How to Count Number of Tables and Views from Oracle and DB2

17 Oct , 2012 No Comments

Several days ago i had a project that made me had to do data migration from DB2 to Oracle.
For validity check, i had to count number of tables and views from DB2 before migrated and number of tables and views on Oracle after ive migrate it.

Okay enough chit-chat, this is my queries.
Count DB2’s number of tables

Select Count(*) from syscat.tables
where tabschema = 'YOUR_SCHEMA_NAME' 
AND type = 'T'

And this is how to count DB2’s View numbers

Select Count(*) from syscat.tables
where tabschema = 'YOUR_SCHEMA_NAME' 
AND type = 'V'

This is how to count number of tables from Oracle

select owner, count(*) from dba_tables
where owner = 'YOUR_OWNER_NAME'
group by owner

And this is how to count number of views from Oracle

select owner, count(*) from dba_views
where owner = 'YOUR_OWNER_NAME'
group by owner

Hope it will help others,
cheers (D)
