A complete shot in the dark, but try the alternative "go" sequence
i.e. \g rather than ;. The reason I suggest this is that perhaps the ;
is geting filtered out by the comint process? (N.B. This is a SWAG)

MySQL exits abnormally in Emacs

[Corey Foote]

Hello everyone,

I'm a newbie user to MySQL, and I'm trying to learn how to run an
interactive SQL session through Emacs. I'm using GNU Emacs 22.0 and
MySQL 5.0 under Windows XP.

After typing the following:

1. M-x sql-mysql
2. User: myusername RET
3. Password: mypassword RET
4. Database: mydatabase RET
5. Server: localhost RET

I type my query and press C-c C-c and get the following error:

select now();  C-c C-cnow()
2006-12-14 14:11:25

Process SQL exited abnormally with code 1

It gives the correct result, but the process "exits abnormally" and then
I can't type in any further queries without going through steps 1-5
again. It does not give me this problem when I'm using the terminal
window.

Also, nothing happens when I simply type my query and press RET. It
seems I have to type C-c C-c in order to get any results.

Any solutions you could offer would be most appreciated. I'd much
rather stay in Emacs to work with SQL, rather than having to jump back
and forth to the terminal window.

Thank you for your help,

Corey Foote

Where do you type C-c C-c? If it is in the process buffer (the one
where mysql is running), C-c C-c is bound to
`comint-interrupt-subjob', so it's no wonder that it gets interrupted.
In that buffer it's enough to press ENTER after queries:

select count(*) from mysql.user;
+----------+
| count(*) |
+----------+
|        5 |
+----------+

C-c C-c (`sql-send-paragraph') is used from a SQL buffer that you
associate with the inferior process (the subprocess) that is running
mysql.  For example, create a buffer in SQL mode (either setting it
with "M-x sql-mode" or visiting a .SQL file), and then do "M-x
sql-product-interactive", or choose the option "Start SQLi Session" in
the SQL menu.  That way you'll have a running mysql client in a buffer
associated with your SQL source buffer. Then you can write SQL code in
your source buffer and send it to the inferior process with C-c C-c.

Take a look at the file lisp/progmodes/sql.el.

Thanks for your reply to my posting. However, I think I didn't explain
the problem I'm having well enough. Please allow me to try to describe it
more clearly.

When I type queries into the process buffer and press enter, no
results are returned until I interrupt the process with C-c C-c. Only
when the process is interrupted are any results returned. The results
off all queries are then returned together and without any boxes being
drawn around them. For example, if I type into the process buffer the
following:

select now();RET

select count(*) from mysql.user;RET

No results are returned until I type C-c C-c in the process buffer at
which point the results are returned all at once and without
formatting:

  C-c C-cnow()
2006-12-15 22:15:55
count(*)
5

Process SQL exited abnormally with code 1

It would be nice to be able to get the results I need without having
to terminate the process in order to see them.

Thanks again,

How are you starting the process buffer? From a source buffer in
sql-mode, or directly running `sql-mysql'?

If you do C-c C-c from a sql-mode buffer attached to the process
buffer, do you get any results?

Hi,

I've been starting the process buffer by directly running sql-mysql,
but I also just tried doing it from a source buffer in sql-mode, and I
get the same result; No results show up until I go to the process
buffer and type C-c C-c.

When I do C-C C-c from a sql-mode buffer (after first setting SQLi
buffer to the process buffer), Emacs says, "sent string to buffer
*SQL*," but again no results show up until I go down to the
process buffer and type C-c C-c.

Are you passing the -n ("flush buffer after each query") option to
mysql? You can do it by configuring `sql-mysql-options'.
