The keyword that is used to combine the results of two or more tables based on a related column is JOIN. JOIN allows you to retrieve data from multiple tables by establishing a relationship between them through columns that have matching values. There are different types of JOINs, such as INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN, each serving different purposes in how data is fetched based on the relationships defined. When using JOIN, you specify which columns to use to combine the tables, allowing for more complex queries that draw on data distributed across different tables in a relational database. Other terms like MERGE, UNION, and LINK do not adequately describe the specific action of combining rows from multiple tables based on matching values. MERGE is typically used in different contexts, such as merging data sets or within procedural statements. UNION is utilized to combine the results of two or more SELECT queries, but it does not involve combining rows based on relationships between columns; rather, it appends the results as long as the same number of columns and compatible data types are present. LINK is not a standard SQL keyword associated with combining tables in the context described.
