@brief Compares the metadata of a library with the physical tables
@details Creates a series of output tables that show the differences between
metadata and physical tables.
Each output can be created with an optional prefix.

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](
https://www.linkedin.com/in/allanbowe) 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.
@param [in] libname= the metadata name of the library to be compared
@param [out] outlib=(work) The library in which to store the output tables.
@param [out] prefix=(metadiff) The prefix for the four tables created.
@version 9.3
