Further improvements to the ".scanstats on" display in the shell. Be sure to show the results of all subqueries even if there are gaps in the SELECTID values. Add ".scanstats" to the ".help" output. Closed-Leaf check-in: ee922682 user: drh tags: scanstatus
12:17
On the ".scanstats on" output in the shell, initialize the estimated count for the first loop of each subquery to the actual loop count. check-in: d1c51c84 user: drh tags: scanstatus
12:08
Changes the formatting of ".scanstats on" in the shell so that the stats for subqueries are grouped together and occur after the main query. check-in: eacbbd88 user: drh tags: scanstatus
04:42
Add the SQLITE_SCANSTAT_SELECTID metric. Use it to improve the ".stmtscan on" output in the shell. check-in: 64ad5761 user: drh tags: scanstatus
03:55
Change the SQLITE_SCANSTAT_EST parameter so that it returns a double for the estimated number of output rows per loop, rather than a 64-bit integer. Revise the output format for the ".scanstats on" in the shell to make use of this new capability. check-in: f9684000 user: drh tags: scanstatus
