<title>Informix DataBlade Driver</title>
</head>

<p>This driver implements support for access to spatial tables in
IBM Informix extended with the DataBlade spatial module.

<p>When opening a database, it's name should be specified in the form

<pre>"IDB:dbname={dbname} server={host} user={login} pass={pass} table={layertable}".</pre>

<p>The IDB: prefix is used to mark the name as a IDB connection string.

<p>If the <i>geometry_columns</i> table exists, then all listed tables and
named views will be treated as OGR layers.  Otherwise all regular user tables
will be treated as layers.

<p>Regular (non-spatial) tables can be accessed, and will return features with
attributes, but not geometry.  If the table has a "st_*" field, it will
be treated as a spatial table. The type of the field is inspected to
determine how to read it.

<p>Driver supports automatic FID detection.

<h3>Environment variables</h3>
<ul>
<li><b>INFORMIXDIR</b>: It should be set to Informix client SDK install dir
<li><b>INFORMIXSERVER</b>: Default Informix server name
<li><b>DB_LOCALE</b>: Locale of Informix database
<li><b>CLIENT_LOCALE</b>: Client locale
<li><b>IDB_OGR_FID</b>: Set name of primary key instead of 'ogc_fid'.
</ul>

<p>For more information about Informix variables read documentation of
Informix Client SDK

<h3> Example </h3>
<p>This example shows using ogrinfo to list Informix DataBlade layers on a different host.

<pre>
ogrinfo -ro IDB:"server=demo_on user=informix dbname=frames"
</pre>
