getWhereClause

public String getWhereClause()

Gets a SQL expression that defines which features are rendered.

The where clause string that is used as the getWhereClause() should follow standard SQL syntax similar to what is discussed in the document SQL reference for query expressions used in ArcGIS. A where clause that is not valid for the data may result in no features being drawn when this display filter is applied either by ManualDisplayFilterDefinition.getActiveFilter() or by ScaleRangeDisplayFilter.getMaxScale(). Check the layer's LayerViewState for a LayerViewStatus.WARNING; if there is one, then there might be LayerViewState.getError() describing that the display filter's where clause is not valid.

Returns:

a SQL expression that defines which features are rendered

Since:

100.13.0

setWhereClause

public void setWhereClause(String whereClause)

A where clause that is not valid for the data may result in no features being drawn when this display filter is applied either by ManualDisplayFilterDefinition.getActiveFilter() or by ScaleRangeDisplayFilter.getMaxScale(). Check the layer's LayerViewState for a LayerViewStatus.WARNING; if there is one, then there might be LayerViewState.getError() describing that the display filter's where clause is not valid.

Parameters:

whereClause - a SQL expression that defines which features are rendered

Throws:
