', '%Y-%m-%d');
```
输出结果为:'2022-01-01'
mysql 与oracle to_date
在MySQL中,并没有to_date()函数。to_date()函数是Oracle数据库中的一个函数,用于将字符串转换为日期格式。如果你想在MySQL中进行日期格式的转换,可以使用STR_TO_DATE()函数。STR_TO_DATE()函数的用法与to_date()函数类似,可以将指定的字符串按照指定的格式转换为日期类型。例如,如果要将字符串'2011-09-20 08:30:45'转换为日期格式,可以使用以下语句:
STR_TO_DATE('2011-09-20 08:30:45', '%Y-%m-%d %H:%i:%s')
其中,'%Y-%m-%d %H:%i:%s'表示日期的格式,具体的格式说明可以参考MySQL的官方文档。请注意,MySQL和Oracle在函数的名称和用法上可能存在差异,所以在使用函数时需要根据具体的数据库来选择合适的函数。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
