I have a DEM like below image. The black area shows 0-values.

I want to remove cells of 0-values in the raster.  

Example

In raster calculator, I wrote con("demclip_re@1">0,"demclip_re@1") but it gives "Incorrect expression".

What is wrong with my expression?

Con is an ArcGIS raster tool which is not available in QGIS.

If you want to replace all 0 value cells with nodata, you could use something like:

("demclip_re@1") / ("demclip_re@1">0)
