SELECT STATEMENT CONTAINS PARTICULAR STRUCTURE AND SELECT
QUERY RESULT SET CONTAINS ROWID,ROWNUM.

CURSOR DOESN'T CONTAIN STRUCTURE AND IT IS
VIRTUAL(CONTEXAREA)MEANS NO ROWID,NO ROWNUM.

Answer / 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.

Answer / akash

Using select..into statement u cannot fetch more than 1 rows.
Beside naming the same select statement as cursor explicitly allows user to options like OPEN,CLOSE,FETCH.

SELECT emp_num, years, SUM(salary) FROM sales UNION ALL SELECT emp_id, SUM(takehomepay) FROM marketing What error is present in the sample code above? 1. Queries being combined with the UNION ALL statement are not allowed to have SELECT lists with a different number of expressions. 2. You are not allowed to use aggregate functions within two queries joined by a UNION ALL statement. 3. The UNION ALL statement incorrectly combines the "years" result from the first query with the "SUM (takehomepay)" result from the second query. 4. Unless the UNION ALL statement is replaced with a UNION statement, the queries will return duplicates. 5. The "emp_id" column from the second query must be renamed (or aliased) as "emp_num" so that it corresponds to the column name from the first query. Otherwise, the queries will not execute.
