UPDATE statement in Impala?

Are you using KUDU as the underlining table? If not, then UPDATE is not supported. Please refer to below link:

"This statement only works for Impala tables that use the Kudu storage engine."

What's the error you are getting?

Have you tried to add ` around the day, since it is reserved as a UDF function? Like below:

update anp_catdidai1_working.dim_bsp_date set `day`=day(date_num);
