SDO_UTIL.THEME3D_HAS_TEXTURE(
     theme_name  IN VARCHAR2 
     ) RETURN NUMBER;

Description

Checks if a 3D theme has textures (for DEM, TIN, map tile server, and SDO_GEOMETRY themes).

Parameters

theme_name

Name of the 3D theme. Must be a value from the USER_SDO_3DTHEMES or ALL_SDO_3DTHEMES view (described in xxx_SDO_3DTHEMES Views.

Usage Notes

This function returns 0 (zero) if the theme does not have textures; otherwise, it returns 1.

Examples

This example does the following for each theme in the USER_SDO_3DTHEMES table: checks if it has multiple LODs and has texture, and returns the block table name. (It assumes that the themes were previously inserted into the USER_SDO_3DTHEMES table.)
