This topic describes the greater than operator (>). This operator determines whether the universally unique identifier (UUID) of the first specified raster object is greater than the UUID of the second.
Syntax
bool Operator >(raster rast1, raster rast2);
Parameters
Parameter | Description |
---|---|
rast1 | The raster object 1. |
rast2 | The raster object 2. |
Note This operator only compares the UUIDs of two specified raster objects. This operator
does not compare their spatial extents or pixel types. This operator is used only
for operations such as union and B-tree.
Examples
SELECT a.rast > b.rast
FROM tbl_a a, tbl_b b
WHERE a.id = b.id
