I'm really new to ColdFusion and am trying to pull data out of the database and send it to an email function I have created.
myQry = new Query();
myQry.setSQL("select * from stocknotifications LEFT JOIN options ON stocknotifications.stocknotification_id = options.option_id ORDER BY stocknotification_id DESC LIMIT 1 "); //set query
qryRes = myQry.execute();
writedump(qryRes.getResult(), false);
Mail = variables.NotificationService.newMail();
Mail.setTo("bfrench#destinationcms.co.uk");
Mail.setSubject( "New Stock Request" );
// render body with layout which uses the rc.emailView
Mail.setBody(ToString(qryRes.getResult()));
variables.NotificationService.sendMail( Mail );
My writeDump() works and shows the last item in table. The only problem is I can't pass it into setBody() without it throwing an error.
Can't cast Complex Object Type Query to String
Use Built-In-Function "serialize(Query):String" to create a String from Query
Any ideas?
Per the error message you received, you could actually replace toString with serialize and you'd be good to go.
If all you want is the data going to e-mail without caring about presentation, quick and dirty, you might want to try SerializeJSON(); it will convert the query into a JSON string with COLUMNS and DATA:
Mail.setBody(SerializeJSON(qryRes.getResult()));
The easiest way to do this is with cfsavecontent. I'm not sure if there is a script version of this so I'll show you how to use is with tags. You already have a query result named qryRes.
<cfsavecontent variable = "eMailBody">
<cfoutput query = "qryRes">
#field1#, #field2# etc
</cfoutput>
</cfsavecontent>
Then for mail function, you can do this:
mail.setBody(emailBody);
If you want to send your email in html format, put the appropriate html tags inside the cfsavecontent block. Otherwise, pay attention to the carraige returns of your source code. They get included in the variable produced by cfsavecontent. For the code sample above, you will get 3 blank lines at the top of the body, and the data rows will be double spaced.

I am trying to import data from sharepoint rest API using the document id of all the documents. My objective is to start from the smallest document id and move on until there are no more documents.
I have designed a custom function and i am calling it by passing the Document Id which i am starting from 0. This function return me a table containing 500 documents whose Doc Id is greater than the Document Id which i am passing.
#"Output" =Table.AddColumn(Termset,"c", each GetList( try List.Max(Output[c.DocId]) otherwise LastDocID))
So my data is updated in the Output table. My problem here is that it is returning the same set of 500 recs again and again. Which is possibly because the value of List.Max(Output[c.DocId] is not changing (i want this value to be the last document id which is returned from GetList function) . I am trying here to do someting like a do while loop.
do{
Output=GetList(LastDocID)
LastDocId=List.Max(Output[DocId])
}while(there_are_no_more_docs)
Is there any way in Power Query that i can dynamically change the value of LastDocId which i am passing to the GetList function. The method which i tried below does not seem to be working as it is not able to read the contents of the Output table after every function call.
Note: I am using Termset as pages to put a check on the total documents being read. It is a list whose value starts from 0 and increments by 500 until it is less than the total number of docs in Sharepoint.
I would really appreciate if somebody can help me here.
You need to look at List.Generate to generate all of your page requests and then compute the last document id from the list of results.
Use a loop like the following to fetch all pages from the REST API:
listOfPages = List.Generate(
() => FetchPage(null),
(page) => page <> null,
(page) => FetchPage(page)
)
I have created a microservice pipeline in streamsets. Upon making a get callout, i have to retrieve data from mysql depending on the parameters sent in the http get url using expression evaluator?
My url is supposed to be like this: http://my.url.com:0191?param1=xyz¶m2=abc
I have to retrieve data based on param1 value and param2 value.
Also, how do I handle cases when the params send will be null?
The URL parameters appear in the queryString record header attribute; you can parse them out in an Expression Evaluator with the Field Expression:
${str:splitKV(record:attribute('queryString'), '&', '=')}
If you set the Output Field to /, then your parameters will now be in the fields /param1 and /param2. You can use these in a MySQL query in the JDBC Lookup processor like this:
-- Assuming col1 is an integer (doesn't need quotes) and col2 is a string (needs quotes)
SELECT * FROM tablename
WHERE col1 = ${record:value('/param1') AND col2 = '${record:value('/param2')'
You can handle nulls using the record:attributeOrDefault() function to set a default, or by using a Stream Selector to send the record along a different path.
My Scenario:
I have a report on page 1 which has a link to page 2. This link passes an ID to page 2 (V2_ID gets set with V1_ID).
I then have two items called V2_ID and V2_NAME on page 2, as well as a PL/SQL process on page 2 which executes after the header loads which
select name into :V2_NAME from table where id = :V_ID;
The V2_ID shows the value, but the V2_NAME is always blank.
How can I pre-populate this variable. This is a very simple example as my use case is much more complicated, but the concept is the same. I can't use automatic row fetch because each item comes from a different table (it is a horrible database design, but I have to work with it).
Cheers
If on page 2 you have a PL/SQL process at the process point='On Load - After Header' and the procedure looks something like this:
Begin
select name into :V2_NAME from table where id =:V2_ID;
end;
and no condition on it then it should work.
Check that :V2_NAME does not have Source Type= Always NULL;
Correct me if Im wrong, from what ive understood, only one value is passed from page 1 to page 2 which is V1_ID to V2_ID,right?then on page 2, you have a process that will execute after the header loads and that is
SELECT name
INTO :V2_NAME
FROM TABLE
WHERE id = :V_ID
Is the :V_ID a typo?It should be :V2_ID,if its not maybe its the cause as to why :V2_NAME doesnt give you a value.
Instead of having a process after header, why dont you just put the query in the item SOURCE, choose type: QUERY, used: ALWAYS, REPLACE ANY EXISTING VALUES ON SESSION STATE.
then in the query box, put
SELECT name
FROM TABLE
WHERE id = :V2_ID
So last week I was able to begin to stream my Appengine logs into BigQuery and am now attempting to pull some data out of the log entries into a table.
The data in protoPayload.resource is the page requested with the querystring paramters included.
The contents of protoPayload.resource looks like the following examples:
/service.html?device_ID=123456
/service.html?v=2&device_ID=78ec9b4a56
I am getting close, but when there is another entry before device_ID, I am not getting it. As you can see I am not great with Regex, but it is the only way I think I can parse the data in the query. To get just the device ID from the first example, I was able to use the following example. Works great. My next challenge is to the data when the second parameter exists. The device IDs can vary in length from about 10 to 26 characters.
SELECT
RIGHT(Regexp_extract(protoPayload.resource,r'[\?&]([^&]+)'),
length(Regexp_extract(protoPayload.resource,r'[\?&]([^&]+)'))-10) as Device_ID
FROM logs
What I would like is just the values from the querystring device_ID such as:
123456
78ec9b4a56
Assuming you have just 1 query string per record then you can do this:
SELECT REGEXP_EXTRACT(protoPayload.resource, r'device_ID=(.*)$') as device_id FROM mytable
The part within the parentheses will be captured and returned in the result.
If device_ID isn't guaranteed to be the last parameter in the string, then use something like this:
SELECT REGEXP_EXTRACT(protoPayload.resource, r'device_ID=([^\&]*)') as device_id FROM mytable
One approach is to split protoPayload.resource into multiple service entries, and then apply regexp - this way it will support arbitrary number of device_id, i.e.
select regexp_extract(service_entry, r'device_ID=(.*$)') from
(select split(protoPayload.resource, ' ') service_entry from
(select
'/service.html?device_ID=123456 /service.html?v=2&device_ID=78ec9b4a56'
as protoPayload.resource))
I have a report stored as an .cfm file. I have been able to retrieve it fine with a cffile read. Now I want the option of retrieving only part of the report, say the first 50 lines. I decided to try a fileReadLine():
<cfset repname = url['rep']>
<cfset type = url['type']>
<cfset dataFile = fileOpen("/var/www/reports/moxrep/#repname#.cfm", "read" ) >
<cfset i = 0>
<cfoutput>
<cfloop
condition = "NOT FileIsEOF(dataFile) AND i LT 100">
<cfset i = i + 1>
<cfset inf = fileReadLine( dataFile ) >
#inf#
</cfloop>
</cfoutput>
<cfset fileClose( dataFile ) >
It did not retrieve things at all correctly. The formatting was messed up. All the dynamic data in the report was missing. The CSS links did not operate. And there were many extra blank lines.
Am I doing something wrong? Or is fileReadLine just not meant for retrieving a formatted report? And if not, is there any way to retrieve just part of the report with cffile?
Use cfhttp to get the report, then take that result and strip it down to what you need.
I am not sure you realize that the FileOpen() function is actually reading the raw CFML template and not actually executing the queries that populate your report. Using the CFHTTP tag is definitely a better approach, but be careful because your rendered page is likely to contain all your CSS that would be necessary for the report to render properly so use View Source on your report to see if you want just 50 lines.
The question burning in my mind is "why" do you want just 50 lines? are you previewing the report? it is only 1 page long? Are you embedding it into a dashboard? You may want to consider modifying the .cfm "report" so that the area you want to display elsewhere is wrapped with a specific tag (such as a Span or even something custom) and then when you fetch the report using CFHTTP, then you can parse the results with XMLParse() function (assuming it is properly formatted) and render the section of the report you actually want.
