[postgis-users] How can i interchange(swap) the values of a band in postgis raster

[Zelio Fernandes]

thanks for your reply......
but if ST_Band(rast,2,1) means that i am assigning the value of 2nd raster
band to 1st......will it create a new raster with this.......i tried this
...but i m not sure whether it creates new raster or it replaces values in
same raster.
