Sql server 获取集合统计信息的当前值[XML | TIME | IO]

使用T-SQL，如何检索可以使用这些命令设置的当前配置值

SET STATISTICS TIME ON
SET STATISTICS XML ON
SET STATISTICS IO ON

我查看了

@@OPTIONS

，但没有提到它们。任何其他魔法变量或系统表？

将作为结果集返回设置：

DBCC USEROPTIONS;

样本结果：

+-------------------------+----------------+
|       Set Option        |     Value      |
+-------------------------+----------------+
| textsize                | 2147483647     |
| language                | us_english     |
| dateformat              | mdy            |
| datefirst               | 7              |
| statistics time         | SET            |
| statistics io           | SET            |
| statistics XML          | SET            |
| lock_timeout            | -1             |
| quoted_identifier       | SET            |
| arithabort              | SET            |
| ansi_null_dflt_on       | SET            |
| ansi_warnings           | SET            |
| ansi_padding            | SET            |
| ansi_nulls              | SET            |
| concat_null_yields_null | SET            |
| isolation level         | read committed |
+-------------------------+----------------+

可以将结果插入临时表或变量中，以进行其他查询/筛选。此示例包括感兴趣的选项，并执行左连接以包括可能未设置的选项：

DECLARE @results TABLE(
     SetOption sysname
    ,Value nvarchar(46)
);
INSERT INTO @results(SetOption, Value)
    EXEC(N'DBCC USEROPTIONS;');
SELECT
      so.SetOption 
    , COALESCE (Value, N'NOT SET') AS Value
FROM (VALUES
     (N'statistics time')
    ,(N'statistics xml')
    ,(N'statistics io')
) AS so(SetOption)
LEFT JOIN @results AS r ON r.SetOption = so.SetOption;

SET STATISTICS TIME OFF;
SET STATISTICS XML OFF;
SET STATISTICS IO ON;
DECLARE @results TABLE(
     SetOption sysname
    ,Value nvarchar(46)
);
INSERT INTO @results(SetOption, Value)
    EXEC(N'DBCC USEROPTIONS;');
SELECT
      so.SetOption 
    , COALESCE (Value, N'NOT SET') AS Value
FROM (VALUES
     (N'statistics time')
    ,(N'statistics xml')
    ,(N'statistics io')
) AS so(SetOption)
LEFT JOIN @results AS r ON r.SetOption = so.SetOption;

结果:

+-----------------+---------+
|    SetOption    |  Value  |
+-----------------+---------+
| statistics time | NOT SET |
| statistics xml  | NOT SET |
| statistics io   | SET     |
+-----------------+---------+

太棒了，谢谢。如果其他人试图在其存储过程中处理输出，请参见@Hannobo，我添加了一个示例来扩展该技术。
