!> (Not Greater Than) (Transact-SQL)
Applies to: 
SQL Server
Azure SQL Database
Azure SQL Managed Instance
Compares two expressions (a comparison operator). When you compare non-null expressions, the result is TRUE if the left operand doesn't have a greater value than the right operand. Otherwise, the result is FALSE. Unlike the = (equality) comparison operator, the result of the !> comparison of two NULL values doesn't depend on the ANSI_NULLS setting.
