Find Long/Lat inside of polygon with MySQL 5.6


I have a locations table that has many rows of locations and data. There are 2 columns inside of that - Longitude and Latitude. I want to find records from that table that are found in a defined map polygon area.

I have a second table that I just created based on some tutorials called polyThing which has my defined boundary...

CREATE TABLE polyThing ( `ID` int auto_increment primary key, `boundary` polygon not null, `testarea` varchar(200) NOT NULL ); INSERT INTO polyThing (boundary, testarea) VALUES( PolygonFromText( 'POLYGON(( -114.018522 46.855932 , -113.997591 46.856030 , -113.997447 46.848626 , -114.018161 46.848824 , -114.018522 46.855932 ))' ), 'Test Area 1' );

I want to find records from locations that are inside this defined polygon, and I've been trying queries similar to this. I get 0 records no matter what I try.

SELECT * FROM locations WHERE ST_CONTAINS( (SELECT boundary FROM polyThing WHERE polyThing.testarea = 'Test Area 1') , Point(Longitude, Latitude))

Here is locations table and data:

CREATE TABLE `locations` ( `LocationID` int(11) NOT NULL, `Location` varchar(200) NOT NULL, `Longitude` varchar(200) NOT NULL, `Latitude` varchar(200) NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=latin1 ROW_FORMAT=COMPACT; INSERT INTO `locations` (`LocationID`, `Location`, `Longitude`, `Latitude`) VALUES (1, 'In the polygon', '-114.007191', '46.853019'), (2, 'In the polygon', '-114.003798', '46.851045'), (3, 'Not in', '-114.016934', '46.866098');

Love to get a nudge in the right direction.


I guess (Longitude, l.Latitude) are in locations?

<strong><a href="http://http://rextester.com/JSLYC95685" rel="nofollow">Sql DEMO:</a></strong>

SELECT l.*, ST_CONTAINS(p.boundary, POINT(l.Longitude, l.Latitude)) FROM locations l CROSS JOIN polyThing p; SELECT l.* FROM locations l JOIN polyThing p ON ST_CONTAINS(p.boundary, POINT(l.Longitude, l.Latitude)) AND p.testarea = 'Test Area 1';
