  35
  36 ;; This file provides a sql-mode and a sql-interactive-mode.  The
  37 ;; original goals were two simple modes providing syntactic
  38 ;; highlighting.  The interactive mode had to provide a command-line
  39 ;; history; the other mode had to provide "send region/buffer to SQL
  40 ;; interpreter" functions.  "simple" in this context means easy to
  41 ;; use, easy to maintain and little or no bells and whistles.  This
  42 ;; has changed somewhat as experience with the mode has accumulated.
  43
  44 ;; Support for different flavors of SQL and command interpreters was
  45 ;; available in early versions of sql.el.  This support has been
  46 ;; extended and formalized in later versions.  Part of the impetus for
  47 ;; the improved support of SQL flavors was borne out of the current
  48 ;; maintainers consulting experience.  In the past twenty years, I
  49 ;; have used Oracle, Sybase, Informix, MySQL, Postgres, and SQLServer.
  50 ;; On some assignments, I have used two or more of these concurrently.
  51
  52 ;; If anybody feels like extending this sql mode, take a look at the
  53 ;; above mentioned modes and write a sqlx-mode on top of this one.  If
  54 ;; this proves to be difficult, please suggest changes that will
  55 ;; facilitate your plans.  Facilities have been provided to add
  56 ;; products and product-specific configuration.
  57
  58 ;; sql-interactive-mode is used to interact with a SQL interpreter
  59 ;; process in a SQLi buffer (usually called `*SQL*').  The SQLi buffer
  60 ;; is created by calling a SQL interpreter-specific entry function or
  61 ;; sql-product-interactive.  Do *not* call sql-interactive-mode by
  62 ;; itself.
  63
  64 ;; The list of currently supported interpreters and the corresponding
  65 ;; entry function used to create the SQLi buffers is shown with
  66 ;; `sql-help' (M-x sql-help).
  67
  68 ;; Since sql-interactive-mode is built on top of the general
  69 ;; command-interpreter-in-a-buffer mode (comint mode), it shares a
  70 ;; common base functionality, and a common set of bindings, with all
  71 ;; modes derived from comint mode.  This makes these modes easier to
  72 ;; use.
  73
  74 ;; sql-mode can be used to keep editing SQL statements.  The SQL
  75 ;; statements can be sent to the SQL process in the SQLi buffer.
  76
  77 ;; For documentation on the functionality provided by comint mode, and
  78 ;; the hooks available for customizing it, see the file `comint.el'.
  79
  80 ;; Hint for newbies: take a look at `dabbrev-expand', `abbrev-mode', and
  81 ;; `imenu-add-menubar-index'.
  82
  83 ;;; Bugs:
  84
  85 ;; sql-ms now uses osql instead of isql.  Osql flushes its error
  86 ;; stream more frequently than isql so that error messages are
  87 ;; available.  There is no prompt and some output still is buffered.
  88 ;; This improves the interaction under Emacs but it still is somewhat
  89 ;; awkward.
  90
  91 ;; Quoted identifiers are not supported for highlighting.  Most
  92 ;; databases support the use of double quoted strings in place of
  93 ;; identifiers; ms (Microsoft SQLServer) also supports identifiers
  94 ;; enclosed within brackets [].
  95
  96 ;;; Product Support:
  97
  98 ;; To add support for additional SQL products the following steps
  99 ;; must be followed ("xyz" is the name of the product in the examples
 100 ;; below):
 101
 102 ;; 1) Add the product to the list of known products.
 103
 104 ;;     (sql-add-product 'xyz "XyzDB"
 105 ;;                      '(:free-software t))
 106
 107 ;; 2) Define font lock settings.  All ANSI keywords will be
 108 ;;    highlighted automatically, so only product specific keywords
 109 ;;    need to be defined here.

 187 ;;; To Do:
 188
 189 ;; Improve keyword highlighting for individual products.  I have tried
 190 ;; to update those database that I use.  Feel free to send me updates,
 191 ;; or direct me to the reference manuals for your favorite database.
 192
 193 ;; When there are no keywords defined, the ANSI keywords are
 194 ;; highlighted.  ANSI keywords are highlighted even if the keyword is
 195 ;; not used for your current product.  This should help identify
 196 ;; portability concerns.
 197
 198 ;; Add different highlighting levels.
 199
 200 ;; Add support for listing available tables or the columns in a table.

2881 `sql-mode' by calling \\[sql-mode].  The name of this buffer can be
2882 anything.  The name of the major mode is SQL.
2883

3775 When you put a buffer in SQL mode, the buffer stores the last SQLi
3776 buffer created as its destination in the variable `sql-buffer'.  This
3777 will be the buffer \\[sql-send-region] sends the region to.  If this
3778 SQLi buffer is killed, \\[sql-send-region] is no longer able to

3832 See `sql-help' for a list of available entry functions.
3833
3834 \\[comint-send-input] after the end of the process' output sends the
3835 text from the end of process to the end of the current line.
3836 \\[comint-send-input] before end of process output copies the current
3837 line minus the prompt to the end of the buffer and sends it.
3838 \\[comint-copy-old-input] just copies the current line.
3839 Use \\[sql-accumulate-and-indent] to enter multi-line statements.
3840
3841 If you want to make multiple SQL buffers, rename the `*SQL*' buffer
3842 using \\[rename-buffer] or \\[rename-uniquely] and start a new process.
3843 See `sql-help' for a list of available entry functions.  The last buffer
3844 created by such an entry function is the current SQLi buffer.  SQL
3845 buffers will send strings to the SQLi buffer current at the time of
3846 their creation.  See `sql-mode' for details.
3847
3848 Sample session using two connections:
3849
3850 1. Create first SQLi buffer by calling an entry function.
3851 2. Rename buffer \"*SQL*\" to \"*Connection 1*\".
3852 3. Create a SQL buffer \"test1.sql\".
3853 4. Create second SQLi buffer by calling an entry function.
3854 5. Rename buffer \"*SQL*\" to \"*Connection 2*\".
3855 6. Create a SQL buffer \"test2.sql\".
3856
3857 Now \\[sql-send-region] in buffer \"test1.sql\" will send the region to
3858 buffer \"*Connection 1*\", \\[sql-send-region] in buffer \"test2.sql\"
3859 will send the region to buffer \"*Connection 2*\".
3860
3861 If you accidentally suspend your process, use \\[comint-continue-subjob]
3862 to continue it.  On some operating systems, this will not work because
3863 the signals are not supported.
3864
3865 \\{sql-interactive-mode-map}
3866 Customization: Entry to this mode runs the hooks on `comint-mode-hook'
3867 and `sql-interactive-mode-hook' (in that order).  Before each input, the
3868 hooks on `comint-input-filter-functions' are run.  After each SQL
3869 interpreter output, the hooks on `comint-output-filter-functions' are
3870 run.
3871
3872 Variable `sql-input-ring-file-name' controls the initialization of the
3873 input ring history.
3874
3875 Variables `comint-output-filter-functions', a hook, and
3876 `comint-scroll-to-bottom-on-input' and
3877 `comint-scroll-to-bottom-on-output' control whether input and output
3878 cause the window to scroll to the end of the buffer.
3879
3880 If you want to make SQL buffers limited in length, add the function
3881 `comint-truncate-buffer' to `comint-output-filter-functions'.
3882
3883 Here is an example for your init file.  It keeps the SQLi buffer a
