Updating fetch in plsql

For UPDATE and DELETE operations, the cursor identifies the rows that would be affected.In PL/SQL, you can refer to the most recent implicit cursor as the SQL cursor, which always has attributes such as %FOUND, %ISOPEN, %NOTFOUND, and %ROWCOUNT.I fully endorse this approach and both use and reiterate it daily to my teams.Here are but a few of the benefits of this brand of thinking: So, should we always use SQL over PL/SQL if the SQL language permits us to do so?The following picture describes steps that you need to follow when you work with a PL/SQL cursor: Once the cursor is open, you can fetch data from the cursor into a record that has the same structure as the cursor.Instead of fetching data into a record, you can also fetch data from the cursor to a list of variables.

In this chapter, we will discuss the cursors in PL/SQL. A cursor holds the rows (one or more) returned by a SQL statement.As you can probably guess, there are situations where using PL/SQL can be the better option.Such as in life, in technology the only guarantee is that there are no guarantees.The SQL cursor has additional attributes, %BULK_ROWCOUNT and %BULK_EXCEPTIONS, designed for use with the FORALL statement.The following table provides the description of the most used attributes − Select * from customers; ---- ---------- ----- ----------- ---------- | ID | NAME | AGE | ADDRESS | SALARY | ---- ---------- ----- ----------- ---------- | 1 | Ramesh | 32 | Ahmedabad | 2000.00 | | 2 | Khilan | 25 | Delhi | 1500.00 | | 3 | kaushik | 23 | Kota | 2000.00 | | 4 | Chaitali | 25 | Mumbai | 6500.00 | | 5 | Hardik | 27 | Bhopal | 8500.00 | | 6 | Komal | 22 | MP | 4500.00 | ---- ---------- ----- ----------- ---------- DECLARE total_rows number(2); BEGIN UPDATE customers SET salary = salary 500; IF sql%notfound THEN dbms_output.put_line('no customers selected'); ELSIF sql%found THEN total_rows := sql%rowcount; dbms_output.put_line( total_rows updating fetch in plsql-64updating fetch in plsql-78updating fetch in plsql-61
