You can perform a search for an age less than 12 from this search screen. He will no longer be seeing children, so anyone under 12 needs to be removed from the database. Let's say the doctor in our example database gets a new partner who is a pediatrician.
Selecting the X will remove the entry, or to delete multiple entries, you can check the boxes on the far left and then hit the red X at the bottom of the page.Īnother thing you can do is select the search tab.
Next to each entry, you will see a red X. One way to remove entries is by then choosing the browse tab on the right. That being said, when you are in phpMyAdmin, you can remove information a number of ways. You should be very careful when doing this because once it is gone, it's gone. Specify both the column names and the values to be inserted: INSERT INTO tablename (column1, column2, column3. Often, you need to remove old information from your database. The important part of this command is WHERE, which ensures that the information is only updated for Peggy and not for every user in the database.
MYSQL SYNTAX INSERT VALUE UPDATE
What this does is update the table "people" by setting new values for age, date, and height. UPDATE people SET age = 7, date = " 16:21:00", height = 1.22 WHERE name = "Peggy" You have to be very careful when updating records this way and double check your syntax, as it is very easy to inadvertently overwrite several records. You can also do this through the query window or command line. You can now update her information as shown. Next to Peggy's name you will see a pencil icon this means EDIT. If you are using phpMyAdmin, you can do this by selecting your database on the left (in our case people) and then choosing "Browse" on the right. Let's say that Peggy (from our example) came in for a visit on her 7th birthday and we want to overwrite her old data with her new data. Often, it is necessary to change the data you have in your database.
