But, all i need is to get the average on col3 based on col1 and col4 based on col2. I need the result like the below.
Code:
COL1 COL2 COL3
1 500 500
2 290 290
3 100 100

Within your sample result, COL3 is not the average on col4 based on col2 but the sum of col4 based on col1.

From your requirement, I don't understand how you can mix in the same output value of col1, average based on col1 and average base on col2.

maxdb_stmt_bind_result - Binds variables to a prepared statement for result storage

       Procedural style

SYNOPSIS
bool maxdb_stmt_bind_result (resource $stmt, mixed &$var1, [mixed &$...]) DESCRIPTION
Object oriented style bool maxdb_stmt::bind_result (mixed &$var1, [mixed &$...]) maxdb_stmt_bind_result(3) is used to associate (bind) columns in the result set to variables. When maxdb_stmt_fetch(3) is called to fetch data, the MaxDB client/server protocol places the data for the bound columns into the specified variables $var1, .... Note Note that all columns must be bound prior to calling maxdb_stmt_fetch(3). Depending on column types bound variables can silently change to the corresponding PHP type. A column can be bound or rebound at any time, even after a result set has been partially retrieved. The new binding takes effect the next time maxdb_stmt_fetch(3) is called. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 Object oriented style <?php $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB"); if (maxdb_connect_errno()) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } /* prepare statement */ if ($stmt = $maxdb->prepare("SELECT zip, name FROM hotel.city ORDER BY name")) { $stmt->execute(); /* bind variables to prepared statement */ $stmt->bind_result($col1, $col2); /* fetch values */ while ($stmt->fetch()) { printf("%s %s ", $col1, $col2); } /* close statement */ $stmt->close(); } /* close connection */ $maxdb->close(); ?> Example #2 Procedural style <?php $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (!$link) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } /* prepare statement */ if ($stmt = maxdb_prepare($link, "SELECT zip, name FROM hotel.city ORDER BY name")) { maxdb_stmt_execute($stmt); /* bind variables to prepared statement */ maxdb_stmt_bind_result($stmt, $col1, $col2); /* fetch values */ while (maxdb_stmt_fetch($stmt)) { printf("%s %s ", $col1, $col2); } /* close statement */ maxdb_stmt_close($stmt); } /* close connection */ maxdb_close($link); ?> The above example will output something similar to: 12203 Albany 60601 Chicago 60615 Chicago 45211 Cincinnati 33575 Clearwater 75243 Dallas 32018 Daytona Beach 33441 Deerfield Beach 48226 Detroit 90029 Hollywood 92714 Irvine 90804 Long Beach 11788 Long Island 90018 Los Angeles 70112 New Orleans 10019 New York 10580 New York 92262 Palm Springs 97213 Portland 60018 Rosemont 95054 Santa Clara 20903 Silver Spring 20005 Washington 20019 Washington 20037 Washington SEE ALSO
