<div class="refsect1">
<a name="GdaConnection.description"></a><h2>Description</h2>
<p>Each connection to a database is represented by a <a class="link" href="GdaConnection.html" title="GdaConnection"><span class="type">GdaConnection</span></a> object. A connection is created (and opened)
using <a class="link" href="GdaConnection.html#gda-connection-open-from-dsn" title="gda_connection_open_from_dsn ()"><code class="function">gda_connection_open_from_dsn()</code></a> if a data source has been defined, or <a class="link" href="GdaConnection.html#gda-connection-open-from-string" title="gda_connection_open_from_string ()"><code class="function">gda_connection_open_from_string()</code></a>
otherwise. It is not recommended to create a <a class="link" href="GdaConnection.html" title="GdaConnection"><span class="type">GdaConnection</span></a> object using <a href="/usr/share/gtk-doc/html/gobject/gobject-The-Base-Object-Type.html#g-object-new"><code class="function">g_object_new()</code></a> as the results are
unpredictable (some parts won't correctly be initialized).</p>
<p>Use the connection object to execute statements, use transactions, get meta data information, ...</p>
<p>If supported by the database provider being used, statements can be executed asynchronously instead of
blocking the execution thread untill the execution of a statement is finished. Each database provider
is free to implement this feature as it wishes (using the API or using threads). The steps involved to
execute a statement are then:</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>Request the statement execution using
<a class="link" href="GdaConnection.html#gda-connection-async-statement-execute" title="gda_connection_async_statement_execute ()"><code class="function">gda_connection_async_statement_execute()</code> which returns an
  execution ID to be used to identify a specific request</a></p></li>
<li class="listitem"><p>Do some useful things (that is why async. statements' excution are for)</p></li>
<li class="listitem"><p>Use one or more times 
<a class="link" href="GdaConnection.html#gda-connection-async-fetch-result" title="gda_connection_async_fetch_result ()"><code class="function">gda_connection_async_fetch_result()</code></a> to see
if the execution is finished, using the request ID</p></li>
<li class="listitem"><p>Use <a class="link" href="GdaConnection.html#gda-connection-async-cancel" title="gda_connection_async_cancel ()"><code class="function">gda_connection_async_cancel()</code></a> to cancel
the execution of a statement</p></li>
</ul></div>
<p>The <a class="link" href="GdaConnection.html" title="GdaConnection"><span class="type">GdaConnection</span></a> object implements its own locking mechanism so it is thread-safe. However ad some database
providers rely on an API which does not support threads or supports it only partially, the connections
opened using those providers will only be accessible from the thread which created them (any other thread will
be blocked trying to access the connection, use the</p>
<GTKDOCLINK HREF="gda-lockable-try-lock"><code class="function">gda_lockable_try_lock()</code></GTKDOCLINK> method to check it the connection
<p>is usable from a thread).</p>
<p>If a connection really needs to be accessed by several threads at once, then it is possible to pass the
<a class="link" href="GdaConnection.html#GDA-CONNECTION-OPTIONS-THREAD-SAFE:CAPS"><span class="type">GDA_CONNECTION_OPTIONS_THREAD_SAFE</span></a> flag when opening it. This flag requests that the real connection
be created and really accessed in a <span class="emphasis"><em>private</em></span> sub thread.</p>

<p>Opens a connection given a provider ID and a connection string. This
allows applications to open connections without having to create
a data source (DSN) in the configuration. The format of <em class="parameter"><code>cnc_string</code></em>
 is
similar to PostgreSQL and MySQL connection strings. It is a semicolumn-separated
series of &lt;key&gt;=&lt;value&gt; pairs, where each key and value are encoded as per RFC 1738, 
see <a class="link" href="libgda-5.0-Utility-functions.html#gda-rfc1738-encode" title="gda_rfc1738_encode ()"><code class="function">gda_rfc1738_encode()</code></a> for more information.</p>
<p>The possible keys depend on the provider, the "gda-sql-5.0 -L" command
can be used to list the actual keys for each installed database provider.</p>
<p>For example the connection string to open an SQLite connection to a database
file named "my_data.db" in the current directory would be <code class="constant">"DB_DIR=.;DB_NAME=my_data"</code>.</p>
<p>The <em class="parameter"><code>cnc_string</code></em>
 string must have the following format: 
"&lt;provider&gt;://@]&lt;connection_params&gt;"
(if &lt;username&gt; and/or &lt;password&gt; are provided, and <em class="parameter"><code>auth_string</code></em>
 is <a href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a>, then these username
and passwords will be used, and if &lt;provider&gt; is provided and <em class="parameter"><code>provider_name</code></em>
 is <a href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a> then this
provider will be used). Note that if provided, &lt;username&gt;, &lt;password&gt; and  &lt;provider&gt;
must be encoded as per RFC 1738, see <a class="link" href="libgda-5.0-Utility-functions.html#gda-rfc1738-encode" title="gda_rfc1738_encode ()"><code class="function">gda_rfc1738_encode()</code></a> for more information.</p>
<p>The <em class="parameter"><code>auth_string</code></em>
 must contain the authentication information for the server
to accept the connection. It is a string containing semi-colon seperated named values, usually 
like "USERNAME=...;PASSWORD=..." where the ... are replaced by actual values. Note that each
name and value must be encoded as per RFC 1738, see <a class="link" href="libgda-5.0-Utility-functions.html#gda-rfc1738-encode" title="gda_rfc1738_encode ()"><code class="function">gda_rfc1738_encode()</code></a> for more information.</p>
<p>The actual named parameters required depend on the provider being used, and that list is available
as the <em class="parameter"><code>auth_params</code></em> member of the <a class="link" href="libgda-5.0-Configuration.html#GdaProviderInfo" title="struct GdaProviderInfo"><span class="type">GdaProviderInfo</span></a> structure for each installed

string, use the "gda-sql-5.0 -L" command to list the possible named parameters.</p>
<p>Additionally, it is possible to have the connection string
respect the "&lt;provider_name&gt;://&lt;real cnc string&gt;" format, in which case the provider name
and the real connection string will be extracted from that string (note that if <em class="parameter"><code>provider_name</code></em>

is not <a href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a> then it will still be used as the provider ID).\</p>
<p>This method may fail with a GDA_CONNECTION_ERROR domain error (see the <a class="link" href="GdaConnection.html#GdaConnectionError" title="enum GdaConnectionError"><span class="type">GdaConnectionError</span></a> error codes)

 does not contain the GDA_STATEMENT_MODEL_RANDOM_ACCESS or
GDA_STATEMENT_MODEL_CURSOR_FORWARD flags, then the default will be to return a random access data model</p>
<p>Note5: If <em class="parameter"><code>stmt</code></em>
 is a SELECT statement which returns blob values (of type <a class="link" href="libgda-5.0-Gda-Value.html#GDA-TYPE-BLOB:CAPS" title="GDA_TYPE_BLOB"><code class="literal">GDA_TYPE_BLOB</code></a>), then an implicit
transaction will have been started by the database provider, and it's up to the caller to close the transaction
(which will then be locked) once all the blob ressources have been
liberated (when the returned data model is destroyed). See the section about</p>
Binary large objects (BLOBs) for more information.

<p>This method is similar to <a class="link" href="GdaConnection.html#gda-connection-statement-execute" title="gda_connection_statement_execute ()"><code class="function">gda_connection_statement_execute()</code></a> but is asynchronous as it method returns
immediately with a task ID. It's up to the caller to use <a class="link" href="GdaConnection.html#gda-connection-async-fetch-result" title="gda_connection_async_fetch_result ()"><code class="function">gda_connection_async_fetch_result()</code></a> regularly to check
if the statement's execution is finished.</p>
<p>It is possible to call the method several times to request several statements to be executed asynchronously, the
statements will be executed in the order in which they were requested.</p>
<p>The parameters, if present, are copied and can be discarded or modified before the statement is actually executed.
The <em class="parameter"><code>stmt</code></em>
 object is not copied but simply referenced (for performance reasons), and if it is modified before
it is actually executed, then its execution will not occur. It is however safe to call <a href="/usr/share/gtk-doc/html/gobject/gobject-The-Base-Object-Type.html#g-object-unref"><code class="function">g_object_unref()</code></a> on it if
it's not needed anymore.</p>
<p>The execution failure of any statement has no impact on the execution of other statements except for example if
the connection has a transaction started and the failure invalidates the transaction (as decided by the database
server).</p>
<p>Note that for asynchronous calls to succeed, it is gererally necessary to specify the
<a class="link" href="GdaConnection.html#GDA-CONNECTION-OPTIONS-THREAD-ISOLATED:CAPS"><code class="literal">GDA_CONNECTION_OPTIONS_THREAD_ISOLATED</code></a> flag when opening the connection to be sure it is opened in a separate thread
in which asynchronous calls are made (failing to use this flag make the asynchronous call dependant on the database
provider implementation and at the moment none support this feature).</p>

<p>Updates <em class="parameter"><code>cnc</code></em>
's associated <a class="link" href="GdaMetaStore.html" title="GdaMetaStore"><span class="type">GdaMetaStore</span></a>. If <em class="parameter"><code>context</code></em>
 is not <a href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a>, then only the parts described by
<em class="parameter"><code>context</code></em>
 will be updated, and if it is <a href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a>, then the complete meta store will be updated. Detailed
explanations follow:</p>
<p>In order to keep the meta store's contents in a consistent state, the update process involves updating
the contents of all the tables related to one where the contents change. For example the "_columns"
table (which lists all the columns of a table) depends on the "_tables" table (which lists all the tables
in a schema), so if a row is added, removed or modified in the "_tables", then the "_columns" table's contents
needs to be updated as well regarding that row.</p>
<p>If <em class="parameter"><code>context</code></em>
 is <a href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a>, then the update process will simply overwrite any data that was present in all the
meta store's tables with new (up to date) data even if nothing has changed, without having to build the
tables' dependency tree. This is the recommended way of proceeding when dealing with a meta store which
might be outdated.</p>
<p>On the other hand, if <em class="parameter"><code>context</code></em>
 is not <a href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a>, then a tree of the dependencies has to be built (depending on
<em class="parameter"><code>context</code></em>
) and only some parts of the meta store are updated following that dependencies tree. Specifying a
context may be useful for example in the following situations:</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>One knows that a database object has changed (for example a table created), and
                  may use the <em class="parameter"><code>context</code></em> to request that only the information about that table be updated
            </p></li>
<li class="listitem"><p>One is only interested in the list of views, and may request that only the information
                  about views may be updated</p></li>
</ul></div>
<p>When <em class="parameter"><code>context</code></em>
 is not <a href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a>, and contains specified SQL identifiers (for example the "table_name" of the "_tables"
table), then each SQL identifier has to match the convention the <a class="link" href="GdaMetaStore.html" title="GdaMetaStore"><span class="type">GdaMetaStore</span></a> has adopted regarding
case sensitivity, using <a class="link" href="GdaConnection.html#gda-connection-quote-sql-identifier" title="gda_connection_quote_sql_identifier ()"><code class="function">gda_connection_quote_sql_identifier()</code></a> or <a class="link" href="GdaMetaStore.html#gda-meta-store-sql-identifier-quote" title="gda_meta_store_sql_identifier_quote ()"><code class="function">gda_meta_store_sql_identifier_quote()</code></a>.</p>

<a class="link" href="GdaSqlParser.html#gda-sql-identifier-quote" title="gda_sql_identifier_quote ()"><code class="function">gda_sql_identifier_quote()</code></a> function which will be most useful.</p>
<p>Note however that usually <span class="emphasis"><em>more</em></span> information will be updated than strictly requested by

      <span class="emphasis"><em>MyTable</em></span>, then usually the database will create a table named
      <span class="emphasis"><em>mytable</em></span>, whereas with this flag, the table will be created
      as <span class="emphasis"><em>MyTable</em></span> (note that in the end the database may still decide
      to name the table <span class="emphasis"><em>mytable</em></span> or differently if it can't do
      otherwise).</p></li>
<li class="listitem"><p>Libgda will not apply this rule when parsing SQL code, the SQL code being parsed
      has to be conform to the database it will be used with</p></li>
</ul></div>
<p>Additional information about the GDA_CONNECTION_OPTIONS_THREAD_SAFE and GDA_CONNECTION_OPTIONS_THREAD_ISOLATED flags:
The GDA_CONNECTION_OPTIONS_THREAD_SAFE flag specifies that it has to be able to use the returned connection object from
several threads at once (locking is ensured by the <a class="link" href="GdaConnection.html" title="GdaConnection"><span class="type">GdaConnection</span></a> itself). Depending on the database provider's
implementation and on the native libraries it uses, the "normal" connection object might not respect this requirement,
and in this case a specific thread is started and used as the unique thread which will manipulate the actual connection,
while a "wrapper connection" is actually returned and used by the caller (that wrapper connection passes method calls
from the calling thread to the actual connection's specific thread, and gets the results back).</p>
<p>The GDA_CONNECTION_OPTIONS_THREAD_ISOLATED forces using a specific thread and a "wrapper connection" even if the
"normal" connection would itself be thread safe; this is useful for example to be sure the asynchronous API can
always be used (see <a class="link" href="GdaConnection.html#gda-connection-async-statement-execute" title="gda_connection_async_statement_execute ()"><code class="function">gda_connection_async_statement_execute()</code></a>).</p>
<p>Having a specific thread and a "wrapper connection" definitely has an impact on the performances (because it involves
messages passing between threads for every method call), so using the
GDA_CONNECTION_OPTIONS_THREAD_SAFE or GDA_CONNECTION_OPTIONS_THREAD_ISOLATED flags should be carefully considered.</p>
<p>Note about the <em class="parameter"><code>GDA_CONNECTION_OPTIONS_AUTO_META_DATA</code></em>
 flag:</p>
