Hello,

Is there a table or view that can give me the list of all the tables in a schema and their counts, respectivily.

It wouldn't be possible to write a SQL on USER_TABLES or something and pass the table name as the variable, would it?

Thanks

Check user_tables.num_rows.
Be advised that, these values are not always correct and
* will be populated only after collecting stats
* may be outdated.
* anyone with proper access can set explicit values using SET_TABLE_STATS.

Search the forum for more information

Is this what you want?
SQL> var tab varchar2(100);
SQL> exec :tab := 'TEST';

PL/SQL procedure successfully completed.

SQL> select table_name, num_rows from user_tables where table_name = :tab;
TABLE_NAME                       NUM_ROWS
------------------------------ ----------
TEST                                   11

1 row selected.

Regards
Michel
