Assume that I have the following simple query 

  select the top 1 name for months < / Code>

which gives name = "march" is it possible to change this result? Instead of "march" let me name = "3" what SQL is able to do such things? I am using an MSSQL database.

[Update] Corrected the query. When writing this simple example, I mixed it with MySQL [/ Update]
