* Make sure the column name resolver does not try to duplicate Expr.u.zTokendrh2009-05-28

* Additional refinements to Expr handling. Restore compression of triggerdrh2009-05-28
| | | | | | expressions. Change Expr.zToken to Expr.u.zToken and added Expr.u.iValue. Remove an unnecessary ExprDup from CHECK constraint processing. And so forth. (CVS 6682) FossilOrigin-Name: 4ac2bdfbb4230b6ceaae87e738fa61036bbe03cb
* Simplifications to the Expr object: Remove Expr.span completely and convertdrh2009-05-27

* Record within the Token structure itself whether or not the token hasdrh2009-05-01
| | | | | | been dequoted. This steals one bit from the length of a token and thus limits the size of tokens to 1GiB. (CVS 6589) FossilOrigin-Name: 12bcb03d9b9e1a31c1a3c67cbb4263cc0af2f3d0

* Scan an index instead of a table for "SELECT count(*) FROM <tbl>" queries. ↵danielk19772009-02-23
| | | | | Because an index is usually smaller than a table on disk, this saves some IO. (CVS 6315) FossilOrigin-Name: 294ba6f743c9132dce0e73da480bd3c2071e7239
