Sql injection. On vulnerable servers you can use certain codes to get information from a database. An example is
"
"SELECT
Firstname ' ' Lastname
FROM
Users
"
"
This would try to find the firstname and lastname from the database named Users
Btw there is suppose to be the character you mentioned around the " ' ' "
