I'm looking a sample dashboard "Map Component Full Test".
I want to replace the datasource of pie chart for "sql over sqljdbc".
How can I use parameter in SQLQuery?
I'm waiting for your answer.
If you want to use parameter in SQL Query,
write Query like this.
Query:
select * from table
where id = ${parameter_name}
And another property should be set like this.
parameter:
Arg ← parameter_name ,
Value ← not set (this value is affected by graph component's setting)
※here, "parameter" does not mean the components, like "Simple
parameter".
They are not same.

I am using a SQL notebook in Databricks/Spark community edition
%python
education_DF = sqlContext.sql('select * from global_temp.population_Globaltmp_view where `Education` = "2YD"')
display(education_DF)
The above code cell works fine and retrieves the desired rows from the view.
However the following code cell gives an error.
I am supbstituting the hard-coded value "2YD" in the WHERE clause, with a variable call education_choice that contains the same value.
It seems that I am not using variables correctly in SQL. How would I make this work?
%python
education_DF = sqlContext.sql('select * from global_temp.population_Globaltmp_view where `Education` = education_choice')
display(education_DF)
(This is the error)
org.apache.spark.sql.AnalysisException: cannot resolve '`education_choice`' given input columns: [global_temp.population_globaltmp_view.Salary, global_temp.population_globaltmp_view.Address, global_temp.population_globaltmp_view.Race, global_temp.population_globaltmp_view.MiddleI, global_temp.population_globaltmp_view.Education, global_temp.population_globaltmp_view.HairColor, global_temp.population_globaltmp_view.Age, global_temp.population_globaltmp_view.FullName, global_temp.population_globaltmp_view.City, global_temp.population_globaltmp_view.FirstName, global_temp.population_globaltmp_view.State, global_temp.population_globaltmp_view.LastName, global_temp.population_globaltmp_view.Height, global_temp.population_globaltmp_view.Fertility, global_temp.population_globaltmp_view.Employment, global_temp.population_globaltmp_view.Zip, global_temp.population_globaltmp_view.Weight, global_temp.population_globaltmp_view.Gender]; line 1 pos 72;
I tried the injection method suggested, but got a slightly different error this time. I included a screen shot of the relevant code cells. It seems that the education_choice "2YD" isn't being recognized as a literal but a field or something like that.
Shouldn't 2YD have quotes around it like "2YD"
If I hard code the WHERE clause like this: WHERE Education = "2YD" the queries works fine.
The image bellow is small but if you right click on it and "open in new tap, it is very readable.
*EDIT
You use the variable education_choice as a hardcoded string. Instead, you should inject the value of education_choice inside the SQL expression string like that.
*edit - wrap the variable with quoets.
%python
education_DF = sqlContext.sql('select * from global_temp.population_Globaltmp_view where `Education` = "{}"'.format(education_choice))
display(education_DF)
I have a variable obtained by query component, I want to pass it to a query on Data sources that will be used by another query component, here is what I did:
1) DataSources - sql_company_id :
2) first Query Component :
With a JS function on Post Fetch:
function f(company_id) {
dashboard.setParam('company_id', company_id.resultset);
}
So company_id=1 in my example.
3) DataSources - sql_company_name
with parameter defined like below:
4) second Query Component :
with Post Fetch like this:
It is supposed to display the company name having company_id='1' but nothing appears.
When I change the second query to:
select company_name
from company
where company_id=1;
Then it works.
I'm not using correctly the variable {company_id} I suppose.
I had a very similar prob and got the solution so I did in the same way this time. Where I got wrong?
Using Postman, I am forming a GET request query to my P21 database middleware to retrieve items with a specific value in a UserDefinedField.
I am able to query things on the top level of the item data, such as ItemID and ItemDesc like so:
http://[server]:[port]/api/inventory/parts?$query=ItemDesc eq 'CONTROL VALVE'
However, the values I would like to use in my query string are nested inside the UserDefinedFeilds element. I am specifically looking for items with:
http://[server]:[port]/api/inventory/parts?$query=UserDefinedFeilds/OnEbay eq 'Y'
But this is not the correct way to form this query string. Can anyone please explain how to specify a nested element inside a query string like this? Thanks.
In this situation, using P21 API, it is unnecessary to specify the parent field 'UserDefinedFields'. The actual ID of the column I was looking for was actually 'on_ebay', so I was able to query this user defined field simply:
http://[server]:[port]/api/inventory/parts?$query=on_ebay eq 'Y'
I am using Sybase 15 and have a SP which returns a result set like this:
SELECT foo,
bar,
etc,
xyz,
...
#temp_id
FROM #table
ORDER BY 2,3 DESC
When this gets to iReport the query shows the field name is blank. It knows that the field type is java.lang.Integer but I can see no way to create a field for it in the report. If I give it a name - #temp_id I get an error telling me the field isn't found. Same thing if I try it in JasperReports.
The strange thing - to me anyway - is that in my Eclipse data explorer it also shows no label for that column. Nor does it for the JasperReports Dataset and Query Dialog when I ask it to Read Fields.
I tried just calling it COLUMN_15 but that didn't work either.
What am I missing?
Ok, I have a simple process...
Read a table and get the rows that
have a "StatusID" of 1. Simple.
Select ProductID from PreorderStatus where StatusID = 1
Foreach row returned from that
query, perform an action. For
simplicity sake, let's just modify
the original table to set the
"StatusID" to 2.
Update PreorderStatus set StatusID = 2 where ProductID = #ProductID
In order to do this in SSIS, I have created a simple "Execute SQL Task" with the first statement. In the editor I have set the Result Set to return a Full result set and the Result Name of 0 is set to fill an object variable named ReadySet.
The output is then routed to a For Each Loop container. The Enumerator is set to Foreach ADO Enumerator and the object source variable set to the ReadySet variable from above. I have also mapped the variable v_ProductID to index 0.
Setting a breakpoint at the begining of the Foreach loop shows the variable being set correctly. GREAT!! Now on to step two....
Now I have placed a new SQL task in the foreach container. Now I have a head scratcher. How do I actually use the variable in the SQL statement. Simply using "v___ProductID" or "User::v_ProductID" doesn't seem to work. Mapping a parameter seemed like a good idea (got a #ProductID and everything!) but that didn't seem to work either.
I get the feeling that I am missing something pretty simple but can't tell what. Thanks for any help!!
I think there is a better approach. Here are the approximate steps:
Drag a DataFlow task onto the design surface.
Open it up and add a OLE DB source and OLEDB Command components to the design surface.
Modify the source to use the query you have described.
Connect the source to the Command component.
Modify command component to use "Update PreorderStatus set StatusID = 2 where ProductID = ?" query and on param mapping page map the ? variable to the input coming from the datasource.
HTH
When I want to use an execute sql task and vary something based on a variable, I use a stored proc and make the variable the input parameter for the proc.
Then you set the parmeter in the execute SQL task and set the SQL statement to something like:
exec myproc ?
