Bookmarks
|
||
|
|
=========
|
||
|
|
|
||
|
|
.. note::
|
||
|
|
|
||
|
|
You need to have configured the :ref:`linked-tables` for using bookmarks
|
||
|
|
feature.
|
||
|
|
|
||
|
|
Storing bookmarks
|
||
|
|
-----------------
|
||
|
|
|
||
|
|
Any query that is executed can be marked as a bookmark on the page
|
||
|
|
where the results are displayed. You will find a button labeled
|
||
|
|
:guilabel:`Bookmark this query` just at the end of the page. As soon as you have
|
||
|
|
stored a bookmark, that query is linked to the database.
|
||
|
|
You can now access a bookmark dropdown on each page where the query box appears on for that database.
|
||
|
|
|
||
|
|
Variables inside bookmarks
|
||
|
|
--------------------------
|
||
|
|
|
||
|
|
Inside a query, you can also add placeholders for variables.
|
||
|
|
This is done by inserting into the query SQL comments between ``/*`` and
|
||
|
|
``*/``. The special string ``[VARIABLE{variable-number}]`` is used inside the comments.
|
||
|
|
Be aware that the whole query minus the SQL comments must be
|
||
|
|
valid by itself, otherwise you won't be able to store it as a bookmark.
|
||
|
|
Also, note that the text 'VARIABLE' is case-sensitive.
|
||
|
|
|
||
|
|
When you execute the bookmark, everything typed into the *Variables*
|
||
|
|
input boxes on the query box page will replace the strings ``/*[VARIABLE{variable-number}]*/`` in
|
||
|
|
your stored query.
|
||
|
|
|
||
|
|
Also remember, that everything else inside the ``/*[VARIABLE{variable-number}]*/`` string for
|
||
|
|
your query will remain the way it is, but will be stripped of the ``/**/``
|
||
|
|
chars. So you can use:
|
||
|
|
|
||
|
|
.. code-block:: mysql
|
||
|
|
|
||
|
|
/*, [VARIABLE1] AS myname */
|
||
|
|
|
||
|
|
which will be expanded to
|
||
|
|
|
||
|
|
.. code-block:: mysql
|
||
|
|
|
||
|
|
, VARIABLE1 as myname
|
||
|
|
|
||
|
|
in your query, where VARIABLE1 is the string you entered in the Variable 1 input box.
|
||
|
|
|
||
|
|
A more complex example, say you have stored this query:
|
||
|
|
|
||
|
|
.. code-block:: mysql
|
||
|
|
|
||
|
|
SELECT Name, Address FROM addresses WHERE 1 /* AND Name LIKE '%[VARIABLE1]%' */
|
||
|
|
|
||
|
|
If you wish to enter "phpMyAdmin" as the variable for the stored query, the full
|
||
|
|
query will be:
|
||
|
|
|
||
|
|
.. code-block:: mysql
|
||
|
|
|
||
|
|
SELECT Name, Address FROM addresses WHERE 1 AND Name LIKE '%phpMyAdmin%'
|
||
|
|
|
||
|
|
**NOTE THE ABSENCE OF SPACES** inside the ``/**/`` construct. Any spaces
|
||
|
|
inserted there will be later also inserted as spaces in your query and may lead
|
||
|
|
to unexpected results especially when using the variable expansion inside of a
|
||
|
|
"LIKE ''" expression.
|
||
|
|
|
||
|
|
Browsing a table using a bookmark
|
||
|
|
---------------------------------
|
||
|
|
|
||
|
|
When a bookmark has the same name as the table, it will be used as the query when browsing
|
||
|
|
this table.
