Here is some more forensic/investigative code. Suppose you need to make sure a value gets in a certain column, but you don’t know the system at all.
Maybe there is a trigger or stored proc that sets the column based on some other table/column. This code gives you a list of all the stored procedures, triggers, and functions (and even views) that use that column name (or any string field).

Create table #temp1 
(ServerName varchar(64), dbname varchar(64)
,spName varchar(128),ObjectType varchar(32), SearchString varchar(64))

Declare @dbid smallint, @dbname varchar(64), @longstr varchar(5000)
Declare @searhString VARCHAR(250)

set  @searhString='OpenDate'

declare db_cursor cursor for 
select dbid, [name] 
from master..sysdatabases
--where [name] not in ('master', 'model', 'msdb', 'tempdb', 'northwind', 'pubs')
where [name] in ('MyDatabase') 

open db_cursor
fetch next from db_cursor into @dbid, @dbname

while (@@fetch_status = 0)
    PRINT 'DB='+@dbname
    set @longstr = 'Use ' + @dbname + char(13) +        
        'insert into #temp1 ' + char(13) +  
        'SELECT @@ServerName,  ''' + @dbname + ''', Name 
        , case  when [Type]= ''P'' Then ''Procedure''
                when[Type]= ''V'' Then ''View''
                when [Type]=  ''TF'' Then ''Table-Valued Function'' 
                when [Type]=  ''FN'' Then ''Function'' 
                when [Type]=  ''TR'' Then ''Trigger'' 
                else [Type]/*''Others''*/
        , '''+ @searhString +''' FROM  [SYS].[SYSCOMMEnTS]
        JOIN  [SYS].objects ON ID = object_id
        WHERE TEXT LIKE ''%' + @searhString + '%'''

 exec (@longstr)
 fetch next from db_cursor into @dbid, @dbname

close db_cursor
deallocate db_cursor
select * from #temp1
Drop table #temp1

Code from: StackOverflow

When you come to a new client, and have try to fix bugs or figure out how the system works, it helps to have some “forensice” SQL tools. Suppose you want to find all columns in a database, regardless of which table they are (and of course, show the table name in the query results). In my case, I was dealing with PickupDateTime, but the screen was showing two fields, a from and to date/time. So I wanted to look for all columns that start contain both “pickup” and “from” in that order.

Use MyDatabaseName 
SELECT AS table_name,
SCHEMA_NAME(schema_id) AS schema_name, AS column_name
FROM sys.tables AS t
WHERE LIKE '%pickup%from%'
ORDER BY schema_name, table_name;

Example code came from Dave Pinal’s SQL Blog.

Suppose you want to know what BizTalk Orchestrations are bound to a send port.
Perhaps you ran my query to list send ports related to a receive port.

NOTE: Still experimental code; haven’t verified much.

 rp.nvcName as 'ReceivePort',
 op.nvcName as 'OrchPort',
 o.nvcName as 'Orchestration'
 --pto.nvcName as 'PortTypeOperation',
 from bts_receiveport rp 
 inner join bts_orchestration_port_binding opb  on rp.nID = opb.nReceivePortID 
 inner join bts_orchestration_port op on op.nID = opb.nOrcPortId --and op.nPortTypeID in (1,9) -- recieve ports only  (9 = activating receive) 
 inner join bts_orchestration o on o.nID = op.nOrchestrationID  
--where rp.nvcName like '%ABC%' 

See also the query on this page to do similar by message type:

How do you find the hidden map name in the BiztalkMgmtDB (BizTalk Database)?

If you look at the table names, you will obviously find bt_MapSpec, but it doesn’t contain the map name. The map itself is hidden in the bts_Item table, which you have to join to. I found this on Jeroen Maes Integration Blog. He has a more complex query that finds a map based on the input/output target namespace. He also joins to the bts_Assembly table.

My goal was just to list all maps containing some sequence of letters (such as a customer name or abbreviation).

use BizTalkMgmtDb
select, * from bt_MapSpec  m 
inner join bts_item i on m.itemid =
where i.Name like '%ABC%'         -- just the map name 
-- where i.FullName like '%ABC%"  -- optionally use the fully qualified name 

I’m surprised there the Type column doesn’t seem to be populated with some number that indicates that the bts_Item is a map, or a schema, or whatever.

You can turn on message tracking in BizTalk at the Receive Port and Send Port level (as well as various levels in the orchestration).

Here are the views provided by the BizTalk install.

use biztalkDtaDb
--select * from TrackingData 
--select 'btsv_Tracking_Fragments', * from btsv_Tracking_Fragments
select 'btsv_Tracking_Parts', * from btsv_Tracking_Parts 
select 'btsv_Tracking_Spool', * from btsv_Tracking_Spool 

To get the Send/Receive port or more info about the message, you need to join to dtav_MessageFacts. The idea for this join came from sample code here.

SELECT top 200
      CONVERT(VARCHAR(10), a.[Event/Timestamp], 111)   as [date],
      DATEPART(HOUR,a.[Event/Timestamp]) as [Hour], 
FROM [dbo].[dtav_MessageFacts] a
inner join dbo.btsv_Tracking_Parts b on a.[MessageInstance/InstanceID] = b.uidMessageID

Note: Later I added this line (not shown in picture).  You have to use DataLength() instead of Len() to get the size of an image field. 
DataLength(imgPart) as Length,

The body of the message is stored in imgPart of the btsv_Tracking_Parts view, but unfortuantely it’s in Hex.
The following site is one that can convert the hex to ascii (might also need one to go to Unicode). Paste the hex data in the top, click convert, and your text will appear in the bottom half. You won’t be able to see it all, but you can copy/paste to NotePad++ or some other editor.

While it’s nice to use the built-in features of BizTalk when possible, they will typically have limitations compared to custom options. In a few places where I worked, we implemented our own “Trace” that writes data to a SQL trace table. We had our own concept of promoted fields to identify the trace, such as the location where the trace was capture (pipeline, orchestrations, before/after map, etc), a user type key, and a correlation token that can tie together traces across an entire business process.
