   ### What problem does this PR solve?
   
   The result of successful rewriting by the cbo optimizer depends on the 
statistics. The priority of the optimizer consumption statistics in descending 
order is the injected statistics, the statistics reported by be, and the 
statistics analyzed actively. When the pipeline runs the case, the statistics 
reported by be may not be timely. Therefore, the outcome that leads to the cbo 
optimizer's successful selection of overwrites is not very certain, so the 
statistics are currently injected manually in the test cases
