Abstract
A code conversion apparatus first combines key columns, and detects a first function code for executing a grouping operation for each combined key column, next detects a key column name from the first function code, next generates a group key using the key column name for each two-dimensional array data of the first function code, next detects overlap key column names in the group keys, and generates an overlap group composed of the overlap key column names, next adds a second function code for executing a grouping operation using the overlap group name of the overlap group and the key column names constituting the overlap group, and a third function code for adding the overlap group name to the two-dimensional array data as a key column, and next replaces the key column name used in the overlap group included in the first function code with the overlap group name.
