Use the queries to find database tables for an owner (namespace/schema), tables containing certain phrases, all columns in a table, or column containing a certain phrase.
<pre>
-- All tables for an owner (prefix before table name)
SELECT owner, table_name FROM all_tables where owner = 'PO';
-- Find table names
SELECT owner, table_name FROM all_tables where Table_Name like '%INVOICE%INTER%' order by Owner, Table_Name
SELECT owner, table_name FROM all_tables where lower(Table_Name) like '%pos_shipping_addresses%' order by Owner, Table_Name
-- Find column names (along with data type and length/size)
SELECT table_name, column_name, data_type, data_length from dba_tab_columns where lower(column_name) like '%ship%' and upper(table_name) = 'PO_HEADERS_INTERFACE'
