Abstract
The subject mater herein relates to database management and, more particularly, to non-equijoin metadata. Various embodiments described herein provide systems, methods, software, and data structures to facilitate non-equijoins of data. Some such embodiments include a data store to hold metadata describing relationships between database tables. The relationships between database tables may include one or more non-equijoins of tables in the form of one or more table-column pairs of a first table being non-equal to one or more table-column pairs of a second table. In some embodiments, the metadata may be used by a query generator to build query statements including one or more non-equijoin.
