Use of FIELD in Attribute SQL Query

Hi folks,
Back in 7.1 you could use %FIELD.[attributename]% in a sql query defining an identity store attribute's values.
Does anyone know if this functionality was lost in 7.2? Can't seem to get it to work.
Thanks,
Matt

Hi Moritz,
did you consider that note:
Note: Both
fields must be
defined as "Single value" with presentation type "Single select"?
It does not work as soon as you use other storage or presentation types.

Use realational operators in an SQL query??????

does any one knows how to use realational operators in an SQL query??????
i wud like to do something like
select decode(2<3,sysdate,sydate +1) from dual
but i know decode does not supports relational operators......
thanx and Regards
amyt

You can use a CASE statement which does support relational operators, or if you must use DECODE, then you can use something like:
SELECT DECODE(SIGN(2 - 3),-1,sysdate,sysdate - 1)
FROM dual;The SIGN function returns -1 if the expression is < 0, 1 if the expression is > 0 and 0 if the expression is 0. This works for numeric comparisions. You can use the GREATEST or LEAST functions in a similar fashion for character comparisions.

We never saw your procedure, but maybe you could wrap it in a function
SQL> create or replace procedure get_members(in_something IN number, out_members OUT sys_refcursor)
is
begin
open out_members for
    'select level member_id from dual connect by level <= :num' using in_something;

Creating an Hour field in an SQL Query CUIC v10.0

I am trying to create a report that shows the calls offered etc by Hour, instead of by half hour or 15 minutes which comes with the usual DateTime (interval) query.
I am using DATEPART (Hour, DateTime) As Hour and whilst this is giving me the hour number in the new column, I an showing 2 rows per hour as per the half hour interval.
I have included it in the Group By and this makes no difference, Whilst I can group them by hour and that would in effect solve the issue, I then loos the Date Field!
Ideally what I would like to see in 1 column is
Call Type 1    4/2/15 10:00 AM
                      4/2/15 11:00 AM
                      4/2/25 12:00 AM
etc.....
Instead what I have is
Call Type 1    4/2/15 10:00 AM        10
                      4/2/15 10:30 AM         10
                      4/2/25 11:00 AM         11
                     4/2/25 11:30AM          11
etc...
If there is anyone out there that can help I would be most grateful
Thanks Sarah

Sarah,
You will need to make sure you remove "DateTime" from your GROUP BY clause, and from the SELECT statement.
Instead of using DATEPART, I would use something like:
DateTimeHour = DATEADD(h,DATEDIFF(h,0,DateTime),0)
The above will give you a full DateTime value, rounded down to the nearest hour. Don't forget to include it in the GROUP BY (and probably SORT BY).
You can add "DateTime" back as Filter Field in CUIC after you do the initial Create Fields step (look on the Fields page). Filtering on DateTime instead of DATEADD(h,DATEDIFF(h,0,DateTime),0) should make for a more efficient SQL query.

Using System Variables in a SQL Query

Hi!
I´m new to Oracle and SQL so i don´t know very much about it.
There is miy Problem:
Is there a way to Use the System Variable %USERNAME% in an SQL Query?
I tried .... where table.shorttag = '%USERNAME%' ;
but this doesnt work.
Is Oracle able to handle Systemvariables? Or is there another way to use the current Windows User in an SQL Query.
It is very Important to use the current Windows user and not the Oracle user.
Thank you,
Mfg

Are you looking for something like this ?
SQL> SELECT sys_context('USERENV', 'OS_USER') FROM dual;
SYS_CONTEXT('USERENV','OS_USER
SAUBBANE\IBM
SQL> SELECT sys_context('USERENV', 'TERMINAL') FROM dual;
SYS_CONTEXT('USERENV','TERMINA
SAUBBANEAlso you can look at the dbms_application_info package.

Using IN keyword in an sql query in a view criteria

Hi,
I am using jdev 11.1.1.1.0 and defined an lov query/viewobject as
select a, b, c from myTable
I now need to predefine filtering for lov search functionality and need something like the following
select a, B, c from myTable where B in ('X','Y')
I could not find a way to do it (i.e. specify the use of IN Keyword) in the Create View Criteria dialog box. I tried to define OR, but is that the best way to redefine IN as i have a long list (the above is just an example)
(( ( (UPPER(B_FLAG) = UPPER('X') ) ) OR ( (UPPER(DISPLAY_FLAG) = UPPER('Y') ) ) ))

If you know how many variables are in your "in" You can just write this in the sql query of your VO:

Using Multi Select List in SQL Query

Hi all,
I am trying to using a Multi Select list for filtering of a report. I have :P2_RISK_SEVERITY which has has the possibility of values Very Low:Low:Medium:High:Very High. How do I use this Multi Select in the where section of a SQL query?
I need to say something along the lines of:
Select RISK_SEVERITY from TBL_RMD_RISKS where RISK_SEVERITY = (one of the options selected in the multi select)
Thanks for the help.

Hi there,
The above suggestion will work perfectly as long as the table you're querying is relatively small, but keep in mind that applying the INSTR to the left side of the WHERE clause will always result in a full table scan. This means that if your table is large and RISK_SEVERITY is indexed, the index will never be used. Here is another approach (credit to AskTom) that converts your colon-delimited string of selected values to a list that can be used in an "IN(...)" clause, which will use an index on RISK_SEVERITY as long as the optimizer otherwise deems it appropriate:
-- creates a type to hold a list of varchars
CREATE OR REPLACE TYPE vc2_list_type as table of varchar2(4000);
-- converts a colon-delimited string of values to a list of varchars
CREATE OR REPLACE FUNCTION vc2_list(p_string in varchar2)
   return vc2_list_type is
   l_string       long default p_string || ':';
   l_data         vc2_list_type := vc2_list_type();
   n              pls_integer;
begin
   loop
      exit when l_string is null;
      n := instr(l_string, ':');
      l_data.extend;
      l_data(l_data.count) := ltrim(rtrim(substr(l_string, 1, n - 1)));
      l_string := substr(l_string, n + 1);
   end loop;
   return l_data;
end vc2_list;
-- your WHERE clause
where risk_severity in(
         select *
           from the(select cast(vc2_list(:P2_RISK_SEVERITY) as vc2_list_type)
                      from dual))

Sorting of Date field in the SQL Query useing ORDER BY

The query is having a date field and I have to sort the query results using ORDER By for the Date field. The query is giving exact results in the SQL PLus interface.
When I am getting this results in the GUI where servlets are being used an Exception is coming as not supported RefreshRow method.
If anyone has faced this problem and have got the solutions please let me know.

Using a URL parameter in SQL Query

Newbie question...
I have been developing a dashboard application, and I have been using input bind variables in the SQL. That all works fine.
What I would like to do is to have a user go to a page via a URL with paramaters like this:
http://atlas:7777/pls/apex/f?p=112:1:9191429456552868531:::::P1_ITM_CD_PASSED:JMINV
where P1_ITM_CD_PASSED is the parameter and JMINV is the value.
Then, I want the SQL to execute using that:
select *
from itm
where itm_cd = ': P1_ITM_CD_PASSED'
I tried testing this on a page. Set up a report region, but it appears that the paramater is not making it to the SQL. "No Records Found".
Is there a simple example out there that anyone knows of? Maybe I am missing an item, computation, process, etc. to be able to utilize the paramater?
Thanks in advance

varad
Thanks for the reply. I did try that, and same results. It seems that the parameter is not getting bound to the variable, or it's getting flushed after the page loads. Here is what debug shows me:
P1_TEST
0.08: show report
0.10: determine column headings
0.10: activate sort
0.10: parse query as: CUSTOM
*0.11: binding: ":P1_ITM_CD_PASSED"="P1_ITM_CD_PASSED" value=""*
0.11: print column headings
0.11: rows loop: 15 row(s)
no data found

Use the results of an SQL query to create another query

I am working on a bidding/allocation system using C# and MySQL, and I am currently having difficulty implementing the “post-allocation” mechanics of the system. Let me explain how it works, before introducing the code:
When the bids are made on the system, they all have the position 0, so the first thing the system does is order them according to priority.
(bid table)
In this case, 5 bidders are interested in what is in plot 15, but we have not assigned them a position yet.
(bid table)
The system then organises the bids according to the order in which they are going to processed.
The bids are then allocated, but unfortunately there are only 3 spaces in plot 15 that can be allocated. As a result, we use the priority listing to determine which bidder gets what.
(booking table)
At this stage, I can say that I am stuck, there are two things that I want to do, both of which involve reusing the results of the query at step 2.
(bid table)
The bidders that have their job allocated should see: their bid.status updated
from Queued to Allocated,
the bid.position should
be set to 0,
and their job_id should
be set to the booking they have been allocated (i.e. booking.id).
The bidders that have not had their jobs allocated should see: their bid.status remain
as Queued, and their bid.position should
be set to 0 in
preparation for the method to run again
The difficulty I am having is in stage 3, how do I determine which jobs have been allocated and which ones have not, and then run the necessary SQL queries in order to make the updates?
My code so far is as follows:
// STEP 1a - SELECT BIDS
string query =
"SELECT t1.operator_id, t1.datetime, t1.plot_id, t1.position, t2.market_access FROM bid t1 " +
"JOIN operator t2 ON t1.operator_id = t2.id WHERE t1.status='Queued' AND t1.postcode=@postcode " +
"ORDER BY t2.market_access ASC, t1.datetime ASC";
var bidList = new List<BidList>();
var cmd = new MySqlCommand(query, _connection);
cmd.Parameters.AddWithValue(("@postcode"), _plot);
MySqlDataReader dataReader = cmd.ExecuteReader();
while (dataReader.Read())
var item = new BidList
OperatorId = dataReader["operator_id"] + "",
PlotId = dataReader["plot_id"] + "",
Position = dataReader["position"] + "",
Datetime = dataReader["datetime"] + "",
MarketAccess = dataReader["market_access"] + "",
bidList.Add(item);
dataReader.Close();
// STEP 1b - SET PRIORITIES
for (var i = 0; i < bidList.Count; i++)
var position = i + 1;
bidList[i].Position = position.ToString();
query = "UPDATE bid SET position=@position WHERE status='Queued' AND postcode=@postcode AND operator_id=@operator_id;";
cmd = new MySqlCommand(query, _connection);
cmd.Parameters.AddWithValue(("@position"), position);
cmd.Parameters.AddWithValue(("@postcode"), _plot);
cmd.Parameters.AddWithValue(("@operator_id"), bidList[i].OperatorId);
cmd.ExecuteNonQuery();
dataReader.Close();
// STEP 2 - ALLOCATE JOBS ACCORDING TO PRIORITY
foreach (var t in bidList)
query = "SELECT operator_id, plot_id, status FROM booking " +
"WHERE status='open' AND postcode=@postcode AND operator_id='0'" +
"ORDER BY datetime ASC;" +
"UPDATE booking SET operator_id=@operator_id, status='Allocated' " +
"WHERE (plot_id=@plot_id AND operator_id='0' AND status='Open') LIMIT 1;";
cmd = new MySqlCommand(query, _connection);
cmd.Parameters.AddWithValue(("@operator_id"), t.OperatorId);
cmd.Parameters.AddWithValue(("@postcode"), _plot);
cmd.Parameters.AddWithValue(("@plot_id"), t.PlotId);
cmd.ExecuteNonQuery();
dataReader.Close();
// STEP 3
CloseConnection();

I can't tell. When modifying row(s) you have to be able to uniquely be able to identify the row(s) in the database you want to modify. That is why I recommended the other day to use DataAdapter instead of the DataReader. You can with the
reader, but you need to unique identify the rows.
I can't tell from the limited amount of data you posted if in table 2 that there is only one row with the same operator id and plot id. It looks like in table 2 the 'id' number is unique. When working with a database with multiple tables you
need to be able to link tables together with primary keys (columns wit unique values). If the database isn't designed properly then it is impossible to do some operations. So you always have to make sure you design a database properly.
jdweng
When you say table 2 are you referring to the bid or booking table?
Here is the table structure for the bid table
Here is the table structure for the booking table
Hope it helps makes things clearer!

How to use the result of a sql query for a max () function

Hi
I wrote a query on which i wrote
"select max(id) from users "
how can i use the returned value.
if i made the var name ="userid"
can it be userid.rows[0] or what.
thnx for any help

Hi!
The result of this query will be the max ID of users' IDs.
Let say we have:
String sql="select max(users.id) from users";
Statement st = ctx.conn.createStatement();
ResultSet rs = st.executeQuery(sql);
rs.next();
So you can get the max Id in the following way:
int maxId=rs.getInt("id");

Using CASE in a dynamic sql query

Hi,
I want to create a dynamic query using the CASE statement to replace the below 2 SQL statements:
+++++
select 'create or replace synonym '|| SYNONYM_NAME || ' for '||TABLE_OWNER||'.'||TABLE_NAME||'@'||SUBSTR(db_link,1,30)||' ;' FROM USER_SYNONYMS where db_link is not null;
select 'create or replace synonym '|| SYNONYM_NAME || ' for '||TABLE_OWNER||'.'||TABLE_NAME||' ;' FROM USER_SYNONYMS where db_link is null;
+++++
So that i have a single select query which will give the create synonym statements for all with/without db links
Using the CASE statement example like given below :
SELECT
FirstName, LastName,
Salary, DOB,
CASE Gender
WHEN 'M' THEN 'Male'
WHEN 'F' THEN 'Female'
END
FROM Employees
I am not getting how to write this CASE statement. Can someone guide me here?
Thanks,
