Thank you so much for the advice... I'll look into what stored procedures are now... Maybe that could help me out...

I really appreciate the time you've spent on framing that reply... Thanks a million... Probably by receiving help from people like you, even we, newbies can learn "something" Thanks again...
I'm currently making changes as you suggested in 1 and 2... I think 3 is linked to 2.
Quote:
If only single column is extracted and if you are sure values are there definitely, there is no need for two queries. That could be rewritten something like
Code:
select ip from trace where trace_id >= $i and trace_id <= $i+1;
or even better if you have a running number as column in your table
Code:
select column_with_running_numbers_sequence, ip from trace;
use the above query to fetch all the values in one shot
and now you should have association like
record1 ip_value1
record2 ip_value2
the approach depends upon the table design
Could you kindly elaborate this one? I seem to have missed some simple sql rules... Regarding the table design, I can change it even now because I'm just testing this on 2 million values... The actual data set contains 50 million values...
This 'id' column of trace is an auto_increment... So can I write something like:
Its true that I will be having all the values at once, but how am I gonna compare adjacent values then?
Usually to fetch the rows I use something like:
Thats my problem...
And if I'm not asking too much, I'd like to know about your 4th point too... I've never worked with autocommit... Maybe I'm unknowingly doing that... Is my code potraying that picture by any chance? How can I disable that? Really sorry for the trouble...

Hi All,
I have a problem with my database having lots of 'stale' slow_queries. I think the problem may be because of the following code:

$numrows=mysql_num_rows($numresults);
I believe this... (4 Replies)

Hello,
While I was interpretation the PHP manual on database security the recent past, it said that you should by no means connect to the database as the super user but rather as one more user with more limited options.

ifx_query
IFX_QUERY(3) 1 IFX_QUERY(3)ifx_query - Send Informix querySYNOPSIS
resource ifx_query (string $query, resource $link_identifier, [int $cursor_type], [mixed $blobidarray])
DESCRIPTION
Sends a $query to the currently active database on the server that's associated with the specified link identifier.
For "select-type" queries a cursor is declared and opened. Non-select queries are "execute immediate".
For either query type the number of (estimated or real) affected rows is saved for retrieval by ifx_affected_rows(3).
If the contents of the TEXT (or BYTE) column allow it, you can also use ifx_textasvarchar(1) and ifx_byteasvarchar(1). This allows you to
treat TEXT (or BYTE) columns just as if they were ordinary (but long) VARCHAR columns for select queries, and you don't need to bother with
blob id's.
With ifx_textasvarchar(0) or ifx_byteasvarchar(0) (the default situation), select queries will return BLOB columns as blob id's (integer
value). You can get the value of the blob as a string or file with the blob functions (see below).
PARAMETERS
o $query
- The query string.
o $link_identifier
- The link identifier.
o $cursor_def
- This optional parameter allows you to make this a scroll and/or hold cursor. It's a bitmask and can be either IFX_SCROLL,
IFX_HOLD, or both or'ed together. I you omit this parameter the cursor is a normal sequential cursor.
o $blobidarray
- If you have BLOB (BYTE or TEXT) columns in the query, you can add a $blobidarray parameter containing the corresponding "blob
ids", and you should replace those columns with a "?" in the query text.
RETURN VALUES
Returns valid Informix result identifier on success, or FALSE on errors.
EXAMPLES
Example #1
Show all rows of the "orders" table as a HTML table
<?php
ifx_textasvarchar(1); // use "text mode" for blobs
$res_id = ifx_query("select * from orders", $conn_id);
if (! $res_id) {
printf("Can't select orders : %s
<br />%s<br />
", ifx_error(), ifx_errormsg());
die;
}
ifx_htmltbl_result($res_id, "border="1"");
ifx_free_result($res_id);
?>
Example #2
Insert some values into the "catalog" table
<?php
// create blob id's for a byte and text column
$textid = ifx_create_blob(0, 0, "Text column in memory");
$byteid = ifx_create_blob(1, 0, "Byte column in memory");
// store blob id's in a blobid array
$blobidarray[] = $textid;
$blobidarray[] = $byteid;
// launch query
$query = "insert into catalog (stock_num, manu_code, " .
"cat_descr,cat_picture) values(1,'HRO',?,?)";
$res_id = ifx_query($query, $conn_id, $blobidarray);
if (! $res_id) {
/* ... error ... */
}
// free result id
ifx_free_result($res_id);
?>
