Abstract
Embodiments of the present invention provide a method, system and computer program product for the table merging of correlated columns with row data reduction. In an embodiment of the invention, a method for table merging with row data reduction for merged columns can include selecting a first table of columns and a second table of columns for merger in a computer data processing system. A column of rows in the first table can be matched with a column of rows in the second table. Subsequently, it can be determined that the rows of the first table are the same in number as the rows of the second table and that the matched columns include identical data in the respective ones of the rows. Consequently, a merged table of an aggregation of the columns of the first table and the second table can be generated to exclude from the aggregation one of the matched columns that includes identical data in the respective ones of the rows as the other of the matched columns.
