Method Details

sqlGeometryRelations

public String sqlGeometryRelations(SpatialQueryFilter filter)

Description copied from interface: IEgdbDialect

This method is used to build the specific sql statement for a SQLServer database when a spatial filter is going to be used. Spatial filters use methods to determine relationships between geometries. For example if two geometries intersect or overlap. In the case of SQLServer, different methods exist.

Specified by:

sqlGeometryRelations in interface IEgdbDialect

Returns:

String that represents the query to execute.

geometryTypeQueryCondition

public String geometryTypeQueryCondition(String[] geometryType)

typedef enum { SE_OGC_GEOMETRY = 0, SE_OGC_POINT = 1, SE_OGC_CURVE = 2, SE_OGC_LINESTRING = 3, SE_OGC_SURFACE = 4, SE_OGC_POLYGON = 5, SE_OGC_COLLECTION = 6, SE_OGC_MULTIPOINT = 7, SE_OGC_MULTICURVE = 8, SE_OGC_MULTILINESTRING = 9, SE_OGC_MULTISURFACE = 10, SE_OGC_MULTIPOLYGON = 11 } SE_OGC_GEOMETRY_TYPES;

Specified by:

geometryTypeQueryCondition in interface IEgdbDialect

Returns:

Query string to check the geometry type

sqlQueryAvailableGeometryType

public String sqlQueryAvailableGeometryType()

Description copied from interface: IEgdbDialect

Build the query statement to get the geometry type of the layer

Specified by:

sqlQueryAvailableGeometryType in interface IEgdbDialect

Returns:

Query string to be executed to extract the geometry type
