# STOverlaps (geometry Data Type)

Returns 1 if a geometry instance overlaps another geometry instance. Returns 0 if it does not.

## Syntax

```
.STOverlaps ( other_geometry )
```

## Arguments

- other_geometry

Is another geometry instance to compare against the instance on which STOverlaps() is invoked.

## Return Types

SQL Server return type: bit

CLR return type: SqlBoolean

## Remarks

Two geometry instances overlap if the region representing their intersection has the same dimension as the instances do, and the region does not equal either instance.

STOverlaps() always returns 0 if the points where the geometry instances intersect are not the same dimension.

This method always returns null if the spatial reference IDs (SRIDs) of the geometry instances do not match.

## Examples

The following example uses STOverlaps() to test two geometry instances for overlap.

```
DECLARE @g geometry;
DECLARE @h geometry;
SET @g = geometry::STGeomFromText('POLYGON((0 0, 2 0, 2 2, 0 2, 0 0))', 0);
SET @h = geometry::STGeomFromText('POLYGON((1 1, 3 1, 3 3, 1 3, 1 1))', 0);
SELECT @g.STOverlaps(@h);
```
