Syntaxe

'Déclaration

'Utilisation

Valeur de retour

Type : Microsoft.SqlServer.Types. . :: . .SqlGeometry
A SqlGeometry object that represents the union of all points whose distance from the calling SqlGeometry is less than or equal to the specified value.

Notes

STBuffer calculates a buffer in the same manner as BufferWithTolerance, that specifies tolerance = distance * .001 and relative = true.

A negative buffer removes all points within the given distance of the boundary of the SqlGeometry.
