SE_layer_delete deletes the spatial components from a spatially enabled table.
For feature classes that have been implemented using the binary schema (Oracle and SQL Server only), deleting a feature class drops the DBMS spatial tables (the F and S tables), removes the definition of the feature class from the ArcSDE system tables COLUMN_REGISTRY, GEOMETRY_COLUMNS, and LAYERS, and drops the trigger on the spatial column. Under the SQL spatial types and functions implementations, the spatial column is unaltered, but the feature class definition is removed from the ArcSDE system tables COLUMN_REGISTRY, GEOMETRY_COLUMNS, and LAYERS. On SQL Server, the geometry side tables (used for CAD storage) are also dropped.
For all types of feature classes, the business table still exists in the database and is registered (a record still exists for it in the TABLE_REGISTRY table). To completely remove the business table after removing its spatial component, use SE_table_delete.
If the caller of this function is neither the owner of the table nor the ArcSDE administrator, an error is returned.
If an ArcSDE layer has become corrupted for some reason (e.g., the user has dropped one of the internal ArcSDE tables or deleted the layer definition record accidentally), SE_layer_delete still attempts to delete the layer.

Tip
∙ Use SE_layer_truncate to delete features but retain the layer definition.
