JMeter retrieve value of value - jmeter

I am using jmeter to test ldap.
As part of my test, I want to search for a random uid on each iteration. I did not find a straight forward answer to this. So my idea was to first select a random number 1-200 and saving that number as a variable named uid, that number would correspond to a UDV name.
For example
uid = 2 and 2 = A123456
in my udv list. However when trying to reference this variable in my ldap search filter.I am trying to use
(uid=${${uid}})
in hopes to get the value of the value of uid. However the search results just show this as a string.
<searchfilter>(uid=${${uid}})</searchfilter>
Is there another way to achieve what I am looking for?

Use __V function
${__V(${uid})}
The V (variable) function returns the result of evaluating a variable name expression. This can be used to evaluate nested variable references
${__V(A${N})} - works OK. A${N} becomes A1, and the __V function returns the value of A1

Perhaps the easiest would be going for __RandomFromMultipleVars() function?
Another option is using __V() function, it can combine and evaluate JMeter Variables

How to get variable names in Mathematica timeseries?

I am using the predefined "WindSpeedData" function, which returns a TimeSeries object. How can I get the variable names that constitute the time series and their corresponding data?
Found the answer.
Use "Values[WindspeedData[...]] "

How to increase int value obtained from previous response

I'm using jmeter and I would like to automate below scenario :
(In general I would like to increase value, I already know how to extract value from previous request)
Execute request_1
Extract value1 from request_1 using Regular expression extractor
Increment value1.
Put new value (increased) to the request_2
Any idea how can I achieve it ?
Check out __intSum() function, you can sum an arbitrary number of arbitrary integers via it.
Given you have a JMeter Variable called yourVar where the extracted value lives, the relevant __intSum() function configuration to increment ${yourVar} value by 1 will be something like:
${__intSum(${yourVar},1,yourVar)}
Demo:
If the value you're getting from the Regular Expression Extractor is more than 2 147 483 647 you will need to use __longSum() function instead.
See Apache JMeter Functions - An Introduction guide for more information on JMeter functions concept.

Generating function value within variable in Jmeter

I want to use the Random function within the variable in Jmeter for example
${demo_variable_g${__Random(1,4,)}}
I am extracting the values for demo_variable using regular expression extractor. I want to generate random number while using the extracted variable value. How do I do that?
The correct function would be:
${__V(demo_variable_g${__Random(1,4,)})}
From the __V() function documentation
For example, if one has variables A1,A2 and N=1:
${A1} - works OK
${A${N}} - does not work (nested variable reference)
${__V(A${N})} - works OK. A${N} becomes A1, and the __V function returns the value of A1
See Here’s What to Do to Combine Multiple JMeter Variables article for explanation and demos

SPSS- assigning mulitple numeric codes to one variable

I am trying to assign multiple codes to existing variables. I am using the syntax below, but it will only assign the first code entered for that hosp.id.number.
Syntax example:
Do if (hosp.id.number=9037) or (hosp.id.number=1058) or (hosp.id.number=11256).
Compute role_EM_communication=10.
Else if (hosp.id.number=9037.
Compute role_EM_communication=11.
End if.
Execute.
hosp.id.number needs to be coded 10 and 11, but it will only code it at 10. Anyway to rephrase so that SPSS will accept 2 or more codes for a variable such as hosp.id.number?
Your role_EM_communication variable is a single variable, but from what you are saying, I think you need it to be a set (for the same record, it could take on more than just one code). So you need to create n variables named role_EM_communication_1 to role_EM_communication_n, where n is the maximum number of codes you estimate will be possible for one record.
For your example, it would translate like this:
create the 2 variables:
vector role_EM_communication_ (2, f2.0).
do the first recode:
if any(hosp.id.number,9037,1058,11256) role_EM_communication_1=10.
very important - execute the recode
exe.
check if the first variable has data, and populate the second variable if true:
if miss(role_EM_communication_1) and any(hosp.id.number,9037) role_EM_communication_1=11.
if ~miss(role_EM_communication_1) and any(hosp.id.number,9037) role_EM_communication_2=11.
exe.

Is it possible to include jmeter variables in values obtained from CSV?

I have a csv file which contains a column named "query". One of the entires I have for query is /user/${id}/list/${list}.
What I would like to do is let jMeter overwrite the ${list} and ${id} variables in the query when it is passed to a HTTP Sampler with variable values already in use from previous steps in my test plan.
For example:
In test plan, create ${id} = 5 and ${list} = 10.
In test plan, open csv file that contains query string.
In test plan, perform use a HTTP Sampler. Path in query should be the query value passed from csv file.
3a. Jmeter should take query passed to sampler and replace ${id} and ${list} with the values stored to those variables within test plan (5 and 10).
Right now when I try this, the HTTP response comes back showing the request was made to /user/${id}/list/${list}, not /user/5/list/10.
Does anyone know how to force the substitution through jMeter?
Is it even possible?
I was able to figure this one out after a bit of head scratching.
JMeter allows you to overload variables (place references to variables within a variable) by using the __eval function.
To get around the issue, I left the csv file as is, with references to variables set. When I wanted to reference the query from the csv file and overload the variable placeholders with actual values I used ${__eval(${query})} - where query = the
Try to use __eval function instead:
/user/${__eval(${id})}/list/${__eval(${list})}
__eval function seems to be just your case.
