Sequence In Select Ignoring Where Clause?
Sep 28, 2011
I want to use a sequence to populate a field for my insert statement. Should be simple right?
So here is an example
insert into sometable ( seq, else)
select
myseq.nextval
,somethingelse
from sometable@dblink
where somethingelse = 10
now if i remove my sequence call for nextval it correctly uses the where clause but when I use the sequence in the select statement it is ignoring the where clause completely. I've never had this issue before...is this because i'm using a dblink now?
I'm using toad 10 on oracle 11g in multi-schema environment.

I have a real problem with form, specifically one of its data blocks. In the order by property of the block i specify it to sort on a branch in ascending order(i tried descending as well) but for some reason the form ignores that and sorts it on the ROWNUM. I even removed the where clause, the order by clause and changed the query data source type to FROM clause and changed the data source name to pre-query. I then created the query string in the block's pre-query trigger and set query_data_source_name property to that query string and still the data in the block is not being sorted on the branch number but instead on the ROWNUM.

sl no department prev year cur year
01 revenue 2000 5000
02 costing 500 1000
03 excise 8000 900
and so on....
I have a created a fomula field for each and every department and get the value from a particular table. What i require is if suppose the department revenue does not have any value then that row should not be visible. for eg if revenue has a null value then the report should be like this
sl no department prev year cur year
01 costing 500 1000
02 excise 8000 900

We have and Upper and a Lower function.Is there any function or way in which I can issue a select while ignoring the case(like IgNoReCaSe) in a where clause? I don't want to use like
select * from emp where upper(job)= upper('dba');
or
select * from emp where lower(job)= lower('dba');
I just want to know if there is any way in which I could do it without using upper and lower.

I have some issues in passing array values to IN clause.
I am passing a String Array from Java to PL\SQL and want to use the Array values in the IN CLAUSE of Select Query
cust_array is the Array
search_id VARCHAR2(1000);
search_id := '';
FOR j IN 1 .. cust_array.count
LOOP
IF (j != 1) THEN
search_id := search_id || ''',''' || cust_array(j) || ''';
ELSE
search_id := search_id || '''' || cust_array(j) || '''';
END IF;
END LOOP;
trying to form a string of below form: search_id '3211335201','3211335209','3211335279','3211335509'
and use the string search_id in the IN clause of the search Query select * from DPP_EMP where empl in (search_id)
but the query does not returns any result
When I try to hardcode the values in the query as below, its returing 4 rows
select * from DPP_EMP where empl in ('3211335201','3211335209','3211335279','3211335509')
How to achieve this (String to the IN clause) or is there a better way of passing the Array values to the IN clause

I'm using pivot query feature of oracle 11g and came across a strange situation where i need to pass a "select statement" in a "in clause" of pivot query.
SQL> CREATE TABLE TEST1
2 (
3 UIN NUMBER(8) NOT NULL,
4 TESTING_ID NUMBER(4),
5 PFA_RESULT VARCHAR2(30 BYTE)
6 );
[code]....
I have tried with pivot xml but it not giving desired output in sql*plus session.It is giving unreadable output.
select * from
(select uin,testing_id,pfa_result from test1)
pivot xml (max(pfa_result) as result
for (testing_id) in (select distinct testing_id from test1));
[code]....
Here actually i want to use "select distinct id from test1" instead of "in (11,12,13,14,15)". Because i don't know how many id's will be there and of which values. e.g. 11 or 21 or 25.

Is there a way to define a SELECT clause once and reuse it in many other queries?
I have many procedures with same SELECT statement and I'm trying to find a way to not have to write out the SELECT clause in every function or procedure. Same question applies to FROM, WHERE, etc clauses.

currently i m going through some dumps for my OCA-11g prep.I came across one sentence :A view cannot have an ORDER BY clause in the SELECT statement.well this statement is false and the explanation given was :
Query operations containing ORDER BY clause are also permitted, so long as the ORDER BY clause appears outside the parentheses.
The following is an example of what I mean: CREATE VIEW my_view AS (SELECT*FROM emp) ORDER BYempno.
but when i tried running the query like this :CREATE VIEW my_view AS SELECT*FROM emp ORDER BYempno ,it worked w/o giving parentheses.

I have created domain indexes on text columns of a materialised view to use "contains" clause when searching for data. The select query with "contains" clause does not return any records, however I was able to retrive data using via regular query using a like search.
-> will exec ctx_ddl.sync_index('index_name')'resolve my problem?
-> since the view is a materialized view, how can i make sure that the latest data added are also picked up?

The below sql is giving different number of result sets while adding further columns in select clause.i.e After adding the columns 4,5,6 in the below query its giving different number of result set.In this case the result set count would be 5.
Before adding the columns 4,5,6,the result set count was 11.
SELECT PAYMENT_METHOD_MAP.NETTINGGROUP_ID,
PAYMENT_METHOD_MAP.CREDITPAYMENTMETHOD_CD,
PAYMENT_METHOD_MAP.DEBITPAYMENTMETHOD_CD,
PAYMENT_METHOD_MAP.AGENT_ID,
SETTLEMENT.NETTINGGROUP_ID,
SETTLEMENT.SETTLEMENTDATE

I am trying to create a tabular form based on a SQL query, that has a query-based select list with a where clause that references a column in the originating SQL query.
The situation is, I have a table that stores client_id, source_id and build_id, lets call it client_source. I have a second table, build_source, that contains source_id and build_id, with a one to many relationship between the two (source_id of 1 could have build_id of 1-7).
Using a tabular form, I want to select the corresponding build_id to be used in client_source, but the select list must only contain the build_id's for that rows particular source_id.
Here is an example of the SQL source of my tabular form;
select
s.ROWID,
s.CLIENT_ID,
s.SOURCE_ID,
APEX_ITEM.SELECT_LIST_FROM_QUERY(1, s.BUILD_ID,
'select b.build_id display, b.build_id return from
build_source b where b.source_id = s.SOURCE_ID ') lst
from client_source s
... what I am trying to achieve is that the source_id fields in bold match. When the query is built this way I get an 'invalid identifier' Oracle error on s.SOURCE_ID at runtime.
Is there some special tags that need to be used to reference the outside column?I am running on Application Express 4.1.0.00.32, on a Oracle 10g release 10.2.0.4.0 database.

I have created a trigger for after insert which updates a table when there is a row inserted in that table. The update is on a column which stores the application description along with the sequence number. Now my requirement is that sequence number should be unique only with in an application but not with in the table.Say the row entry can be as follows:
App_Desc Request_ID
-----------------------
DEV 100 1
DEV 101 2
STG 100 3
STG 101 4
Here Request_ID is unique But the sequqnce thats created for DEV (100,101) should take an entry of 102 for the next entry for DEV and same applies for STG. So I have to use the same sequqnce for all the application.

I have 3 tables whose structure is as follows:
1) Invoice
Invoice_no number(8),
Debtor varchar2(35),
Invoice Date Date,
Print Date Date,
Currency varchar2(3),
Total Amount Ex Number(11,2),
Total Amount Vat Number(11,2),
Total Amount Number(11,2),
Status Varchar2(15),
2) Invoice Line
Invoice_no number(8),
Invoice_Line_No number(8),
Description_1 varchar2(35),
Description_2 varchar2(35),
Line_Quantity Number(11,2),
Currency varchar2(3),
Line_Amount Number(11,2),
Vat Code number(1),
Status Varchar2(15),
3) vat code
vat code number(1),
Description varchar2(35),
Vat Percentage number(11,2)
Here invoice no and invoice line no are automatically generated fields?
How to generate invoice line no corresponding to invoice no and how to satisfy the following conditions:
1) total vat amount in invoice table should be automatically filled . total vat amount=(line_quantity* line_amount*vat percentage)/100
2) invoice cannot be printed, changed when status is 'closed'.
3) invoice lines cannot be added,changed or removed when status of invoice is closed
4) when any of invoice line no is changed,added, removed or invoice is changed the status of invoice should be changed to 'new'.
5) invoice date of a new invoice cannot be of the past

For some reason Oracle Sequence is skipping the first value. Here is an example of script.
drop sequence tseq;
drop table xyz;
create table xyz
(sno integer);
create sequence tseq
start with 1;
insert into xyz values (tseq.nextval);
select * from xyz;
Now the runtime of the script in SQL Developer:
drop sequence tseq succeeded.
drop table xyz succeeded.
create table succeeded.
create sequence succeeded.
1 rows inserted
SNO
----------------------
2
Why is it skipping the starting value 1. Is there something new in 11g that is causing it to skip the first value. I have many scripts and they all are having errors due to this issue.
