## Description

Converts a standard figure WKB (Well-known binary) to the corresponding memory geometry

## Alias

- ST_GEOMFROMWKB

## Syntax

```sql
ST_GEOMETRYFROMWKB( <wkb>)
```
## Parameters

| Parameters | Instructions |
|------------|---------|
| `<wkb>`  | The memory form of the graph |

## Return Value

The corresponding geometric storage form of WKB

## Examples

```sql
select ST_AsText(ST_GeometryFromWKB(ST_AsBinary(ST_Point(24.7, 56.7))));
```

```text
+------------------------------------------------------------------+
| st_astext(st_geometryfromwkb(st_asbinary(st_point(24.7, 56.7)))) |
+------------------------------------------------------------------+
| POINT (24.7 56.7)                                                |
+------------------------------------------------------------------+
```

```sql
select ST_AsText(ST_GeomFromWKB(ST_AsBinary(ST_Point(24.7, 56.7))));
```

```text
+--------------------------------------------------------------+
| st_astext(st_geomfromwkb(st_asbinary(st_point(24.7, 56.7)))) |
+--------------------------------------------------------------+
