Documenting Integrity Constraints
Overview
To view the descriptor portion of your data, including
the integrity constraints that you have placed on a data set, you
can use the CONTENTS statement in the DATASETS procedure.
|
General form, DATASETS
procedure with the CONTENTS statement:
PROC DATASETS LIB=libref <NOLIST>;
CONTENTS
DATA=SAS-data-set;
QUIT;
libref
is the library in which
the data set is stored.
NOLIST
suppresses the directory
listing.
SAS-data-set
is the name of the
data set that you want information about.
|
Note: The CONTENTS statement in
the DATASETS procedure results in the same information as the CONTENTS
procedure.
Example
The following code displays
information about the Capinfo data set, including the integrity constraints
that were added to this data set in the last example. Notice that
the NOLIST option is used here to suppress the listing of all data
sets in the Work library. With this option, only the information for
the Capinfo data set is listed.
proc datasets nolist; contents data=capinfo; quit;
Only the integrity constraints
portion of the output is shown below.
