“谁把我的表给删拉”，”谁删了整个表阿”…碰到这种棘手的情况，你如果没有预先做好准备，真的是头都要急炸了。那怎么能抓出这个”凶手”呢？SQL Trace, SQL Profile，SQL Trigger，Extended Events等着伺候你呢，更别说CLR，Service Broker等重量级武器了
“谁把我的表给删拉”，”谁删了整个表阿”…碰到这种棘手的情况，你如果没有预先做好准备，真的是头都要急炸了。那怎么能抓出这个”凶手”呢？SQL Trace, SQL Profile，SQL Trigger，Extended Events等着伺候你呢，更别说CLR，Service Broker等重量级武器了，别急！
工具虽好，但是也得用得贴合场景才能发挥作用，要不然跟你的SQL Server抢IO，那就得不偿失了。比如高频的OLTP场合，你还用TRIGGER把大量的DML语句都写到当前数据库去，那不是给数据库增加一倍工作量么。当然控制好权限，做好测试也能保证你的数据安全。这不妨碍我们讨论auditing SQL。
SQL Profiler是基于SQL Trace的，而SQL Trace是会被更高版本的SQL Server给逐渐摒弃的，所以我们就只讨论一个就可以了。一开始我知道 SQL Profiler是可以可视化监控即时的SQL Server活动的，但是缺点是不能保存或者自动执行，需要人工干预。经过研究，它是可以自动保存截取结果的。
让我们认识下“源”：想要抓“破坏分子”，首先要知道“破环分子”的标示有哪些，漏抓，错抓，都是失手的表现。访问SQL SERVER的方式有很多种，有ADO.NET, JDBC, SQL SERVER Management Studio, ODBC等各种方法，也有 Ad-hoc SQL, Stored Procedure等表现形式，是否每一种的方式都有各自不同的格式呢？最好的方法就是针对每种方式都来做个例子验证下。
首先最简单的SSMS方式，我们将SQL Profiler限制到某一个数据库，lenistest4。 在SSMS里面输入：
<code class=" hljs rust"><span class="hljs-keyword">use</span> lenistest4 go</code>
SQL Profiler显示的是SQL:BatchCompleted。
这里与有没有go无关。当你选中一块SQL区域并执行，其中如果有go那就有关系了，比如：
<code class=" hljs sql"><span class="hljs-operator"><span class="hljs-keyword">select</span> top <span class="hljs-number">10</span> * <span class="hljs-keyword">from</span> sys.tables <span class="hljs-keyword">go</span> <span class="hljs-keyword">select</span> top <span class="hljs-number">10</span> * <span class="hljs-keyword">from</span> dbo.region <span class="hljs-keyword">go</span></span></code>
这里一个go分割了一个batch。最后一个go没有意义，我们提交了一段代码，这段代码相当于是一个大batch，如果中间有go，那这个go 就代表了一个子batch。
那么用动态语句，会有什么Trace格式呢：
<code class=" hljs css"><span class="hljs-tag">declare</span> <span class="hljs-at_rule">@<span class="hljs-keyword">sqlstatement</span> <span class="hljs-function">nvarchar(max)</span> = N<span class="hljs-string">'select top 10 * from dbo.region'</span> </span>; <span class="hljs-tag">exec</span> <span class="hljs-tag">sp_executesql</span> <span class="hljs-at_rule">@<span class="hljs-keyword">sqlstatement</span></span></code>
这里有SQL:Batch*, SQL:Stmt*,SP:Stmt， SQL:Stmt*代表的是一系列的SQL命令，比如declare, set等；SP:Stmt*代表了stored procedure的范围内语句。
<code class=" hljs vbnet"><span class="hljs-keyword">declare</span> @sqlstatement nvarchar(max) = N<span class="hljs-comment">'</span> <span class="hljs-keyword">declare</span> @regionName varchar(<span class="hljs-number">20</span>) = <span class="hljs-comment">''China''</span> <span class="hljs-keyword">select</span> top <span class="hljs-number">10</span> * <span class="hljs-keyword">from</span> dbo.region <span class="hljs-keyword">where</span> regionName = @regionName<span class="hljs-comment">' ;</span> exec sp_executesql @sqlstatement</code>
上面这段SQL，验证了SQL命令select和declare是不是都被看作是SP:Stmt* ? 其实在一个batch里面，SQL命令里面DML语句也是被当作Statement来处理的。
如果在动态SQL里面有go是不是也会有SP:Batch*? 我们接着往下看：
<code class=" hljs vbnet"><span class="hljs-keyword">declare</span> @sqlstatement nvarchar(max) = N<span class="hljs-comment">'</span> <span class="hljs-keyword">declare</span> @regionName varchar(<span class="hljs-number">20</span>) = <span class="hljs-comment">''China''</span> <span class="hljs-keyword">select</span> top <span class="hljs-number">10</span> * <span class="hljs-keyword">from</span> dbo.region <span class="hljs-keyword">where</span> regionName = @regionName; go <span class="hljs-keyword">declare</span> @regionName2 varchar(<span class="hljs-number">20</span>) = <span class="hljs-comment">''England''</span> <span class="hljs-keyword">select</span> top <span class="hljs-number">10</span> * <span class="hljs-keyword">from</span> dbo.region <span class="hljs-keyword">where</span> regionName = @regionName2 <span class="hljs-comment">' ;</span> exec sp_executesql @sqlstatement</code>
Msg 102, Level 15, State 1, Line 12
Incorrect syntax near ‘go’.
可以看到go是不能用在动态语句里面的。
为了验证SP:Stmt*是不是指的是存储过程里面的语句，我们先创建一个stored procedure,然后再执行它：
<code class=" hljs sql"><span class="hljs-operator"><span class="hljs-keyword">create</span> <span class="hljs-keyword">procedure</span> dbo.getRegionName <span class="hljs-keyword">as</span> <span class="hljs-keyword">begin</span> <span class="hljs-keyword">declare</span> @regionName <span class="hljs-keyword">varchar</span>(<span class="hljs-number">20</span>) = <span class="hljs-string">'China'</span> <span class="hljs-keyword">select</span> top <span class="hljs-number">10</span> * <span class="hljs-keyword">from</span> dbo.region <span class="hljs-keyword">where</span> regionName = @regionName <span class="hljs-keyword">declare</span> @regionNamex <span class="hljs-keyword">varchar</span>(<span class="hljs-number">20</span>) = <span class="hljs-string">'England'</span> <span class="hljs-keyword">select</span> top <span class="hljs-number">10</span> * <span class="hljs-keyword">from</span> dbo.region <span class="hljs-keyword">where</span> regionName = @regionNamex <span class="hljs-keyword">end</span> <span class="hljs-keyword">exec</span> dbo.getRegionName</span></code>
正是如此 ！综上所述， SQL:Batch* ， 这里的batch相当于是个scope，一个大的执行空间，里面的所有 SQL 语句都是statement，包括DML，DDL等一系列 T-SQL语句 ；而SP:Stmt*又是存储过程的执行空间，里面所有的 T-SQL语句都是statement。
下面看段c#调用这个stored procedure，看看trace是如何识别的：
<code class=" hljs vala"><span class="hljs-keyword">using</span> System;
<span class="hljs-keyword">using</span> System.Collections.Generic;
<span class="hljs-keyword">using</span> System.Linq;
<span class="hljs-keyword">using</span> System.Text;
<span class="hljs-keyword">using</span> System.Threading.Tasks;
<span class="hljs-keyword">using</span> System.Data.SqlClient;
<span class="hljs-keyword">using</span> System.Data.SqlTypes;
<span class="hljs-keyword">using</span> System.Data;
<span class="hljs-class"><span class="hljs-keyword">namespace</span> <span class="hljs-title">AccessLenistest4DB</span>
{</span>
<span class="hljs-class"><span class="hljs-keyword">class</span> <span class="hljs-title">Program</span>
{</span>
<span class="hljs-keyword">static</span> <span class="hljs-keyword">void</span> Main(<span class="hljs-keyword">string</span>[] args)
{
SqlConnection<span class="hljs-constant"> ICONN </span>= <span class="hljs-keyword">new</span> SqlConnection(@<span class="hljs-string">"data source = (localhost);initial catalog = lenistest4 ;user id = sa; password = sas;"</span>);
SqlCommand icmd = <span class="hljs-keyword">new</span> SqlCommand();
icmd.Connection = ICONN;
icmd.CommandType = System.Data.CommandType.StoredProcedure;
icmd.CommandText = <span class="hljs-string">"dbo.getRegionName"</span>;
SqlDataAdapter ida = <span class="hljs-keyword">new</span> SqlDataAdapter(icmd);
DataSet localds = <span class="hljs-keyword">new</span> DataSet();
<span class="hljs-keyword">try</span>
{
ICONN.Open();
ida.Fill(localds);
}
<span class="hljs-keyword">catch</span>(SqlException se)
{
Console.Write(se.ToString());
}
}
}
}</code>
这儿多了个RPC， remote procedure call。其他都一样，所以RPC可以看作是一种命名空间，用阿里区别访问协议。这里要区别的是我们调用的是stored procedure，所以会RPC。所以如果我们是用纯SQL来访问数据库，那会不会有 RPC标示呢：
<code class=" hljs vala"><span class="hljs-keyword">using</span> System;
<span class="hljs-keyword">using</span> System.Collections.Generic;
<span class="hljs-keyword">using</span> System.Linq;
<span class="hljs-keyword">using</span> System.Text;
<span class="hljs-keyword">using</span> System.Threading.Tasks;
<span class="hljs-keyword">using</span> System.Data.SqlClient;
<span class="hljs-keyword">using</span> System.Data.SqlTypes;
<span class="hljs-keyword">using</span> System.Data;
<span class="hljs-class"><span class="hljs-keyword">namespace</span> <span class="hljs-title">AccessLenistest4DB</span>
{</span>
<span class="hljs-class"><span class="hljs-keyword">class</span> <span class="hljs-title">Program</span>
{</span>
<span class="hljs-keyword">static</span> <span class="hljs-keyword">void</span> Main(<span class="hljs-keyword">string</span>[] args)
{
SqlConnection<span class="hljs-constant"> ICONN </span>= <span class="hljs-keyword">new</span> SqlConnection(@<span class="hljs-string">"data source = (localhost);initial catalog = lenistest4 ;user id = sa; password = sas;"</span>);
SqlCommand icmd = <span class="hljs-keyword">new</span> SqlCommand();
icmd.Connection = ICONN;
icmd.CommandType = System.Data.CommandType.Text;
icmd.CommandText = <span class="hljs-string">"select * from dbo.region"</span>;
SqlDataAdapter ida = <span class="hljs-keyword">new</span> SqlDataAdapter(icmd);
DataSet localds = <span class="hljs-keyword">new</span> DataSet();
<span class="hljs-keyword">try</span>
{
ICONN.Open();
ida.Fill(localds);
}
<span class="hljs-keyword">catch</span>(SqlException se)
{
Console.Write(se.ToString());
}
}
}
}</code>
并没有RPC。 事实证明 RPC只出现在客户端语言调用存储过程的例子。
Trace的手段 ：“破坏分子”的特征被识别了，接下来就是怎么去抓捕的手段问题了。可以有即时的GUI工具，比如SQL Profiler，Extended Event(SSMS自带)，也可以用脚本去抓，并放在特定存储里面供稍后分析使用。
SQL Profiler 是即时的GUI工具很好用，可以保存结果，也可以自定义模板，缺点在于你必须开一个额外的窗口去跟踪，有时候数据量太大，还会影响传输，对多太SQL Server做监控就不怎么容易了，一个一个手工去开窗口，是不是很麻烦 ?
这里有Extended Events可以帮我们用脚本的形式去捕捉这些T-SQL语句，这里有个简单的例子：
1.1 Extended Events 概念：由一系列自动触发的 event 产生性能数据，经过 event engine 的收集，存放到指定的输出文件，以供后续的分析。
1.2 XE 涉及到的动态管理试图 : sys.dm_xe_packages; sys.dm_xe_objects;sys.dm_xe_sessions
1.3 基本用法:
2.3.1 创建一个 Event Session
<code class=" hljs sql"><span class="hljs-operator"><span class="hljs-keyword">create</span> event <span class="hljs-keyword">session</span> capture_sql_events <span class="hljs-keyword">on</span> server <span class="hljs-keyword">add</span> event sqlserver.sql_statement_completed ( <span class="hljs-keyword">action</span>(sqlserver.sql_text) ) <span class="hljs-keyword">add</span> target package0.event_file ( <span class="hljs-keyword">set</span> filename = <span class="hljs-string">'E:\data_bu\capture_sql_events.xel'</span>, metadatafile = <span class="hljs-string">'E:\data_bu\capture_sql_event.xem'</span> ) <span class="hljs-keyword">go</span></span></code>
2.3.2 启用这个 Event session 来收集数据
<code class=" hljs sql"><span class="hljs-operator"><span class="hljs-keyword">alter</span> event <span class="hljs-keyword">session</span> capture_sql_events <span class="hljs-keyword">on</span> server STATE = <span class="hljs-keyword">start</span> <span class="hljs-keyword">go</span></span></code>
2.3.3 停用这个 Event session
<code class=" hljs sql"><span class="hljs-operator"><span class="hljs-keyword">alter</span> event <span class="hljs-keyword">session</span> capture_sql_events <span class="hljs-keyword">on</span> server state = stop <span class="hljs-keyword">go</span></span></code>
2.3.4 修改一个 session 来增加或者删除对 Event 的监控
<code class=" hljs sql"><span class="hljs-operator"><span class="hljs-keyword">alter</span> event <span class="hljs-keyword">session</span> capture_sql_events <span class="hljs-keyword">on</span> server <span class="hljs-keyword">add</span> event sqlserver.sql_batch_completed (<span class="hljs-keyword">action</span>(sqlserver.sql_text)) <span class="hljs-keyword">go</span></span></code>
2.3.5 查看正在运行的 Event Session
<code class=" hljs cs"><span class="hljs-keyword">select</span> * <span class="hljs-keyword">from</span> sys.dm_xe_sessions <span class="hljs-keyword">select</span> * <span class="hljs-keyword">from</span> sys.dm_xe_session_events</code>
2.3.6 查看收集到的统计数据
<code class=" hljs sql"><span class="hljs-operator"><span class="hljs-keyword">select</span> top <span class="hljs-number">10</span> * <span class="hljs-keyword">from</span> dbo.region <span class="hljs-keyword">go</span> <span class="hljs-keyword">select</span> * , <span class="hljs-keyword">cast</span>(event_data <span class="hljs-keyword">as</span> xml) <span class="hljs-keyword">as</span> event_data_xml <span class="hljs-keyword">from</span> sys.fn_xe_file_target_read_file(<span class="hljs-string">'E:\data_bu\capture_sql_events*.xel'</span>,<span class="hljs-keyword">null</span>,<span class="hljs-keyword">null</span>,<span class="hljs-keyword">null</span>) <span class="hljs-keyword">where</span> event_data <span class="hljs-keyword">like</span> N<span class="hljs-string">'%region%'</span></span></code>
从结果集我们可以看到，sql_statement_completed这个Event抓到的结果中，包含了Action中我们指定的内容，还包含了其他的一些统计信息：
<code class=" hljs xml"><span class="hljs-tag"><<span class="hljs-title">event</span> <span class="hljs-attribute">name</span>=<span class="hljs-value">"sql_statement_completed"</span> <span

我们在Action里面加入对database_name,和plan_handle的捕捉，可以从结果看到又多出来两个元素：
<code class=" hljs sql"><span class="hljs-operator"><span class="hljs-keyword">create</span> event <span class="hljs-keyword">session</span> capture_sql_events <span class="hljs-keyword">on</span> server <span class="hljs-keyword">add</span> event sqlserver.sql_statement_completed ( <span class="hljs-keyword">action</span>(sqlserver.sql_text,sqlserver.database_name,sqlserver.plan_handle) ) <span class="hljs-keyword">add</span> target package0.event_file ( <span class="hljs-keyword">set</span> filename = <span class="hljs-string">'E:\data_bu\capture_sql_events.xel'</span>, metadatafile = <span class="hljs-string">'E:\data_bu\capture_sql_event.xem'</span> )</span></code>
