|19:52||Remove an unused token type. (check-in: 13a42223 user: drh tags: covering-index-on-expr)|
|19:41||Proof of concept for the ability to use the expression columns in an index on expressions in place of equivalent expressions in the result set or in the WHERE clause. This check-in compiles but is mostly untested. (check-in: a52ef2ad user: drh tags: covering-index-on-expr)|
