-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, all --
Having learned a bit about indexes, I have tried to practice a bit. So far things work for my char(20) fields, but I have a problem with a tinyblob. To wit: create table ccards ( # ID number id smallint not null default 0 auto_increment primary key , type smallint not null , # references ccardtypes.id name char(40) not null , # name as on card number tinytext not null , # card number expdate date not null , # expiration date hashsum tinyblob not null , # hash of the card: have we seen this one? index (hashsum) # for quick lookups ) ; Whenever I try this with the index, I get ERROR 1170 at line 49: BLOB column 'hash' used in key specification without a key length I don't know where the key length needs to be specified; I tried hashsum tinyblob(255) not null but that puked at the create stage :-) TIA & HAND & Happy Holidays mysql query, :-D - -- David T-G * There is too much animal courage in (play) [EMAIL PROTECTED] * society and not sufficient moral courage.
