I'm just going to go with option E and hope for the best. As long as it doesn't generate a syntax error, I'm happy. Who needs to understand the intricacies of table inheritance, anyway?

Haha, this is a classic case of 'off-by-one' error. The 'INSERT' statement is missing the column names, so option C is the right answer. Better double-check your SQL, folks!

So, the correct answer is option C, the 'INSERT' statement generates an error.

Wait, 'CREATE TABLE log_01 () INHERITS (log);'? Isn't that supposed to be 'CREATE TABLE log_01 INHERITS (log);'? I think option B is the correct answer here.

Yes, the second 'CREATE TABLE' statement should be 'CREATE TABLE log_01 INHERITS (log);'. Option B makes sense.

I'm not sure, but I think the INSERT statement might cause an error.

I agree with Elden, the SELECT statement should return 1 row.

The 'CREATE TABLE log_01 () INHERITS (log);' statement looks good to me. The 'SELECT * FROM log;' should return the row we just inserted, so I'm going with option E.
