Syntax of SQL UPDATE Date

To update a date and time field in SQL, you should use the following query syntax:

UPDATE Table_Name  
SET Column_Name = 'YYYY-MM-DD HH:MM:SS'  
WHERE Id = value;

This query updates the specified column with a new date and time value for the row that matches the given Id.

Example: Updating a Date and Time Field

Let’s assume we have a table named EmployeeRecords where we want to update a date and time field.

Table: EmployeeRecords

Id	EmployeeName	JoiningDate
1	Aman Verma	2023-05-10 09:30:00
2	Neha Sharma	2023-06-15 11:00:00

Now, if we want to change the JoiningDate of the employee with Id = 1, we can execute the following SQL statement:

UPDATE EmployeeRecords  
SET JoiningDate = '2024-02-20 08:45:00'  
WHERE Id = 1;

Updated Table: EmployeeRecords

Id	EmployeeName	JoiningDate
1	Aman Verma	2024-02-20 08:45:00
2	Neha Sharma	2023-06-15 11:00:00

Important Notes:

• SQL automatically appends 00:00:00.000 if no time is specified in a DATETIME column.
• The WHERE clause is essential to ensure only the intended record is updated.
• Always double-check your query before executing it to avoid accidental data loss.
