SQL CONTINUE Statement

The SQL Continue statement is very useful to control the flow of a SQL While loop. Generally, we use this Continue statement inside the While loop. If the execution finds the SQL continue statement inside the While loop, it will stop executing the current loop iteration and starts the new iteration from the beginning.

For example, If we have 15 statements inside the loop. And we want to skip executing few statements (statement 2 — statement 6, and statement 11 — statement 14) when a specific condition is True. Otherwise, it has to run all the 15 statements inside the loop. In this situation, we can place the SQL IF ELSE or SQL ELSE IF to check for the condition, and within the if block puts the continue statement in SQL Server. If the condition is True, it will stop executing statements 2 to 6 and 11 to 14; otherwise, it will run statements from 1 to 15.

SQL CONTINUE Syntax

The syntax of the SQL Server Continue Statement is

CONTINUE;

SQL CONTINUE Statement example

In this query, We are going to use the SQL Continue statement inside the While loop to control the loop iteration.

-- SQL CONTINUE Statement Example
DECLARE @Val INT
SET @Val = 1

WHILE @Val <= 10
	BEGIN
		IF (@Val = 3 OR @Val = 7)
		BEGIN
			PRINT 'Skipped By Continue Statement = ' + CONVERT(VARCHAR, @Val)
			SET @Val= @Val + 1
			CONTINUE
		END
		PRINT 'Tutorial Gateway Views = ' + CONVERT(VARCHAR, @Val)
		SET @Val= @Val + 1
	END
PRINT 'This statement is Coming from Outside the While Loop'
GO
SQL CONTINUE Statement 1

Within this SQL continue statement example, First, we created one variable called @Val and initialized it to 10 using the following statement

DECLARE @Val INT
SET @Val = 1

Within the While loop, we check for the condition whether @Val is less than 10 or not. I suggest you to refer SQL While Loop article to understand the iteration process.

WHILE @Val <= 10

Inside the While loop, we placed SQL IF ELSE to test whether @Val is equal to 3 or 7 (IF (@Val = 3 OR @Val = 7)). If the condition is false, it will skip the SQL Continue statement and return the following statement as output (In Our case 1, 2, 4, 5, 6, 8, 9, 10). You can also try SQL ELSE IF for more conditions.

PRINT 'Tutorial Gateway Views = ' + CONVERT(VARCHAR, @Val)

If this condition is True, the SQL Continue statement will execute. Next, the While loop iteration will stop at that number (i.e., 3 and 7) without printing the other statements. For better understanding, we placed the below SQL Server statement inside the If block. So, whenever the iteration break, that value will be printed from this statement.

PRINT 'Skipped By Continue Statement = ' + CONVERT(VARCHAR, @Val)

The following statement is outside the While Loop, and it has nothing to do with the expression in the While loop. It means, irrespective of condition result, this statement will execute.

PRINT 'This statement is Coming from Outside the While Loop'
