Hey, I'm trying to create a trigger in my Oracle database that changes all other records except the one that has just been changed and launched the trigger to 0. Because I am updating records in the same table as the one that launched the trigger I got the mutating table error. To solve this, I put the code as an anonymous transaction, however this causes a deadlock. Trigger code: CREATE OR REPLACE TRIGGER check_thumbnail AFTER INSERT OR UPDATE OF thumbnail ON photograph FOR EACH ROW BEGIN IF :new.thumbnail = 1 THEN check_thumbnail_set_others(:new.url); END IF; END; Procedure code: CREATE OR

I had an idea that I could write a query to find all the descendent tables of a root table, based on foreign keys. Query looks like this: select level, lpad(' ', 2 * (level - 1)) || uc.table_name as "TABLE", uc.constraint_name, uc.r_constraint_name from all_constraints uc where uc.constraint_type in ('R', 'P') start with uc.table_name = 'ROOT_TAB' connect by nocycle prior uc.constraint_name = uc.r_constraint_name order by level asc; The results I get look like this: 1 ROOT_TAB XPKROOTTAB 1 ROOT_TAB R_20 XPKPART_TAB 2 CHILD_TAB_1 R_40 XPKROOTTAB 2 CHILD_TAB_2 R_115 XPKROOTTAB 2 CHILD_TAB_3 R_50

I am kind of newbie in Oracle. Got stuck in the below: I have the below 2 tables: Site: **SiteID|SiteName** 1 Sydney 2 Newyork 3 Delhi People: **RecordID|PeopleID|SiteID** 1 1 1 2 1 2 3 2 2 4 3 1 5 3 2 6 3 3 Now in my query I want an output something like this: **PeopleID | AssignedSites** 1 Sydney,NewYork 2 Newyork 3 Sydney,NewYork,Delhi Few more points: -The solution should work in Oracle 10g as well as 11g also. -I have given small subset of data in the above example for brevity.But, in my prod scenario, one Person can be associated with 1000+ locations and there could 1000+ such person, so

I have connected Java program to Oracle database using JDBC. I want to store BigInteger values(512 bits) in the database. What should be the type of the column?
