  I am having data format issue. I have a table where the date column is defined as the format "yyyy/mm/dd" and when I am selecting from this table and doing substr it is giving correct result.  


I doubt there's a need to substring a DATE, it's usually more efficient to use EXTRACT, etc.

Could you show what you actually do?


  But I have complex transformation so in between I am inserting the data in a volatile temporary table where the data format is changing to "yy/mm/dd", though in the select I have specified the format as "yyyy/mm/dd". Because of this change of format all the sub-strings are working wrongly.  


Your system default is set to 'yy/mm/dd' (Integerdate) and the FORMAT is apparently not carried over to the Volatile Table.

Changing the dateform on session level should work:

     SET SESSION DATEFORM = ANSIDATE;
