Q) What is the difference between executeUpdate and executeQuery Methods?

Rep) We must use executeQuery for executing the ‘select’ statement and executeUpdate for executing ‘non-select’ statement(CURD) etc

CURD is nothing but

C :- Create (insert—->statement)

U :- Update (update—–>statement)

R :- Read (select——->statement)

D :- Delete (delete——>statement)

for Ex: we can provide the code as shown below to perform create operation

Statement stmt=con.createStatement();

String Vsql=”insert into student values(200,’ram’,22,’ampet’);

stmt.executeUpdate(Vsql);
