FILESYSTEMID

FIXED(5)

File system identification of the root page (FILESYSTEMID returns the index of the database internal file system/converter the file is stored in. A FILESYSTEMID of 0 means that the file is stored in the default file system/converter.)

CHAR(20)

File status (OK | DELETED | BAD | READ ONLY | UNKNOWN)

Space that is occupied by index pages of the file (KB)

NULL, if the file has no index pages or if TREEINDEXSIZE has not yet been determined

TREELEAVESSIZE

FIXED(20)

Space that is occupied by the leaf pages of the file (KB)

NULL, if TREELEAVESIZE has not yet been determined

LOBSIZE

FIXED(20)

Space that is occupied by LOB values of the table (KB)

0, if the file is not a table

NULL, if LOBSIZE has not yet been determined

CLUSTERED

CHAR(3)

Specifies whether data pages of the file are considered for storage in clusters (YES | NO)
