type Value

type Value int

Value represents go data types which carta supports for loading as well as what data types arrive from the sql driver

const (
	Invalid Value = iota
	Time
	Timestamp
	NullBool
	NullFloat64
	NullInt32
	NullInt64
	NullString
	NullTime
	Float64
	Float32
	Int
	Int8
	Int16
	Int32
	Uint
	Uint8
	Uint16
	Uint32
	Int64
	Uint64
	Bool
	String //  note, []uint8get converted to string, this is because mysql returns []uint8 for varchar while pg returns string
)

NOTE, carta does NOT support loading []uint8, any data that arrives from sql database as []uint8 is converted to bytes and expected field type is a string or *string
