ABSTRACT:
Systems and methods are provided for automatically creating an SQL join expression. A computer-implemented graphical user interface may receive a first user input that identifies a first table to be included in the SQL join expression and a second user input that identifies a second table to be included in the SQL join expression. Software instructions stored in a computer-readable medium may automatically define the SQL join expression by matching one or more keys or indices in the first table with one or more keys or indices in the second table.
