…38731)
#38731
The stddev function has a separate implementation for the DecimalV2 type, but there are issues with the implementation. Given that there is almost no existing data for DecimalV2, it will be removed here. For be, upgrading to this situation will result in an error directly.

SELECT STDDEV(data) FROM DECIMALV2_10_0_DATA;
ERROR 1105 (HY000): errCode = 2, detailMessage = (127.0.0.1)[INTERNAL_ERROR]Agg Function stddev(decimal(10,0)) is not implemented

After removing DecimalV2, parameters of type DecimalV2 will be converted to double for calculations.
