DB2 FOR LUW / DB2FORLUW / 970 - DB2

When attempting to modify both the table attribute (e.g. row 
compression) and column inline length within the same ALTER 
TABLE statement, the system catalog is updated with the new 
inline length but no actual changes are applied on the physical 
inline length. However, the change to the table attribute will 
be taken effect. 
 
Example: 
 
db2 "create table t1(i int, c clob(2000))" 
db2 "alter table t1 compress yes alter column c set inline 
length 1000" 
db2 insert ...  # inserting data 
db2 "select i, admin_is_inlined(c) is_inlined from t1" 
 
I           IS_INLINED 
----------- ---------- 
         10          0 
 
  1 record(s) selected. 
 
 
db2 "select char(colname,20) column_name, char(tabname,10) 
table_name, inline_length from syscat.columns where tabname = 
'T1'" 
 
COLUMN_NAME          TABLE_NAME INLINE_LENGTH 
-------------------- ---------- ------------- 
C                    T1                  1000 
I                    T1                     0 
 
 
Local Fix: 
Running the alterations in separate ALTER TABLE statements. 
 
db2 alter table t1 compress yes 
db2 alter table t1 alter column c set inline length 1000 
db2 "select i, admin_is_inlined(c) is_inlined from t1" 
 
I           IS_INLINED 
----------- ---------- 
         10          1 
 
  1 record(s) selected.
