ACL Character Function – Include() Function

Welcome back future ACL data analyst. We continue with the series of post for Audit Command Language for beginner data analysts. The next character based function in audit command language is the Include function.

Just like any other function in the Audit Command Language, this is an equally important function. Just like the Exclude function, this function is most often used for the purposes of data cleansing. The difference between the two can be deduced by the names themselves. Nevertheless, to put it in context, there are cases where the requirements are such that only certain characters in the field may be required for a certain analysis. For instance, there may be account numbers in a ledger where alphabets are just added for identification purposes but for overall reconciliations, the actual account number is to be considered. In such cases, only numeric values are required to be ‘included’ in the final formatted data.

Syntax: Include(Data Field or string,<Characters to include>)

Example in a script to create a new field using Include Function

DELETE FIELD NEW_GENDER OK
DEFINE FIELD NEW_GENDER COMPUTED AS
Include(FIELD_1,’M’)

Example in a workspace to create a new field using Exclude Function

NEW_GENDER Computed
Include(FIELD_1,’M’)

The above examples are attempting to include only the character ‘M’ in the gender field in the existing table and create a new field. See the below screenshot for the result.

It really is as easy as it looks. There shouldn’t be any real challenges here for anyone and it is a nifty trick to be able to use to impress your first boss to help him/her with data cleansing. So keep an eye open for any such opportunities.

ACL Character Function – Exclude() Function

Greetings and welcome to the latest post in the series ‘Audit Command Language Tutorial‘ for Beginners. The next few posts are going to be dedicated to character functions as discussed in the last post. Each of the following posts will explore a character function in detail with an example. So let’s dive straight in.

The first of these functions is the Exclude function. A very important function for data cleansing purposes. Every so often there are certain special characters that get included in certain key fields in data sets. In order to ensure correct analysis on these key fields, it is required that these special characters be excluded from the field in order to normalize/standardize the data.

Syntax: Exclude(Data Field or string ,<Characters to exclude>)

Example in a script to create a new field using Exclude Function

DELETE FIELD NEW_GENDER OK
DEFINE FIELD NEW_GENDER COMPUTED AS
Exclude(FIELD_1,’M’)

Example in a workspace to create a new field using Exclude Function

New_GENDER                                Computed
EXCLUDE(FIELD_1,’M’)

Results from either of the above methods would be that any instance of the character ‘M’ will be removed from any relevant values in the column ‘Field_1’ when creating the new column ‘New_Gender’.

This is an easy enough function to use and apply in any project. The only thing to do is to identify the appropriate instance for implementation. Check out the video for a demo of the function :

This post and the subsequent entries should provide for considerable inputs for you to start playing around with data formatting efforts in your own projects.
