If someone wants to read my solution for SQLite in Cordova, I got this generic js method thanks to @david answer above.
function addOrUpdateRecords(tableName, values, callback) {
get_columnNames(tableName, function (data) {
var columnNames = data;
myDb.transaction(function (transaction) {
var query_update = "";
var query_insert = "";
var update_string = "UPDATE " + tableName + " SET ";
var insert_string = "INSERT INTO " + tableName + " SELECT ";
myDb.transaction(function (transaction) {
// Data from the array [[data1, ... datan],[()],[()]...]:
$.each(values, function (index1, value1) {
var sel_str = "";
var upd_str = "";
var remoteid = "";
$.each(value1, function (index2, value2) {
if (index2 == 0) remoteid = value2;
upd_str = upd_str + columnNames[index2] + "='" + value2 + "', ";
sel_str = sel_str + "'" + value2 + "', ";
});
sel_str = sel_str.substr(0, sel_str.length - 2);
sel_str = sel_str + " WHERE NOT EXISTS(SELECT changes() AS change FROM "+tableName+" WHERE change <> 0);";
upd_str = upd_str.substr(0, upd_str.length - 2);
upd_str = upd_str + " WHERE remoteid = '" + remoteid + "';";
query_update = update_string + upd_str;
query_insert = insert_string + sel_str;
// Start transaction:
transaction.executeSql(query_update);
transaction.executeSql(query_insert);
});
}, function (error) {
callback("Error: " + error);
}, function () {
callback("Success");
});
});
});
}
So, first pick up the column names with this function:
function get_columnNames(tableName, callback) {
myDb.transaction(function (transaction) {
var query_exec = "SELECT name, sql FROM sqlite_master WHERE type='table' AND name ='" + tableName + "'";
transaction.executeSql(query_exec, [], function (tx, results) {
var columnParts = results.rows.item(0).sql.replace(/^[^\(]+\(([^\)]+)\)/g, '$1').split(','); ///// RegEx
var columnNames = [];
for (i in columnParts) {
if (typeof columnParts[i] === 'string')
columnNames.push(columnParts[i].split(" ")[0]);
};
callback(columnNames);
});
});
}
Then build the transactions programmatically.
"Values" is an array you should build before and it represents the rows you want to insert or update into the table.
"remoteid" is the id I used as a reference, since I'm syncing with my remote server.
