Hi Lists According to the Doc as below: *Oracle® Database Application Developer's Guide - Large Objects 10g Release 2 (10.2)* Part Number B14249-01 In Chapter 4 there are 2 graph� 1. LOB values are stored out-of-line when any of the following situations apply: *By default. That is, if you do not specify a LOB parameter for the LOB storage clause when you create the table.* 2. ENABLE or DISABLE STORAGE IN ROW Clause You use the ENABLE | DISABLE STORAGE IN ROW clause to indicate whether the LOB should be stored inline (in the row) or out-of-line. Note: You may not alter this specification once you have made it: if you ENABLE STORAGE IN ROW, then you cannot alter it to DISABLE STORAGE IN ROW and vice versa. *The default is ENABLE STORAGE IN ROW.* Document error? Which one is the TRUTH? or I misunderstanding something? Based on our test, even every LOB has only 2080bytes(less than 4000bytes), LOB is stored OUT of line, but dba_lobs.in_row=YES. -- Kamus <kamusis@xxxxxxxxx> Visit my blog for more : http://www.dbform.com Join ACOUG: http://www.acoug.org -- //www.freelists.org/webpage/oracle-l
