In my Netezza box, I can see duplicate records in system tables. It is specific to EXTERNAL TABLE records as shown below
Example:
SYSTEM.ADMIN(ADMIN)=> CREATE EXTERNAL TABLE “Joe” (“Id” integer)
SYSTEM.ADMIN(ADMIN)-> USING (DATAOBJECT(‘filename.csv’)
SYSTEM.ADMIN(ADMIN)(> REMOTESOURCE ‘odbc’);
CREATE EXTERNAL TABLE
SYSTEM.ADMIN(ADMIN)=> select tablename, objtype from _v_table where tablename =’Joe’;
TABLENAME | OBJTYPE
———–+—————-
Joe | EXTERNAL TABLE
Joe | EXTERNAL TABLE
(2 rows)
SYSTEM.ADMIN(ADMIN)=> select tablename, objtype from _v_table where objtype =’EXTERNAL TABLE’;
TABLENAME | OBJTYPE
———————————————————-+—————-
STG_TBLMEMBERS_HIST_EXT_ef8de7e9c2b14692bf61848d5fd20858 | EXTERNAL TABLE
STG_TBLMEMBERS_HIST_EXT_ef8de7e9c2b14692bf61848d5fd20858 | EXTERNAL TABLE
Joe | EXTERNAL TABLE`
Joe | EXTERNAL TABLE
(4 rows)
Even OBJECTID is also same for these 2 duplicate records. I could not found the reason for it. Please help and let me know what could be the reason for it.
Thanks
