Hi @jiyfhust. Thanks for your PR.

I'm waiting for a pingcap member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Review for Partition: Fix Select Statement Error on Table which Partitioned by Column with Floor Func

Summary

The pull request fixes the problem of some SELECT statements not working properly on tables which are partitioned by column with the FLOOR() function. Before the fix, the partition function was not properly handled, leading to an error in these specific cases. The PR includes a modified test case to verify the bug fix.

Potential Problems

The PR does not present significant issues.

Fixing Suggestions

The PR looks good overall. One suggestion would be to expand the tests to cover more use cases and improve the robustness of the test suite. However, this might be tackled in a separate PR.

Another suggestion is to ensure that the naming used is consistent with the established naming conventions used in the project.

Overall Impression

The pull request is well written and allows for better use of the partition feature. The code changes have been implemented correctly, and the test results are consistent. Thus, I suggest this pull request should be merged.
