I am using a choice list in dashboard prompt with default value:"All Column values" and set to a presentation variable:"presvar
In BIP 11G data model,in where clause i am writing it as:
where(tablename.colname in (:presvar))
This is working only when i select single value in prompt ,if i select multi values in dashboard prompt it is not fetching me exact results.
Kindly help if someone has faced the situation
Version:11.1.6.2
The following will work for single values, multiple values, and a null value:
WHERE (tablename.colname IN (:presvar) OR 'DUMMY' IN (:presvar || 'DUMMY'))

I have an interactive report in my application. When I click the 'delete' icon, I want to delete information about the user I selected. Is there a way to get the value from the 'Facility Manager' column so I can use that value in a select statement to perform the delete statement.
I've tried to do it by using the ROW_ID variable (:selected_rowid) but this didn't work.
+ Interactive Report Image
+ Set Value statement
The column value is referenced by hashes, e.g. #STUDENT_ID#.
Have a look at what Jackie McIlroy wrote, "Delete a Row of a Report with a Dynamic Action" (https://jackiemcilroy.blogspot.com/2018/03/delete-row-of-report-with-dynamic-action.html) . She describes the process in details, with a lot of screenshots.
If I were you, I'd do one of the following:
use an interactive report with a form (and navigate to the form in order to delete a row)
if it has to be a tabular layout, I'd try
the old tabular form
the new interactive grid
I don't think I'd remove rows from the interactive report (but OK, that's just me, and my ideas usually aren't too smart).
I use Crystal report 2011 to create report from with data from Oracle database. I have a Allow multi values parameter name userid (userid is string).
I want to query
Select ... from table where userid in {?userid};
I try {?userid}, ({?userid}), '{?userid}' ... but it's not working.
what should I do?
Put the cursor on the place where you want it, and double click on the parameter.
We have a legacy application we cannot modify that connects to Oracle 11g and at some point runs a query and returns a result. The application however is using the "generated" column name from Oracle to read the result.
Consider the following query:
select nvl(1,0.0) from DUAL;
As this query does not specify an alias, the generated column name would be "nvl(1,0.0)"
However on another server the generated column name is "nvl(1,0)" (notice 0 and not 0.0) and the application fails.
Is there a configuration that can be changed for Oracle? I've searched for formatting and locale configurations and they are equal on both servers.
Any help would be appreciated
It turns out there's a parameter called cursor_sharing that was set to FORCE instead of EXACT
select nvl(1,0.0) from DUAL;
The query above returns the following depending on the value of the parameter:
FORCE=NVL(1,0)
EXACT=NVL(1,0.0)
I'm having one of those throw the computer out the window days.
I am working on a problem involving Crystal Reports (Version 10) and an Oracle Database (11g).
I am taking a view from the database that returns a string (varcahr2(50)) which is actually a number, when a basic SELECT * query is run on this view I get the number back in the format 000000000000100.00.
When this view is then used in Crystal Reports I can view the field data, but I can't sum the data as it is not a number.
I began, by attempting to using ToNumber on the field, to which Crystal's response was that the string was not numeric text. Ok fair enough, I went back to the view and ran TO_NUMBER, when this was then used in crystal it did not return any results. I also attempted to run TO_CHAR on the view so that I could hopefully import the field as text and then perform a ToNumber, yet the same as with the TO_NUMBER no records were displayed.
I've started new reports, I've started new views. No avail.
This seems to have something to do with how I am retrieving the data for the view.
In simplistic terms I'm pulling data from a table looking at two fields a Foreign Key and a Value field.
SELECT PRIMARY_KEY,
NVL(MAX(DECODE(FOREIGN_KEY, FOREIGN_KEY_OF_VALUE_I_NEED, VALUE_FIELD)), 0)
FROM MY_TABLE
GROUP BY PRIMARY_KEY
When I attempted to put modify the result using TO_NUMBER or TO_CHAR I have used it around the VALUE_FIELD itself and the entire expression, wither way works when the run in a SQL statement. However any TO_NUMBER or TO_CHAR modification to the statement returns no results in Crystal Reports when the view is used.
This whole problem smacks of something that is a tick box or equivalent that I have overlooked.
Any suggestions of how to solve this issue or where I could go to look for an answer would be greatly appreciated.
I ran this query in SQL Developer:
SELECT xxx, to_number(xxx) yyy
FROM (
SELECT '000000000000100.00' XXX FROM DUAL
)
Which resulted in:
XXX YYY
000000000000100.00 100
If your field is truly numeric, you could create a SQL Expression field to do the conversion:
-- {%NUMBER_FIELD}
TO_NUMBER(TABLE.VALUE_FIELD)
This turned out to be an issue with how Crystal Reports deals with queries from a database. All I needed to do was contain my SQL statement within another Select Statement and on this instance of the column apply the TO_NUMBER so that Crystal Reports would recognize the column values as numbers.
Hopefully this helps someone out, as this was a terrible waste of an afternoon.
I am using the BIRT report writer, and I have multiple tables with the same data structure. In my report design, I want to select the table my query uses as a report parameter (as part of a mysql query in the data set) -- but I can't figure it out.
When I create the data set, it's great that I can use parameters in the form of SELECT * FROM WHERE ?, and set these to report parameters, but I get an error if I set the ? to the table, such as:
SELECT * FROM ? WHERE 1
Is there another way I can do this? As it's java, I assume the syntax follows that of a PreparedStatement. In BIRT 2.5 there is a property binding option under the data set dialog... and I've tried setting my query as: "SELECT * FROM "+params["DataTable"].value+" WHERE 1", but that was also results in an error.
I just answered this same question over at BIRT Exchange: http://www.birt-exchange.org/forum/designing-birt-reports/19097-set-query-table-using-report-parameter.html#post62590
I should note that the queries MUST return the same fields & data types after you modify them. I only note this because of your statement above that the table structure varies "a bit". It is perfectly safe to modify the FROM or WHERE clauses in a BIRT query, but you cannot modify the actual SELECT construct.
