We can see that employee number 999901 is John Smith.

So, we can create a query with the following update statement: UPDATE “Employees”, SET, and then assign the value of the string “Stella” to the “first name” column, the string “Parkinson” to the “last name” column, the 31 of December 1990 to “birth date”, and “F” to “gender”.

So, let’s exit this connection and then reconnect, typing the password once again! In the previous post about SQL INSERT Statement, we inserted an employee under the number of 9-9-9-9-0-1, remember? The syntax to adhere to is UPDATE table name, the keyword SET, column names and the respective values assigned to them, and finally – WHERE, and a certain condition, or set of conditions, that must be satisfied.

Now, we are ready to dive into the UPDATE statement. By using this code structure, SQL will change the record or records satisfying the WHERE condition, updating the old values of the columns listed with the new ones.

Note that we did not update the “hire date” column value, right? This is fine, as we do not have to update each value of the record of interest. With a different birthdate and gender, although with the same hire date.

Of course, we can still say we have updated the specific record! After that, we will select the same employee through the employee number once again. Please note the following feature of the UPDATE statement.

This means if you have already used COMMIT 10 times, ROLLBACK will have an effect on the last execution you have performed.

After that moment, even if you run the ROLLBACK clause 20 times, you can get to the state of only the last COMMIT.

On the right-hand side, scroll down to get to the box that says, “Safe Updates”.

Through the ticking of this option, the software could prevent you from losing significant amounts of data or some of the changes you made earlier.

You cannot restore data to a state corresponding to an earlier COMMIT.
