https://dev.mysql.com/doc/refman/8.0/en/spatial-geojson-functions.html
As specified in the GeoJSON specification, parsing is case-sensitive for the type member of the GeoJSON input (Point, LineString, and so forth). This section describes functions for converting between GeoJSON documents and spatial values. Feature ...

mysql> SET @g = "MULTILINESTRING((10 10, 11 11), (9 9, 10 10))"; mysql> SELECT ST_AsText(ST_GeomCollFromText(@g)); +--------------------------------------------+ | ST_AsText(ST_GeomCollFromText(@g)) | +--------------------------------------------+ | ... These functions take as arguments a Well-Known Text (WKT) representation and, optionally, a spatial reference system identifier ...
https://dev.mysql.com/doc/refman/8.0/en/spatial-aggregate-functions.html
If all arguments are LineString values, the result is a MultiLineString value. MySQL supports aggregate functions that perform a calculation on a set of values. For general information about these functions, see Section 14.19.1, “Aggregate ...
https://dev.mysql.com/doc/refman/8.0/en/keywords.html
Certain keywords, such as SELECT, DELETE, or BIGINT, are reserved and require special treatment for use as identifiers such as table and column names. This may also be true for the names of built-in functions. Some keywords which are otherwise ...
https://dev.mysql.com/doc/refman/8.0/en/information-schema-st-geometry-columns-table.html
Permitted values are: geometry, point, linestring, polygon, multipoint, multilinestring, multipolygon, geometrycollection. The ST_GEOMETRY_COLUMNS table provides information about table columns that store spatial data. This table is based on the ...
https://dev.mysql.com/doc/refman/8.0/en/gis-wkb-functions.html
ST_LineFromWKB(wkb [, srid [, options]]), ST_LineStringFromWKB(wkb [, srid [, options]]) Constructs a LineString value using its WKB representation and SRID. ST_MLineFromWKB(wkb [, srid [, options]]), ST_MultiLineStringFromWKB(wkb [, srid [, ...
https://dev.mysql.com/doc/refman/8.0/en/geometry-well-formedness-validity.html
For geometry values, MySQL distinguishes between the concepts of syntactically well-formed and geometrically valid. Spatial import functions that parse WKT or WKB values raise an error for attempts to create a geometry that is not syntactically ...
https://dev.mysql.com/doc/refman/8.0/en/gis-class-polygon.html
Polygon Assertions The boundary of a Polygon consists of a set of LinearRing objects (that is, LineString objects that are both simple and closed) that make up its exterior and interior boundaries. A Polygon is a planar Surface representing a ...
https://dev.mysql.com/doc/refman/8.0/en/gis-class-multipolygon.html
A MultiPolygon boundary is a set of closed curves (LineString values) corresponding to the boundaries of its Polygon elements. A MultiPolygon is a MultiSurface object composed of Polygon elements. MultiPolygon Examples On a region map, a ...
https://dev.mysql.com/doc/refman/8.0/en/gis-class-multilinestring.html
A MultiLineString is a MultiCurve geometry collection composed of LineString elements. MultiLineString Examples On a region map, a MultiLineString could represent a river system or a highway system.
