# Lowest

**Lowest**

Returns lowest non-null value from the list of int values. \
@param default (optional), Type int. If provided none of the input values are non-null, returns default, \
Input must be a number or list of numbers.

This function is helpful when a user wants to get the lowest value from a dataset (or set of column values).

### Example 1: 

Step 1: Create an empty **lowest\_example\_1** using AIOps studio as shown in the below screenshot.

Step 2: Add the following pipeline code/commands into the above-created pipeline as shown in the below screenshot:

You can copy the below code into your pipeline and execute that in your environment.\
\
\&#xNAN;*`##### This pipeline creates a list of rows with various numbers (int values) for various`* \
*`##### ids using AIOps studio.`*\
\
*`##### RDA function lowest is used to demo this example. In this pipeline, each row added`*\
*`##### has three columns with various numerical values. Pipeline uses RDA dm function`* \
*`##### lowest to pick the lowest value from set of values and prints that value`*\
*`##### for each row/id.`* \
\
*`@dm:empty`* \
*`--> @dm:addrow id = 'a1' & x = 10 & y = 3 & z = 9`*\
*`--> @dm:addrow id = 'a2' & x = 1 & y = 13 & z = 4`*\
*`--> @dm:addrow id = 'a3' & x = 7 & y = 3  & z = 3`*\
*`--> @dm:addrow id = 'a4' & x = 4 & y = -1 & z = 9`*\
*`--> @dm:map to = "MIN_VALUE" & from = "x,y,z" & func = 'lowest'`*<br>

\
Step 3: Click verify button to make sure syntax and pipeline code is correct (as shown below)

Step 4:  Click execute button and execute the pipeline. RDA will execute the pipeline without any errors (as shown below)

Step 5: RDA uses the dm function 'lowest' to select the 'lowest' numerical number (or value) from the dataset and map that to variable "MIN\_VALUE" and prints the output for each dataset (or row) as shown in the following screenshot.

![Lowest value is printed for each dataset in the MIN\_VALUE](/files/-Me8V5L7qD0PoNqS0yZY)

Similarly, dm: function 'lowest' can be used to select the lowest value(s) from the selected dataset.
