React native expo SQLite 中的 INTEGER 类型限制为 4 个字节?

INTEGER type in React native expo SQLite limited to 4 bytes?

当尝试插入一个等于 4 字节 - 1 位的有符号整数(即 2^31,即 2147483648)时,我得到一个整数溢出条件(即它被转换为 -2147483648)。

sqlite 文档声明 INTEGER 类型最多支持 8 字节有符号整数:https://www.sqlite.org/datatype3.html 此外,超过 8 个字节 - 1 位 - 1 的值会导致异常。所以这导致了它是一个 expo / react-native bug 的想法。这是 Expo / react-native / 其他的已知错误吗?我找不到 where ExponentSQLite is coming from。另请注意,2147483648 远低于 javascript MAX_SAFE_INTEGER,因此可能在 android 代码中,参数被转换为 4 字节有符号整数。

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(为简洁起见进行了编辑):

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:
