Should we consider ShouldClipToZero
?

I think we need to consider this.
we extract a uint from the json, it must not < 0.
// GetInt64 gets the int64 value.
func (bj BinaryJSON) GetInt64() int64 {
return int64(endian.Uint64(bj.Value))
}
// GetUint64 gets the uint64 value.
func (bj BinaryJSON) GetUint64() uint64 {
return endian.Uint64(bj.Value)
}

why not directly create a json column?

If directly creat json, then I can not get a uint field(#11386 (comment)).

how about casting '9223372036854775808' to uint then cast to json?

What problem does this PR solve?
In the origin version
ConvertIntToUint(sc, j.GetInt64(), IntergerUnsignedUpperBound(mysql.TypeLonglong), mysql.TypeLonglong)
, whenj.GetInt64()
return neg number such as1<<63
, thenConvertIntToUint
may treat it as overflow, this is a bug.What is changed and how it works?
Replace
j.GetInt64
byj.GetUint64
