I would like to know the syntax for arcpy.sa or Raster Calculator to select the following:

1.  Band_1 from a raster where the Value is something specific.  Do I use ExtractByAttributes?  If so, what is the syntax to choose Band_1 from a multiband raster?
2.  Select from a combination of all three rasters like "Band_1","Value = 112"; "Band_2, "Value = 115"; "Band_3","Value = 5".  I have no idea of the syntax for this. 

http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//009z00000029000000.htm explains that you can use multiband rasters, but doesn't explain the syntax to do this.

Any help would be greatly appreciated.
