Loops in SQL Server Example: WHILE Loop. DECLARE @i INT = 10; WHILE @i <= 30 BEGIN PRINT (@i); SET @i = @i + 10; END; Example: WHILE with BREAK. DECLARE @i INT = 10; WHILE @i <= 30 BEGIN PRINT (@i); SET @i = @i + 10; IF @i = 30 BREAK; END; Example: WHILE with CONTINUE. ... Example: Nested Loop.

Then we will iterate through these array values using a WHILE clause, we have used two variables to loop through the array – INDEXVAR and TOTALCOUNT. As usual, the loop will continue until INDEXVAR is smaller than TOTALCOUNT. Using INDEXVAR and WHERE clause, we will get current array index value.

The control structure used for loops in SQL is the WHILE loop. The WHILE loop in SQL checks a specific condition and executes the block of code until the condition is false. The code block inside the WHILE loop contains the operations that need to be performed on each row of the data set.

Let's assume you want to loop through a table variable having the structure like below. To iterate through this table, just add one more column ( Processed ) in this table variable.

You must use a CURSOR in a stored proc. The CURSOR allows row by row access. The loop is controlled by a DO WHILE statement. You could see an example in the SQL HELP.

Here is the SQL statement: CREATE TABLE CursorTest ( CursorTestID INT IDENTITY(1,1) PRIMARY KEY CLUSTERED, Filler VARCHAR(4000), RunningTotal BIGINT ) GO. INSERT INTO dbo. ... CREATE TABLE #TallyTable ( Iterator INT IDENTITY(1, 1), ProductID INT ); INSERT INTO #TallyTable ( ProductID ) SELECT ProductID FROM dbo.

A SQL SELECT statement has a set of rows to loop through. The database server creates an open cursor (often called a cursor object or cursor variable) on the SELECT. The client program may FETCH FROM … this open cursor within a looping statement.

To select rows using selection symbols for character or graphic data, use the LIKE keyword in a WHERE clause, and the underscore and percent sign as selection symbols. You can create multiple row conditions, and use the AND, OR, or IN keywords to connect the conditions.
