我怎樣才能SQLite中插入變量的值,我無法找到問題,我的代碼,如果我使用INSERT語句如下這是工作和值插入,問題與SQLite中插入查詢?(可變插入)
tx.executeSql('INSERT INTO Locationlog (Coordinates, Location, Category, Address) VALUES ("manju", "kishor", "ramesh", "ram")');
如果我嘗試插入如下值沒有被插入,
tx.executeSql('INSERT INTO Locationlog (Coordinates, Location, Category, Address) VALUES (?,?,?,?)',[Latlongs,Location,Category,Address]);
不用於查詢像工作,
tx.executeSql('INSERT INTO Locationlog (Coordinates, Location, Category, Address) VALUES ('+Latlongs+', '+Location+', '+Category+', '+Address+')');
我對所有列使用TEXT作爲數據類型,輸入值大小在1-100之間。 TEXT數據類型的最大大小是多少?任何人都可以建議如何在插入查詢中插入變量?
var Latlongs = $("#defendLatlongs").val();
var Location = $("#defendLocation").val();
var Category = $("#defendcategory").val();
var Address = $("#defendAddress").val();
var db = window.sqlitePlugin.openDatabase({name: "MYDB"});
db.transaction(function (tx) {
tx.executeSql('CREATE TABLE IF NOT EXISTS Locationlog (Coordinates TEXT, Location TEXT, Category TEXT, Address TEXT)');
});
db.transaction(function (tx){
tx.executeSql('INSERT INTO Locationlog (Coordinates, Location, Category, Address) VALUES (?,?,?,?)',[Latlongs,Location,Category,Address]);
});
});
