Mule4 consuming rest API(s)

localhost:8081/getproduct/? productids=5d668dab0be6a263d464e822&productids=5d668daf0be6a263d464e823
have this API. How to set it in query param of mule4? I am using set variable for that but then I am able to pass only one productid using attribute.queryParams.productIds, but I need to pass list of productIds. How to do it using setVariable?

SugarCRM custom field

I'am writing a software for the data-synchronization of a custom software and sugarCRM. Therefore I need an updateOrCreate() function. My Problem is, that the custom software uses other uuid´s than sugarCRM so i can´t look for the uuid to check on update or create.So I want to save the custom-uuid in a custom field of sugarCRM.
But i have no idea how to do that over the REST-API of sugarCRM.
By the way I wrote a java-application.
Thank you for help!

As far as I'm aware there is no update-or-create API (see https://your-sugarsite/rest/v10/help), howewer if you just want to use the API (rather than customize it) you could sync data like this:
1) Fetch all ids of records that have a custom uuid by using the POST /rest/v10/<module>/filter endpoint and a payload similar to:
{
offset: 0,
max_num: 1000,
fields: ["id", "custom_uuid_c"],
filter: [{"custom_uuid_c": {"$not_empty": ""}}],
]
}
or if you just need a specific custom uuid at a time:
{
offset: 0,
max_num: 1000,
fields: ["id"],
filter: [{"custom_uuid_c": {"$equals": "example-custom-uuid"}}],
]
}
The response will look something like this:
{
next_offset: -1,
records: [
{"id": "example-sugar-uuid", "custom_uuid_c": "example-custom-uuid"},
...
],
}
Notes:
Make sure to evaluate next_offset as even with a high max_num you may not get all records at once because of server limits. As long as next_offset isn't -1 you should use its value as offset in a new request to get the remaining records.
You can supply all field names you need to sync in the fields array, so that you get that information early and can check whether or not an update is required at all (maybe data is still up-to-date?)
Sugar also always include certain fields in the response, no matter if they were requested or not. (E.g. id and date_modified). I did not include them all in the response snippets for the sake of simplicity.
2)
Based on the information received in the previous step you know which sugar ID belongs to which custom UUID and you can detect/prepare data for updates.
If you need to sync all and retrieve the complete list first, I suggest you create a lookup table custom-uuid => sugar-id, so that you do not have to loop through the data array and compare fields when looking for a specific number.Don't forget to consider the possibility of a custom-uuid being present in one than more Sugar-record at a time, unless you enforce them being unique on the server/database side.
3)
Now that you have all the information you need you can update and create records as needed:
Update existing record: PUT /rest/v10/<module>/<record_id>
Create missing record: POST /rest/v10/<module>
If want to send a lot of creates and/or updates in a single request, have a look at the POST /rest/v10/bulk API - if your version of Sugar has it.
Final notes:
The filter operators definition on /rest/v10/help seems incomplete, for more info you can check the filter docs

Change a property dynamically from the payload on mule esb

I'm developing a bookstore in mule esb. When I check the quantity from a book order is available with the database, I want to set a property from payload. The payload has several properties from the book (isbn, quantity, prize, avalability), so the last one in this case I want to set to true (is attribute boolean type).
Is there any way to do that with a connector?

not really sure what you're trying to do but...
To change the payload of a message there several ways the easies one being just using a MEL expression.
Say your payload is a map(for you say you toke it from the DB) then you could just do:
<expression-transformer expression="#[payload['avalability']='your value']"
Now you say you wanted that value to be true then the code should look like:
<expression-transformer expression="#[payload['avalability']=true]
MEL will put a boolean true for you there.
Finally to update the DB you should:
<db:update config-ref="Database" bulkMode="true" doc:name="insert contacts to Database">
<db:parameterized-query>
UPDATE books
SET 'avalability' = #[payload['avalability']]
WHERE 'isbn'= #[payload['isbn']]
</db:parameterized-query>
</db:update>
If you want more example about working with DB please check:

You can set the propertyName dynamically using:
#[message.outboundProperties.propertyName]=any value

How to get last status message of each record using SQL?

Consider the following scenario.
I have a Java application which uses Oracle database to store some status codes and messages.
Ex: I have patient record that process in 3 layers (assume 1. Receiving class 2. Translation class 3. Sending class). We store data into database in each layer. When we run query it will show like this.
Name Status Status_Message
XYZ 11 XML message received
XYZ 21 XML message translated to swift format
XYZ 31 Completed message send to destination
ABC 11 XML message received
ABC 21 XML message translated to swift format
ABC 91 Failed message send to destination
On Java class I am executing the below query to get the last status message.
select STATUS_MESSAGE from INTERFACE_MESSAGE_STATUS
where NAME = ? order by STATUS
I publish this status message on a webpage. But my problem is I am not getting the last status message; it's behaving differently. It is printing sometimes "XML message received", sometimes "XML message translated to swift format", etc.
But I want to publish the last status like "Completed message send to destination" or "Failed message send to destination" depending on the last status. How can I do that? Please suggest.

You can use a query like this:
select
i.STATUS_MESSAGE
from
INTERFACE_MESSAGE_STATUS i,
(select
max(status) as last_status
from
INTERFACE_MESSAGE_STATUS
where
name = ?) s
where
i.name = ? and
i.status = s.last_status
In the above example I am assuming the status with the highest status is the last status.
I would recommend you to create a view out of this select query and then use that in your codebase. The reason is that it is much easier to read and makes it possible to easily select on multiple last_statuses without complicating your queries too much.

You have no explicit ordering specified. As the data is stored in a HEAP in Oracle, there is no specific order given. In other words: many factors influence the element you get. Only explicit ORDER BY guarantees desired order. And/or creating a index on some of the rows.
My suggestion: add a date_created field to your DB and sort based on that.

How do I extract a value from the URL

I have a URL www.test.com/myshort/myapp/mypage.jsp, where myshort is a column value in my database.
I will later query for the id of this shortName (in this example it is 'myshort') which I am doing as
select id from mytable where shortName='myshort';
How can I extract the 'myshort' value from the entire URL? I can't do request.getParameter() since this is not a part of the url parameter. So I am trying to use request.getURI().
Can you please tell me how do I parse and get shortName using request.getURI()?

I suggest the use of Spring MVC framework for this type of server programming. It gives you the ability to map request patterns with the actual urls and extract such values from the URL.

I figured out a solution/alternative to my issue. I could go ahead and edit web.xml and specify the url format there.
But this is how I solved my issue. I took off the shortName coming from the url and sticked it as URL parameter. this is much more easier to access than what I was thinking earlier.
