Don't include the autoincrement column in your insert statement and it should work fine.

Count the number of '?' in your insert statement. Are you trying to define one for the autoincrement column? The number of parameters to be bound should be one less than the number of fields in the table (since the database will populate the autoincrement field, you don't have to).

set the auto increment field to null
e.g.
suppose id is an auto increment field
insert into table(id,name) values(null,"aldsf");

if preparedstatement
insert into table(id,name) values(null,?);

pStmt.setString(1,"aldsf");
