Question

What is the syntax of a for loop in TSQL?

Answer 1

Extra Info

Just to add as no-one has posted an answer that includes how to actually iterate though a dataset inside a loop, you can use the keywords OFFSET FETCH.

Usage

DECLARE @i INT = 0;
SELECT @count=  Count(*) FROM {TABLE}

WHILE @i <= @count
BEGIN

    SELECT * FROM {TABLE}
    ORDER BY {COLUMN}
    OFFSET @i ROWS   
    FETCH NEXT 1 ROWS ONLY  

    SET @i = @i + 1;

END
