如何将存储过程 (sp_whoisactive) 的结果插入 SQL 托管实例中的表中

Question

我们的 Azure SQL 托管实例数据库存在问题，正在尝试收集一些统计信息以帮助我们解决问题。因此，我创建了一个名为 [dbo].[WhoIsActive] 的表，其架构如下：

CREATE TABLE [dbo].[WhoIsActive](
    [dd hh:mm:ss.mss] [varchar](8000) NULL,
    [session_id] [smallint] NOT NULL,
    [sql_text] [xml] NULL,
    [login_name] [nvarchar](128) NOT NULL,
    [wait_info] [nvarchar](4000) NULL,
    [CPU] [varchar](30) NULL,
    --[tran_log_writes] [nvarchar](4000) NULL,
    [tempdb_allocations] [varchar](30) NULL,
    [tempdb_current] [varchar](30) NULL,
    [blocking_session_id] [smallint] NULL,
    [reads] [varchar](30) NULL,
    [writes] [varchar](30) NULL,
    [physical_reads] [varchar](30) NULL,
    [used_memory] [varchar](30) NULL,
    --[query_plan] [xml] NULL,
    [status] [varchar](30) NOT NULL,
    --[tran_start_time] [datetime] NULL,
    [open_tran_count] [varchar](30) NULL,
    [percent_complete] [varchar](30) NULL,
    [host_name] [nvarchar](128) NULL,
    [database_name] [nvarchar](128) NULL,
    [program_name] [nvarchar](128) NULL,
    [start_time] [datetime] NOT NULL,
    [login_time] [datetime] NULL,
    [request_id] [int] NULL,
    [collection_time] [datetime] NOT NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO

/****** Object:  Index [cx_collection_time]    Script Date: 2/28/2023 7:17:59 AM ******/
CREATE CLUSTERED INDEX [cx_collection_time] ON [dbo].[WhoIsActive]
(
    [collection_time] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, OPTIMIZE_FOR_SEQUENTIAL_KEY = OFF) ON [PRIMARY]
GO

然后我从https://github.com/amachanic/sp_whoisactive/releases

创建了一个广为人知的存储过程sp_whoisactive最新版本

下一步是定期将过程的结果插入表中。

选项1： 我尝试过这样做：

Insert Into [dbo].[WhoIsActive]
 Exec sp_whoisactive 

但出现此错误：

消息 8164，级别 16，状态 1，过程 sp_whoisactive，第 3737 行 [批量开始行 44]
INSERT EXEC 语句不能嵌套。*

选项2：我尝试过以下方法：

SET NOCOUNT ON;

DECLARE @retention INT = 60,
        @destination_table VARCHAR(500) = 'WhoIsActive',
        @destination_database sysname = 'DBATools',
        @schema VARCHAR(MAX),
        @SQL NVARCHAR(4000),
        @parameters NVARCHAR(500),
        @exists BIT;

SET @destination_table = @destination_database + '.dbo.' + @destination_table;

--create the logging table
IF OBJECT_ID(@destination_table) IS NULL
    BEGIN;
        EXEC dbo.sp_WhoIsActive @get_transaction_info = 1,
                                @get_outer_command = 1,
                                @get_plans = 1,
                                @return_schema = 1,
                                @schema = @schema OUTPUT;
        SET @schema = REPLACE(@schema, '<table_name>', @destination_table);
        EXEC ( @schema );
    END;

--create index on collection_time
SET @SQL
    = 'USE ' + QUOTENAME(@destination_database)
      + '; IF NOT EXISTS (SELECT * FROM sys.indexes WHERE object_id = OBJECT_ID(@destination_table) AND name = N''cx_collection_time'') SET @exists = 0';
SET @parameters = N'@destination_table varchar(500), @exists bit OUTPUT';
EXEC sys.sp_executesql @SQL, @parameters, @destination_table = @destination_table, @exists = @exists OUTPUT;

IF @exists = 0
    BEGIN;
        SET @SQL = 'CREATE CLUSTERED INDEX cx_collection_time ON ' + @destination_table + '(collection_time ASC)';
        EXEC ( @SQL );
    END;

--collect activity into logging table
EXEC dbo.sp_WhoIsActive @get_transaction_info = 1,
                        @get_outer_command = 1,
                        @get_plans = 1,
                        --@destination_table = [WhoIsActive];
                        @destination_table = @destination_table;



--purge older data
SET @SQL
    = 'DELETE FROM ' + @destination_table + ' WHERE collection_time < DATEADD(day, -' + CAST(@retention AS VARCHAR(10))
      + ', GETDATE());';
EXEC ( @SQL );

我现在收到此错误消息：

消息 213，第 16 级，状态 1，第 1 行
列名称或提供的值的数量与表定义不匹配。

所以我的问题是，将这些数据存储到表中的最佳方法是什么？还是我哪里做错了？

你只需要添加以下参数并执行，它就会创建一个“CREATE Table”语句：在顶部添加：DECLARE @Schema VARCHAR(MAX); EXEC sp_whoisactive... 在此过程中使用您喜欢的任何格式，但最后添加以下变量： @return_schema = 1, @SCHEMA = @schema 输出 打印@Schema

然后当你执行它来记录到你的表时，添加这个参数： @destination_table = '.dbo.
