Re: Importing csv files containing multiple geometries in postgis

Hello Rose,

I checked that queries it Works. This syntax is ok. You can try it

INSERT INTO mygis_table( poly) VALUES( ST_GeomFromText('POINT(-5.8374796 43.3687922)', 4326));
INSERT INTO mygis_table( poly) VALUES( ST_GeomFromText('LINESTRING(-5.8427265 43.3678474,-5.8421236 43.3677908)', 4326));
INSERT INTO mygis_table( poly) VALUES( ST_GeomFromText('MULTIPOINT(-5.8445678 43.3589236,-5.8435222 43.358205,-5.8429834 43.3575551,-5.8429127 43.3572642)', 4326));

But this guery geometry is have problem. Could you kontrol this geomerty. İs it ok.

INSERT INTO mygis_table( poly) VALUES( ST_GeomFromText('POLYGON(-5.8335446 43.3655635,-5.8336337 43.3655207,-5.8349218 43.3673341,-5.8345197 43.3674013,-5.8336182 43.3660938,-5.8335037 43.365924,-5.8334505 43.3658461,-5.8334702 43.3657311,-5.8335446 43.3655635)', 4326));

in addition objectid is ıdid not use it . it is incrising autonumber.

Now ı am looking polygon geometry is is valid.

Best wishes.

Dear Selcuk,

Thanks a lot for your response. I have also attached my csv file :)

I tried to insert values into mygis_table, however, I am afraid I am getting the following errors. Can you please help me identify as to where am I going wrong:

testdbSpatial=# insert into mygis_table(objectid, poly)
values(1,GeomFromText('LINESTRING(198231 263418,198213 268322)',-1));
ERROR: function geomfromtext(unknown, integer) does not exist LINE 1: insert into mygis_table(objectid, poly) values(1,GeomFromTex...

HINT: No function matches the given name and argument types. You might need to add explicit type casts.
