OracleSpatial getFeatureInfo problem against unique column containing text

[Bart van den Eijnden (OSGIS)]

No this is not possible.

You need to use an integer for the unique column. It's a requirement.

Best regards,

> Hi,

> I have a view in Oracle Spatial 10gR2 with a unique Id, which is text.
> MapServer draws the map OK using oraclespatial CONNECTIONTYPE.
> However, MapServer is unable to serve a getFeatureInfo request against 
> that view. If I change the DATA statement to substr(ID, 3,7), removing 
> letters from the ID - getFeatureInfo runs fine for the time being, but 
> without the letters my ID will soon lose its uniqueness.
