Now, let us convert the above example toWHILE loop. To convert a cursor to while loop, first you have to find the total number of rows in the table. Then you have to iterate through the table rows using WHILE control-of-flow element till the total row count is reached. Here is how ...
In this example, we’re creating the temporary table#TempStudentand populating it with data from theStudenttable. Then, we use a WHILE loop to iterate through each row while using ORDER BY with OFFSET and FETCH to retrieve the row based on thecounter. 5.2. Using Temporary Tables in MySQL ...

MAXRECURSIONcan be used to prevent a poorly formed recursive common table expression from entering into an infinite loop. The following example intentionally creates an infinite loop and uses theMAXRECURSIONhint to limit the number of recursion levels to two. The example uses theAdventureWorks2022databa...

The WHILE loop, according toSQL Server Loop through Table Rows without Cursorarticle, states that a WHILE is faster than a cursor and uses less locks and use less TEMPDB resources. However, WHILE loops are still slow and have a performance impact. If it is a nested loop, it will be even...
