| # ST_AsText |
| |
| Introduction: Return the `BOX(xmin ymin, xmax ymax)` text representation of a `Box2D` value. The format matches PostGIS's text representation of the `box2d` type and is intended for display and round-tripping with PostGIS-compatible tooling — not as a parseable round-trip into Sedona (use [ST_MakeBox2D](../Box2D-Constructors/ST_MakeBox2D.md) for that). |
| |
| This is the `Box2D` overload of `ST_AsText`; the [Geometry variant](../../Geometry-Output/ST_AsText.md) emits standard WKT. |
| |
| Format: `ST_AsText(box: Box2D)` |
| |
| Return type: `String` |
| |
| Since: `v1.9.1` |
| |
| SQL Example |
| |
| ```sql |
| SELECT ST_AsText(ST_MakeBox2D(ST_Point(0.0, 0.0), ST_Point(10.0, 20.0))) |
| ``` |
| |
| Output: |
| |
| ``` |
| BOX(0.0 0.0, 10.0 20.0) |
| ``` |
| |
| Returns `NULL` on `NULL` input. |
