Given a date in JavaScript DateTime format and the task is to convert this time into MySQL DateTime format using JavaScript.

Approach:

Use date.toISOString() function to convert the date object into string ISO format i.e. YYYY-MM-DDTHH:mm:ss.sss or ±YYYYYY-MM-DDTHH:mm:ss.sss format.
Use slice() method to extract the part of a string.
Use replace() method to replace the ‘T’ character with space ‘ ‘.

Example 1: In this example, the JavaScript DateTime object is converted into MySQL DateTime (UTC format) by using slice() and replace() method.

Javascript

function GFG_Fun() {
    let date = new Date();
    console.log("MySQL datetime - " +
        date.toISOString().slice(0, 19).replace('T', ' '));
}
 
GFG_Fun();

Output

MySQL datetime - 2023-06-18 03:27:13

Example 2: This is same as previous example but with a different approach and time is in IST, the JS datetime is converted to MySQL datetime by using slice() and replace() method.

Javascript

function GFG_Fun() {
     
    let date = new Date();
     
    console.log("MySQL datetime - " +
            date.toISOString().split('T')[0] + ' '
            + date.toTimeString().split(' ')[0]);
}
 
GFG_Fun();
