I can try to fix that here. This crash seems to be happen when adding the 12000 table names into SynEdit's internal list. I guess you can live with it when Heidi does not highlight all of these 12000 table names in the editor, but let's say the first 1000 tables only.

Of course, i understand that this is not a usual problem but i like the program so much and i will be very glad if i could work with it with all my databases. smilesmilesmile

I spent one hour to find the place where table names are being added to the highlighter, with no luck yet. Damn I was sure it was TSynSQLSyn.TableNames. Will keep looking.

Thank you!!!

Fixed in r4817. Highlighter does no longer try to highlight tables when there are more than 1000.

YOU ARE THE BEST!!! I am gonna' try it out right away! :)

Hi there,

I have the same probleme here.
900 tables and about 600 Triggers.
Is it possible to skip highlighting for triggers?
Is there any reason to highlight them?
Maybe you could higlight the first 1000 items, or may increase this number?
thank you

The SynEdit guys fixed that slowness issue with many table names!

In my tests I simulated 50000 table names without a notifiable waiting time.

I merged the changes into HeidiSQL in r5111 so you can test yourself. I also removed the limitation to 1000 tables names now.

Highlighting works fine. Thank you

But, Everytime I try to do autocompletion using CTRL + SPACE Heidi executes an show create table for each table and a show create trigger too. in my case there are about 1600 show creates beeign executed.

That has nothing to do with highlighting, does it?

Well, if you're on a newer MySQL server, these SHOW CREATE queries should be fired as one big multi-statement with semicolons between each single one, are they?
