The the description is somewhat vague:

Exclusive LOCK happens on process basis not by user !
It's not clear where you run "export from the production". Portal,Terminal, Studio, ...

if you are in Studio and run "export from the production" in MgmtPortal or Terminal then you have 2 processes.
1 has the lock the other can't get it.
 

take a look in MgmtPortal >  System Operation > Locks  > View Locks

Now you should see who is owning your lock

BTW. Class %ZEN.Component.querySource  still does it as iit did in past.

For more tricky manipulation you have

/// (optional) Name of Server-side callback method to call to create
/// a <class>%ResultSet</class> object.<br>
/// This must be the name of a server-only method in the page
/// class that contains this component.
Property OnCreateResultSet As %ZEN.Datatype.delegator(FORMALSPEC = "*tSC:%Status,pInfo:%ZEN.Auxiliary.QueryInfo", RETURNTYPE = "%ResultSet");

/// (optional) Name of Server-side callback method to call to execute the
/// <class>%ResultSet</class> object.<br>
/// This must be the name of a server-only method in the page
/// class that contains this table pane.
Property OnExecuteResultSet As %ZEN.Datatype.delegator(FORMALSPEC = "pRS:%Library.ResultSet,*tSC:%Status,pInfo:%ZEN.Auxiliary.QueryInfo", RETURNTYPE = "%Boolean");

yeah, table navigators chop the original resultset.

but with the absolute rowID (%vid) and the pageSize (pS)  you should get pageNum= %vid\pS+1
and relative rowID= %vid#pS

Or directly in SQL  with pageSize = 12

SELECT *, %vid AbsRowID,
                    CEILING(%vid/12) PageNum,
                   {fn MOD(%vid,12)} RelRowId from (
      SELECT name,home_city TOWN FROM Sample.Person
) WHERE TOWN %STARTSWITH 'DENVER'

you will keep the * away as you don't need the content

It's all based on the fact that the 'base'query always generates the same sequence of rows 
Just dynamic filters may break this. 

For paging also tablePane has to use the same mechanics.

Hi Chip,

If I understand it correct you have a value and look for the related rowID in your tablePane.

tablePanes get typically feeded by a well know SQL SELECT and it numbers its rows sequentially.

For ease of explanation,  I use  SELECT name,home_city TOWN FROM Sample.Person  to fill your tablePane

Let's look for TOWN = 'Denver'

SELECT *, %vid rowID from ( 
      SELECT name,home_city TOWN FROM Sample.Person
) WHERE TOWN %STARTSWITH 'DENVER'

Of course, there is still arithmetic required if you have several sections to calculate.
This just gives you the 'absolute' rowID, not the relative.
HTH, Robert

the DSN is used when you set up your SQLgateway connection.

MgmtPortal > System > Configuration > SQL Gateway Connections

 There all information  on the DSN is stored.

Next if you Link the external table this gateway entry is used and stored for access.

MgmtPortal > System Explorer > SQL > Wizards > LinkTable

Now you bind a Class in a Namespace to a Gateway to a DSN


  

So you are fixed for THIS namespace. This is static.
If you change the Gateway entry or the DSN in some essential way
it could happen that you have to do this again.

Similar for a different target table you have to do the Link again.

A different issue could be that you might just have read access to the foreign table.
Then I'd expect some kind of error message.
At least it is something the partner side has to manage.

doc for ORA-01861
describes the TO_Date issue very detailed

https://www.techonthenet.com/oracle/errors/ora01861.php

Your problem seems to be strictly related that the value you use and its description in TO_DATE don't match.

So TO_DATE(?,'YYYYMMDD') in Prepare
should work with 
    s result=obj.%Execute(20180425,par2,par3,par4)

It's a little bit less transformations

Robert Cemper · Apr 24, 2018

Through terminal couldn't make it work no mater what i tried, not when it is %Date and using $h without to_date nor when it is %String and translating the date to yyyy-mm-dd with or without to_date (at prepare or at execute).

Did you also try SQL shell from terminal ?  (it should act like SMP)
SAMPLES>Do $system.SQL.Shell()
SAMPLES>>INSERT INTO .......

Also: have you ever checked status  ?   to see if  %Prepare was OK ?

after:

s status=obj.%Prepare(statement)

do $system.OBJ.DisplayError(status)

It's hidden in your example

Robert Cemper · Apr 23, 2018

The change from %Date to %String influences image of your target table
and may affect implicit ODBC Data transmission that converts eg. +$h to YYY-MM-DD format !

once your data is a %Date again this should do it:
...... VALUES (?,?,?,?)
%Execute($zdh(somedateYYYYMMDD,8),par2,par3,par4)

If you test in SMP you have to check if you are in ODBC, Logical or Display mode.
with TO_DATE() you just overrule this as string are the same in any mode.

For ODBC the date is always 2018-04-25
For Display it's 04/23/2018 or 23.04.2018 depending on your local setting
For Logial it is always 64761 (+$h)

OK.
you got a reply of 149 characters!

And what was the result of ZZDUMP tText?

It should look similar to  this:

I filled in the marked characters to get to your received size. The real value could help as there is a bunch of controls that could trigger a newline.

The thing looks somehow encoded / encrypted or just binary.
Do you have information on source system ?   (the url is definitely faked)

Classes and Methods forever!

#1) for documentation
#2) for all the possibilities and structural controls of  OO development.
 

#3)
.mac & .int is a left over from a previous millennium,
a (failing) attempt to mimic OO with the mindset of procedural methodology.

I'm personally disappointed that Atelier still supports mac.

It was a historical requirement. Accepted. For last millennium. Eventually still for some internals.
Definitely not for public use.

Robert Cemper · Apr 20, 2018

you didn't get me. The browsers make something unreadable and useless out of it.

That's just rubbish

pls do:

SET tText = tHttpResponse.Data.Read()
ZZDUMP tText
WRITE tHttpResponse.Data.Size

So we see the real HEX_content , eventual control characters, ...  and the received number of characters
Similar to your request the response is encrypted. Eventually,  it can be decoded.
