T-SQL 1=1 Performance Hit

Question

For my SQL queries, I usually do the following for SELECT statements:

SELECT ...
FROM table t
WHERE 1=1
  AND t.[column1] = @param1
  AND t.[column2] = @para         


        

Answer 1

It is likely that if you use the profiler and look, you will end up seeing that the optimizer will end up ignoring that more often than not, so in the grand scheme of things, there probably won't be much in the way of performance gain or losses.
