;;; Commentary:

;; Please send bug reports and bug fixes to the mailing list at
;; help-gnu-emacs@gnu.org.  If you want to subscribe to the mailing
;; list, see the web page at
;; http://lists.gnu.org/mailman/listinfo/help-gnu-emacs for

;; This file provides a sql-mode and a sql-interactive-mode.  The
;; original goals were two simple modes providing syntactic
;; highlighting.  The interactive mode had to provide a command-line
;; history; the other mode had to provide "send region/buffer to SQL
;; interpreter" functions.  "simple" in this context means easy to
;; use, easy to maintain and little or no bells and whistles.  This
;; has changed somewhat as experience with the mode has accumulated.

;; Support for different flavors of SQL and command interpreters was
;; available in early versions of sql.el.  This support has been
;; extended and formalized in later versions.  Part of the impetus for
;; the improved support of SQL flavors was borne out of the current
;; maintainers consulting experience.  In the past twenty years, I
;; have used Oracle, Sybase, Informix, MySQL, Postgres, and SQLServer.
;; On some assignments, I have used two or more of these concurrently.

;; If anybody feels like extending this sql mode, take a look at the
;; above mentioned modes and write a sqlx-mode on top of this one.  If
;; this proves to be difficult, please suggest changes that will
;; facilitate your plans.  Facilities have been provided to add
;; products and product-specific configuration.

;; sql-interactive-mode is used to interact with a SQL interpreter
;; process in a SQLi buffer (usually called `*SQL*').  The SQLi buffer
;; is created by calling a SQL interpreter-specific entry function or
;; sql-product-interactive.  Do *not* call sql-interactive-mode by
;; itself.

;; The list of currently supported interpreters and the corresponding
;; entry function used to create the SQLi buffers is shown with
;; `sql-help' (M-x sql-help).

;; Since sql-interactive-mode is built on top of the general
;; command-interpreter-in-a-buffer mode (comint mode), it shares a
;; common base functionality, and a common set of bindings, with all
;; modes derived from comint mode.  This makes these modes easier to
;; use.

;; sql-mode can be used to keep editing SQL statements.  The SQL
;; statements can be sent to the SQL process in the SQLi buffer.

;; For documentation on the functionality provided by comint mode, and
;; the hooks available for customizing it, see the file `comint.el'.

;; Hint for newbies: take a look at `dabbrev-expand', `abbrev-mode', and
;; `imenu-add-menubar-index'.

;;; Requirements for Emacs 19.34:

;; If you are using Emacs 19.34, you will have to get and install
;; the file regexp-opt.el
;; <URL:ftp://ftp.ifi.uio.no/pub/emacs/emacs-20.3/lisp/emacs-lisp/regexp-opt.el>
;; and the custom package
;; <URL:http://www.dina.kvl.dk/~abraham/custom/>.

;;; Bugs:

;; sql-ms now uses osql instead of isql.  Osql flushes its error
;; stream more frequently than isql so that error messages are
;; available.  There is no prompt and some output still is buffered.
;; This improves the interaction under Emacs but it still is somewhat
;; awkward.

;; Quoted identifiers are not supported for highlighting.  Most
;; databases support the use of double quoted strings in place of
;; identifiers; ms (Microsoft SQLServer) also supports identifiers
;; enclosed within brackets [].

;;; Product Support:

;; To add support for additional SQL products the following steps
;; must be followed ("xyz" is the name of the product in the examples
;; below):

;; 1) Add the product to the list of known products.

;;     (sql-add-product 'xyz "XyzDB"
;;     	                '(:free-software t))

;; 2) Define font lock settings.  All ANSI keywords will be
;;    highlighted automatically, so only product specific keywords
;;    need to be defined here.

;;     (defvar my-sql-mode-xyz-font-lock-keywords
;;       '(("\\b\\(red\\|orange\\|yellow\\)\\b"
;;          . font-lock-keyword-face))
;;       "XyzDB SQL keywords used by font-lock.")

;;     (sql-set-product-feature 'xyz
;;                              :font-lock
;;                              'my-sql-mode-xyz-font-lock-keywords)

;; 3) Define any special syntax characters including comments and
;;    identifier characters.

;;     (sql-set-product-feature 'xyz
;;                              :syntax-alist ((?# . "_")))

;; 4) Define the interactive command interpreter for the database
;;    product.

;;     (defcustom my-sql-xyz-program "ixyz"
;;       "Command to start ixyz by XyzDB."
;;       :type 'file
;;       :group 'SQL)
;;
;;     (sql-set-product-feature 'xyz
;;                              :sqli-program 'my-sql-xyz-program)
;;     (sql-set-product-feature 'xyz
;;                              :prompt-regexp "^xyzdb> ")
;;     (sql-set-product-feature 'xyz
;;                              :prompt-length 7)

;; 5) Define login parameters and command line formatting.

;;     (defcustom my-sql-xyz-login-params '(user password server database)
;;       "Login parameters to needed to connect to XyzDB."
;;       :type 'sql-login-params
;;       :group 'SQL)
;;
;;     (sql-set-product-feature 'xyz
;;                              :sqli-login 'my-sql-xyz-login-params)

;;     (defcustom my-sql-xyz-options '("-X" "-Y" "-Z")
;;       "List of additional options for `sql-xyz-program'."
;;       :type '(repeat string)
;;       :group 'SQL)
;;
;;     (sql-set-product-feature 'xyz
;;                              :sqli-options 'my-sql-xyz-options))

;;     (defun my-sql-comint-xyz (product options)
;;       "Connect ti XyzDB in a comint buffer."
;;
;;         ;; Do something with `sql-user', `sql-password',
;;         ;; `sql-database', and `sql-server'.
;;         (let ((params options))
;;           (if (not (string= "" sql-server))
;;              (setq params (append (list "-S" sql-server) params)))
;;           (if (not (string= "" sql-database))
;;               (setq params (append (list "-D" sql-database) params)))
;;           (if (not (string= "" sql-password))
;;               (setq params (append (list "-P" sql-password) params)))
;;           (if (not (string= "" sql-user))
;;               (setq params (append (list "-U" sql-user) params)))
;;           (sql-comint product params)))
;;
;;     (sql-set-product-feature 'xyz
;;                              :sqli-comint-func 'my-sql-comint-xyz)

;; 6) Define a convenience function to invoke the SQL interpreter.

;;     (defun my-sql-xyz (&optional buffer)
;;       "Run ixyz by XyzDB as an inferior process."
;;       (interactive "P")
;;       (sql-product-interactive 'xyz buffer))

;;; To Do:

;; Improve keyword highlighting for individual products.  I have tried
;; to update those database that I use.  Feel free to send me updates,
;; or direct me to the reference manuals for your favorite database.

;; When there are no keywords defined, the ANSI keywords are
;; highlighted.  ANSI keywords are highlighted even if the keyword is
;; not used for your current product.  This should help identify
;; portability concerns.

;; Add different highlighting levels.

;; Add support for listing available tables or the columns in a table.

Without an entry in this list a product will not be properly
highlighted and will not support `sql-interactive-mode'.

Each element in the list is in the following format:

 \(PRODUCT FEATURE VALUE ...)

where PRODUCT is the appropriate value of `sql-product'.  The
product name is then followed by FEATURE-VALUE pairs.  If a
FEATURE is not specified, its VALUE is treated as nil.  FEATURE
may be any one of the following:

 :name                  string containing the displayable name of
                        the product.

 :free-software         is the product Free (as in Freedom) software?

 :font-lock             name of the variable containing the product
                        specific font lock highlighting patterns.

 :sqli-program          name of the variable containing the product
                        specific interactive program name.

 :sqli-options          name of the variable containing the list
                        of product specific options.

 :sqli-login            name of the variable containing the list of
                        login parameters (i.e., user, password,
                        database and server) needed to connect to
                        the database.

 :sqli-comint-func      name of a function which accepts no
                        parameters that will use the values of
                        `sql-user', `sql-password',
                        `sql-database', `sql-server' and
                        `sql-port' to open a comint buffer and
                        connect to the database.  Do product
                        specific configuration of comint in this
                        function.

 :list-all              Command string or function which produces
                        a listing of all objects in the database.
                        If it's a cons cell, then the car
                        produces the standard list of objects and
                        the cdr produces an enhanced list of
                        objects.  What \"enhanced\" means is
                        dependent on the SQL product and may not

;; While there are international and American standards for SQL, they
;; are not followed closely, and most vendors offer significant
;; capabilities beyond those defined in the standard specifications.

;; SQL mode provides support for highlighting based on the product.  In
;; addition to highlighting the product keywords, any ANSI keywords not
;; used by the product are also highlighted.  This will help identify
;; keywords that could be restricted in future versions of the product
;; or might be a problem if ported to another product.

;; To reduce the complexity and size of the regular expressions
;; generated to match keywords, ANSI keywords are filtered out of
;; product keywords if they are equivalent.  To do this, we define a
;; function `sql-font-lock-keywords-builder' that removes any keywords
;; that are matched by the ANSI patterns and results in the same face
;; being applied.  For this to work properly, we must play some games
;; with the execution and compile time behavior.  This code is a
;; little tricky but works properly.

;; When defining the keywords for individual products you should
;; include all of the keywords that you want matched.  The filtering
;; against the ANSI keywords will be automatic if you use the
;; `sql-font-lock-keywords-builder' function and follow the
;; implementation pattern used for the other products in this file.

Other non-free SQL implementations are also supported:

But we urge you to choose a free implementation instead of these.

You can also use \\[sql-product-interactive] to invoke the
interpreter for the current `sql-product'.

Once you have the SQLi buffer, you can enter SQL statements in the
buffer.  The output generated is appended to the buffer and a new prompt
is generated.  See the In/Out menu in the SQLi buffer for some functions
that help you navigate through the buffer, the input history, etc.

If you have a really complex SQL statement or if you are writing a
procedure, you can do this in a separate buffer.  Put the new buffer in
`sql-mode' by calling \\[sql-mode].  The name of this buffer can be
anything.  The name of the major mode is SQL.

In this SQL buffer (SQL mode), you can send the region or the entire
buffer to the interactive SQL buffer (SQLi mode).  The results are

See `sql-help' on how to create SQLi buffers.

Customization: Entry to this mode runs the `sql-mode-hook'.

When you put a buffer in SQL mode, the buffer stores the last SQLi
buffer created as its destination in the variable `sql-buffer'.  This
will be the buffer \\[sql-send-region] sends the region to.  If this
SQLi buffer is killed, \\[sql-send-region] is no longer able to
determine where the strings should be sent to.  You can set the

For information on how to create multiple SQLi buffers, see
`sql-interactive-mode'.

Note that SQL doesn't have an escape character unless you specify
one.  If you specify backslash as escape character in SQL,
you must tell Emacs.  Here's how to do that in your `~/.emacs' file:

  "Major mode to use a SQL interpreter interactively.

Do not call this function by yourself.  The environment must be
initialized by an entry function specific for the SQL interpreter.
See `sql-help' for a list of available entry functions.

\\[comint-send-input] after the end of the process' output sends the
text from the end of process to the end of the current line.
\\[comint-send-input] before end of process output copies the current
line minus the prompt to the end of the buffer and sends it.
\\[comint-copy-old-input] just copies the current line.
Use \\[sql-accumulate-and-indent] to enter multi-line statements.

If you want to make multiple SQL buffers, rename the `*SQL*' buffer
using \\[rename-buffer] or \\[rename-uniquely] and start a new process.
See `sql-help' for a list of available entry functions.  The last buffer
created by such an entry function is the current SQLi buffer.  SQL
buffers will send strings to the SQLi buffer current at the time of
their creation.  See `sql-mode' for details.

Sample session using two connections:

1. Create first SQLi buffer by calling an entry function.
2. Rename buffer \"*SQL*\" to \"*Connection 1*\".
3. Create a SQL buffer \"test1.sql\".
4. Create second SQLi buffer by calling an entry function.
5. Rename buffer \"*SQL*\" to \"*Connection 2*\".
6. Create a SQL buffer \"test2.sql\".

Now \\[sql-send-region] in buffer \"test1.sql\" will send the region to
buffer \"*Connection 1*\", \\[sql-send-region] in buffer \"test2.sql\"
will send the region to buffer \"*Connection 2*\".

If you accidentally suspend your process, use \\[comint-continue-subjob]
to continue it.  On some operating systems, this will not work because
the signals are not supported.

\\{sql-interactive-mode-map}
Customization: Entry to this mode runs the hooks on `comint-mode-hook'
and `sql-interactive-mode-hook' (in that order).  Before each input, the
hooks on `comint-input-filter-functions' are run.  After each SQL
interpreter output, the hooks on `comint-output-filter-functions' are
run.

Variable `sql-input-ring-file-name' controls the initialization of the
input ring history.

Variables `comint-output-filter-functions', a hook, and
`comint-scroll-to-bottom-on-input' and
`comint-scroll-to-bottom-on-output' control whether input and output
cause the window to scroll to the end of the buffer.

If you want to make SQL buffers limited in length, add the function
`comint-truncate-buffer' to `comint-output-filter-functions'.

Here is an example for your .emacs file.  It keeps the SQLi buffer a
certain length.

\(add-hook 'sql-interactive-mode-hook
    \(function (lambda ()
        \(setq comint-output-filter-functions 'comint-truncate-buffer))))

Here is another example.  It will always put point back to the statement
you entered, right above the output it created.
