How can I INSERT INTO using results of a query?

PaulFrank — Tue, 26 Nov 2019 19:33:25 GMT

Hello,

Is it possible to use an st_geometry function that is part of a SELECT statement to INSERT records into an Oracle SDE geodatabase (12g)? I have constructed the following statement from which I receive Error ORA-00917; missing comma.

INSERT INTO gis_table
(objectid, gis_table_id, shape)
VALUES (1, 2, (sde.st_geometry ('polygon((SELECT sde.st_astext(sde.st_buffer(l.shape, 500)) as shapebuffer FROM location.address_point l where l.place_id = 802689))', 2277))

The part of the query

SELECT sde.st_astext(sde.st_buffer(l.shape, 500)) as shapebuffer FROM location.address_point l where l.place_id = 802689

returns and Oracle type CLOB, which turns out to actually be POLYGON (( 3112886.18568189 10066866.95637797, 3112885.11514598 10066899.65808421, etc etc)), So I see I may be duplicating the keyword POLYGON, but I have changed that and I get other errors. Or I freely admit I may be using the wrong functions or process to do this.

Thanks in advance of the great answers I am sure to get...

I tried to simplify this down to just the ST functions, but this might help get us in the right direction. Here is how I did an INSERT INTO SELECT with an ST_BUFFER:

insert into gis_table (shape) select sde.st_buffer(l.shape, 0.05) from location l;‍‍

If I add in attribute records it changes slightly:

insert into gis_table (objectid, gis_table_id,shape) select 1,2,sde.st_buffer(l.shape, 0.005) from location l;‍

In the original script, there are some duplication of the ST calls with the ST_GEOMETRY + ST_ASTEXT function. There are 2 reasons I would avoid the additional call for WKT.

ST_BUFFER returns an ST_GEOMETRY object and can be reused in your insert statement without rework
The WKT is returned as a Character Large Object (CLOB), which can be unwieldy and quite large to store in memory - this becomes more important as you scale your SQL requests.

Have you tried a select into statement?

SELECT *

INTO newtable

FROM oldtable

WHERE condition;

Thanks everyone. I modified the query to this and good news - I dont receive a syntax error, just ORA-01031: insufficient privileges! I suspect I dont have those for the geometry_st functions? I am asking my IT about that. BTW, I also tried it without the where clause as suggested, and I get the same error.

INSERT INTO planningcadastre.demolition_notifications_gis
(OBJECTID, NOTIFICATION_ID, SHAPE)
select 1,2,sde.st_buffer(l.shape, 500) from location.address_point l where l.place_id = 802689;

Glad to hear we made some progress! On the insufficient permissions it might be the tables from the LOCATION or PLANNINGCADASTRE schema. Can you verify that you can do a SELECT one each table without the ST call? Can you verify you can do an INSERT on DEMOLITION_NOTIFICATIONS_GIS without the ST call?

Yes I am still seeing the error when I try to insert a buffer manually, so that would seem to be the issue, although I tried to add a fairly large polygon that I shortened for viewing purposes:

INSERT INTO planningcadastre.demolition_notifications_gis
(OBJECTID, NOTIFICATION_ID, SHAPE)
VALUES (4, 5, sde.st_geometry('polygon ((3122386.18571073 10066866.95637797, 3122364.77499239 10067520.98755021, 3122300.63437265 10068172.21820313, 3122194.03845723 10068817.85962838, 3122045.44393815 10069455.14673963, 3121855.48696898 10070081.35119589, 3121624.98119640 10070693.79058780, ...3122300.63437265 10065561.69455279, 3122364.77499239 10066212.92520571, 3122386.18571073 10066866.95637797)',2277))
