The following forms of the comparison operators are also supported in basic and quantified predicates in coded pages where the exclamation point is X'5A': !=, !<, and !> . In addition, in code pages 437, 819, and 850, the forms ¬=, ¬<, and ¬> are supported. All these product-specific forms of the comparison operators are intended only to support existing SQL statements that use these operators and are not recommended for use when writing new SQL statements.
