He Zhenxing updated TRAFODION-3279:
-----------------------------------
Description:
When mixing lob and normal columns like this:
{noformat}
>> cqd traf_blob_as_varchar 'off';
>> create table t1 (a int, b blob);
>> create table t2 (a blob, b int, c blob);
{noformat}
try get lob stats will fail with this error:
{noformat}
>> get lob stats for table t1
*** ERROR[4082] Object TRAFODION.SCH."LOBDescChunks__02697841542402152109_0001"
does not exist or is inaccessible.
*** ERROR[8822] The statement was not prepared.
--- SQL operation failed with errors.
>> get lob stats for table t2
*** ERROR[4082] Object TRAFODION.SCH."LOBDescChunks__02697841542402158348_0002"
does not exist or is inaccessible.
*** ERROR[8822] The statement was not prepared.
--- SQL operation failed with errors.
{noformat}
It seems it will wrongly used the lob number as the lob column number.
Please note that showddl <table>, lob detail command is not affected, but
select * from table(lob stats(<table>)) suffer the same problem.

It seems it will wrongly treat the normal columns before blob column as a blob
column.
