Question

I need to find a select statement that will return either a record that matches my input exactly, or the closest match if an exact match is not found.

Here is my select statement so far.

SELECT * FROM [myTable]  WHERE Name = 'Test' AND Size = 2 AND PType = 'p'  ORDER BY Area DESC 

What I need to do is find the closest match to the ‘Area’ field, so if my input is 1.125 and the database contains 2, 1.5, 1 and .5 the query will return the record containing 1.

My SQL skills are very limited so any help would be appreciated.

Answer 1

get the difference between the area and your input, take absolute value so always positive, then order ascending and take the first one

SELECT TOP 1 * FROM [myTable]  WHERE Name = 'Test' and Size = 2 and PType = 'p' ORDER BY ABS( Area - @input )
