MySQL: Invalid GIS data provided to function st_ge

问题:

Here's my code:

SET @poly =
    'Polygon((-98.07697478272888 30.123832577126326,
              -98.07697478272888 30.535734310413392,
              -97.48302581787107 30.535734310413392,
              -97.48302581787107 30.123832577126326))';

SELECT name
FROM county_shapes
WHERE MBRContains(ST_GeomFromText(@poly), SHAPE);

Whenever I run that I get a "MySQL: Invalid GIS data provided to function st_geometryfromtext" error.

This returns the same error:

SELECT name
FROM county_shapes
WHERE MBRContains(ST_GeomFromText('Polygon((-98.07697478272888 30.123832577126326,
              -98.07697478272888 30.535734310413392,
              -97.48302581787107 30.535734310413392,
              -97.48302581787107 30.123832577126326))'), SHAPE);

Any ideas?

You need to specify the first and last point as same.

Try this.

SET @poly =
    'Polygon((-98.07697478272888 30.123832577126326,
              -98.07697478272888 30.535734310413392,
              -97.48302581787107 30.535734310413392,
              -97.48302581787107 30.123832577126326,
              -98.07697478272888 30.123832577126326,))';

SELECT name
FROM county_shapes
WHERE MBRContains(ST_GeomFromText(@poly), SHAPE);

AND

SELECT name
FROM county_shapes
WHERE MBRContains(ST_GeomFromText('Polygon((
              -98.07697478272888 30.123832577126326,
              -98.07697478272888 30.535734310413392,
              -97.48302581787107 30.535734310413392,
              -97.48302581787107 30.123832577126326,
              -98.07697478272888 30.123832577126326))'), SHAPE);
