无法使用 react-native-sqlite-storage 在 SQLite 中执行任何查询...我正在为 android 电视应用程序尝试
Unable to execute any query in SQLite with react-native-sqlite-storage ...i am trying it for android tv app
Blockquote
我还使用 table 创建了数据库并将其存储到 android/app/src/main/assets/sqlite.db
并将 createFromLocation 设置为 1 或 2
useEffect(() => {
try {
db = SQLite.openDatabase({
name: "sqlite.db",
createFromLocation:"~sqlite.db"
},
sucessToOpen,
errorToOpen
)
}
catch (err) {
console.log(err)
}
}, [])
....
const sucessToOpen = async (data) => {
console.log("DB connected",data)
db.transaction(tx => {
tx.executeSql(
'SELECT * FROM hydro',[],
(tx, results) => {
let datalength = results.row.length
alert(datalength)
console.log("results",datalength)
},
)
});
}
这对我有用
db.transaction(tx => {
tx.executeSql('SELECT * FROM TABLE_NAME', [], (tx, results) => {
var temp = [];
for (let i = 0; i < results.rows.length; ++i) {
temp.push(results.rows.item(i));
}
console.log('TABLE_NAME', temp)
});
});
