If the table name is already quoted, this method will do nothing. A simple table name should contain the table name only without any schema prefix.
Null if the named table does not exist. The table name may contain schema name if any.

FYI: Used two DB shell sessions and a table with a serial field

Maybe someone facing this problem. Most of the features are still there but they have of course removed a bit

Drupal implements these with a table for mysql.
Specifically, lastInsertId only sometimes works.
Inserted a record into the table from each session then called currval. Details for this specific function can be found at Getting rid of the sequences table, using db_last_insert_id() instead of db_next_id() [#49836] | Drupal.org
