salamat po ng marami . gets ko na poUse the ff command: select <column> from <table> <where condition = value> . Yung <where condition = value> ay optional, just for filtering.
e.g.
a. list all grades in the student table
select grade from studentTbl;
b. list grade of student with name that is 'abc' in the student table
select grade from studentTbl where name = 'abc';
c. list all columns and their value in the student table
select * from studentTbl;
