IF ELSE Statement in SQL

Question

SELECT S.Id, S.Name, S.Version, S.SoftNo
FROM SOFTWARE S WITH(NOLOCK)
WHERE (IF S.Version = 0 THEN S.Version > 0 ELSE S.Version = @Version)
AND (IF S.SoftNo = 0 THEN          


        

Answer 1

Instead, I came up with this workaround,

sSQL = @"SELECT S.Id, S.Name, S.Version, S.SoftNo
         FROM SOFTWARE S WITH(NOLOCK)
         WHERE 1 = 1";
// 1=1 is used just to list everything.

if(pVersion != 0)
{
     sSQL += " AND S.Version = @Version";
}
if(pSoftNo != 0)
{
     sSQL += " AND S.SoftNo = @SoftNo";
}

Conclusion, if else part is moved to code side.
