Updating databases in

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.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.We must be very careful when using COMMIT and ROLLBACK – in other words, when we are changing the state of our data set.Please note that it will be very hard to practice these statements unless we switch off the following feature of Workbench.Stay focused for another interesting feature we will discuss next.

On the left-hand side of the window that pops up, choose the “SQL Editor” section.

Had we used a non-existent condition in the WHERE clause (for instance, an employee number of 999909), My SQL would have allowed the execution of the query, given that the SQL syntax is correct.

Nevertheless, nothing would have happened – the statement would have worked, affecting 0 rows, because the data table doesn’t contain an employee with such a number at the moment of the query’s execution.

This is only recommended for systems unable to use Geo IP Update.
