iReports Grouping Bug - Multiple Occurrences? - expression

I'm am getting irritated with iReports. Problem is that I have a data set returning data for multiple customers and I want to use the "Group Expression" against the customer ID and have the report lay out the Detail Tabs per customer.
I'm finding that, seeming randomly, where there is more that one data row for a customer iReports will generate two or more groupings (Sometimes it does what I expect and group all the customer data together), the field IDing the customer is the same and doesn't change.
Has anyone seen this before? To be honest I can't believe it is actually a bug, but something I've missed. Just much searching as yet to find a suitable result.

I think this is a data sorting problem.
The quote from iReport Ultimate Guide:
JasperReports groups records by evaluating the group expression. Every
time the expression's value changes, a new group instance is created.
The engine does not perform any record sorting (if not explicitly
requested), so when we define groups we should always take care of the
records sorting. That is, if we want to group a set of addresses by
country, the records we select for the report should already by
ordered by country. It is simple to sort data when using an SQL query
by using the ORDER BY clause. When this is not possible (that is, when
obtaining the records from an XML document), we can request that
JasperReports sort the data for us. This can be done using the sort
options available in the query window
You can sort data in these ways:
in case using of Database jdbc connection datasource type you can add ORDER BY customerId clause to the report's query, where customerId - column name of field with customer id
in case using of File csv connection or something like this you can organize data sorting by adding sortField property for field to the report's template (jrxml file):
<jasperReport ...>
...
<field name="customerId" class="java.lang.String"/>
<sortField name="customerId"/>

SQL Statement has ORDER BY?
iReport group is grouped by customer_id?

BIRT suppress multiple duplicate columns

I am working on a BIRT report. Its records are grouped on the basis of the status column. I was looking for an option in the Eclipse BIRT tool by which I can hide combinations of multiple columns in a row which are repeating. I have attached screenshots for both the current report and the expected report structure.
I tried the "suppress duplicate" option but that is limited to a single column. I am not able to apply this on multiple columns together. I couldn't figure out any other option. Please suggest any solution in the tool or do I need to change my query to return the result in the expected format?
Actual Result:
Expected Result:
There are three obvious ways to hide duplicate values.
All of these require you to configure this per column (BTW I don't understand why you consider this to be a problem).
As you already did: Use "suppress duplicates" at the column level.
Add more groups to your table after the existing group.
E.g. one group for the first column (whatever that is).
Then you can choose "Drop" "detail" in the properties of the corresponding group header cell. It's a bit difficult to get the layout right this way.
In your data set, if it's SQL, you can use a little construnct with CASE and the LAG analytic function to compare the column value to that of the previous row, and if they are equal, return NULL instead (pure SQL solution).

Laravel - find offset of record in mysql results

I have a MySQL table of records with several fields.
These records are shown and updated live in the browser. They are displayed in an order choosen by the user, with optional filters also choosen by the user.
Sometimes a change is made to one of the records, and it may affect the order for a given user.
In order to position the message correctly in the list, I need to find where its new offset falls after the change to the record. Basically, I need to get the "id" for the record that now comes before it in the MySQL results, so that I can use Javascript on the client side to reposition the record on the screen.
In raw SQL, I'd do something like this:
SET #rank=0;
SELECT rank
FROM
(SELECT #rank:=#rank+1 AS rank,
subQuery.id AS innerQuery,
FROM ...{rest of custom query here}... as subQuery)
AS outerQuery WHERE outerQuery.innerQuery={ID TO FIND};
Then I can just subtract 1 from the resulting rank, and find the ID of the question that comes before the record in question.
Is this kind of query possible with Laravel's query builder? Or is there a better strategy than what I've come up with here to accomplish the same task?
EDIT: There are a lot of records. So if possible I'd like to avoid loading all the records into memory to find the offset of the record. They are originally loaded on the screen in an "infinite scroll" type method, since it would be too much to load all of them at once.

Crystal Reports - Sorting two different date fields chronologically

I've got two date fields from two tables and I'm trying to show receipts of POs in line with work order consumption sorted chronologically.
Is there any way to sort two date fields together?
For instance:
1/1/14 work order date
1/5/14 work order date
1/7/14 PO receipt date
1/9/14 work order date
1/20/14 work order date
The two fields are 'duedate' from table 'porel' and 'reqdate' from table 'jobmtl'
Usually the simplest solution in such cases is to perform the ordering at the server side (e.g. using SQL Server stored procedure, Access query, etc.), and then use the stored procedure or query as the source for the data.
An alternative that I read about is to create global variables in the report, assign your dates values to these variables using 'WhilePrintingRecords;' in formula fields, and using these variables that then does the actual reporting for you.
Slightly complicated.
Another solution which I am not sure if applies to you is :
Click on the main menu > Report > Record Sort Expert
Select your date field in the box on the left and add it to the box on the right
Check the Ascending checkbox and click Ok
Let us know how it goes.
you should create a formula saying
if (table1.duedate = null) then
{table2.duedate}
else
{table1.duedate}
Then sort on this formula. Check the syntax yourself.

Filtering Quotes by InventTable

I'm trying to build a report in AX 2009 (SP1, currently rollup 6) with a primary data source of the SalesQuotationLine table. Due to how our inventory is structured, I need to apply a filter that shows only certain categories of items (in this case, non-service items as defined in the InventTable). However, it seems that there is a problem in the link between the SalesQuotationLine and InventTable such that only two specific items will ever display.
We have tested this against the Sales Quotation Details screen as well, with the same results. Executing a query such as this:
...will only show quotes that have one of the specific items mentioned earlier. If we change the Item Type to something else (for example to Item), the result is an empty set. We are also getting this issue on one of our secondary test servers, which for all intents is a fresh install.
There doesn't seem to be any issues with the data mapping from the one table to the other, and we are not experiencing this issue with any other table set. Is this a real issue, or am I just missing something?
After analyzing the results from a SQL Profile run during the execution of the query, it seems the issue was a system bug. When selecting a table to join to the SalesQuotationLines, you have two options: 'Items' and 'Items (Item Number)'. Regardless of which table you select the query executes with, it joins the InventTable with the relation "SalesQuotationLines.ProjTransCode = InventTable.ItemId".
After comparing the table to other layers in the system, I found the following block of code removed from the createLine method (in the SYP layer):
if (this.ProjTransType == QuotationProjTransType::Item)
{
this.ProjTransCode = this.ItemId;
}
Since the ProjTransCode is no longer being populated, the join does not work except on certain quote lines that do have the ProjTransCode populated.
In addition, there is no directly defined relation to the InventTable - the link is only maintained via an Extended Data Type that is used on the SalesQuotationLine.ItemId field. Adding this relation in manually solved the problem.

VB6 and data-bound MSHFlexGrid, moving and populating columns

I'm working on a VB6 program that connects to a SQL Server 2008 R2 database. In the past I have always used the MSFlexGrid control and populated it manually. Now, however, the guy who is paying me for this wants me to use data-bound grids instead, which forces me to use the MSHFlexGrid control because I'm using ADO and not DAO. So, I have two questions...
First, how would I move a column in a MSHFlexGrid? For example, if I wanted the third column to appear as the sixth column in the grid, is there a simple single line of code that would do that?
Second, believe it or not, I've never had to do anything in a grid other than display the data, as is, from a recordset. Now, however, I have a recordset with some fields that contain just ID numbers that refer to records in other files - for example, a field containing an ID number referring to a record in the Customers table, instead of the field containing the customer's name. What is the easiest way to, instead of having a column showing customer ID numbers from the recordset, having that column show customer names? I thought I read somewhere that there's a way to embed a sql command in a MSHFlexGrid column, but if there is I wouldn't know how to do it. Is this possible, or is there a simpler way to do it?
TIA,
Kevin
The column order would typically be handled by your SELECT statement.
Say you have a Pies table that has a FruitID foreign key related to the FruitID in a Fruits table:
SELECT PieID AS ID, Pie, Fruit FROM Pies LEFT OUTER JOIN Fruits
ON Pies.FruitID = Fruits.FruitID
This returns 3 items: ID, Pie, and Fruit in that order.
Moving columns after the query/display operation is rarely used, but yes ColPosition can be used for that.
Wow! VB6.... Back to the future! :-)
You can move Columns using the ColPosition Property.
This article shows how you could setup the grid to display hierarchical data.
If you just want to display the customer name on the same line as the main data then that is doable as well by just creating the proper SQL for your data source. For that matter you can control the column order the same way as well.
Now, how about considering upgrading to .Net? Just kidding..... No, I'm not. OK. I am, maybe. :-)
