Hi
Can anyone help me?
I'm trying to put an index on a text column named invariant.
I tried this command :
alter table cinvariant add index (invariant);
I got this:
ERROR 1170: BLOB column 'invariant' used in key specification without a key
length
ok so I tried this
alter table cinvariant add index (invariant(375));
I got this:
ERROR 1089: Incorrect sub part key. The used key part isn't a string or the
used length is longer then the key part
i don't get it the length should be something around 2^16.
Please give me an advice!
Thanks in advance
dacian
