I have a two tables with same column name , I wanted to find different record in table1 when compared with table2
create table table1(col1 number,col2 number,col3 number,col4 number,col5 number);
create table table2(col1 number,col2 number,col3 number,col4 number,col5 number);
insert into table1 values(1,2,NULL,NULL,NULL);
insert into table2 values(1,2,NULL,NULL,NULL);
commit;
select col1 from (select col1,col2,col3,col4,col5 from table1 minus select col1,col2,col3,col4,col5 from table2);
no rows selected
how come i get no rows selected when col3,col4,col5 is having null values but NULL could be anything so
NULL-NULL cannot be equal to zero how is it possible

I have a requirement in SQL that I have to number each row. Hence I thought of using ROWNUM. But the sql query I'm using uses UNION operator. Hence I used like this
select a,b,rownum as 'field1' from table1
union
select c,d,1 as 'field1' from table2
Will the above query solve my purpose?

Query -
SELECT *
FROM sysadm.ps_tmtl_post_vw a
WHERE a.month_prepared_for = 'JUNE,2012'
AND a.ca_status = 'P5 CUST GO AHEAD'
[code]...
When I try for the SQL-Tuning sets its throws error that
ADDITIONAL INFORMATION SECTION
-------------------------------------------------------------------------------
- The optimizer could not merge the view at line ID 2 of the execution plan.
The optimizer cannot merge a view that contains a set operator.
I read earlier forum where it says that optimizer unable to interpret the conditions like order by etc etc.Now there is one view which is getting used in the query when I did select * from vw it took more than 16 hrs to complete. (bad view).

The following runs no problem
SELECT
ACCO.SEQUENCE,
ACCO.DESCRIPTION,
MAX (ACCO.AUDIT_DTE)
FROM
PAS.AUDIT_CLINICAL_CARE_OPTIONS ACCO
WHERE
ACCO.AUDIT_DTE < :AuditDate AND
[code]....
However, when I try to add extra conditions to the status' in the sub select i get the error. This is one way I tried:
SELECT
ACCO.SEQUENCE,
ACCO.DESCRIPTION,
MAX (ACCO.AUDIT_DTE)
FROM
PAS.AUDIT_CLINICAL_CARE_OPTIONS ACCO
WHERE
[code]....
I've tried repeating the sub select for each of the extra status parts but everytime i hit the same problem.

I have a package function which is wrapped and I cannot see the code.The package function raises an user-defined exception when :
SELECT ABC.*
FROM ABC
WHERE ABC.A = PACK.FUNC(ABC.B,ABC.C)
But it does not raise any exception and the query works absolutely fine generating desired results when :
SELECT ABC.*
FROM ABC
WHERE ABC.A = (SELECT PACK.FUNC(ABC.B,ABC.C) FROM DUAL)

I want to link to blocks using description as there is no relation , for example i have two tables with one field in common called description, and i want to link this field in two tables using like operator.
create table item ( item_code varchar2(12),item_name varchar2(30));
insert into item VALUES('A','HEA160');
insert into item VALUES('B','HEA180');
create table stk (sl_item varchar2(12),sl_desc varchar2(30),sl_qty number);
insert into stk VALUES ('X','HEA160X1000',12);
insert into stk VALUES ('X','HEA160X2000',4);
insert into stk VALUES ('Y','HEA180X3000',10);
Suppose i click on item block item_desc with value on HEA160 all the items similar to that should appear in stk block like 'HEA160X1000' ,'HEA160X2000' , if i click on 'HEA180' on item then 'HEA180X3000' it should come.

I am trying to use the REGEXP_LIKE and I am getting ORA-00920: invalid relational operator.
I have run very simplified code to try to sort it out but no success:
SELECT id, address
FROM test_lob_tab
WHERE REGEXP_LIKE(address,'^A');
select 1 from dual where regexp_like('123', '^[0-9]$');
same result from both.
I am using Oracle 11 and freetoad 11.

I'm creating Tool Tip definitions for the Operators in the Filter on the Interactive Reports. I was looking for a definition for the 'Contains' operator and from what I've found this operator is used to do a text search and it returns a relevance score for every row selected.
I've also read that in order for that score to be determined that the column(s) need to be indexed with a CONTEXT index. Non of the columns in the tables are indexed with a CONTEXT index, however, when I put a value in the Expression box for a column I get a record returned.
If I run the same query in PL/SQL Developer like:
SELECT <column>
FROM <table>
WHERE contains(<column>,<search text>,1) > 0;
I get an error that the column is not indexed, so how does it work in APEX?

if on an interactive report, you try and filter on a date column, then the "=" operator disappears.You get other (not so useful) operators like "in the next", "not in the next" ">", ">=" etc. - but no "=" to be found.
