I am using korma in my project.

scknkkrer18:04:22

I have to go trough utf8mb4.

scknkkrer18:04:37

But how can I implement this ?

donaldball18:04:12

What problem are you running into?

tanzoniteblack18:04:27

@scknkkrer are you getting error messages? Or mucking up strings? Or...what's going on that is making it just "not work"

scknkkrer18:04:22

nope, I almost write any character in my language, except 3 of them.

scknkkrer18:04:12

writing ? instead of these characters.

scknkkrer18:04:31

:db “olexi?characterSetResult=utf8mb4&characterSet=utf8mb4&collation=utf8mb4_unicode_ci” :useUnicode true :characterEncoding “UTF-8"

scknkkrer18:04:49

I try with this.

seancorfield18:04:00

Also, what DB are you using and what version of that DB? (e.g., MySQL 5.5 doesn’t support full Unicode, even if you provide all the correct connection parameters)

scknkkrer18:04:16

Wait, connector or Database Server version ?

seancorfield18:04:24

Server version.

seancorfield18:04:15

But folks have asked for more details about your environment — which is good, basic debugging practice — what DB, what server version, what JDBC driver version, what does your db-spec look like, etc?

seancorfield18:04:11

I would also recommend creating a small self-contained correct example — per http://www.sscce.org — and put it on GitHub (or in a Gist) so folks can take a look at the whole (small!) code to help you debug things.

scknkkrer18:04:55

it’s 5.7.16

scknkkrer18:04:47

thanks, I will read after fix this.

scknkkrer18:04:47

[mysql/mysql-connector-java “5.1.26”]

scknkkrer18:04:03

[korma “0.4.0”] [org.clojure/java.jdbc “0.3.7"]

scknkkrer19:04:25

When I put this characters to my db direct, there is no problem.

scknkkrer19:04:35

only when I put it with clojure.

seancorfield19:04:01

I’ll repeat my — still unanswered — question: what does your db-spec look like?

seancorfield19:04:37

And, again, suggest you write a SSCCE without Korma, just with java.jdbc.

seancorfield19:04:01

That will be the easiest way for you to debug this.

scknkkrer19:04:17

:db “dbname?characterSetResult=utf8mb4&characterSet=utf8mb4&collation=utf8mb4_unicode_ci?characterEncoding=UTF-8” :useUnicode true :characterEncoding “UTF-8" :characterSet “utf8mb4” :collation “utf8mb4_unicode_ci”

seancorfield19:04:22

That’s not a valid db-spec for java.jdbc so I assume that’s what Korma expects and it’s doing something under the hood to create a db-spec for java.jdbc.

seancorfield19:04:50

Like I say, create a SSCCE without Korma, so you can verify what parameters you need in your db-spec with java.jdbc, to make this work.

seancorfield19:04:21

You may also want to check the docs for the mysql-connector-java library to see if there are fixes in more recent versions that will work with MySQL Server 5.7.16. We’re using 5.1.39 at work I think. We can’t use the 6.0.x driver since it doesn’t seem to work with MySQL 5.5 / 5.6 which we’re still on.

scknkkrer19:04:49

Thanks for your help.

scknkkrer19:04:06

one last question; isn’t there any problem while I read the data. It’s when I write.

seancorfield19:04:59

Is that a question? I’m not sure what you’re asking.
