| 15:24 | Remove support for STAT3. The sqlite_stat3 tables are ignored, if they exist. STAT4 continues to work as it always has, and as it is a superset of STAT3 is the recommended replacement. file: [36ce5494] check-in: [1e17ea2f] user: drh branch: omit-stat3, size: 3685 | |

| 19:42 | More test case updates. Tests are all running now. file: [e32a9705] check-in: [dab5e529] user: drh branch: rework-EQP, size: 3693 | |

| 19:26 | Change the query planner to do a better job of estimating the number rows selected by a BETWEEN operator using STAT4 when both upper and lower bounds are contained within the same sample. file: [c05a461d] check-in: [2d36be5d] user: drh branch: trunk, size: 3737 | |

| 19:54 | Change the way ANALYZE works to use a single cursor when scanning indices. file: [093d15c1] check-in: [bdce612b] user: dan branch: sqlite_stat4, size: 3737 | |
|
2013-08-12
| ||
| 20:14 | If ENABLE_STAT3 is defined but ENABLE_STAT4 is not, have ANALYZE create and populate the sqlite_stat3 table instead of sqlite_stat4. file: [f3afd910] check-in: [cca8bf43] user: dan branch: sqlite_stat4, size: 3738 | |
|
2013-08-08
| ||
| 11:48 | Fix a bug in using stat4 data to estimate the number of rows selected by a range constraint. file: [8d1f76ff] check-in: [f783938e] user: dan branch: sqlite_stat4, size: 3730 | |
|
2013-08-03
| ||
| 20:24 | Begin adding experimental sqlite_stat4 table. This commit is buggy. file: [09242543] check-in: [2beea303] user: dan branch: sqlite_stat4, size: 3162 | |
|
2013-06-10
| ||
| 23:30 | Fix test cases for the new EXPLAIN QUERY PLAN format. Add the wherecosttest tool. Other fixes to logarithm cost. file: [ea4972c7] check-in: [aa580e36] user: drh branch: nextgen-query-plan-logcost, size: 3162 | |
|
2011-08-16
| ||
| 01:15 | Add the analyze8.test test module for sqlite_stat3. file: [4ca170de] check-in: [2c83ac89] user: drh branch: stat3-enhancement, size: 3273 Added | |

| 00:21 | The ANALYZE command adds the sqlite_stat2.cnt column if it does not already exist. file: [fbb37856] check-in: [794fde6f] user: drh branch: query-planner-tweaks, size: 5416 | |

| 19:48 | The sqlite_stat2.cnt field is parsed if it is present. But it is not yet used. A large comment added to analyze.c to explain the format of the ANALYZE system tables. file: [8a9c83bf] check-in: [6d1e2372] user: drh branch: query-planner-tweaks, size: 4568 | |
| 01:22 | Fix a compiler warning when STAT2 is off. More test cases. Fix legacy tests to deal with the new STAT2 logic. file: [ff7a3b46] check-in: [7e914aa9] user: drh branch: query-planner-tweaks, size: 4555 | |
