I am currently dynamically generating labels ids on my ASP site based on the date of the month.
E.g. labelSunday1.ID = "01/07/12"
I am also pulling data down from SQL Server, and storing various values in strings.
E.g. Date = resultDate, stock = resultStock
However, I want to do a find on the page, looking for any Label ID that matches the result of the query, and then display the number of stock in the labels text.
Is there anyway I can search the entire page to see if a label ID matches the resultDate string? I would rather do this search somewhat dynamically, as in the future I hope to dynamically generate many labels on the page.
I was thinking along the lines of:
IF Me.Label.ID = resultDate then
me.label.text = resultStock
but that doesn't work :C
Thanks in advance
The answer was to use "01_01_2013" as an Identifier.

I have a HTML input box that I want to be able to submit URLs into. Only problem is that when I go to submit multiple urls, they are inserted into 1 row in the SQLite database in one big blob.
"http://google.com/http://stack.com/http://aol.com/"
When I want them to be:
Row 1: http://google.com/
Row 2: http://stack.com/
Row 3: http://aol.com/
Essentially, for every URL in the input box to be put into it's own individual row.
How can I achieve this?
This can be done in two steps.
Split the URL(consider it as a string) on the basis of a token ('/').
Then loop over the split string (as per example 3) and save it in DB.
Here is the example code.
var str = 'http://google.com/http://stack.com/http://aol.com/';
var str_array = str.split('/');
I am having a field named rpc in my elasticsearch database and I am displaying it using Kibana. When I search in search bar of kibana like:
rpc:*
It display all the values of rpc field but I want to have only those value to be displayed which are unique.
I have been playing around with Kibana4 since a couple of weeks now. I find it intuitive and simple and the experience has been great till now. Following your question, I tried getting unique results via a Data Table visualization. Why? Because I personally find it easier to understand. Following are the steps:
1. Get unique count
Create the visualization (Visualize -> Data Table). First lets get
the count of how many unique entries we have for a particular field
(We will use this in the later part for verification). I'm using
clientip.raw but as I see, it will work just fine with any friendly
field name too.
2. Set the aggregation right
Set you aggregation back to count and have a Split Rows as follows. Not doing this will give you count 1 for each field value (since it is looking for unique counts) when you populate the table. Noteworthy part is setting the Top field to 0. Because Kibana won't let you enter anything else than a digit (Obviously!). This was the tricky part. Hit Apply and you'll get the results. Unique field values and the count of each of them.
3. Verification:
Going to the last page of the table, we see there are exactly 543 results. This is how I know it works.
What Next?
You save this visualization and add it to a Dashboard. There you can always check the request, query, response and other stats.
Just an addition to the above mathakoot answer.
For the user of newer version (which do not allow bucket size of 0 anymore) just set a value greater than the maximum number of result
And report the value in the Options>Per Page field
I am using Kibana 6 so the UI looks a bit different than the older answers here.
Here is what worked for me
Create a visualization from your query, I used a line graph type (don't think it matters)
Under Data, set metrics aggregation = "Unique Count" and set field to your field.
Set x-axis aggregation = "Terms" and set field to your field.
Set Size > your number of records
Under Metrics and Axes, disable drawing of the graph, circles, and labels (this really helps the UI not lag)
Run query and then click "Inspect" and download CSV
Data
Metrics & Axes
I wanted to achieve something similar but I'm stuck with Kibana 3.1.
I simply added a panel of type "TERMS" and configured its Field = User-agent and left everything else on default values. This gave me a nice bar chart with one bar for each User-agent.
I am working with SSRS and having trouble creating a graphical chart to display data. My dataset is very simple, as it only has one column which is a datetime field (known as CreatedOn).
My SQL query is:
SELECT [CreatedOn]
FROM [Incident]
WHERE CreatedOn > DATEADD(m,-11, DATEADD(
month, DATEDIFF(month, 0,CURRENT_TIMESTAMP), 0))
My goal is to have the query results show up in a chart and have them grouped by year and by month, as well as sorted. For example, I should be able to see that 40 incidents were created in February 2005. Those 40 incidents would be represented graphically as a single bar (it is a bar graph) with the number 40 on top (or somewhere).
My issue is that either my chart shows up completely blank, or the report fails to run. When it fails to run, the error I receive is:
the value expression for field 'CreatedOn' contains an error: conversion from string 'CreatedOn' to type 'Date' is not valid.
I have tried using SSRS expressions on the CreatedOn field, such as CDate() and FormateDateTime(). That does get the report to run, but the chart shows up blank. I would not think that the field should have to be formatted or converted in SSRS since it is already a datetime field at the database level. I have tried about 10 different combinations of groupings and sorts, but my chart always shows up blank. I have even used CDate() and so forth in the grouping and sort expressions which are a part of the chart.
How can I get my bar chart to work (a.k.a. show datetimes, grouped and sorted)?
I am going to go off the assumption:
You have more data being pulled than just the ‘CreatedOn’ field.
a. Because if you don't it will be difficult to create a chart as you have nothing else to compare it too.
If this is an accurate assumption here is an example of how to create a chart and have the data formatted by dates.
When designing a chart you need to take a lot into consideration. First I like to ensure that I have as little null data as possible. This causes charts to act wonky (at least from my experience).
Second is how the data will be represented.
We have several things to consider when we think about charts and groups.
There are Category groups, Series groups, and then the Values.
According to Microsoft: charts have a direct similarity to Matrix’s. They act the same way:
The Column groups of a Matrix are similar to that of the Category Groups in a chart.
The Row groups of a Matrix are similar to that of the Series Groups in a chart.
The Data area of a Matrix is similar to that of the Values Groups in a chart.
Setting Up the chart:
If we want the number of Incidents sorted by Year and then Month it might look something like this:
Year by Category (You can use your group by Expression here) =Year(Fields!CreatedOn.Value)
Incidents will be in the Values section =Count(Fields!Incidents.Value)
Once you have that working and showing data I would then start adding in the data for the month. Again thinking about how you want to have the data displayed. You could then add a second Grouping on the category under the other one with your month function.

*Side Note: When dealing with dates it can be a little tricky especially if SSRS is not recognizing something as a date. Here is a useful link that I have used when dealing with dates.
Dates
I hope this helped!
The issue was that the CreatedOn date field was not being defined correctly.
My data source was defined using an expression which depended upon parameters, using the expression: ="Data Source=sql01;" & "Initial Catalog=" & Parameters!ParentID.Value. Because the dataset must be defined at the runtime of the report, I was not able to refresh fields in the dataset using the "Refresh Fields" button.
I thought that I could work around this by defining the CreatedOn field manually. On the first attempt, SSRS threw an error at runtime claiming that I was trying to convert a string to a date, which basically meant that it perceived the CreatedOn field as defined within the dataset as a string. So I then tried to use the CDate() expression in the definition of the field, but that left me with a completely blank graph.
The solution was to:
Delete all of the fields I already had defined within the dataset
Temporarily hard-code my data source to use a database (Data Source=sql01;Initial Catalog=MyDatabaseName)
Click the "Refresh Fields" button within the dataset
Go back at set the data source to the original data source I wanted which depended upon parameters.
I have an xPage which I have built with 3 combo boxes and 1 view control. I would like to use the 'Filter by column value' option within the view control to provide the options to filter the values, allowing the user to display any combination of the combo boxes. e.g. Only comboBox1, or comboBox1 and comboBox2, or comboBox3 only, or comboBox1 and comboBox2 and comboBox3.
I used the example in the 'xPages Demonstration Application' (http://www-10.lotus.com/ldd/ddwiki.nsf/dx/xpagesdemoapp.htm or http://xpagesblog.com/XPagesHome.nsf/Entry.xsp?documentId=AAC8E26599256FDC852578CB0066CC13) to do the multi-column filtering using a vector of non-categorized columns.
So, I have come across what appears to be a fairly major issue whereby the data needs to be sorted by date. Date is not one of the filters, but it needs to be the first column in order for the data to be sorted correctly. So my first column is a string, YYYYMMDD, to ensure the data is sorted correctly. I tried to use the sort option within the view control and that does not appear to work with the column filtering implemented in this manner.
So, as Date one of the criteria I am filtering by, I have passed that as an empty string - using the thought process that an empty string will select all (as in the url examples above).
The code I have used to do the filtering is:
var vtr:java.util.Vector = new java.util.Vector();
var t1 = sessionScope.Email;
var t2 = sessionScope.Own;
var t3 = sessionScope.Module;
vtr.addElement("");
#If(sessionScope.Own=="My calls",vtr.addElement(t1),vtr.addElement(""));
#If(sessionScope.Own=="My calls",vtr.addElement(""),vtr.addElement(t2));
#If(sessionScope.Status=="Open",vtr.addElement("Open"),vtr.addElement(""));
#If(sessionScope.Module=="All",vtr.addElement(""),vtr.addElement(t3));
return vtr;
What I have found is that not all data is being returned. I thought this might be due to the date field. So I removed it (changing the view and removing the first add element), and yet I still find that not all data is being returned. I suspect that this might be due to the empty strings being passed, or, that this does not actually work the way I had hoped.
Does anyone know if I can get this working the way I want it to, and if not, do you have any suggestion on how I can go about this?
Date is not needed as the first sortable column in the view. The first column does need to be sorted for the lookup to work just like the Notes view needs to be sorted for #DbColumn and #DbLookup to work. XPages uses the same underlining architecture. This example - http://dev.openntf.org/demos/demoapp.nsf/viewFilteringVector.xsp - works without the data being sorted by Date.
My guess as to why your example isn't working is down to how your Notes view sorted. Try creating a new view with column 1 (email) ascending sort, column 2 (own) ascending sort, and column 3 (module) again ascending sort. You should be able to get vector filtering working in this situation.
If all that doesn't work for you, you might consider multi-layer category filtering (new to 853). This filtering type in XPages is related to how categoryFilter works but allow you to filter a view by the sub-category (or sub-categories) too. This technique might suit your scenario better. Hope this helps.
I have a table that contains three columns.
"UserId" type-nvarchar
"PostAuthorId" type-nvarchar
"Post" type-text
This table will contain "wall" posts like in facebook for each user's page. I am going to use a gridview on each user's page to display the posts. The issue is I want to display them with the latest(most current) post being first and the earliest post being last.
I have never used autoincrement before and I am not sure if that is the answer. If it is, I do not know how to use it. I thought about adding a date posted column and then ordering by date.
If I end up using the date column, I could also display the date on the post. Is there a way to convert the date to a readable format?
What is the best way of implementing this type of ordering?
If you use AutoIcrement the first record will start with 1 and each record will increment from there. (default setting)
If you want to sort them by newest first do an ORDER BY ID DESC
I would suggest making a column called wallPostID then setting that to AutoIncrement and also your Primary Key
Date Formating:
If you are displaying this data in a gridView
Go to Edit Columns on your grid view
CLick on the Date field under "Selected Fields" on the bottom left
Under "BoundField properties" on the right Go to Data -> DataFormatString
{0:d} will display as 1/1/2010
This site has more info in string formatting
http://msdn.microsoft.com/en-us/library/fht0f5be.aspx
A datetime column would definitely work for something like this. Assuming you are using MS-SQL, you can also attach a default value to the column using a built-in function like GETDATE(). That way, you only have to input the data that matters and the database will take care of adding the datetime column.
For converting a datetime to a readable format try:
DateTime postDate;
string value = postDate.ToShortDateString();
You should always use an ID field that auto increments. Can also be used as your PK
I would suggest the DateTime field rather than the autoincrement simply because it will not only serve as an effective Sort field, it also preserves information that you may well want to display. If you want the most recent first you'll sort using the Date and a "DESC" modifier:
Select ... Order By [Date] DESC;
When you retrieve the data, you can retrieve it as a DateTime and modify it using C#. You can use "ToShortDateString()" as suggested by mdresser if you just wish to show the date or ToString("...") if you wish to show the time as well. You can also use SQL to convert it into a string before retrieving it:
convert(Varchar(10), #mydatetime, 101)
If you look in MSDN you'll see the various conversion codes (101 is the code used above) that can be used to translate the date in various ways.
UPDATE: You may want to use an autoincrementing field for your application for reasons other than your expressed need to sort wall entries. They are easy to use - just mark the field as an Identity if using SQL Server (other DBs are similar). As far as using them in your program, just think of the field as an Int field that you never have to set.
Now, why would you use a auto-incrementing field? Perhaps the most straightforward reason is so that they give you have an easy way to identify each record. For example, if you permit people to alter or delete their wall entries, the auto-incrementing field is ideal as it gives you a way to easily look up each record (each record will be assigned its own, unique value). You might put an "x" next to the record like StackOverflow does and make it a call back with the UID (auto-increment) value. Note that you should set up your primary key on the UID field if you'll be doing this.
Now, if you find them useful for this reason then you could also sort by the UID. I would still store the date so that you can provide Date and Time feedback as to when an entry was made on the wall but this would no longer be your indexed or sorted field.
