如何使用扩展事件来跟踪存储过程中使用的表 运行

How to use extended events to track tables used in stored procedures being run

如何使用扩展事件 (SQL Server 2012) 告诉我何时在存储过程中使用了某些表。我想删除一些表,所以我想知道使用这些表的存储过程是否实际上是 运行。

代码示例设置了支持对象。并创建一个我希望工作但没有工作的会话。当您 运行 那些存储过程(ListEmpListProd)时,我希望它们被拾取,因为它们包含我正在跟踪的表(EmployeesProducts) .

请注意,我还尝试使用 sp_statement_starting 事件:

-- setup supporting objects
CREATE TABLE Employees (Col1 VARCHAR(10));
CREATE TABLE Products (Col1 VARCHAR(10));
GO

INSERT INTO Employees(Col1) VALUES ('Bob');
INSERT INTO Products(Col1) VALUES ('Bolts');
GO

CREATE PROCEDURE ListEmp 
AS 
    SELECT * FROM Employees;
GO

CREATE PROCEDURE ListProd 
AS 
    SELECT * FROM Products;
GO

-- create extended event (that is not doing what I want)
CREATE EVENT SESSION XE_TrackEmployeesAndProductsTables
ON SERVER
ADD EVENT sqlserver.sp_statement_completed
(
    SET collect_statement=1
    ACTION
        (
            sqlserver.database_name,
            sqlserver.sql_text
        )
    WHERE
        (
            sqlserver.like_i_sql_unicode_string(sqlserver.sql_text,N'%Employees%')
            OR sqlserver.like_i_sql_unicode_string(sqlserver.sql_text,N'%Products%')
        )
);
ALTER EVENT SESSION XE_TrackEmployeesAndProductsTables ON SERVER STATE=START;
GO

-- run procs that I want to be picked up by my session (but aren't)
EXEC ListEmp; 
EXEC ListProd;


-- cleanup
DROP EVENT SESSION XE_TrackEmployeesAndProductsTables ON SERVER;
DROP PROC ListEmp;
DROP PROC ListProd;
DROP TABLE Employees;
DROP TABLE Products;

我会将其添加到您要跟踪的任何存储过程的开头:

declare @msg nvarchar(128) = concat('Stored proc ',OBJECT_NAME(@@PROCID),' run.')
EXEC master..sp_trace_generateevent  @event_class = 82, @userinfo = @msg;  

您可以使用像这样的 XEvent 会话来跟踪:

CREATE EVENT SESSION [UserEvent] ON SERVER 
ADD EVENT sqlserver.user_event
ADD TARGET package0.event_file(SET filename=N'UserEvent')

您可以像这样识别在静态 SQL 中引用 table 的所有过程:

select distinct object_name(d.object_id) referencing_object, SCHEMA_NAME(o.schema_id) referencing_object_schema
from sys.sql_dependencies d
join sys.objects o
  on o.object_id = d.object_id
where d.referenced_major_id = object_id('Sales.SalesOrderHeader')
  and o.type = 'P'
