I'm a novice to MySQL and am currently facing the following difficulty.
I'm trying to update a table with a row of data the primary key of which is
an ID which I believe is an auto incrementing serial number.  My first
question is how to check if this is the case.

Secondly while trying to insert such a row leaving out this column mySql is
inserting the row at ID 0 (the previous ID's in the table are from 1 to 9),
but then will not take further inserts.

Thanks for any help available.
