我在以下代码中使用“react-native-sqlite-storage”
import SQLite from 'react-native-sqlite-storage';
SQLite.DEBUG(true);
SQLite.enablePromise(true);
//"test.db", "1.0", "Test Database", 200000, openCB, errorCB)
const db = SQLite.openDatabase({name: 'mydb.db'});
//'CREATE TABLE IF NOT EXISTS transactions (id INTEGER PRIMARY KEY NOT NULL, date TEXT NOT NULL, start TEXT NOT NULL, end TEXT NOT NULL);'
export const initdb = () => {
const promise = new Promise((resolve, reject) => {
db.transaction(tx => {
tx.executeSql(
'CREATE TABLE IF NOT EXISTS transactions (id INTEGER PRIMARY KEY NOT NULL, date TEXT NOT NULL, start TEXT NOT NULL, end TEXT NOT NULL);',
[],
() => {
resolve();
},
(_, err) => {
reject(err);
},
);
});
});
return promise;
};
我正在使用以下代码
initdb()
.then(() => {
console.log('Sucessfully Initialised Databse ');
})
.catch(error => {
console.log('Failed Database');
console.log(error);
});
我怎么在日志中得到这个错误
LOG Promise based runtime ready
LOG OPEN database: mydb.db
LOG SQLite.open({"name":"mydb.db","dblocation":"nosync"})
LOG Failed Database
LOG [TypeError: undefined is not a function (near '...db.transaction...')]
LOG Running "timekeep" with {"rootTag":1,"initialProps":{}}
我在ios模拟器上试试
