From this page, it seems SQLite can save up to the max number of uint64:
The sqlite3_int64 and sqlite_int64 types can store integer values between -9223372036854775808 and +9223372036854775807 inclusive. The sqlite3_uint64 and sqlite_uint64 types can store integer values between 0 and +18446744073709551615 inclusive.
But I tried this with a simple table which has
id INTEGER PRIMARY KEY and
id UNSIGNED INTEGER PRIMARY KEY and with Golang's two SQLite drivers:
Both throw the error below when I tried to insert an id with the value 9223372036854775808, it works when the number is 9223372036854775807, but not bigger.
sql: converting argument $1 type: uint64 values with high bit set are not supported
The max number it can successfully write to the db is the max number of "signed int64", 9223372036854775807.
I am not sure if this is Golang driver's problem or SQLite itself's INTEGER doesn't really support a big uint64. Since I currently need to support the uint64 data, I guess I'll need to make the
id field as a
TEXT PRIMARY KEY.
