Hello.
If you want all records with item=1 to be at the beginning and
sorted in a random order you can use this query:
select * from tablea order by if(item=1,0,1), rand();

This is not going to work. If you are using MySQLCommandBuilder, then the
auto-generated ID will be pulled back for you (basically because it does a
select last_insert_id() internally). Or you can issue a select
last_insert_id() manually to determine the last generated id.

OK, I'm bad - I have curly quotes in my db that I failed to eliminate
prior to the insert. Now that they're in there, is there a way to
replace them with straight quotes? Everything I try fails to find them.

The REPLACE() function would do it if using the Character Mapping in
Windows.
UPDATE tbl_Name SET col1 = REPLACE(col1,'','')

They are ALT+0147 and ALT+0148 in Windows Character Map (charmap.exe)
