The problem is with column datatype.

问题是列数据类型。

You tried to insert 26931139928208758813621215525179134210220 into number column which obviously generate overflow error.

您试图插入26931139928208758813621215525179134210220到number列，这显然会产生溢出错误。

You should change datatype of checksum column to string/binary.

您应该将checksum列的数据类型更改为string/binary。
