  Hi

  I have below parameters .

  @frDate date,

  @toDate date,

  @VName nvarchar(100) = null,

  @CName nvarchar(100) = null,

  I want if user has entered nothing in VName and Cname then

  where should be between @frDate and @ Todate

  If user has entered Vname & Dates then

  all records with date range and Vname = @ Vname and all CName records like so on

  Thanks

  IF <test>

  BEGIN

  SELECT... FROM...WHERE... <params>

  END

  ELSE

  SELECT...FROM WHERE <different params>

  There's nothing stopping you from forking the two queries with an IF statement.

  It's beginning to look a lot like ... a catch-all query.

  I suggest you get yourself a nice drink and read this article: https://sqlinthewild.co.za/index.php/2018/03/13/revisiting-catch-all-queries/
