>ST_SummaryStats() Hi Pierre,
I try it , but i'm not sure to understand the results. The docs say it return the stats for a given raster band of a raster coverage. I assume this was mean It return me a single row of values for the raster table. Instead It return me many records of type SummaryStats. It seem to return a result for every table row. I'm not soo skilled on the raster to well understand what is a row table in a raster table. I guess, perhaps, it is the tile ? If yes, this mean it is returning the stats for every tile. And so my quest now is how to retrieve the total stat for all the raster table. Also I cannot try the group by because the ST_SummaryStats is not an aggregate function. This is the query I try: select ST_SummaryStats(rast_column) from my_schema.my_table; Thx, -- ----------------- Andrea Peri . . . . . . . . . qwerty àèìòù -----------------
