what is use of (..) double dot in sql server stored procedure
<p>I have got a script of stored procedure from my senior, like :</p>

<pre><code>BEGIN
EXEC dbo.sp_executesql @statement = N'create procedure [dbo].[up_transfer_data_from_isfoc_to_unicode_sp]
as
begin
declare @errx as int
begin try   

truncate table u_lrc..dir 
truncate table u_lrc..k_2 
truncate table u_lrc..k_name 
truncate table u_lrc..k_gata 
truncate table u_lrc..order1 
truncate table u_lrc..remark 

  insert into u_lrc..dir 
 select code,[lrc].name 
 from lrc..dir
</code></pre>

<p>Where dir, K_2, k_name and others are Table names whereas lrc and u_lrc are databases. u_lrc is a copy of lrc database.</p>

<p>What is (..) is doing here and examples of its usage ?</p>
