In some cases, we may want to update table data using update sql statement. Lets see how can we update.
The table which I am using to update record is as below. The table name is emp_info
| emp_id | emp_name | emp_age |
|---|---|---|
| 1 | Raj | 22 |
| 2 | Rahul | 24 |
| 3 | Vivek | 26 |
| 4 | Ajay | 28 |
| 5 | Suraj | 29 |
In the above table, lets say, I want to update the emp_name from Vivek to Birju whose id is 3.
If you have understanding of mysqli insert statement then following code is just a piece of cake for you. I have already discussed about insert statement. So check that tutorial.
Update Record
$conn=mysqli_connect(‘localhost’,’root’,”,”employee_db);
$sql=”update emp_info set emp_name=’Birju’ where id=3″;
if(mysqli_query($conn,$sql)){
echo “Updated successfully”;
}else{
echo “Failed to Update”;
}
Output: Updated uccessfully
