QSqlQuery / bindValue syntax

Hello, this code is working OK :

Code:

---

QSqlQuery query(mybase);
	query.prepare("SELECT name FROM mytable");
 
	if( ! query.exec()  )
		cout << "error SQL= " <<  query.lastError().text().toStdString() << endl;
	else 
		cout << "Ok" << endl;

---

But if I change the 3 lines :

Code:

---

QSqlQuery query(mybase);
	query.prepare("SELECT :tag_array FROM :tag_table");
	query.bindValue(":tag_array","name");
	query.bindValue(":tag_table","mytable");
 
	if( ! query.exec()  )
		cout << "error SQL= " <<  query.lastError().text().toStdString() << endl;
	else 
		cout << "Ok" << endl;

---

I have this error at execution time :

Code:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ':tag_array FROM :tag_table' at line 1 QMYSQL: Unable to execute query

Did I did a mistake ?

Check the documentation for MySQL if the table name in a prepared statement can be a parameter.

You're totaly right Lesiok ! it is not a Qt problem, it is a Mysql problem.
Here is 2 good docs :
