对SqlDouble 的两个实例进行比较,以确定第一个实例是否大于第二个实例。 C# 复制 public static System.Data.SqlTypes.SqlBoolean GreaterThan (System.Data.SqlTypes.SqlDouble x, System.Data.SqlTypes.SqlDouble y); 参数 x SqlDouble SqlDouble 结构。 y SqlDouble SqlDouble 结构。 返回 SqlBoolean...
比较SQL Server 中的两个表达式(比较运算符)。 当比较非空表达式时,如果左操作数的值大于右操作数,则结果为 TRUE;否则结果为 FALSE。 如果任何一个操作数为 NULL 或两个都为 NULL,则请参阅主题SET ANSI_NULLS (Transact-SQL)。 Transact-SQL 语法约定 ...
FOR SOME %ELEMENT 是一个集合谓词。 该谓词与OR逻辑操作符的使用受到限制,如下所示。 不能使用OR逻辑操作符将引用表字段的集合谓词与引用另一个表中的字段的谓词关联起来。 例如, 代码语言:javascript 代码运行次数:0 运行 AI代码解释 WHERE FOR SOME %ELEMENT(t1.FavoriteColors) (%VALUE='purple') OR t2....
err.println(plainSelectNot);// SELECT * FROM test WHERE test.user_id <> '123456' // 其他运算符, 参考上面代码添加表达式即可 GreaterThan gt = new GreaterThan(); // ">" GreaterThanEquals geq = new GreaterThanEquals(); // ">=" MinorThan mt = new MinorThan(); // "<" MinorThan...
Compares two expressions for greater than or equal (a comparison operator). When you compare nonnull expressions, the result is TRUE if the left operand has a greater or equal value than the right operand; otherwise, the result is FALSE....

The selectivity is of no use here, but one column order is still better than the other. To optimize performance, it is very important to know the scanned index range. With most databases you can even see this in the execution plan—you just have to know what to look fo...
The stop time passed to the rollforward utility must be greater than or equal to the time the backup ended on the specified nodes. If ",..." is displayed at the end of the node list, see the administration notification log for the complete list of nodes. ...
