- Abstract
The end of query is the composition of SQL statements, completed by using the graphical interface. Operator precedence grammar was combined with segmentation to identify query statement in graphic interface, this paper customized the semantic action and added correctness judgment "constraints( )", realized the composition of SQL and added fuzzy operator, multinational language library, process control, fault location and other language technology to make it more powerful, which was the expansion for SQL.
