SQL dateFormat Query

Hi All,
I have a sql query which returns me the start and end time of certain process, i just need another output being displayed beside, which gives me the difference of end time and start time, im able to do that by just subtracting end time minus start time, but the difference returns me null.
i have pasted the query below,
select PROCESS.START_TIME, PROCESS.END_TIME, (PROCESS.END_TIME-PROCESS.START_TIME)As Difference from DOCKETS_PUB.PROCESS
this difference column returns me null, im doing this in a dbvisualizer.
Any help on this would be appreciated.
Thanks,
Nandhini

NandhiniWhat are the data types of END_TIME and START_TIME?
Show (copy and paste) the results from a sqlplus command prompt ... cut out the possibility of your client doing something for/to you.

Oracle SQL Select query takes long time than expected.

Hi,
I am facing a problem in SQL select query statement. There is a long time taken in select query from the Database.
The query is as follows.
select /*+rule */ f1.id,f1.fdn,p1.attr_name,p1.attr_value from fdnmappingtable f1,parametertable p1 where p1.id = f1.id and ((f1.object_type ='ne_sub_type.780' )) and ( (f1.id in(select id from fdnmappingtable where fdn like '0=#1#/14=#S0058-3#/17=#S0058-3#/18=#1#/780=#5#%')))order by f1.id asc
This query is taking more than 4 seconds to get the results in a system where the DB is running for more than 1 month.
The same query is taking very few milliseconds (50-100ms) in a system where the DB is freshly installed and the data in the tables are same in both the systems.
Kindly advice what is going wrong??

Sql select query problem

hi friends,
i've a view called "risk_efforts" with fields user_id,user_name,wknd_dt,week_day,prod_efforts,unprod_efforts.
Name Type
ROW_ID NUMBER
USER_ID VARCHAR2(14)
USER_NAME VARCHAR2(50)
WKND_DT VARCHAR2(8)
WEEK_DAY VARCHAR2(250)
PROD_EFFORTS NUMBER
UNPROD_EFFORTS NUMBER
data is like this:
when there is some data in prod_efforts, unprod_efforts will be null
when there is some data in unprod_efforts, prod_efforts will be null
for example:
USER_ID     USER_NAME     WKND_DT     WEEK_DAY     PROD_EFFORTS     UNPROD_EFFORTS
G666999     GTest     20100403     TUE     null 3
G666999     GTest     20100403     TUE     14     null
now i want to combine these 2 rows into 1 row i.e o/p should be like this
USER_ID     USER_NAME     WKND_DT     WEEK_DAY     PROD_EFFORTS     UNPROD_EFFORTS
G666999     GTest     20100403     TUE     14 3
i've tried all combinations but couldn't get the query. Please help me with the exact SQL select query.
thanks,
Girish

Welcome to the forum.
First read this:
Urgency in online postings
Secondly, it's always helpful to provide the following:
1. Oracle version (SELECT * FROM V$VERSION)
2. Sample data in the form of CREATE / INSERT statements.
3. Expected output
4. Explanation of expected output (A.K.A. "business logic")
5. Use \ tags for #2 and #3. See FAQ (Link on top right side) for details.
You have provided #3 and #4. However with no usable form of sample data forum members will often not respond as quickly as they could if you provided #2.
I'm just wagering a guess here but what about this:SELECT ROW_ID
, USER_ID
, WKND_DT
, WEEK_DAY
, MAX(PROD_EFFORTS) AS PROD_EFFORTS
, MAX(UNPROD_EFFORTS) AS UNPROD_EFFORTS
FROM RISK_EFFORTS
GROUP BY ROW_ID
, USER_ID
, WKND_DT
, WEEK_DAY

How to capture all the rows returned from a sql select query in CPO

Hi,
I am executing an sql select query which returns multiple rows. I need to capture the values of each row to specific variables. How do I proceed.
Thanks,
Swati

The select activities ("Select from Oracle," Select from SQL Server," etc.) against database already return tables. Use one of the database adapters to do your select, and it will already be in a table form. Just put your query in the select and identify the columns in your result table. The online help or the database adapter guides in the product documentation can help.

Reg: SQL select Query in BPEL process flow


Hi,
I am suppose to execute a SQL select query (in BPEL Process flow) as mention below in JDeveloper using Database adapter.


SELECT LENGTH, WIDTH, HEIGHT, WEIGHT,


LENGTH*WIDTH* HEIGHT AS ITEM_CUBE


FROM CUBE


WHERE ITEM= <xyz>


AND OBJECT= (SELECT CASE_NAME FROM CUBE_SUPPLIER WHERE ITEM=<xyz> AND SUPP_IND = ‘Y')
Now my question is:
1. What does this "*" refer to in the query and how can I retrieve the value of LENGTH*WIDTH* HEIGHT from the query where LENGTH,WIDTH and HEIGHT are the individual field in the table.
2.What does this " AS" refer to? If " ITEM_CUBE " is the alies for the table name "ITEM" to retrieve the value, then query shoud be evaluated as


SELECT LENGTH, WIDTH, HEIGHT, WEIGHT,


LENGTH*WIDTH* HEIGHT AS ITEM_CUBE


FROM CUBE


WHERE ITEM_CUBE.ITEM= <xyz>


AND ITEM_CUBE.OBJECT= (SELECT CASE_NAME FROM CUBE_SUPPLIER WHERE ITEM=<xyz> AND SUPP_IND = ‘Y')
Is my assumption correct?
Please suggest asap.
Thanks...




Hi
Thank for your reply!
I have a nested select query which performs on two different table as shown below:

SELECT LENGTH, WIDTH, HEIGHT, WEIGHT,


LENGTH*WIDTH* HEIGHT AS ITEM_CUBE


FROM CUBE


WHERE ITEM= <abc>


AND OBJECT= (SELECT NAME FROM SUPPLIER WHERE ITEM=<Item> AND SUPP_IND = ‘Y')
I am using DB adapter of Oracle JDeveloper in BPEL process flow, where I can able to select only one master table in DB adapter say SUPPLIER and its attributes at a time.But as per my requirment I need to select both the table (CUBE and SUPPLIER) in a single adapter to execute my query.
It can be achievable by using two DB adapter , One to execute the nested query and another to execute the main qyery considering value of nested query as a parameter.But I want to achieve it by using a single one.
Am I correct with my concept?
Please suggest how to get it ?

From SharePoint Content Database, Using SQL-Server Query how to fetch the 'Document GUID' based on 'Content Type'

I want to get all the documents based on content type using SQL Server Query. I know that, querying the content database without using API is not advisable, but still i want to perform this action through SQL Server Query. Can someone assist ?

You're right, it's not advisable, may result in corruption of your databases and might impact performance and stability. But assuming you're happy to do that then it is possible.
Before you go down that route, have you considered using something more safe like PowerShell? I've seen a script exactly like the one you describe and it would take far less time to do it through PS than it would through SQL.

sql server query to rearrange the rows after inserting the rows in a table

You want to re-arrange the data physically?!!! Why? I believe its something impossible other than having a clustered key(there could be some strange ways of doing it) and a thing that should not worry about. Always there is a ORDER BY CLAUSE to order your
data while retrieving

Sql developer query window corrupting on scroll

Hi there
I have a weird error - when I scroll in my SQL developer query window (tab) the text corrupts and only comes back if I click in the window somewhere or save. Has anyone else seen this? I'm on version 1.5.5 and don't really want to upgrade to the latest as I don't like the new layout (no dbmsoutput etc in the results window)
Cheers, Kate

sorted it by adding a line AddVMOption -Dsun.java2d.noddraw=true to the sqldeveloper.conf file, as per thread SQL Editor not refreshing after scroll on Windows Vista

Using SQL in Query in 3.0.0

Marc,
Calling pm.flush() explicitly doesn't help. Calling
query.setIgnoreCache(true) does work, so that's good.
I even get the correct number of rows back in the Collection. Unfortunately
every item in the Collection is null. I definitely did a
query.setClass(DSChannelValueImpl.class) and it is enhanced properly,
because that's how the table got populated earlier in the test. I am doing a
SELECT *, so the class indicator and pk should be there. I'm assuming it
doesn't mind me aliasing the FROM table name, since I need to disambiguate
it to do a join (below).

Ben-
I've made a bug report for this:

In the meantime, a nicer workaround will probably be to just call
setIgnoreCache(true) on the Query.

Save layout of queries in SQL Developer query builder?

Sometimes queries are very complex and moving tables around in the graphical view is really helpfull to better understand them.
Unfortunately this layout does not get saved with "save" (because this is a simple text file).
Once upon there was a query builder (included with designer 2000 and later vom 1991 to 1998) that had a proprietary format (.brw) to just do that: Save a query including layout.
Any chance to save the layout of SQL Developer query builder queries?

I dont think there is any way to save the layout for the query, you can request an enhancement on the Exchange for this http://sqldeveloper.oracle.com/
But if you only need to restore the query you are working with later, or move it to another workstation and continue editing using the query builder, you only need the SQL code generated; when you paste it in an opened worksheet (on the same database or even a clone with the same structure) the query builder is able to resume working just fine with default positioning for the table objects.
If you hand edit the query and insert some SQL manually then the query builder may stop working for particularly complex statements, in this case it will warn you and disable itself.

Adding columns in a open sql select query

Hi Everyone,
I would like to add the values of n columns of a table and place them in one column, how can i achieve this in open sql.
In oracle native sql the query will look like this:
Select col1 + col2 + col3 AS col
from tab1;
On a similar grounds, i would like to concatenate the contents of n columns into one column. The oracle native sql will look like this:
select col1 || col2 || col3
from tab1;
How can I do this in Open SQL.
Thanks in advance.
Prabhu.

Hi Prabhu,
I'm afraid what you're trying to do is not possible using the Open SQL. You will have to get the data from all the three columns into an internal table and then write your own logic to accomplish the same.
data : begin of itab occurs 0,
 col1 type i,
 col2 type i,
 col3 type i,
 col4 type i,
 end of itab.
field-symbols: <fs_itab> like line of itab.
SELECT COL1
 COL2
 COL3
INTO TABLE ITAB.
LOOP AT ITAB assigning <fs_itab>.
<fs_itab>-col4 = <fs_itab>-col1 + <fs_itab>-col2 + <fs_itab>-col3.
ENDLOOP.

Anand Mandalika.
