Error when inserting a point into MariaDB.

[yemzz]

Hello! I have this problem. I populated the database using PointFromText and select queries work correctly. But I can't insert a new Point into the table.

_, err := tx.ExecContext(ctx, `
      INSERT INTO localities (
	      title,
	      coords
      )
      VALUES (?, ST_GeomFromWKB(?))
`,
      locality.Title,
      wkb.Value(locality.Coords),
)

Error 4079: Illegal parameter data type char for operation 'st_geometryfromwkb'

There have been recent changes to this. See the ewkb readme for information on how to read/write from maria db.

The following two options worked for me

coord := orb.Point{1, 2}

// as WKB in hex format
data := wkb.MustMarshalToHex(coord)
db.Exec("INSERT INTO geodata(geom) VALUES (ST_GeomFromWKB(UNHEX(?), 4326))", data)

// relying on the raw encoding
db.Exec("INSERT INTO geodata(geom) VALUES (?)", ewkb.ValuePrefixSRID(coord, 4326))
