Usage:

%* create (and assign) a library for testing purposes ;
%mm_createlibrary(
  libname=My Temp Library,
  libref=XXTEMPXX,
  tree=/User Folders/&sysuserid,
  directory=%sysfunc(pathname(work))
)

%* create some tables;
data work.table1 table2 table3;
  a=1;b='two';c=3;
run;

%* register the tables;
proc metalib;
  omr=(library="My Temp Library");
  report(type=detail);
  update_rule (delete);
run;

%* modify the tables;
proc sql;
drop table table3;
alter table table2 drop c;
alter table table2 add d num;

%* run the macro;
%mm_getlibmetadiffs(libname=My Temp Library)

%* delete the library ;
%mm_deletelibrary(name=My Temp Library)

The program will create four output tables, with the following structure (and example data):

&prefix.added

name:$32. metaID:$17. SAStabName:$32.
DATA1

&prefix.deleted

name:$32. metaID:$17. SAStabName:$32.
TABLE3 A5XLSNXI.BK0001HO TABLE3

&prefix.updated

tabName:$32. tabMetaID:$17. SAStabName:$32. metaName:$32. metaID:$17. sasname:$32. metaType:$16. change:$64.
TABLE2 A5XLSNXI.BK0001HN TABLE2 c A5XLSNXI.BM000MA9 c Column Deleted
d d Column Added

&prefix.meta

Label1:$28. cValue1:$1. nValue1:D12.3
Total tables analyzed 4 4
Tables to be Updated 1 1
Tables to be Deleted 1 1
Tables to be Added 1 1
Tables matching data source 1 1
Tables not processed 0 0

If you are interested in more functionality like this (checking the health of SAS metadata and your SAS 9 environment) then do contact Allan Bowe for details of our SAS 9 Health Check service.

Our system scan will perform hundreds of checks to identify common issues, such as dangling metadata, embedded passwords, security issues and more.

Parameters
[in]libname=the metadata name of the library to be compared
[out]outlib=(work)The library in which to store the output tables.
[out]prefix=(metadiff)The prefix for the four tables created.
