Abstract: A merge join process combines rows from an inner and an outer table when the inner table is indexed on a data column that is common to both tables. The merge join process creates a set of rows from the outer table that satisfy a selection criteria and sorts the rows in the set on the common data column if necessary. The merge join process searches for a matching inner row for each outer row in sequence using the inner table indices until it finds a matching inner row on a data page. The data page is then repeatedly searched for matches on the successive outer rows in the set until the end of the data page is reached. The end of the data page is reached when the value of the common data column in an outer row is greater than a last key that represents the highest value of the common data column in a inner row stored on the data page.
