[postgis-users] problem using st_colormap in a command string

[Tumasgiu Rossini]

Sure :

   strColorMap &= "nv 0 0 0 0\n"
   strCores &= val_nivel1 & " 255 0 145 255\n"
   strCores &= val_nivel2 & " 181 19 111 255\n"
   strCores &= val_nivel3 & " 19 0 104 255\n"
   strCommand = "SELECT ST_ColorMap( rast, E'" + strColorMap + "') as rast
FROM tb_rasterdensity"

See www.postgresql.org/docs/9.6/static/sql-syntax-lexical.html  4.1.2.2.
