In this programming language, you do not have a loop sentence like in C++, C#, and Java. You use the WHILE Sentence instead. The following example will create a table named myIDs and insert 10 values using a WHILE sentence: 1 2 3 4 5 6 7 8 9 10 11 CREATE TABLE myIDs( id...
Can we do MAX inside nested CASE Statement? Can we generate pipe delimited column through SQL query Can we optimise While Loop in sql server for large number of data? Can we pass parameters to the trigger?(Beginner) Can we RAISERROR inside MERGE Statement Can we select Bottom 1000 rows of...
While T-SQL may be an unlikely method of solving this problem, the solutions below highlight the power of SQL Server through the creative solutions of the authors. As with any good interview question, the initial phrasing of the question does not provide all of the necessary r...

Sometimes there is a need to execute the same command or set of commands over and over again. This may be to insert or update test data or it may be to put a load on your server for performance testing. One way to do this is to setup a while loop and execute the code over and ...

The WHILE loop will iterate once per character in the current string that is being examined. The@Current_Characterpulls one character at a time as we run through this loop. We then proceed to determine the ASCII value of the character, also storing that in a scalar variable(@Current_Characte...
A table scan was taking place on a table while executing the query even though the table has a proper indexing implementation. The table scan was taking 30% of the overall query execution time. A "nested loop join" (one of three kinds of joining implementation) was occurring for selecting ...
