Some examples
Note: you can specify the PATH but this project was build in intellij IDEA, so the txts are in the same path as the project
Note: The alias only work with "=" because of lack of time for the implementation, because this was a project for university

• select * from pruebas ; - where pruebas is the name of the .txt and its not necessary the ; in the query
• Select Nombre from pruebas where Nombre!=Rebeca
• update pruebas set Matricula=1 where Nombre=Rebeca
• delete from pruebas where Matricula<1730042
• delete from pruebas where Matricula>1730042
• select pruebas.Nombre as pruebas, pruebas1.Matricula as pruebas1 from pruebas,pruebas1 where pruebas.Matricula=pruebas1.Matricula
• insert into pruebas (Nombre,Matricula) values("Test",100)

It read a txt with information with "," as a data separator and ";" as a separator for the label in the first line

example from pruebas.txt:
Nombre ApellidoP ApellidoM Matricula;
Rebeca,Gonzalez,Batista,1730042
Angel,Sepulveda,Lozada,1430382
