Abstract

See full text

A system and method for configuring, sequencing and viewing joins in a query is provided. The system includes an advanced joins viewer that may be invoked from an SQL Query Tool. A graphical user interface associated with the advanced joins viewer displays a sequenced vertical tile list of each table and each intermediate result set in a particular query. Through this interface, a user may re-sequence the ordering of the tables and thus reconfigure the intermediate result sets that are generated by the query. The advanced joins viewer enables the independent configuration of the join type and the join relationships for each of the intermediate result sets. An automatic sequencing algorithm is also provided for configuring the ordering of the tables such that the query produces valid SQL.
