[postgis-users] raster band failed

[Ahmet Temiz]

​hello

I am trying to create a raster band that cont​ains slope values.

I used this code, but failed

​--UPDATE o_20_trdem22 SET rast = ST_AddBand( rast, ST_Slope(
--            ST_AddBand(
--               rast,
--                        '8BUI'::text, 1, 0
--                      )
--   , 1, '8BUI') )
​
​what should I have done ?

regards​
