MPE_DATASTATUS_LIBS

The MPE_DATASTATUS_LIBS table captures frequently changing SAS library attributes such as size (if filesystem based) and the number of tables.

To trigger a scan, see the Refresh Data Catalog instructions.

Columns

• TX_FROM num: SCD2 open datetime
• 🔑 TX_TO num: SCD2 close datetime
• 🔑 LIBREF char(8): SAS Libref (8 chars)
• LIBSIZE num: The size of the library (in bytes), displayed with the SIZEKMG. format. Only applicable to BASE engine libraries.
• TABLE_CNT num: The number of tables in the library.
• CATALOG_CNT num: The number of SAS Catalogs in the library (from dictionary.catalogs).

Refresh Process

This table is populated by the mpe_refreshtables macro when a FULL library refresh is performed (all tables). It does not change when a single table is refreshed.

• LIBSIZE is the sum of filesize across the library members in dictionary.tables - hence it is only applicable to BASE (filesystem) engines. For SQL Server libraries, filesize is not available and row counts are instead taken from sys.partitions via pass-through
• TABLE_CNT is the count of tables in the library
