问题描述
我需要知道如何在成功执行 sql 或错误执行失败消息后获取成功消息.我的示例如下
i need to know how to get success message after successful execution of sql or failure message of wrong execution.my example is below
`
public function actionSql()
{
$table_no='1';
$employee='1';
$status='1';
$connection=Yii::app()->db;
$sql="INSERT INTO orders_transaction (table_no,employee,status) VALUES(:table_no,:employee,:status)";
$command=$connection->createCommand($sql);
$command->bindParam(":table_no",$table_no,PDO::PARAM_STR);
$command->bindParam(":employee",$employee,PDO::PARAM_STR);
$command->bindParam(":status",$status,PDO::PARAM_STR);
$command->execute();} `
执行后我需要知道该行是否成功插入.
我使用了下面的一个但没有使用它唯一的回显成功而不是失败
after executing i need to know is the row successfully inserted or not.
i used below one but no use its only echoing successfully not failure
if($command->execute())
{
echo "Successful";
}
else {
echo "ERROR";
}
所以我尝试了这个,它给出了使用密码的本地主机的权限被拒绝错误
so i tried this one its giving permission denied error for localhost with password" "
$result=mysql_query($sql);
// if successfully insert data into database, displays message "Successful".
if($result){
echo "Successful";
}
else {
echo "ERROR";
}
希望你能理解我的问题.请给出任何建议或答案.
i hope you under stand my problem.please give any suggestion or answer.
推荐答案
Execute()
返回受影响的行数(对于 INSERT、DELETE、UPDATE 等).
returns the number of affected rows(for INSERT, DELETE, UPDATE etc).
$num = $command->execute();
此处 $num 将包含受影响的行数.
here $num will contain the affected number of rows.
