ibase_fetch_row

(PHP 5)

ibase_fetch_rowRecuperar una fila desde una base de datos InterBase

Descripción

array ibase_fetch_row ( resource $result_identifier [, int $fetch_flag = 0 ] )

ibase_fetch_row() recupera una fila de datos desde el conjunto de resultados dado.

Las llamadas subsiguientes a ibase_fetch_row() devuelven la siguiente fila en el conjunto de resultados, o FALSE si no hay más filas.

Parámetros

result_identifier

Un identificador de resultado InterBase.

fetch_flag

fetch_flag es una combinación de las constantes IBASE_TEXT y IBASE_UNIXTIME unidas con el operador lógico OR. Al pasar IBASE_TEXT, esta función devuelve contenidos BLOB en lugar de identificadores BLOB. Al pasar IBASE_UNIXTIME, esta función devuelve valores de fecha/hora como marcas de tiempo Unix en lugar de cadenas con formato.

Valores devueltos

Devuelve un array que corresponde a la fila recuperada, o FALSE si no hay más filas. Cada columna del resultado es almacenado en una posición del array, comenzando en 0.

If you have a query

"select ... from table1 where ..."

and would like to know the cardinality of the result set by issuing a separate query

"select count(*) from table1 where ..."

then you might end up with an incorrect value since an insert or delete can occur between the running of these queries (unlikely, but possible).
The only way i can think of getting the correct value would be something along the lines of

<?php

$qry
= "select ... from table1 where ...";
$result = ibase_query($tr, $qry) // assume $tr is a transaction

$count = 0;
while (
$row[$count] = ibase_fetch_assoc($result))
   
$count++;

?>

then $count is the cardinality, and $row the result set.
Then you can work with the result set:

<?php

for ($i = 0; $i < $count; $i++)
{
 
// do something with $row[$i]
}

?>

I had some troubles with moving php application from one dbase to another. From SyBase to Interbase.
Especially with missing function "ibase_num_rows($result)".

These are functions that helped me.
<?php
...
$dbh = ibase_connect ($host, $username, $password);
...
$ar_count_queries = array();

function
ibasequery($query) {
 
$cquery = preg_replace("/SELECT(.*?)FROM(.*?)/","SELECT COUNT(*) FROM \\2",$query);
  if (
$cquery != $query) {
  
$crow=get_object_vars( ibase_fetch_object( ibase_query( $GLOBALS["dbh"], $cquery ) ) );
   }
  @
$res = ibase_query($GLOBALS["dbh"],$query);
  if (isset(
$res)) {
    if (isset(
$crow)) {
    
$GLOBALS["ar_count_queries"][$res] = $radcountselect["COUNT"];
    }
    return
$res;
  }
   return
false;
}

function
ibasenumrows($result) {
  return
$GLOBALS["ar_count_queries"][$res];
}

function
ibasefetchrow($result) {
  return
get_object_vars(ibase_fetch_object($result));
}

// example
$result = ibasequery("SELECT * FROM TABLE");
$numrows = ibasenumrows($result);
echo
"Number of rows: $numrows.\nContent: \n";
while (
$onerow = ibasefetchrow($res)) {
  foreach(
$onerow as $key => $value) {
    echo
$key.": ".$value.", ";
  }
  echo
"\n";
}
?>
