When I run the Spatial Analust tool Extraction\Extract by Attributes and use as input a raster that is stored in a .gdb I get an error and no output. If I look at the results window for the operation, the first line states "Output raster: <empty>". If I use a raster stored in the same directory as the .gdb for the input - it works fine. IT is only if the input raster is stored in a .gdb that I get the error and no output.
