Example of PL/SQL GOTO statement

Let’s take an example of PL/SQL GOTO statement.

After the execution of above code, you will get the following result:

value of a: 30 value of a: 31 value of a: 32 value of a: 33 value of a: 34 value of a: 36 value of a: 37 value of a: 38 value of a: 39 value of a: 40 value of a: 41 value of a: 42 value of a: 43 value of a: 44 value of a: 45 value of a: 46 value of a: 47 value of a: 48 value of a: 49  Statement processed.
