- <p>Starting with version 2.7.0, the import engine has been re–written and
- these problems should not occur. If possible, upgrade your phpMyAdmin
- to the latest version to take advantage of the new import features.</p>
- <p>The first things to check (or ask your host provider to check) are the
- values of <tt class="docutils literal"><span class="pre">upload_max_filesize</span></tt>, <tt class="docutils literal"><span class="pre">memory_limit</span></tt> and
- <tt class="docutils literal"><span class="pre">post_max_size</span></tt> in the <tt class="file docutils literal"><span class="pre">php.ini</span></tt> configuration file. All of these
- three settings limit the maximum size of data that can be submitted
- and handled by PHP. One user also said that <tt class="docutils literal"><span class="pre">post_max_size</span></tt> and
- <tt class="docutils literal"><span class="pre">memory_limit</span></tt> need to be larger than <tt class="docutils literal"><span class="pre">upload_max_filesize</span></tt>.
- There exist several workarounds if your upload is too big or your
- hosting provider is unwilling to change the settings:</p>
- <ul>
- <li><p class="first">Look at the <span class="target" id="index-2"></span><a class="reference internal" href="config.html#cfg_UploadDir"><tt class="xref config config-option docutils literal"><span class="pre">$cfg['UploadDir']</span></tt></a> feature. This allows one to upload a file to the server
- via scp, ftp, or your favorite file transfer method. PhpMyAdmin is
- then able to import the files from the temporary directory. More
- information is available in the <a class="reference internal" href="config.html#config"><em>Configuration</em></a> of this document.</p>
- </li>
- <li><p class="first">Using a utility (such as <a class="reference external" href="http://www.ozerov.de/bigdump.php">BigDump</a>) to split the files before
- uploading. We cannot support this or any third party applications, but
- are aware of users having success with it.</p>
- </li>
- <li><p class="first">If you have shell (command line) access, use MySQL to import the files
- directly. You can do this by issuing the “source” command from within
- MySQL:</p>

- <p>Since phpMyAdmin 3.0.x, only MySQL 5.0.1 and newer are supported. For
- older MySQL versions, you need to use the latest 2.x branch.
- phpMyAdmin can connect to your MySQL server using PHP’s classic <a class="reference external" href="http://php.net/mysql">MySQL
- extension</a> as well as the <a class="reference external" href="http://php.net/mysqli">improved MySQL
- extension (MySQLi)</a> that is available in PHP
- 5.0. The latter one should be used unless you have a good reason not
- to do so. When compiling PHP, we strongly recommend that you manually
- link the MySQL extension of your choice to a MySQL client library of
- at least the same minor version since the one that is bundled with
- some PHP distributions is rather old and might cause problems see

- <p>You tried to access MySQL with an old MySQL client library. The
- version of your MySQL client library can be checked in your phpinfo()
- output. In general, it should have at least the same minor version as
- your server - as mentioned in <a class="reference internal" href="#faq1-17"><em>1.17 Which MySQL versions does phpMyAdmin support?</em></a>. This problem is
- generally caused by using MySQL version 4.1 or newer. MySQL changed
- the authentication hash and your PHP is trying to use the old method.
- The proper solution is to use the <a class="reference external" href="http://www.php.net/mysqli">mysqli extension</a> with the proper client library to match
- your MySQL installation. Your chosen extension is specified in

- <p>To connect to a MySQL server, PHP needs a set of MySQL functions

- phpMyAdmin tried to load the extension but failed. Usually, the

- or something similar.</p>

- <p>For RedHat users, Harald Legner suggests this on the mailing list:</p>
- <p>On my RedHat-Box the socket of MySQL is <em>/var/lib/mysql/mysql.sock</em>.
- In your <tt class="file docutils literal"><span class="pre">php.ini</span></tt> you will find a line</p>
- <div class="highlight-ini"><div class="highlight"><pre><span class="na">mysql.default_socket</span> <span class="o">=</span> <span class="s">/tmp/mysql.sock</span>

- </div>
- <p>change it to</p>
- <div class="highlight-ini"><div class="highlight"><pre><span class="na">mysql.default_socket</span> <span class="o">=</span> <span class="s">/var/lib/mysql/mysql.sock</span>
- </pre></div>
- </div>
- <p>Then restart apache and it will work.</p>
- <p>Here is a fix suggested by Brad Ummer:</p>
- <ul class="simple">
- <li>First, you need to determine what socket is being used by MySQL. To do
- this, telnet to your server and go to the MySQL bin directory. In this
- directory there should be a file named <em>mysqladmin</em>. Type
- <tt class="docutils literal"><span class="pre">./mysqladmin</span> <span class="pre">variables</span></tt>, and this should give you a bunch of info
- about your MySQL server, including the socket (<em>/tmp/mysql.sock</em>, for
- example).</li>
- <li>Then, you need to tell PHP to use this socket. To do this in
- phpMyAdmin, you need to complete the socket information in the
- <tt class="file docutils literal"><span class="pre">config.inc.php</span></tt>. For example:
- <span class="target" id="index-8"></span><a class="reference internal" href="config.html#cfg_Servers_socket"><tt class="xref config config-option docutils literal"><span class="pre">$cfg['Servers'][$i]['socket']</span></tt></a> Please also make sure that
- the permissions of this file allow to be readable by your webserver (i.e.
- ‘0755’).</li>
- </ul>
- <p>Have also a look at the <a class="reference external" href="http://dev.mysql.com/doc/en/can-not-connect-to-server.html">corresponding section of the MySQL
- documentation</a>.</p>

- <p>This depends on your system. If you’re running a server which cannot be
- accessed by other people, it’s sufficient to use the directory protection
- bundled with your webserver (with Apache you can use <a class="reference internal" href="glossary.html#term-htaccess"><em class="xref std std-term">.htaccess</em></a> files,
- for example). If other people have telnet access to your server, you should use
- phpMyAdmin’s <a class="reference internal" href="glossary.html#term-http"><em class="xref std std-term">HTTP</em></a> or cookie authentication features.</p>
- <p>Suggestions:</p>
- <ul class="simple">
- <li>Your <tt class="file docutils literal"><span class="pre">config.inc.php</span></tt> file should be <tt class="docutils literal"><span class="pre">chmod</span> <span class="pre">660</span></tt>.</li>
- <li>All your phpMyAdmin files should be chown -R phpmy.apache, where phpmy

- <p>Slow down :). Defining mimetypes is of no use, if you can’t put

What is this variable for?<a class="headerlink" href="#bookmarks-where-can-i-store-bookmarks-why-can-t-i-see-any-bookmarks-below-the-query-box-what-is-this-variable-for" title="Permalink to this headline">¶</a></h3>
- <p>Any query you have executed can be stored as a bookmark on the page
- where the results are displayed. You will find a button labeled
- ‘Bookmark this query’ just at the end of the page. As soon as you have
- stored a bookmark, it is related to the database you run the query on.
- You can now access a bookmark dropdown on each page, the query box
- appears on for that database.</p>
- <p>You can also have, inside the query, a placeholder for a variable.
- This is done by inserting into the query a SQL comment between <tt class="docutils literal"><span class="pre">/*</span></tt> and
- <tt class="docutils literal"><span class="pre">*/</span></tt>. Inside the comment, the special string <tt class="docutils literal"><span class="pre">[VARIABLE]</span></tt> is used.
- Be aware that the whole query minus the SQL comment must be
- valid by itself, otherwise you won’t be able to store it as a bookmark.</p>
- <p>When you execute the bookmark, everything typed into the <em>value</em>
- input box on the query box page will replace the string <tt class="docutils literal"><span class="pre">/*[VARIABLE]*/</span></tt> in
- your stored query.</p>
- <p>Also remember, that everything else inside the <tt class="docutils literal"><span class="pre">/*[VARIABLE]*/</span></tt> string for
- your query will remain the way it is, but will be stripped of the <tt class="docutils literal"><span class="pre">/**/</span></tt>
- chars. So you can use:</p>
- <div class="highlight-mysql"><div class="highlight"><pre><span class="cm">/*, [VARIABLE] AS myname */</span>
- </pre></div>
- </div>
- <p>which will be expanded to</p>
- <div class="highlight-mysql"><div class="highlight"><pre><span class="p">,</span> <span class="n">VARIABLE</span> <span class="k">as</span> <span class="n">myname</span>
- </pre></div>
- </div>
- <p>in your query, where VARIABLE is the string you entered in the input box. If an
- empty string is provided, no replacements are made.</p>
- <p>A more complex example. Say you have stored
- this query:</p>
- <div class="highlight-mysql"><div class="highlight"><pre><span class="k">SELECT</span> <span class="n">Name</span><span class="p">,</span> <span class="n">Address</span> <span class="k">FROM</span> <span class="n">addresses</span> <span class="k">WHERE</span> <span class="mi">1</span> <span class="cm">/* AND Name LIKE '%[VARIABLE]%' */</span>
- </pre></div>
- </div>
- <p>Say, you now enter “phpMyAdmin” as the variable for the stored query, the full
- query will be:</p>
- <div class="highlight-mysql"><div class="highlight"><pre><span class="k">SELECT</span> <span class="n">Name</span><span class="p">,</span> <span class="n">Address</span> <span class="k">FROM</span> <span class="n">addresses</span> <span class="k">WHERE</span> <span class="mi">1</span> <span class="k">AND</span> <span class="n">Name</span> <span class="k">LIKE</span> <span class="s1">'%phpMyAdmin%'</span>
- </pre></div>
- </div>
- <p>You can use multiple occurrences of <tt class="docutils literal"><span class="pre">/*[VARIABLE]*/</span></tt> in a single query
- (that is, multiple occurrences of the <em>same</em> variable).</p>
- <p><strong>NOTE THE ABSENCE OF SPACES</strong> inside the <tt class="docutils literal"><span class="pre">/**/</span></tt> 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.</p>
- <p>Your initial query which is going to be stored as a bookmark has to yield at
- least one result row so you can store the bookmark. You may have that to work
- around using well positioned <tt class="docutils literal"><span class="pre">/**/</span></tt> comments.</p>

- locate this feature by selecting a table and clicking the <em class="guilabel">Search</em>
- tab. One of the sub-tabs in the <em class="guilabel">Table Search</em> page is
- <em class="guilabel">Zoom Search</em>.</p>
- <p>Consider the table REL_persons in <a class="reference internal" href="#faq6-6"><em>6.6 How can I use the relation table in Query-by-example?</em></a> for
- an example. To use zoom search, two columns need to be selected, for

- represented as a point in a scatter plot based on its id and
- town_code. You can include two additional search criteria apart from
- the two fields to display.</p>
- <p>You can choose which field should be
- displayed as label for each point. If a display column has been set
- for the table (see <a class="reference internal" href="#faqdisplay"><em>6.7 How can I use the “display column” feature?</em></a>), it is taken as the label unless
