INNER JOIN

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

10 min read • Intermediate

INNER JOIN is an atomic SAS lesson inside PROC SQL. 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 INNER JOIN rather than on generic SAS syntax.

Topic-specific example

sas-04-03.sas
sas Try It Live 
proc sql; select o.id,u.name from work.orders o inner join work.users u on u.id=o.user_id; quit;
Edge case / engineering note

For INNER JOIN, 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.
