Get all information schema from Database tables
Information schema views provide an internal,
system table-independent view of the SQL Server metadata.
Examples:
select * from INFORMATION_SCHEMAcolumns as table1 INNER JOIN INFORMATION_SCHEMA.tavble2
ON table1.TABLE_SCHEMA = table1 AND table2.TABLE_NEME =table1.TABLE_NAEM
WHERE table1.TABLE_TYPE ='base table'.
