Syntax\n------\n\nST_SRID(g)\nSRID(g)\n\nDescription\n-----------\n\nReturns an integer indicating the Spatial Reference System ID for the geometry value g.\n\nIn MariaDB, the SRID value is just an integer associated with the geometry value. All calculations are done assuming Euclidean (planar) geometry.\n\nST_SRID() and SRID() are synonyms.\n\nExamples\n--------\n\nSELECT SRID(GeomFromText('LineString(1 1,2 2)',101));\n+-----------------------------------------------+\n| SRID(GeomFromText('LineString(1 1,2 2)',101)) |\n+-----------------------------------------------+\n|                                           101 |\n+-----------------------------------------------+\n\nURL: https://mariadb.com/docs/server/reference/sql-statements/geometry-constructors/geometry-properties/st_srid
