Database showing 0 B in size

jivory posted 2 years ago in General
I'm having an issue with a database showing up. I've used HeidiSQL for a while now, connecting to the same DBs. The last few days I've not been able to pull up a specific DB. My connection is the same, and other, smaller DBs still show up, but our 'large' DB does not. I'm unsure of the size, but I know it's sever Gig.
This issue only happens on my machine, and another co-worker's, both using Windows 7. Everyone else is either on Linux or a Mac, and they have no issues.

Has anyone ever seen this issue? I'm wondering if the DB reached a size limit that Windows cannot handle. This seems odd, but the only logical explanation right now.

Are you talking about the tree on the left, right besides the databases? Maybe send a link to a screenshot?

Could you say more exactly how big that db is? And, more important, what HeidiSQL revision you are using, and what server version it is.

I just thought you hit the 32 bit limit for some integer variable in HeidiSQL, but I also have a larger database with ~3gb in it, which does not have that problem.

I try running:
SELECT table_schema "Data Base Name", sum( data_length + index_length ) / 1024 / 1024 "Data Base Size in MB"
FROM information_schema.TABLES GROUP BY table_schema ;
to get the size, and it fails with a 2013 error, so I'm not sure the exact size, but I want to say somewhere around 20G.

I tried another program, SQL Wave 6, and when I try to load this DB, it freezes up (Not Responding), but the other DBs work just fine.

Is there some setting in my.ini I could change to increase size or cache? Something like that, that would be killing the connection trying to connect to this specific DB?

And yes, I'm talking about the tree on the left. It shows not tables, and says 0 B. But I know that my XAMPP connects and uses the DB, because my local environment work, and I can even make queries within HeidiSQL, it just won't show me the tables or info.

You said the IS query returns with a "2013 error". What's the exact error message? Perhaps there is a hint to what's going on here.

I don't get any such error using the SQL Wave 6, it just freezes, so at least HeidiSQL gives me an error to help try and figure it out haha

There must be some broken file in your database directory. You should try to run "REPAIR TABLE yourtable" for all of your tables.

Thanks, I'll give that a try. I downloaded a trial of Navicat, and it loads everything just fine, so maybe it is a size limit or something that Windows isn't liking.

I am having this same issue.
Looking at the console when trying to select a DB, it shows this:

/* Entering session "SESSIONNAME" */

/* [SESSIONNAME] Connecting to HOSTNAME/IP via MySQL (TCP/IP), username USERNAME, using password: Yes ...*/

/* [SESSIONNAME] Connected. Thread-ID: 4951 */

[SESSIONNAME] SHOW STATUS;
[SESSIONNAME] SHOW VARIABLES;
[SESSIONNAME] SHOW DATABASES;

/* [SESSIONNAME] Connection to HOSTNAME/IP closed at YYYY-MM-DD HH-MM-SS */

My solution was, making work purchase Navicat, which loads my db just fine.

I'm able to load a db that's 1.4GB, but our large one that's around 16+GB, is the one that has issues, doesn't show anything and displays 0B.

Maybe it was something with an update? It worked great a few months ago, I've kept regular updates, and just stopped working one day.

I have not tried on Mac or Linux, so it still could be some Windows issue.
