属性值
类型：Microsoft.SqlServer.Management.Smo.SpatialGeoLevelSize
The first level of decomposition for a geometry data type.
注释
The index-creation process decomposes the space into a four-level grid hierarchy. These levels are referred to as level 1 (the top level), level 2, level 3, and level 4.
Each successive level further decomposes the level above it, so each upper-level cell contains a complete grid at the next level. On a given level, all the grids have the same number of cells along both axes (for example, 4x4 or 8x8), and the cells are all one size.
This property cannot be modified by using the Alter method. To change the property, the index must be rebuilt or re-created.
