trouble inserting int in mysql

Copy linkTweet thisAlerts:
Nov 23.2006

Hi, i’ve got a problem when trying to insert int data type into mysql. The type of the data is int but sometimes this value is left blank. When the user does not type a value for the field the mysql query fails with a syntax error.

$sql = “INSERT INTO proy (name,date,number) VALUES (‘pete’,’2006-11-22′,)”;

When the user type a value the query does not fail.

Whats the problem?, i have others sql querys in others tables succeding.
Thanks all

$sql = "INSERT INTO proy (name,date,number) VALUES ('pete','2006-11-

22','$number')";

or

$sql = "INSERT INTO proy (name,date) VALUES ('pete','2006-11-22')";

<i>
</i>if($number == '') {
$number = '0';
}

$sql = "INSERT INTO proy (name,date,number) VALUES ('$name','$date','$number')";



This would always force something into the number field assuming that 0 would be OK if nothing was entered by the user.

Thanks you two.

@JayMNov 23.2006 — A more convenient approach is to apply a DEFAULT row column constraint in your mysql table. For example:

<i>
</i>number INT NOT NULL DEFAULT 0,

Let me clarify... when I did this:

<i>
</i>if($number == '') {
$number = '0';
}


I did that to ensure "something" was assigned. Thus the 'quotes'. Mostly out of habit with 0 (zero) because I've coded where some languages treat 0 as null when I really wanted a zero there. Now had I wanted to assign that with any other number or integer, I would have said, for example: $number= 5;

And as for the SQL statement, yes all values there should be like: '$number'

Cheers!
