Description
this query takes about 10 minutes
SELECT ac.id, ac.iso_n3, ac.iso_a2, ac.iso_a3, ac.dial_code, ac.zip_format, ac.name_long, ac.name, ac.name_un_long, ac.name_un, ac.default_lang_id, ac.default_currency_id, ac.states, ac.region_type_primary, ac.region_type_secondary, ac.continent, ac.neighbours, ac.languages, ac.tld, ac.currency_code, ac.dummy FROM `global`.`address_country` ac WHERE ac.dummy IS NULL AND ac.id IN(SELECT DISTINCT id FROM `global`.`address_country_shape` acs WHERE ST_INTERSECTS(shape,@var56d318005292f)) ORDER BY ac.name
|
the problem is with st intersects part
address_country_shape has about 300 rows
in @var there some polyline, should not be more that 1000 points
it usually works but with some polyline it took a long time
it says Copying to tmp table and the cpu is on 100%
