The Note You're Voting On

After reading through original notes and example above as well as wading through the documentation, I finally got a loop to work with two stored procedures.

Using the results of the first one as a parameter for the second one. Easier to do this way than a huge modified sequence of Inner Join queries.

Hope this helps others...

<?php
// Connect to server and database
$mysqli        = new mysqli("$dbServer", "$dbUser", "$dbPass", "$dbName");

// Open First Stored Procedure using MYSQLI_STORE_RESULT to retain for looping
$resultPicks = $mysqli->query("CALL $proc ($searchDate, $maxRSI, $incRSI, $minMACD, $minVol, $minTrades, $minClose, $maxClose)", MYSQLI_STORE_RESULT);

// process one row at a time from first SP
while($picksRow = $resultPicks->fetch_array(MYSQLI_ASSOC)) {
    // Get Parameter for next SP
    $symbol     = $picksRow['Symbol'];

    // Free stored results
    clearStoredResults($mysqli);

    // Execute second SP using value from first as a parameter (MYSQLI_USE_RESULT and free result right away)
    $resultData    = $mysqli->query("CALL prcGetLastMACDDatesBelowZero('$symbol', $searchDate)", MYSQLI_USE_RESULT);
    $dataRow    = $resultData->fetch_array(MYSQLI_ASSOC);

    // Dump result from both related queries
    echo "<p>$symbol ... Num Dates: " . $dataRow['NumDates'];

    // Free results from second SP
    $resultData->free();

}

// Free results from first SP
$resultPicks->free();

// close connections
$mysqli->close();

#------------------------------------------
function clearStoredResults($mysqli_link){
#------------------------------------------
    while($mysqli_link->next_result()){
      if($l_result = $mysqli_link->store_result()){
              $l_result->free();
      }
    }
}
?>
