Because create is not a valid PHP command. You have to assign the create

$sql = "create table $propTable (

"LgFile text )". :-)

"Limit" is how it's commonly done (though what's "best" really depends on

mysql_query("select foo from bar limit 5,10",$connect) //show ten records

Warning: Undefined index: id in C:\PHP\Test_Scripts\testdb2.php on line 16
1) It's not considered a good habit to use "select *" in scripts. When you
later modify the table defs, your scripts will be blown. Even if you never
add/drop/change a column, it's still messy since whenever you're working on
the code you have to remember--accurately--all of the columns and exactly
(case_sensitive_ what they are named. Yuck. Much cleaner to include the
column names in your query now. "Select id from motor_vehicle"--then you
know for sure you're working with a column of that name.
2) mysql_fetch_array doesn't fetch NULLs. If the value of column 'id' in a
given row is NULL, then $myrow['id'] will be undefined for that row. See
http://php.net/manual/en/function.mysql-fetch-array.php.

From a MySQL perspective, you could adjust the query so no error is
generated. See the syntax for "INSERT IGNORE" or "REPLACE" for instance.
From a PHP perspective, there are functions such as set_error_handler() or
register_shutdown_function() to deal with such issues.

efficient.
Also (since this is part of the problem, I'm sure) how do I take the

Depends. MySQL needs string values quoted too, so if for example all of

$results = "select req, source, number from orders where req='" .
$GLOBALS["req"] . "', source='" . $GLOBALS["source"] . ", number='" .

Re: [PHP-DB] SQL Select?

Is there any way of using a string in an SQL query instead of using the

this doesnt work it come up with a parse error
"SELECT * FROM $tablename" should be sufficient to permit PHP variable
expansion. MySQL will also require a string value to be quoted, so if
$tablename is a string, change the query to "SELECT * FROM '$tablename'".
AFAIK, the missing inner quotes would not cause a PHP parse error, only a
MySQL error. So you may want to look for something else in your code that
could be causing the parse error.

Re: [PHP-DB] Strings

[EMAIL PROTECTED] ("Mick Lloyd") wrote:
Can anyone advise on how to surround a string variable in a query. I select
a string code from a column using:
$result = mysql_query("SELECT * FROM $TA WHERE Profileid = '$profileid'");
$row = mysql_fetch_array($result);
I then want to extract from a second table an id that relates to the code
from the first query. I've tried various combinations of:
$result = mysql_query("select Primaryid from primarycodes where Code =
'$row[Primaryexpertise]'")
Associate array indexes should be quoted:
$row[Primaryexpertise] //not like this
$row['Primaryexpertise'] //like this
$row["Primaryexpertise"] //or like this
Also, even though simple variable references are expanded within
double-quotes (ex. "where Profileid = '$profileid'"), the PHP parser seems
to be less certain about how to deal with array indexes: is the square
bracket intedned as plain text, as a special character (such as in a
regular expression) or is it actually an array index? I find that dropping
out of quotes whenever referencing array indexes eliminates a lot of parse
errors. For example:
"select Primaryid from primarycodes where Code = '" .
$row['Primaryexpertise'] . "'"
Another option is to use extract() so that the array element can be treated
as a simple string variable:
extract($row);
$result = mysql_query("select Primaryid from primarycodes where Code =
'$Primaryexpertise'")
String manipulation has me baffled most of the time!
Re-read the manual's chapters on strings and arrays. Also check out the
Zend site. There are some interesting articles and tutorials over there
that address issues not yet adequately covered in the manual.

Do you mean something like "select if(table1.id 12, table1.id, 'Not')
from foo where somefield='bar'"? Yes, it's possible. See the mysql.com
manual for details.

Yep, because you're using the wrong name(s) for the function known as
"strtoupper" (confusing PHP functions with those of some other language,
perhaps?).
BTW, a quick search of the manual or skim through the list of string
functions would have revealed the problem--and solution--immediately.

Re: [PHP-DB] array awry

This associative array embedded within a function and declared as a global at

this?
If ($Selection == "3")

$tabledata[catid]= $myrow[0];
$tabledata[category] = "$myrow[1]";
$tabledata[under]= $myrow[2];
$tabledata[corder] = $myrow[3];

}
So what you're saying is that want indexes 'catid', 'category', etc. to
have a distinct value for each row pulled from the database? Then you need
to add another dimension to that array.

Are you trying to use '*' as a wildcard character? Because right now, it's
only looking to exclude a file with the exact, literal name '*.php'--not
files like 'anything.php'. Check out the regular expression functions,
either the ereg_* family or preg_*, to do pattern matching.

All that happens when I attempt it is that the text of the include file is
dumped, the connection to the mysql server is not opened and the variables
are not created.
To be parsed as PHP code, the contents of the included file also need to be
in PHP mode ?php ... ?.
