Review Comment:
In addition to supporting the use of widened DecimalType to read int and
long; I also refer to the previously customized decimal logic type #41409 to
read long, which is also supported when reading int.
If you think that these two parts are not suitable to be placed in one PR, I
can seperate them apart.
