I was traveling last week, so I didn't get to spend much time on this.
 
While searching salesforce.com I discovered that you can override the POST method with an arbitrary method name by appending to the URL.

Append "?_HttpMethod=PATCH" and Bob's your uncle!

I had (but lost) some VIs that were knock-offs of the DB Tools List Table and the related Schema VIs. I recreated them fairly quickly this morning.
 
These schema queries return all of a type for a DB, which includes internal. Your tables and views will normally be of a type "dbo". You will have to filter for those in LV. I tried to query my DB for procedures and I did not see a column to filter between system and my own.
 
Google the selected Schema type to get the column names, but most are fairly obvious.
 
If you need to create typdefs for a collection of tables, you can use this scripting VI that I uploaded on the NI Community forums a while back.

1. Is Test stand is completely new programming language than LabVIEW?
 
TestStand is not a programming language. It is a test executive.
 
It is more like Excel in that it implements expressions and conditional logic.
 
TestStand is combined with a language like LabVIEW, CVI, HTBasic etc... to create a test solution.
 
These languages are invoked as steps by use of an TestStand adapter.

It is also possible to use a script with an executable such as Perl, Python or TCL to perform tests.
 
2. How to convert Test stand program to LabVIEW and LabVIEW to test stand back?
 
Since TestStand is not really a programming language, there is no direct/simple way to convert to/from LabVIEW.
