Question

pretty simple code in php and mysql:

code inserting data in mysql table :

<?php

include("config.php");

$sql="INSERT INTO messages_sent (to) VALUES (35)";

$result=mysql_query($sql);

if(!$result)
{
    echo("<br>Sorry the message could not be inserted into table messages_sent</br><br>");
    die(mysql_error());     
}else{      
    echo("<br>Message Inserted</br>");
}    

?>

table creation code follows:

$sql="CREATE TABLE IF NOT EXISTS `messages_sent`(
`id` INT(11) NOT NULL AUTO_INCREMENT PRIMARY KEY,
`to` INT(11) NOT NULL,
`from` INT(11) NOT NULL,
`msg` TEXT NOT NULL,
`viewed` TINYINT(2)NOT NULL,
`time` DATETIME NOT NULL
)";

$result=mysql_query($sql);

if(!$result)
{
    echo("Sorry the create query for table messages_sent could not be executed ");
    die(mysql_error());     
}

if i insert data in msg column, it is no prob but if the column is to or from then syntax error problem occurs.

Solution?

Answer 1

in the schema of your table, you are setting NOT NULL with none DEFAULT value to other fields. so basically you cannot execute

INSERT INTO messages_sent (to) VALUES (35)

because you are leaving other fields NULL and ALSO FROM and TO are Reserved Word in mySQL. Or instead use back ticks ` inside your query.

ex.

INSERT INTO `tableName` (`colName`) VALUES (valueHere)
