WHERE id_carrito=?"; if($stmt=$mysqli->prepare($consulta)) { $stmt->bind_param("si",$status,$var); . . . it stops working, vars, are ok i print them after the execute and they have the correct value

Do I need to escape data to protect against SQL injection when using bind_param() on MySQLi?

问题 As the title says, do I have to escape user input when using bind_param() or is that done internally? Thank you. 回答1: No, you do not need to escape data to protect against SQL injection when binding parameters. This does not absolve you from validating said data though. When binding parameters, there is no escaping performed (internally or otherwise). An SQL statement is prepared with parameter placeholders and values for these are passed at execution time. The database knows what parameters

问题 I am trying to call a MySQL server stored procedure using Qt. The procedure returns multiple rows of data I want to retrieve. The first snippet I tried works fine: QSqlQuery query("CALL GetOrderItems(323)", dataBase); qDebug() << query.first(); It also returns the desired data and query.first() is true like expected. Then I tried to insert the parameter using parameter binding like the Qt documentation proposes. I tried the following snippets. The first uses index placeholder the second

Execute sql statement via JDBC with CLOB binding

由 拈花ヽ惹草 提交于 2019-12-08 18:27:27
I have the following query (column log is of type CLOB): UPDATE table SET log=? where id=? The query above works fine when using the setAsciiStream method to put a value longer than 4000 characters into the log column. But instead of replacing the value, I want to append it, hence my query looks like this: UPDATE table SET log=log||?||chr(10) where id=? The above query DOES NOT work any more and I get the following error: java.sql.SQLException: ORA-01461: can bind a LONG value only for insert into a LONG column It looks to me like you have to use a PL/SQL block to do what you want.
