**Is your feature request related to a problem? Please describe.** The current version cannot support modifying the aggregation type of columns from REPLACE to REPLACE_IF_NOT_NULL. ``` alter table mytbl MODIFY column pv BIGINT REPLACE_IF_NOT_NULL NULL; ERROR 1064 (HY000): errCode = 2, detailMessage = Can not change aggregation type ``` This operation is very common because there are too many restrictions with replace, the original data will be overwritten with a value of NULL if there is any mistake. So for us, the use cost is relatively high. **Describe the solution you'd like** support modifying a column from replace to replace_if_not_null, or from replace_if_not_null to replace **Describe alternatives you've considered** A clear and concise description of any alternative solutions or features you've considered. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
