    sql multiple joins convert rows to column on same table without using pivot
    In SQL, multiple joins can be utilized to merge data from the same table, converting rows to columns without explicitly using the PIVOT function. By joining a table with itself through aliases, different sets of data can be extracted and aligned horizontally. Each join establishes a relationship between the original and aliased instances based on specified conditions. This technique allows for the creation of a consolidated result set where each row corresponds to a unique identifier, and the columns represent different attributes or categories. It's a powerful method to horizontally organize information, transforming a vertically structured dataset into a more comprehensible, columnar format without relying on the PIVOT keyword.
