Connecting MyISAM and InnoDB?

Databases
1

I’m not sure but I haven’t done this before.

Let say I have ,

Table A (MyISAM)
Table B (InnoDB)

I want to insert a foreign key into Table B referencing Table A primary index.

Is this possible?

If not should I convert Table A to innoDB?

myisam is necessary if you want to use fulltext indexing (or geolocation, if i recall correctly)

or if you’re tuning an app for massive read and infrequent update

otherwise, yes, make it innodb, because the FK won’t work otherwise

thanks

I can’t believed the InnoDB is not supported by my web hosting.

Is there an alternative for the InnoDB engine?

5

not that would do you any good

there is, however, an alternative for your web hosting

:slight_smile:

Can you name it? what engine is a good alternative for InnoDB?

thanks in advanced.

there are many different types of engines…

my point was, if your host doesn’t support innodb, what are the chances that one of these other engines will be supported?

not very likely, would be my guess

So what do you think the reason they don’t support it r937?
Because I asked them the reason but they don’t let me know.

it would be sheer speculation on my part, and probably not very complimentary

for the time being, make both of your tables myisam

performance should be fine, the only thing you will miss is automatic enforcement of relational integrity constraints

Thanks again r937

I’ll do that.
