在INTEGER型阵营天然博览会的SQLite限于4个字节？

Question

当试图插入一个符号整数等于4个字节 - 1个比特（即，2 ^ 31即2147483648）我得到一个整数溢出条件（即，它被转换为-2147483648）。

SQLite的文档陈述INTEGER型多达8字节符号整数支持：https://www.sqlite.org/datatype3.html上述8个字节的值。另外 - 1个比特 - 1只引起一个异常。因此，这导致了它是一个博览会/反应母语错误的想法。这是世博会/反应本地/别的一个已知的bug？我找不到where ExponentSQLite is coming from。还要注意，2147483648远低于JavaScript的MAX_SAFE_INTEGER所以也许在机器人代码的参数被转换成4字节带符号整数。

import { SQLite } from 'expo'

async function main() {
  const db = SQLite.openDatabase('mydb')

  await exec_sql({ db, sql: `DROP TABLE IF EXISTS table_name;` })
  await exec_sql({ db, sql: `CREATE TABLE table_name (id INTEGER PRIMARY KEY, created_at INTEGER NOT NULL);` })
  await exec_sql({ db, sql: `INSERT INTO table_name (created_at) VALUES (?);`, parameters: [Math.pow(2, (8 * 4) - 1) - 1] })
  await exec_sql({ db, sql: `INSERT INTO table_name (created_at) VALUES (?);`, parameters: [Math.pow(2, (8 * 4) - 1)] })

  await exec_sql({ db, sql: `INSERT INTO table_name (created_at) VALUES (9223372036854775000);`, parameters: [] })
  // set to 9223372036854775000 as javascript Number.MAX_SAFE_INTEGER means `Math.pow(2, (8 * 8) - 1) - 1`
  // is rounded higher to 9223372036854776000
  await exec_sql({ db, sql: `INSERT INTO table_name (created_at) VALUES (?);`, parameters: [9223372036854775000] })

// This will error with
  // Error in callNativeModules()
  // Over flow during conversion: 9223372036854776000 (rounding up due to javascript's Number.MAX_SAFE_INTEGER)
  // await exec_sql({ db, sql: `INSERT INTO table_name (created_at) VALUES (?);`, parameters: [Math.pow(2, (8 * 8) - 1)] })
  await exec_sql({ db, sql: `SELECT * FROM table_name;` })
}

main()

function exec_sql ({ db, sql, parameters = [] }) {
  return new Promise((resolve, reject) => {
    db.transaction(tx => {
      console.debug(`Executing ${sql} with parameters: ${parameters}`)
      tx.executeSql(sql, parameters,
        (_, result) => {
          console.debug(`Have result: ${JSON.stringify(result)}`)
          if (result && result.rows && result.rows._array) {
            resolve({ items: result.rows._array })
          } else {
            resolve()
          }
        },
        (_, err) => {
          console.error(`Error during executing sql: `, err)
          reject(err)
        }
      )
    })
  })
}

这将导致（编辑为简洁起见）：

Executing CREATE TABLE IF NOT EXISTS table_name (id INTEGER PRIMARY KEY, created_at INTEGER NOT NULL); with parameters: 
Executing INSERT INTO table_name (created_at) VALUES (?); with parameters: 2147483647
Executing INSERT INTO table_name (created_at) VALUES (?); with parameters: 2147483648
Executing INSERT INTO table_name (created_at) VALUES (9223372036854775000); with parameters: 
Executing INSERT INTO table_name (created_at) VALUES (?); with parameters: 9223372036854775000
Executing SELECT * FROM table_name; with parameters: 
Have result: [{"id": 1, "created_at": 2147483647}, {"id": 2, "created_at": -2147483648}, {"id": 3, "created_at": -808},{"id": 4, "created_at": -1024}]
