What is the diference between the following two statements? Which one is better? option 1 or option 2?

  1. WHERE IFNULL(T1.”U_CNote”, ‘ ‘) = ‘ ‘ and T0.”DocEntry” = :list_of_cols_val_tab_del and …
  2. WHERE T1.”U_CNote” IS NULL and T0.”DocEntry” = :list_of_cols_val_tab_del and …

Option 1 is safer because it checks for white spaces i.e. if a user types the space key instead of a letter, in Option 1 SQL will still read this as a null but in Option 2, SQL willl not see this as a null, yet in essence it is.
