QSQL error on insert into statement

Hi, I'm working on a program where I get user input and insert that value to my database. At the moment, I'm getting the following error:

Quote:

---

QSqlError(-1, "Unable to fetch row", "No query")

---

But I know thats its not my coding because when I try a select statement, it works fine with no problems. My INSERT INTO statement is as follows:

Code:

---

str = pLineEdit->text();
 QString qry = QString("INSERT INTO customer (name, phone_no, address, city) VALUES ('%%1%', NULL, NULL, NULL").arg(str);

---

Is my INSERT statement correct?

Figured it out, syntax wasn't correct, all good and working now!

Good, but seriously take a look at QSqlQuery::prepare() to avoid SQL-Injections.

Got it, thanks!
