Is there a SQL way to run spatialitegui RTTOPO SanitizeGeometry?

[Andrea Borruso]

Hi,

is there a SQL way to run RTTOPO SanitizeGeometry command of the spatialite-gui app (using the default sanitize option)?

Thank you

ciao Andrea,

the GUI wizard is fully based on the standard RTTOPO MakeValid()
function, it simply add some bonus value such as producing an
HTML detailed report.

you can get the same practical effect by using a pure SQL
statement as:

UPDATE geom = MakeValid(geom) FROM my_table;

or even better:

UPDATE geom = MakeValid(geom)
FROM my_table
WHERE ST_IsValid(geom) <> 1;

happy new year,

Grazie mille Sandro and happy new year to you and mailing list users.

I have used

UPDATE table SET  geom  = MakeValid( geom  )

WHERE ST_IsValid( geom  ) <> 1;
