Info

Registration • Registration informs the geodatabase of tables or views containing spatial attributes created outside ArcGIS • Registration writes information about these tables and the spatial attribute into the geodatabase system tables so ArcGIS can access them properly – Description p of the table’s attributes – Type of features in the spatial attribute – Spatial reference information
Using ArcObjects • Nothing gp prevents the application pp developer p from consuming relational operators via ArcObjects //Oracle, // , st_ggeometry y pQueryDef = pFeatureWorkspace.CreateQueryDef(); pQueryDef.Tables = “tb.parcels”, “tb.neighborhoods”; pQueryDef.SubFields = “parcels.objectid"; pQueryDef.WhereClause Q D f Wh Cl = “sde.st_intersects(parcels.shape, neighborhoods.shape) = 1”; pCursor = pQueryDef.Evaluate(); IRow pRow = pCursor.NextRow(); iint t pCnt C t = 00; if (pRow != null) { pCnt = pCnt + 1; MMarshal.ReleaseComObject(pRow); h l R l C Obj t( R ) }
