Can anyone tell me what the double quotes are for in the table name in a query? for example: select * from "student" Where name= 'Stefany'
what the two quotes of the student table do differently?

Double quotes are standard ANSI delimiters for identifiers, when you run the instruction select * from "aluno"
, will return the same data as an instruction select * from aluno

In ANSI SQL, double quotes are used in object names (for example, tables) they allow them to contain characters not otherwise permitted or to be equal to reserved words.

Depends on the database engine. But in general double quotes delimit database object identifiers and single quotes delimit strings and/or dates.
