## How many types of iterative statements are there in PL SQL?

Controlling Loop Iterations: LOOP and EXIT Statements. LOOP statements execute a sequence of statements multiple times. There are three forms of LOOP statements: LOOP , WHILE-LOOP , and FOR-LOOP . For a description of the syntax of the LOOP statement, see “LOOP Statements”.

## What is used for iterative statement?

C++ provides four iteration statements — while, do, for, and range-based for. Each of these iterates until its termination expression evaluates to zero (false), or until loop termination is forced with a break statement.

## What is looping in PL SQL?

The PL/SQL loops are used to repeat the execution of one or more statements for specified number of times. These are also known as iterative control statements. Syntax for a basic loop: LOOP.

## Which statement helps in terminating the PL SQL loop?

You should use EXIT WHEN statement to exit from the Loop. Otherwise the EXIT statement without WHEN condition, the statements in the Loop is executed only once.

## What is difference between procedure and function?

## What is the other name of iterative statement?

In Python, the iterative statements are also known as looping statements or repetitive statements. The iterative statements are used to execute a part of the program repeatedly as long as a given condition is True. Python provides the following iterative statements.

## What are the different types of iterative statement?

7.6 Iteration Statements

• 1 The while Statement. The while statement evaluates a control expression before each execution of the loop body. …
• 2 The do Statement. The do statement evaluates the control expression after each execution of the loop body. …
• 3 The for Statement.

## How many types of iteration are there?

Iteration is another way to express “do something many times”. Most problems can be solved via both recursion and iteration, but one form may be much easier to use than the other. We will study three forms of iteration: tail-recursion, while loops, and for loops.

## Where do we use loops in PL SQL?

PL/SQL for loop is used when when you want to execute a set of statements for a predetermined number of times. The loop is iterated between the start and end integer values. The counter is always incremented by 1 and once the counter reaches the value of end integer, the loop ends.

## How do you stop an infinite loop in PL SQL?

END LOOP; With each iteration of the loop, the sequence of statements is executed, then control resumes at the top of the loop. You use an EXIT statement to stop looping and prevent an infinite loop. You can place one or more EXIT statements anywhere inside a loop, but not outside a loop.

## How do you iterate in PL SQL?

Use the EXIT, FOR, LOOP, and WHILE statements to repeat a series of commands in your PL/SQL program. The cursor FOR loop statement opens a previously declared cursor, fetches all rows in the cursor result set, and then closes the cursor. Use the FOR statement to execute a set of SQL statements more than once.
