`I am using MS SQL Server 2005, and using odbc_connect with SQL_CUR_USE_ODBC.
I had a problem with odbc_fetch_array when getting results from a stored procedure that returns a text column. The misleading error I got was:
odbc_fetch_array() [function.odbc-fetch-array]: SQL error: [Microsoft][ODBC Cursor Library] Result set was not generated by a SELECT statement, SQL state SL004 in SQLGetData
Eventually I found that by converting the text column in my database to varchar(8000), it worked fine. Perhaps using CONVERT or CAST might have worked too. I also found that varchar(max) columns were scrambled.`

$arr=dbquery($dbsel);
echo $arr[1][1]."<br>";//echo's first column of the first row
echo $arr[1][2]."<br>";

I believe it has something to do with sprintf line? Even tho echoing it returns the right SELECT statement.
any help would rock thanx`

`Depending on the odbc driver/operating system you are using, odbc_fetch_array might not be defined. (ie if you used --with-custom-odbc you may be out of luck). The following can be safely added to define the odbc_fetch_array function if doesn't exist already. Unlike some of the other examples contributed here, this one will create the numeric keys and the text keys. This function is definitely not very optimal because it has to check the number of fields and field names each time a row is pulled. Often you will be looping through a result set and there is no need to pull this information each time. It could probably be improved by caching the result of these functions but I'll leave that as an exercise for someone else... :)
if(!function_exists("odbc_fetch_array"))
{
function odbc_fetch_array($res)
{
// make sure to pass back the false if we are out of rows
if(!odbc_fetch_row($res)) return false;
$row=array();
// populate the row array
$numfields=odbc_num_fields($res);
for($i=1; $i<=$numfields; $i++)
{
//odbc starts its indice at 1 but since I am
// trying to emulate the functionality of *_fetch_array
// for other dbs (ie mysql) I'm going to decrement my
// my numeric indice by 1. This might not be what
// you are after in which case get rid of the -1
$row[odbc_field_name($res,$i)]=$row[$i-1]=odbc_result($res,$i);
}
return $row;

`This function is undefined in 4.1.2 (RedHat 7.3) despite the claims of the documentation.
It's just too useful a function not to have, particularly if your database is prone to change. Here's my quick and dirty version:

{
$array=array(); // Truncate the array first...
if (! $int = odbc_fetch_into ($resource, $result_array))

`In response to Sena's post, odbc_num_rows does not always return a row count. When executing a query on MS Access it seems to return a row count of -1.
<?php
while(odbc_num_rows($myodbcexec)){
$myarray[] = odbc_fetch_array($myodbcexec);

Just something to watch out for when attempting to execute this code.

usage is pretty simple:

Works pretty well, but I haven't thoughly tested it yet.

`It all seems so obvious now, but in case you're stuck on how to get the entire ODBC query into one array, instead of just one line, this will do the trick:
<?php
while(odbc_num_rows($myodbcexec)){
$myarray[] = odbc_fetch_array($myodbcexec);

`Heya,
After much fiddling around with the odbc_num_rows() function, and trying to get odbc_fetch_array() to play nice with it, I decided to write this little function which will return a 2-dimensional array, in the format [rownumber][field].
The 'rownumber' array index is obviously the number of the row stored in the array.
The 'field' index is keyed to the field name on that row.
--Function--
<?
function fetch2DArray($res){
$i = 0;
$j = 0;
$toReturn = "";
while(odbc_fetch_row($res))
{
for ($j = 1; $j <= odbc_num_fields($res); $j++)
{
$field_name = odbc_field_name($res, $j);
$ar[$field_name] = odbc_result($res, $field_name);
}
$toReturn[$i] = $ar;
$i++;
}
return $toReturn;
}
?>
I then took this one stage further.. and wrote a whole class to deal with the odbc connection... it's a bit slap-happy, but it does work well enough.
-- Class --
<?
class odbcConnection{
var $user; //Username for the database
var $pass; //Password
var $conn_handle; //Connection handle
var $temp_fieldnames; //Tempory array used to store the fieldnames, makes parsing returned data easier.
function odbcConnection(){
$this->user = "";
$this->pass = "";
}
function connectDatabase($dsn_link,$user,$pass){
$handle = @odbc_connect($dsn_link,$user,$pass,SQL_CUR_USE_DRIVER) or die("<B>Error!</B> Couldn't Connect To Database. Error Code: ".odbc_error());
$this->conn_handle = $handle;
return true;
}
function runStoredQuery($query, $returns_results){
if($returns_results == false){
return false;
}
$toReturn = "";
$res = @odbc_exec($this->conn_handle, "exec ".$query."") or die("<B>Error!</B> Couldn't Run Stored Query. Error Code: ".odbc_error());
unset($this->temp_fieldnames);
$i = 0;
$j = 0;
while(odbc_fetch_row($res))
{
//Build tempory
for ($j = 1; $j <= odbc_num_fields($res); $j++)
{
$field_name = odbc_field_name($res, $j);
$this->temp_fieldnames[$j] = $field_name;
$this->temp_fieldnames[$j];
$ar[$field_name] = odbc_result($res, $field_name);
}
$toReturn[$i] = $ar;
$i++;
}
return $toReturn;
}
function runSQL($query,$returns_results){
$toReturn = "";
$res = @odbc_exec($this->conn_handle,$query) or die("<B>Error!</B> Couldn't Run Query. Error Code: ".odbc_error());
unset($this->temp_fieldnames);
if($returns_results == false){
return false;
}
$i = 0;
$j = 0;
while(odbc_fetch_row($res))
{
//Build tempory
for ($j = 1; $j <= odbc_num_fields($res); $j++)
{
$field_name = odbc_field_name($res, $j);
$this->temp_fieldnames[$j] = $field_name;
$ar[$field_name] = odbc_result($res, $field_name);
}
$toReturn[$i] = $ar;
$i++;
}
return $toReturn;
}
}
//And an example of how to use the class:
include("dbClass.inc"); //Where dbClass.inc is the name of the file holding the class
//Declare a new instance of the class
$dbConnection = new odbcConnection;
$dsn = "GroupWork"; //Your System DSN name to point to your database
$dbConnection->connectDatabase($dsn,"",""); //No username and password - read only access
echo"<BR><HR><B>Testing SQL</b><BR><BR>";
$query_result = $dbConnection->runSQL("SELECT * FROM Event WHERE Type = 'Sport' ORDER BY EDate ASC",true);
if(!$query_result)
{
//No Results - Your Error Code Here
}else{
//Get the results
$key = $dbConnection->temp_fieldnames;
$rows = count($query_result);
$keys = count($key);
$i = 0;
while($i < $rows){
$j = 1;
echo "Echoing Row $i:<BR>";
while($j < $keys - 1){
//$query_result[row][field];
$result = $query_result[$i][$key[$j]];
$field = $key[$j];
echo("Field <b>'".$field."'</b> : ".$result." <BR>");
$j++;
}
echo "<BR>----<BR><BR>";
$i++;
}
}
?>
Hope this was of some help. If anyone has any improvments to the class, please drop them by me.`

`This function is badly implemented, because the fetch_array versions for all other databases are storing the values as associative AND numeric key.
This one only stores as associative key :(
Someone should really cleanup the complete database api design!`

`This is a quick and dirty way to accomplish the same thing:
<?
while(odbc_fetch_row($result)) {
$var1 = odbc_result($result, "NAMEOFFIELD1");
$var2 = odbc_result($result, "NAMEOFFIELD2");
..... //as many vars as you have fields with data to capture
$array_of_results[] = compact('var1', 'var2','var3', etc, etc)
}
?>
Just turn each returned row's data into variables then use the compact(). Turns each variable name into a key and the vars value into the array value. Makes a wonderful 2d array that you can walk easily and still use key values to get at data.`

`Using odbc_fetch_into() is becoming tiresome when it had to be changed in php version 4.0.5, 4.0.6 and 4.2.x. Also, using define() function no longer work well with 4.2.x, so define() is not reliable for odbc_fetch_into(). Time on the job to keep up with the changes is ill-advised. Turned out the better solution is to use odbc_fetch_array and not have to deal with the hassle of updating the database, web pages, etc. It is worth the time in the long run.

This is pretty useful when we keep adding columns to the database table. If you combine two tables and have two columns with the same column name, then you'll need to have two seperate array, like $user_detail1 and $user_detail2, etc. Whatever you can come up with.`

`Just a note about the odbc_fetch_array function of Martin (above).
The function actually works fine except when your resultset is empty (where $rs_assoc is not defined).
To avoid this just define $rs_assoc as an array before the foreach like this :
$rs_assoc = Array();
That should do the trick`
