How to compare two strings in SQL :

  2. STRCMP() returns 0 if the strings are the same, -1 if the first argument is smaller than the second according to the current sort order, and NULL if either argument is NULL . It returns 1 otherwise.
  3. STRCMP() performs the comparison using the collation of the arguments.
