    <p>I think you're quite right, the reason that sql-set-sqli-buffer is not finding a suitable SQLi buffer is because it takes the product subtype of the SQL-mode buffer into account when walking through the list of open buffers. </p> <p>Here's the code for the buffer testing from my copy of sql.el, which shipped with my emacs ( version - GNU emacs 24.2.1</p> <pre><code>(defun sql-find-sqli-buffer (&amp;optional product connection) "Returns the name of the current default SQLi buffer or nil. In order to qualify, the SQLi buffer must be alive, be in `sql-interactive-mode' and have a process." (let ((buf sql-buffer) (prod (or product sql-product))) (or ;; Current sql-buffer, if there is one. (and (sql-buffer-live-p buf prod connection) buf) ;; Global sql-buffer (and (setq buf (default-value 'sql-buffer)) (sql-buffer-live-p buf prod connection) buf) ;; Look thru each buffer (car (apply 'append (mapcar (lambda (b) (and (sql-buffer-live-p b prod connection) (list (buffer-name b)))) (buffer-list))))))) </code></pre> <p>the two values used to primarily used to test eligibility are a buffer and a symbol identifying the product type. This symbol is passed in as an argument, or defaults to the value of sql-product. It appears that sql-product, unless set in some other way is defaulted to 'ansi, which is why your editing buffer is SQL[ANSI].</p> <p>You should try setting the product type in this buffer (e.g. with <code>M-x sql-set-product</code>) before trying to associate a SQLi buffer with the query buffer. If you want the default to always be 'mysql' you can set this in your init file, or customize it using <code>M-x customize-variable</code></p> <p>SQL-mode is quite order dependent on having the buffer set up with the right local variables in order to have a working associated iSQL session. </p> <p>A typical sequence I use to initiate an iSQL buffer with a query in another buffer I am already editing is as follows</p> <ol> <li>Switch to a buffer with the SQL text in it , by visiting a file perhaps, or using <code>C-x b</code> to create a temporary buffer. </li> <li>Set this buffer to be in the correct SQL type, with <code>M-x sql-set-product</code> and then entering a known type , such as "mysql" at the prompt.</li> <li>Hitting <code>C-c &lt;TAB&gt;</code> (bound to <code>sql-product-interactive</code>) to switch to an iSQL buffer associated to this buffer, potentially by locating or creating an new comint process</li> </ol> <p>It is probably worth reading the output of the <code>M-x sql-help</code> command. The documentation for SQL-mode is very light. I've figured out what little I know about it mostly from reading the source.</p>

    1. COThanks for the answer. I used to be able to just M-x sql-mode on a buffer I'd create with C-x b, and it would do the right thing. Now I have to M-x sql-mode RET M-x sql-set-product RET "postgres" RET. Presumably sql-find-sqli-buffer code changed in Emacs 24.

    2. COActually, that still gives me a "No SQL process started" error in the mini-buffer when I try to C-c C-c. :/

    3. COeven with a sql-postgres SQLi buffer already running? I think SQL mode has perhaps changed a bit for emacs 24, because I've returned to using a little, after a while away, and it does seem a bit crankier. Does my 1-2-3 example not work for you either (substituting postgres for mysql) ?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
