Seems SA checks if table already exist in all_tables system table...
and creates it only if it doesn't exist.
In my case...
SQL> select table_name from all_tables where
table_name='FUNZIONE_CALCOLO', returns:
TABLE_NAME
------------------------------
FUNZIONE_CALCOLO
SQL> select table_name from all_tables where table_name='TARIFFA';
no rows selected
instead :
SQL> desc FUNZIONE_CALCOLO
ERROR:
ORA-04043: object FUNZIONE_CALCOLO does not exist
SQL> desc TARIFFA
ERROR:
ORA-04043: object TARIFFA does not exist
-------------------------------------------
probably it is because I droped the table funzione_calcolo.
Is it regular that FUNZIONE_CALCOLO is in all_tables yet?
