Here's an example query using the "Not Equals To" operator: SELECT product_name, price FROM products WHERE price <> 10.99; In this query, we're retrieving the product names and prices of products whose price is
So it is recommended to use <> for NOT EQUAL Operator. 在本文中,我们将探讨SQL 中的 NOT 运算符并附有适当的示例和简短的解释。 SQL NOT EQUAL 语法 SELECT * FROM table_name WHERE column_name != value; 演示SQL 数据库 在本关于 NOT EQUAL 运算符的教程中,我们将使用下表作为示例,并查看 SQL ...
Tests whether one expression is not equal to another expression (a comparison operator). If either or both operands are NULL, NULL is returned. Functions the same as the<> (Not Equal To)comparison operator. See Also Expressions (Transact-SQL) ...
When you compare nonnull expressions, the result is TRUE if the left operand is not equal to the right operand; otherwise, the result is FALSE. If either or both operands are NULL, see the topic SET ANSI_NULLS (Transact-SQL). Transact-SQL syntax conventions Syntax syntaxsql Copy ...
Tests whether one expression is not equal to another expression (a comparison operator). If either or both operands are NULL, NULL is returned. Functions the same as the <> (Not Equal To) comparison operator. See Also Reference Expressions (Transact-SQL) Operators (Transact-SQL) Concepts ...
Tests whether one expression is not equal to another expression (a comparison operator). Syntax Not_Equal_To:= expression != expression. 備註 U-SQL uses C# null semantics which is 2-valued and not 3-valued as in ANSI SQL. Remarks expression Is any valid expression. If the expressions are...

注意:因between 的范围是个闭区间(greater than or equal to low value and less than or equal to high value .), 故严格意义上应该再减去一个趋于0的小数,这里暂且设置成减去1秒(1/(24*60*60)),如果不要求这么精确的话,可以略掉这步。 七、对where语句的法则 ...
