从 SSIS/DTSX 包中提取 SQL 语句 [英] Extracting SQL statements from a SSIS/DTSX package

问题描述

我正在寻找一些东西来提取我的 SSIS/DTSX 包中存在的所有 SQL 查询.但到目前为止，没有什么能帮到我.

I am looking for something to extract all the SQL queries present in my SSIS/DTSX package. But nothing is helping me till now.

我已经看过来自 Microsoft 的 Microsoft.SqlServer.DTS API.但是他们正在直接提取一些查询.但是存在于 DTS:variable TAG 中的查询不会被提取.

I already had a look at Microsoft.SqlServer.DTS API's from Microsoft. But they are extracting some queries straight forward. But the queries that are present in DTS:variable TAG, they are not extracted.

我想要 .Net 框架中的东西.因为我还需要使用输出来执行其他一些任务.我正在使用 C#.

I want something in .Net framework. As i need to use the output to perform some other task as well. I am using C#.

示例代码如下.不能解决所有情况

Sample code as follows. Does not address all the situations

// this function takes the list of task hosts as input
// and gives all the queries present in taskhosts.

public static string ExtractQueriesFromTasks(List<TaskHost> Tasks)
{
    string src_query = "";
    foreach (TaskHost executable in Tasks)
    {
        DtsContainer Seq_container = (DtsContainer)executable;
        if (executable.InnerObject.GetType().Name == "ExecuteSQLTask")
        {
            ExecuteSQLTask sqlTask = (ExecuteSQLTask)executable.InnerObject;
            string src_query2 = sqlTask.SqlStatementSource;

            src_query = src_query + "\n" + src_query2.ToUpper();
        }
        if (executable.InnerObject.GetType().Name == "__ComObject")
        {
            IDTSPipeline100 sqlTask = (IDTSPipeline100)executable.InnerObject;
            Console.WriteLine(Microsoft.VisualBasic.Information.TypeName(executable.InnerObject));
            //ExecuteSQLTask sqlTask = (ExecuteSQLTask)executable.InnerObject;
            //string src_query2 = sqlTask.SqlStatementSource;

            //src_query = src_query + "\n" + src_query2.ToUpper();
        }


        if (executable.InnerObject.GetType().Name == "ScriptTask")
        {
            ExecuteSQLTask sqlTask = (ExecuteSQLTask)executable.InnerObject;
            string src_query2 = sqlTask.SqlStatementSource;

            src_query = src_query + "\n" + src_query2.ToUpper();
        }
    }
    return src_query;
}

推荐答案

以下查询有助于检索 SSIS 包内的所有 sql 语句

;WITH XMLNAMESPACES ('www.microsoft.com/SqlServer/Dts' AS  
DTS,'www.microsoft.com/sqlserver/dts/tasks/sqltask' AS SQLTask) 

-- Query to Extract SQL Tasks with Name and SQL Statement 
SELECT Pkg.props.value('../../DTS:Property[@DTS:Name="ObjectName"]
[1]','varchar(MAX)') ObjectName, 
Pkg.props.value('(@SQLTask:SqlStatementSource)[1]', 'NVARCHAR(MAX)') AS 
SqlStatement FROM (select cast(pkgblob.BulkColumn as XML) pkgXML from 
openrowset(bulk 'Your DTS package with name and location Path',single_blob) 
as pkgblob) t CROSS APPLY pkgXML.nodes('//DTS:ObjectData//SQLTask:SqlTaskData') Pkg(props) 
UNION 

-- Query to Extract DTS Pipline task with Name and SqlCommand 

SELECT Pkg.props.value('../../../../DTS:Property[@DTS:Name="ObjectName"]
[1]','varchar(MAX)') ObjectName, 
Pkg.props.value('data(./properties/property[@name=''SqlCommand''])[1]', 
'varchar(max)') SqlStatement FROM(select cast(pkgblob.BulkColumn as XML) 
 pkgXML from openrowset(bulk 'Your DTS package with name and location 
 Path',single_blob) as pkgblob) t CROSS APPLY 
pkgXML.nodes('//DTS:Executable//pipeline//components//component') Pkg(props) 
WHERE Pkg.props.value('data(./properties/property[@name=''SqlCommand''])
[1]', 'varchar(max)') <>''
