[Solved] error while inserting row in table (QSql)

[ashishbansal]

Hello everyone,

I am getting error while trying to insert row into table.
Code for creating table :
@
QSqlDatabase mydb = QSqlDatabase::addDatabase("QSQLITE");
mydb.setDatabaseName("dmDownloadList");
QSqlQuery qry(mydb);
QString qryStr = "create table if not exists downloadList(id integer, filename varchar)";
if(!qry.exec(qryStr)){
qDebug() << "Unable to create table!";
qDebug() << qry.lastError();
}else{
qDebug() << "Table successfully created";
}
@
Output : Table Successfully created
But while inserting row,
Code For Inserting row in table:
@
QSqlQuery qry(mydb);
QString qryStr = "insert into downloadList (id, filename) values (:id, :filename)";
qry.prepare(qryStr);
qry.bindValue(":id", 1);
qry.bindValue(":filename", "foo");
if(!qry.exec(qryStr)){
qDebug() << "Unable to insert row in table!";
qDebug() << qry.lastError();
}
@
Unable to insert row in table!
QSqlError("", "Parameter count mismatch", "")

Parameter count is correct then why I am getting this error? :/

Am I really doing some very silly mistake?
Anyone with any suggestion or something which can help me in debugging it?

Ah, after several hours of banging head with wall, It finally got solved!
My mistake was that I was passing parameter to QSqlQuery.
I don't have to pass string parameter to QSqlQuery::exec after preparing query using QSqlQuery::prepare.
Huh!!
