Question

我正在使用phonegap访问手机数据库。但我的创建过程每次调用错误代码时都会调用错误代码：5和消息：non an error？

是不是可以在一个事务中执行多个sql语句？

SQLite Expert无法找到语法错误...

createDB: function(error, success) {
        if(typeof error != 'function') error = this.errorDB;
        if(typeof success != 'function') success = this.successDB;

        console.log(sql);
        this.DB.transaction(function (tx) { tx.executeSql(sql); }, error, success);
    },

不知道错误代码：5但你可以执行多个sql语句

         // Wait for PhoneGap to load

            document.addEventListener("deviceready", onDeviceReady, false);

            // PhoneGap is ready

            function onDeviceReady() {
                var db = window.openDatabase("Database", "1.0", "PhoneGap Demo", 200000);
                db.transaction(populateDB, errorCB, successCB);
            }

            // Populate the database 

            function populateDB(tx) {
                 tx.executeSql('DROP TABLE IF EXISTS DEMO');
                 tx.executeSql('CREATE TABLE IF NOT EXISTS DEMO (id unique, data)');
                 tx.executeSql('INSERT INTO DEMO (id, data) VALUES (1, "First row")');
                 tx.executeSql('INSERT INTO DEMO (id, data) VALUES (2, "Second row")');
        //here you can do  multiple sql statements.
            }

            // Transaction error callback

            function errorCB(err) {
                alert("Error processing SQL: "+err);
            }

            // Transaction success callback

            function successCB() {
                alert("success!");
            }

请从文件资源管理器中检查您的数据库

仅在创建表时出现问题，例如输入四个值但在表中只有三列，因此会出现此错误

tx.executeSql（“CREATE TABLE IF NOT EXISTS引号（id INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT，name，flag INTEGER，address，description，phone_number，date INTEGER，quote_number，job，images）”）;

如果您直接指定整数值而不是var类型值，则会导致错误喜欢flar我使用1或0 但现在我将此值存储在var type

中
