Indexes in SAS

Learn Indexes in SAS in SAS through the exact construct, a dedicated example, a boundary case, and a mastery check.

12 min read • Advanced

Indexes in SAS is an atomic SAS lesson inside Data Access & Production. The example uses the specific syntax, command, API, instruction, or language rule named by this lesson.

Study the construct itself, then change one relevant input and predict the result before running it. That keeps this lesson focused on Indexes in SAS rather than on generic SAS syntax.

Topic-specific example

sas-08-08.sas
sas Try It Live 
proc datasets library=work; modify users; index create email / unique; quit;
Edge case / engineering note

For Indexes in SAS, inspect the SAS log as well as the output data set; type conversion, missing values, and BY-group ordering can change results without stopping execution.
