Question

I am performing some DB(SQL) operation in Android using phonegap… Although everything is working fine but then also i am getting unnecessary error while the query executes..This is my code

var db = window.openDatabase("something", "1.0",
                            "PhoneGap Demo", 0);
                    db.transaction(someFunction, errorCB);

function someFunction(tx) {

    tx.executeSql('SELECT md5_value from md5_table where category = 1', [],
            gettingMd5QuerySuccess, errorCB);

}

function gettingMd5QuerySuccess(tx, results) {

        tx.executeSql('UPDATE md5_table set md5_value = "' + tempValue
            + '" where category = 1', successCB, errorCB);

    }

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

What am i doing wrong?

Answer 1

i was doing a syntax error…
I need to replace

tx.executeSql('UPDATE md5_table set md5_value = "' + tempValue
        + '" where category = 1', successCB, errorCB);

By

tx.executeSql('UPDATE md5_table set md5_value = "' + tempValue
        + '" where category = 1', [], successCB, errorCB);
