Abstract: The present application discloses a virtual column construction method based on data lake and a data query method. The present disclosure includes: first, automatically performing expression statistical analysis on a large quantity of statements to be analyzed in a data lake, so as to obtain an expression to be used; next, automatically constructing a virtual column construction request corresponding to the expression to be used, according to virtual column construction description information corresponding to the expression to be used, so that the virtual column construction request is used to request construction of a virtual column that can represent the expression to be used; then, according to the virtual column construction request, constructing a virtual column corresponding to the expression to be used, to enable the virtual column to represent the expression to be used.
