to_date() Function Guide

The to_date() function is a commonly used date conversion function in databases. It is used to convert a string into a date data type.

The syntax of the to_date() function is as follows:

convert the string to a date using the specified format

Among them, the string is the string to be converted to a date, and the format is the format of the string.

For example, if we have a string ‘2022-01-01’, we can use the to_date() function to convert it into date type data.

Convert the date ‘2022-01-01’ to the format ‘YYYY-MM-DD’.

This will convert the string ‘2022-01-01’ into a date type data.

The format parameter in the to_date() function can be adjusted to match the format of the string, with commonly used formats including:

1. YYYY: A four-digit year
2. Month
3. Date
4. HH: hours
5. MI: minutes
6. SS: Seconds

By adjusting the format parameter accordingly, different format strings can be converted into date type data.
