What is difference between select statement and cursor
Answer Posted / bolearner
The above answer is not so correct.
cursor can fetch rowid, rownum also from table.
The select into cant retrieve more than 1 record in plsql.
But cursor can retrieve more records that can be viewed for modified later in plsql.
Cursors has attributes like open,close,fetch,notfound. Those attributes not applicable in select..into clause.
finally select..into in plsql, just select column values and storing into plsql variable.
