Answer Posted / ratheesh.a
executeQuery(): This is a method/function used in jdbc
programs. this method will return a 'Resulset' object.
Through this method we can access the result of the query
Usually the Select query is used here..
executeUpadte(): This method is mainly used for updating
queries.. such as 'insert,update,delete' etc... returns an
integer value which shows how many rows are updated...
execute() :What ever the sql queries we are giving in the
other 2 methods can also be include here
This will return a boolean value if it returns 'true' means
query executed successfuly else not..
