I have a sql query as below :
select order_number,
(select decode(hcp.contact_point_purpose,'ABC',hcp.email_address,'CDE',hcp.email_address,null)
from hz_contact_points,
hz_parties hz
WHERE hz.party_id=hcp.owner_table_id) Email
FROM oe_order_headers_all h
WHERE h.order_number='102'
....................
..............
Actually the problem i am facing is the inner select query is returning multiple row , so my main query is erroring out, i need to capture the multiple row.
In the above example the inner decode statement returning two mail address, I need to capture that, but while executing the whole query it is erroring out as saying single query returns multiple values. capture multiple values

At my Workplace we have a large Orcle 11g Database with 30 different tables for production control issues.I try to get a couple of different information from the database, so i started with SQL Query's, but for this problem i was not able to write an working query.
In this case i have 2 tables:
Table 1:
ID ;ORDER_NR ;DESCRIPTION ;CREATE_DATE
1 ;A500236 ;CLEAN HOUSE ;02/20/2012
2 ;A623555 ;REPAIR CAR ;01/10/2012
3 ;A866944 ;MAINTAIN EQUIPMENT ;02/11/2012
Table 2:
ID;ORDER_NR;WO_STEP;STEP_DATE;EMPLOYEE
1;A500236 ;A;02/21/2012;W0010
2;A500239 ;F;02/21/2012;W0010
3;A500239 ;S;02/22/2012;W0027
[code]....
And the result of my Query should look like this:
ORDER_NR;DESCRIPTION ;CREATE_DATE;A_STAT_AGE;R_STAT_AGE;U_STAT_AGE
A500236;CLEAN HOUSE ;02/20/2012 ;5 ;3 ;1
A623555;REPAIR CAR ;01/10/2012 ;42 ;39 ;38
A866944;MAINTAIN EQUIPMENT ;02/11/2012 ;15 ;4 ;3
The age of my query result should be calculated from the Create date of the Order.I want to know 2 things, one is how old was the Order when they reached that status A, R and U.The second this ist, how long did the order remain on the stat A,R and U (and if possible all other status also)It could happend that not each order reaches each status, so it ca go directly from A to you in this case i want display a wildcard in this row/column

Using Oracle 11gR2 on windows 7 client. I have a question on calculating sum() on multiple columns on different columns and store the results in a view. Unfortunately I could not post the problem here as it keeps on giving error "Sorry, this content is not allowed", without telling where or what it is! So I had to post it in the stack-overflow forum, here is the link: [URL] .........

How to merge multiple rows into single row (but multiple columns) efficiently.
For example
IDVal IDDesc IdNum Id_Information_Type Attribute_1 Attribute_2 Attribute_3 Attribute_4 Attribute_5
23 asdc 1 Location USA NM ABQ Four Seasons 87106
23 asdc 1 Stats 2300 91.7 8.2 85432
23 asdc 1 Audit 1996 June 17 1200
65 affc 2 Location USA TX AUS Hilton 92305
65 affc 2 Stats 5510 42.7 46 9999
65 affc 2 Audit 1996 July 172 1100
where different attributes mean different thing for each Information_type. For example for Information_Type=Location
Attribute_1 means Country
Attribute_2 means State and so on.
For example for Information_Type=Stats
Attribute_1 means Population
Attribute_2 means American Ethnicity percentage and so on.
I want to create a view that shows like below:
IDVal IDDesc IDNum Country State City Hotel ZipCode Population American% Other% Area Audit Year AuditMonth Audit Type AuditTime
23 asdc 1 USA NM ABQ FourSeasons 87106 2300 91.7 46 85432 1996 June 17 1200
65 affc 2 USA TX AUS Hilton 92305 5510 42.7 46 9999 1996 July 172 1100

10 Hi Deepak, My designation id is dsha21. Thanks Rohit
Now I tried to replace the value for "Deepak","dsha21" and "Rohit" using nested replace function and I succeded but that was for static. Now while creating SQL procedure where I am going to make the values of "Deepak","dsha21" and "Rohit" some static variables. I want to pass the values to be replaced with static parameter.
If I give you simple example of my requirement that would be example of a sms send to all customers by a telephone company. Content is same only the Name of customer is replaced everytime.

CREATE TABLE T1 ( id NUMBER,
START_date DATE,
end_date DATE,
end_date1 DATE,
end_date2 DATE,
end_date3 DATE,
LEVEL1 number
)
/
[Code]...
I have data in the first table as mentioned above I need to insert multiple rows into the second table for the same ID depends on the level, If it is level 1 then two rows for same ID first reocrd start_date as the start_date and end_date as end_date from the table t1 for second record start_date is end_date in t1 and end_date for this record is end_date1 column in table t1.
If the level is 3 then the table t2 should have four records for one id and the phase is the value for each record for one ID for example in level 3 we have 4 records for one id and phase should be 1,2,3,4.

I have a scenario where the requirement is to create a "SEQ NO". Based on the 'Tasks' & it's creation date. Where there are multiple 'tasks' for a single SR.
The following example will make it clear
SR TASK Created on SEQ NO
11009 2345 14/10/1988 12:15:17 1
11009 2346 14/10/1988 12:15:57 2
11234 - - -
If there is a SR which has no task then the SEQ NO should be 0. And the seq no should be in the order of the created on field & if 2 tasks are created at the same time i.e suppose 2345 & 2346 have the same time stamp then the SEQ no should be 1,2 respectively n not both as 1.

My current system have 1 submit button with single form. This submit button will call *file_content.upload*.
htp.p('function on_submit() {');
htp.p('...the rest of my code here..');
htp.p('document.forms[0].submit();');
htp.p('return true;');
htp.p('}');
htp.p('<form enctype="multipart/form-data" method="post" action="file_content.upload">');
htp.p('...the rest of my code here..');
htp.p('<input type="button" id="btn_Submit" value="Submit" onclick="on_submit()"></form>');
My question is, i want to enhance this by adding additional 1 submit button with value "Save". But this new "Save" button will call/trigger different file. This new button will call *file_content.update*. How to accomplish this and how to differentiate these 2 button?
htp.p('<input type="button" id="btn_Submit" value="Submit" onclick="on_submit()">
<input type="button" id="btn_Save" value="Save"></form>');

Updating multiple ROWS with different values using single statement. Requirement is to update one column in a table with the values in the other table.
Say we have 3 tables, CORPORATION,CORPORATE PROFILE and MEMBER.
Each MEMBER has CORPORATE PROFILE which in turn is associated with CORPORATION. Now I need to update MEMBER table with CORPORATION identifier for members who belong to corporations with identifiers say 'ABC' and 'DEF'.
MEMBER table contains column 'CORPIDENTIFIER '. CORPORATEPROFILE table contains MEMBERID and CORPORATIONID,this will associate a member with the corporation. CORPORATION table contains ID and CORPIDENTIFIER.
Using the below query I am getting error,ORA-01427:single-row subquery returns more than one row
UPDATE MEMBER M SET M.CORPIDENTIFIER=
(SELECT A.IDENTIFIER FROM CORPORATION A,CORPORATEPROFILE B
WHERE B.CORPORATIONID=A.ID AND B.MEMBERID=M.ID AND (A.IDENTIFIER LIKE 'ABC' OR A.IDENTIFIER LIKE 'DEF'))
Sub query in the above query returns multiple rows and hence it is throwing the error.More than one members are associated with Corporations ABC and DEF. Is there any way possible to update all the rows in single query with out iterating the result set of sub query.

I have a flat file as source wherein I am getting values like
Comp_id, Comp_name, ISIN, column_name, column_value
The structure is like this may contain multiple records like Comp_id, Comp_name, ISIN will be same, but column_name will contain the column_name to which its corresponding column_value needs to be populated to.
E.g. of Feed File -
Comp_id, Comp_name, column_name, column_value
1,HSBC,branch_name,HSBC-DELHI
1,HSBC,branch_add,24-Lajpat Nagar
1,HSBC,branch_phone,2322322
2,HSBC,branch_name,HSBC-MUMBAI
2,HSBC,branch_add,24Andheri
2,HSBC,branch_phone,4445221
2,HSBC,branch_postalcode,400023
Target table structure
Comp_id, Comp_name, branch_name, branch_add, branch_phone, branch_postalcode
I need to insert the above data to a table by selecting data from above scenario.
