LogMiner returns wrong sql_redo for BLOB data type as shown below:
PRIMARY KEY ("ID")
LOB ("DEVICEOBJECT") STORE AS BASICFILE (
TABLESPACE "USERS" ENABLE STORAGE IN ROW CHUNK 8192 RETENTION
SQL> insert into LOGDEVICE values ('aaa',1);
1 row created.
SQL> delete from LOGDEVICE where id =1;
1 row deleted.
By mining the corresponding redo log the output from v$logmnr_contents shows the following statement for the DELETE sql executed above:( NOTE: the "and" in the where clause):
delete from "QATUSER"."LOGDEVICE" where and "ID" = '1'; >>>>>> we can see "and"immediately after where without a condition.
The correct sql_redo should look like below:
delete from "SCOTT"."LOGDEVICE" where "ID" = '1' and ROWID = 'AAATu8AABAAAZhZAAA';
