sql - Can STWithin or STContains be used to update columns based on point within polygon relationship? -

given next tables:

create table #usgs_24k_topomap_boundaries( [objectid] [int] not null, [area] [numeric](38, 8) null, [perimeter] [numeric](38, 8) null, [qd24k_grsm] [numeric](38, 8) null, [qd24k_gr_1] [numeric](38, 8) null, [quadid] [numeric](38, 8) null, [centlat] [numeric](38, 8) null, [centlong] [numeric](38, 8) null, [name] [nvarchar](35) null, [state] [nvarchar](2) null, [latlong] [nvarchar](9) null, [ohio_index] [nvarchar](8) null, [grid60] [nvarchar](5) null, [reviewed] [int] null, [corrected] [int] null, [verified] [int] null, [globalid] [uniqueidentifier] not null, [shape] [geometry] null)

and

create table #tbl_locations( [objectid] [int] not null, [fcategory] [varchar](16) null, [mapmethod] [varchar](4) null, [herror] [varchar](50) null, [mapsource] [varchar](255) null, [sourcedate] [datetime2](7) null, [editdate] [datetime2](7) null, [notes] [varchar](255) null, [species_community] [varchar](50) null, [location_id] [uniqueidentifier] not null, [site_id] [uniqueidentifier] null, [gis_location_id] [varchar](50) null, [meta_mid] [varchar](50) null, [x_coord] [numeric](38, 8) null, [y_coord] [numeric](38, 8) null, [coord_units] [varchar](50) null, [coord_system] [varchar](50) null, [utm_zone] [varchar](50) null, [accuracy_notes] [varchar](255) null, [unit_code] [varchar](12) null, [loc_name] [varchar](100) null, [loc_type] [varchar](25) null, [updated_date] [varchar](50) null, [loc_notes] [varchar](255) null, [datum] [varchar](5) null, [watershed] [varchar](50) null, [streamname] [varchar](50) null, [nhdreachcode] [varchar](14) null, [topo_name] [varchar](50) null, [trail] [varchar](100) null, [road] [varchar](50) null, [elevation] [numeric](38, 8) null, [lat] [numeric](38, 8) null, [lon] [numeric](38, 8) null, [population_id] [uniqueidentifier] null, [year_] [varchar](4) null, [wgs_dat] [varchar](5) null, [wgs_cs] [varchar](5) null, [county] [varchar](20) null, [state] [varchar](15) null, [isextant] [varchar](3) null, [issenstive] [varchar](3) null, [speciesname] [varchar](125) null, [speciesid] [varchar](50) null, [species_id] [int] null, [shape] [geometry] null)

i'd populate #tbl_locations.topo_name #usgs_24k_topomap_boundaries.name. in other words, trying determine name of topo map point falls within, , programatically write points table. seems simple in theory, tbl_locations contains thousands of points occur in 1 of 36 topo map polygon boundaries.

i've gotten far

select name, loc_name, location_id #usgs_24k_topomap_boundaries a, #tbl_locations b a.shape.stcontains(b.shape)=1

which returns neat table can cross-walk tbl_locations through join, i'm stuck on getting accomplished through single query-update statement, , have many similar point-polygon relationships i'd automate way (e.g watershed, county, state, etc... point occurs in). thanks!

update tbl_locations set topo_name = dbo.qd24k_grsm.name --(select a.name, b.loc_name, b.location_id dbo.tbl_locations inner bring together dbo.qd24k_grsm on tbl_locations.location_id = tbl_locations.location_id (qd24k_grsm.shape.stcontains(tbl_locations.shape) = 1) ;

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
