Otherwise all regular user tableswill be treated as layers.<p>Regular (non-spatial) tables can be accessed, and will return features withattributes, but not geometry. If the table has a "st_*" field, it willbe 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 ofInformix 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></body></html>⌨️ 快捷键说明
