Work fast with our official CLI. It's a burden to find all views which might reference the table which has been changes, This can be used to determine the order in which views should be refreshed or replaced/installed from metadata, Can also be used with the load dependency analysis, Parsing the view allows us to build a set of disjunctions used in WHERE clauses, Some of the views contain some very, very weird things.

If the parse-tree can be suitably analysed, more efficient equivalent queries can be automatically generated. The simple-sql-parser is a lot less simple than it used to be. Type inference is done with CHR, and types are in one of three states:
If you just need to parse much simpler SQL than this, or want to start with a simpler parser and modify it slightly, you could also look at the basic query parser in the intro_to_parsing project, the code is here: SimpleSQLQueryParser. sql_tokens(Tokens, "CREATE VIEW foo AS SELECT bar FROM qux", ), sql_parse(view_definition(Definition, Types), TrailingComments, , Tokens).
