RE: [PHP-DB] Dynamic SQL + result resource error
Look at this snippet :
$word = current($wordsarray);
next($wordsarray);
$sql=$sql.$word);
if you have 2 words the sql would extend to
word1)word2) .. this is invalid sql syntax.
Change the
while ($i count($wordsarray))
{
$word = current($wordsarray);
next($wordsarray);
$sql=$sql.$word);
$i++;
}
bit into something like this
$sep = ;
foreach( $wordsarray as $v ) {
$sql .= $sep. $word ;
$sep = OR band LIKE ;
}
$sql .= );
Then retry the queries.
oh and yes, include the mysql_query() as Mark Gordon mentioned.

Ha ha... I should have meantioned Here's what it -should- be or
something of the like. :)
I suspect that was the only problem with his code, but perhaps there's
something else there.

Sure he is. Right here:
$queryResult = mysql_query($sql);
what exact error is occurring?

You aren't calling mysql_query() to execute the query.
//$find is text box input
$wordsarray = explode( ,$find);
$sql = SELECT bandname FROM bands WHERE (bandname
LIKE ;
$i = 0;
while ($i count($wordsarray))
{
$word = current($wordsarray);
next($wordsarray);
$sql=$sql.$word);
$i++;
}
print $sqlhr;
$queryResult = mysql_query($sql);
while ($myrow=mysql_fetch_row($queryResult))
{
print $myrow[0],p;
}

Why is this code generating an error when it outputs a
valid SQL statement? (there are no parse errors)
//$find is text box input
$wordsarray = explode( ,$find);
$sql = SELECT bandname FROM bands WHERE (bandname
LIKE ;
$i = 0;

RE: [PHP-DB] Authomatic Sorting
The 'problem' here is the logic of sql databases.
you have one id and one 'username' and they belong to eachother.
id 1 - user 1
id n - user n
meaning if you delete user 23, only id 23 is affected. If you want the
userid 'resorted' you will have to issue a few commands (which also would
destroy the logic of having the id column at all)
alter table mytable drop idcolumn;
alter table mytable add idcolumn unsigned int not null auto_increment
[primary key];
add primary key if it is the primary key.
I would rather suggest you dropped the 001 002 003 column, and used php to
keep count.
example
user001
user002
user0..
user075 (lets say you have 65 users total and that somewhere in 30-50 you
have been deleting)
$res = mysql_query(select username from mytable);
$num = mysql_num_rows($res); // this would give 65
$i = 1;
while($row = mysql_fetch_row($res)) {
echo user id $i - username .$row[0]; $i++;
}
this would print a list from 001 - 065 with every username in it.

Hello guys
I have the following two problems:
I've got a table with an autoincrement field which is the registry's ID,
everything goes well until I delete any registry. MySQL doesn't re-sorts
the information. That is, I have the following:
001 user1
002 user2
003 user3
If I delete user2, I would like to have something as shown next:
001 user1
002 user3
But instead I end up with the following:
001 user1
003 user3
Any idea or comment?

RE: [PHP-DB] sql problem
@a is here an internal 'session' variable used in sql databases (atleast mysql). simple usage : select @a:=1; - 1 select @b:=10; - 10 select @a + @b; - 11 These variables are used to hold temporary numbers and characters, so the interaction between the script language and the database can be held to a minimum.

Your problem here is simply that the $queryresult gets lost in
the function.
It is never returned.
change return true;
into return $queryresult;

Subject: [PHP-DB] Am I missing something important here ?
I have been given an example of how to use php mysql from a hosting
company. They have the following function:
#
function ExecuteQuery ($linkdb, $queryresult, $querytext) {
$queryresult = mysql_query($querytext, $linkdb);
if (($queryresult != false) and (mysql_errno() == 0)) {
return true;
} else {
return false;
}
}
#
And an example of it's usage:
$query = SELECT * FROM test;
if ($mysql_result = mysql_query($query, $linkdb)) {
if (ExecuteQuery($linkdb, $result, $query)) {
while ($row = NextRow($result)) {
print(''.$row[1].' : '.$row[2].'br');
}
}
}
Can anyone tell me why the first if exists in their usage
example, e.g. if
($mysql_result = mysql_query($query, $linkdb)) {
As the $mysql_result variable is not used after this statement
and the query
is performed again in the ExecuteQuery() function;
As I have said, am I missing something important here?
Thanks
