使用React Native在Sqlite中插入多条记录

使用React Native在Sqlite中插入多条记录,sqlite,react-native,expo,Sqlite,React Native,Expo,我尝试使用SQLite在React Native中插入多行 代码如下: rows = responseJson.rows; for (i = 0; i < rows.length; i++) { row=rows[i]; query = `insert into ComuniUserAccountSync values ( ${row.IDComuniUserAccountSync}, ${row

我尝试使用SQLite在React Native中插入多行

代码如下:

rows = responseJson.rows;

     for (i = 0; i < rows.length; i++) {

        row=rows[i];
        query = `insert into ComuniUserAccountSync values (
            ${row.IDComuniUserAccountSync},
            ${row.IdAzienda},
            ${row.IdComune},
            ${row.IdUserAccount},
            '${row.DescrizioneComune}',
            '${row.DateLastUpdateMaster}'
        )`;


        db.transaction(
            tx => {
                tx.executeSql(query, [], (a,b) =>
                    console.log("!OK!!", JSON.stringify(b)), (a, b) =>
                        console.log("!ERROR!!", a, b)
                )

            }
       );

     }
!!好啊{“rowsAffected”:0,行:{“{U数组”:[{“IDComuniUserAccountSync”:72},{“IDComuniUserAccountSync”:72},{“IDComuniUserAccountSync”:72},{“IDComuniUserAccountSync”:72}

有什么帮助吗?? 最大值
插入类别(arrCateData){
让keys=Object.keys(arrCateData[0])
让arrValues=[]
var len=arrCateData.length;
for(设i=0;i{
this.initDB().then((db)=>{
数据库事务((tx)=>{
tx.executeSql(“插入到类别(“+keys+”)值“+字符串(arrValues))。然后(([tx,results])=>{
决心(结果);
});
})。然后((结果)=>{
这个数据库(db);
}).catch((错误)=>{
控制台日志(err);
});
}).catch((错误)=>{
控制台日志(err);
});
});  
}

此代码可能会帮助您我只是将数组传递到函数中,它将根据您的要求插入数据jusr更改数据

您是否尝试在循环中使用async/Wait来确保所有查询都已执行?我对sqlite有一些问题,我创建了insert-fetch-delete函数,但出于某些原因,它没有执行I don’我不工作,你能帮我吗?
db.transaction(
        tx => {
            tx.executeSql("select IDComuniUserAccountSync from ComuniUserAccountSync", [], (a,b) =>
            console.log("!OK!", JSON.stringify(b)), (a,b) =>
            console.log("!ERROR!!", JSON.stringify(b))
    );
        }
    );
insertCategories(arrCateData){


  let keys = Object.keys(arrCateData[0])

  let arrValues = []

    var len = arrCateData.length;



    for (let i = 0; i < len; i++) {
      arrCateData[i].image = `"${arrCateData[i].image}"`;
      arrCateData[i].thumbnail = `"${arrCateData[i].thumbnail}"`;
      arrCateData[i].name = `"${arrCateData[i].name}"`;
      arrCateData[i].path = `"${arrCateData[i].path}"`;
      arrValues.push("(" + Object.values(arrCateData[i]) +")");
    }

    // console.log(arrValues)


  return new Promise((resolve) => {
    this.initDB().then((db) => {
      db.transaction((tx) => {
        tx.executeSql("INSERT INTO category ("+ keys + ") VALUES " + String(arrValues)).then(([tx, results]) => {
          resolve(results);
        });
      }).then((result) => {
        this.closeDatabase(db);
      }).catch((err) => {
        console.log(err);
      });
    }).catch((err) => {
      console.log(err);
    });
  });
