SQL子句granted by current role

As an AI language model, I don't have any current role assigned to me. However, the SQL clause "GRANTED BY CURRENT ROLE" refers to the permissions granted to the current role that is executing a particular SQL statement. This clause is used in conjunction with the "REVOKE" statement to revoke the privileges granted to the current role. It is also used to check the permissions of the current role before executing a particular SQL statement.

sql server中compute by子句

在SQL Server中，COMPUTE BY子句用于在GROUP BY子句的基础上计算聚合函数。它可以按照一个或多个列对结果进行分组，并计算每个分组的聚合函数值。COMPUTE BY子句可以用于SELECT语句和UNION语句中。它的语法如下：

SELECT column1, column2, ..., aggregate_function(column_name)
FROM table_name
GROUP BY column1, column2, ...
COMPUTE aggregate_function(column_name) BY column_name1, column_name2, ...

其中，aggregate_function是聚合函数，column_name是要计算的列名，table_name是要查询的表名，column1、column2等是要分组的列名，column_name1、column_name2等是要按照其计算聚合函数的列名。

SQL中,ORDER BY子句的位置是

在 SQL 语句中，ORDER BY 子句应该出现在 SELECT 语句的末尾，以便按照指定的列对结果进行排序。例如：

SELECT column1, column2, column3
FROM table_name
WHERE condition
ORDER BY column1 ASC, column2 DESC;

在这个例子中，ORDER BY 子句出现在 WHERE 子句后面，用于按照 column1 升序和 column2 降序对结果进行排序。
