I need a solution to the following or a link to a detailed parameter guide that describes a Mapserver MapFile DATA element so I can try and work out a solution.
I'm trying to pass a dynamic filter to the mapfile but can't work out the syntax to do so.
The context is having a web-application where I have a WMS layer in Openlayers that connects to a Mapserver Mapfile which in turn is reading from a PostGIS raster DB.
The vector layers version of this approach has the following base syntax which is fine and works for vector tables in the DB:
DATA "geom FROM some_table using unique id using srid=4326"
FILTER (id = '%id%')
In effect this generates an SQL statement where the FILTER is created as a where clause in the DATA SQL.
However, in a raster DB example the DATA syntax shown at this link [http://postgis.net/docs/RT_FAQ.html#idm28328] is as follows:
DATA "PG:host=localhost port=5432 dbname='some_db' user='some_user' password='some_password' schema='some_schema' table='some_table' where='id=12' mode='2' "
So I can get things to work with hardcoded where elements, i.e. id=12 but in the previous example I could set the id parameter dynamically in the Openlayers WMS query through the FILTER line.
Does anyone know of the syntax to achieve this in the raster DATA example or is it even possible?
you need to add a "validation" object to your id type.
Add something like:
VALIDATION
'id' '[0-9]+'
END
to your layer object.
You can see that page for more explanations:

I am trying to get JSON data from an API in robot framework which has data with id's. I have to get the count of id's present in the data obtained from the API.
I have tried the below code:
${result} = get ${API_JSON_PATH}
Should Be Equal ${result.status_code} ${200}
${json_data} = Set Variable ${result.content}
Log ${json_data}
I am getting the below mentioned error:
No keyword with name '${result} = get' found.
Is the approach correct or is there any other better ways for getting the JSONS data?
I'm using the RequestsLibrary and it's slide different from what you are doing.
the credential are not needed in your case but this is the example:
#{credential}= Create List Your_Username Your_Password
Create Session YOUR_API_ALIAS YOUR URL auth=#{credential}
${api}= Get Request YOUR_API_ALIAS YOUR_URI
if you want get the content of the JSON:
${api.json()}
Documentation: https://bulkan.github.io/robotframework-requests/
You need to have two or more spaces after the =. Robot looks for two or more spaces to find keywords and arguments, so it thinks your first statement begins with the keyword ${result} = get. Since that's not a valid keyword, you get that error.
I am trying to show images for products inside a basic report. The image needs to be dynamic, meaning the image should change based on the SKU value.
Right now I am inserting an image into a table, setting to external, and i've tried:
=Fields!URL.Value
=http://externalwebservername/sku= & Fields!SKU.Value
="http://externalwebservername/sku=" & Fields!SKU.Value
I do not get any images in my table.
My stored proc has all the data, including a URL with the image I wan't to show. Here is a sample of what the URL looks like:
http://externalwebservername/sku=123456
If I enter the URL in the field without "=" it will show that ONE image only.
How should I set up the expression to properly show the external image based on a dynamic URL? Running SQL 2016
Alan's answer should work, but in our environment we have strict proxy/firewall rules, so the two servers could not contact each other.
Instead we are navigating to the file stored on our storage system.
We altered the URL column to point to file path in the stored procedure. Insert image, set Source to External and Value set to [URL].
URL= file://server\imagepath.jpg
As long as the account executing the report has permissions to access the URLs then your 3rd expression should have worked.
I put together a simple example as follows.
I created a new blank report then added a Data Source. It doesn't matter where this points, we won't use it directly.
Then I created a dataset (Dataset1) with the following SQL to give me list of image names.
SELECT '350x120' AS suffix
UNION SELECT '200x100'
UNION SELECT '500x500'
Actually, these are just parameters for the website http://placehold.it/ which will generate images based on the size you request, but that's not relevant for this exercise.
We'll be showing three images from the following URLs
http://placehold.it/350x120
http://placehold.it/200x100
http://placehold.it/500x500
Next, create a table, I used 3 columns to give me more testing options. Set the DataSetName to DataSet1 if it isn't already.
In the first column the expression is just =Fields!suffix.Value
In the second column I added an image, set it's source property to External and the Value to ="http://placehold.it/" & Fields!suffix.Value
I then added a 3rd column with the same expression as the image Value so I could see what was being used as the image URL. I also added an action that goes to the same URL, just to check the URL did not have any unprintable characters in it that might cause a problem.
The basic report design looks like this.
The rendered result looks like this.
I have been developing a web application using domino, therein I have dblookup-ing the field from notes client; Now, this is working fine but the format of value is missing while using on web.
For example in lotus notes client the field value format is as above
I am one, I am two, I am one , I am two, labbblallalalalalalalalalalalalalalalalalalaallllal
Labbbaalalalallalalalalalaalallaal
Hello there, labblalalallalalalllaalalalalalalalalalalalalalalalalalalalalalalala
Now when I retrieve the value of the field on web it seems it takes 2 immediate after 1. and so forth, I was expecting line feed here which is not happening.
The field above is multi valued field. Also on web I have used computed text which does db lookup from notes client.
Please help me what else could/alternate solution for this case.
Thanks
HD
Your multi-valued field has display options associated with it and the Notes client honors those. Obviously, your options are set up to display entries separated by newlines.
The computed text that you are using for the web does not have options like that and the field options are irrelevant because you aren't displaying the field. Your code has to insert the #Newlines. That's pretty easy because #DbLookup returns a list, and if you concatenate a list and a scalar, the scalar will be appended to each element of the list. (Look at the third example under "concatenation, pairwise" here to see what I mean.
The way you've worded your question is a little unclear to me, but what you need in your computed text formula is either something like this:
list := #DbLookup(etc,. etc.);
list + #Newline;
Or something like this:
multiValueFieldContainingListWithDbLookupResult + #NewLine;
I used #implode(Dblookupreturnedvalue;"");
thanks All :)
I have a view in my 1010data base and it has created by someone else I want to identify its description and is their a direct api call to get that information.
Already tried with following Commands. it gave following errors.
using dir api endpoint.
<out>
<rc>15</rc>
<msg>Not a directory: xxx.views.test</msg>
</out>
using tabinfo endpoint.
<out>
<rc>22</rc>
<msg>Not currently implemented for Quick Query: XXX.views.test</msg>
</out>
Is their a command to see the structure of view and related tables?
I can retrieve column names using querydata api end point but i cannot get informations related to linked tables.
Is their a command or endpoint to get this information.
Something like Show create view in Mysql :)
Have you tried gettab ?
documentation is here:
https://www2.1010data.com/documentationcenter/beta/XMLAPI/TableManagement/XMLAPI-gettab.html
It says there "If the table is a query (i.e., type is VIEW, PARAM, MERGED or TOLERANT) then the tab element will contain ops and dependencies elements. Any dependencies on other tables (i.e., links, merges) are available in the element, which contains a list of table references if the table is a Quick Query or a merged table."
Can you please confirm if that works for you?
Thank you!
I'm just starting out with the Google Analytics API and am wondering if it's possible to compare two dimensions via an operand in the filters I pass in the query. And by wondering I mean I've tried it, but have had no success.
Specifically I'm trying to compare 2 custom variable values. One holds the user who created a post (customVarValue3), the other the user who is viewing the post (customVarValue5). I want to get the pageviews only for the visitors who are not also the creator. The filter looks like this (without urlencoding applied):
ga:customVarValue3!=ga:customVarValue5
The full query (url encoded) looks like this:
https://www.google.com/analytics/feeds/data?ids=ga%3Axxxxxx&dimensions=ga%3AcustomVarValue1%2Cga%3AcustomVarValue2%2Cga%3AcustomVarValue3&metrics=ga%3Apageviews&filters=ga%3AcustomVarValue3!%3Dga%3AcustomVarValue5&sort=-ga%3Apageviews&start-date=2012-02-09&end-date=2012-02-23&max-results=50
However, it returns the same results (and I know there are results where ga:customVarValue3 == ga:customVarValue5).
Probably it isn't possible, but I just wanted to see if anyone knew how to achieve this or has a workaround or something.
No, it is not possible using the GAv3 API in its present state. You can, however, get all the results by using the specified two custom variables as the dimensions for a report, and programmatically filter out the unnecessary results.
Some simple construct like
for(var item in collatedResultsListwithDimensions) {
for(var row in item.rows) {
if(row[0]!=row[1])
newResultRows.push(row);
}
}
Now your newResultRows will have those rows where row[1]!=row[0] assuming the two custom variables you mentioned are the first two dimensions.
