ibase_query

(PHP 4, PHP 5)

ibase_queryExécute une requête sur une base iBase

Description

resource ibase_query ([ resource $link_identifier ], string $query [, int $bind_args ] )

Exécute une requête sur une base iBase.

Liste de paramètres

link_identifier

Un identifiant de connexion à InterBase. S'il est omis, la dernière connexion ouverte sera utilisée.

query

Une requête InterBase.

bind_args

Valeurs de retour

Si la requête émet une erreur, la fonction retournera FALSE. Si la requête est exécutée avec succès, et qu'il y a un jeu de résultats (même vide), la fonction retournera un identifiant de résultat. Si la requête est exécutée avec succès, et qu'il n'y a pas de résultat, la fonction retournera TRUE.

Note: Dans les version 5.0.0 de PHP et suivantes, ibase_query() retourne le nombre d'enregistrements affectés par les requêtes INSERT, UPDATE et DELETE. Dans un souci de compatibilité ascendante, ibase_query() retournera TRUE si la requête réussi mais ne renvoie aucun enregistrement.

Erreurs / Exceptions

Si vous recevez une erreur du type "arithmetic exception, numeric overflow, or string truncation. Cannot transliterate character between character sets" (ceci survient lorsque vous essayez d'utiliser des caractères accentués) avec la fonction ibase_query(), c'est que vous devez choisir un jeu de caractères (i.e. ISO8859_1 ou votre jeu courant).

Exemples

Exemple #1 Exemple avec ibase_query()

<?php

$host 
'localhost:/path/to/your.gdb';

$dbh ibase_connect($host$username$password);
$stmt 'SELECT * FROM tblname';

$sth ibase_query($dbh$stmt) or die(ibase_errmsg());

?>

In woking time ibase_qury() and ibase_fetch_row() with many time call thei arise the ERROR -> Fatal error: Maximum execution time of 30 seconds exceeded

ERROR arise in that script:
foreach ($vidtr_list as $vidtr)
{
   foreach ($branches_train as $from)
   {
     foreach ($branches_train as $to)
     {
       if (isset($pricelst_train[$vidtr][$from][$to]['ID']))
       {
    for ($i = 1; $i < 7; $i++)
    {
      $id = $pricelst_train[$vidtr][$from][$to]['ID'];
               $sql_v = "SELECT * FROM P_GET_PRICE_C_VES('$id','$std_train1_ves[$i]')";
      $query_rez = ibase_query($db,$sql_v) or die(ibase_errmsg());
      $prc_v =  ibase_fetch_row($query_rez);
      $sql_o = "SELECT * FROM P_GET_PRICE_C_OBYOM('$id', '$std_train1_obyom[$i]')";
       $query_rez = ibase_query($db,$sql_o) or die(ibase_errmsg());
      $prc_o =  ibase_fetch_row($query_rez);
                   
    if (isset($prc_o[0]))
    {
    $c_obyom = $prc_o[0];
    $c_ves = $prc_v[0];
    $prices_train[$id][$i] = array( 'OBYOM' => $c_obyom,'VES'    => $c_ves );
    $mysql_jde_price[$cnt_price] = "INSERT INTO jde_price VALUES (default, '$id', '$std_train1_ves[$i]', '$c_ves', '$std_train1_obyom[$i]', '$c_obyom');";
    $cnt_price++;
    }
    }
   }
  }
 }
}

How I can decide that Error?

If you use ibase_query() for SELECT without fetching result then you must know that SELECT isn't actually executed.
E.g. you perform "SELECT MY_UDF(param) from RDB$DATABASE" - MY_UDF isn't actually called until you fetch result.

This is a feature(or bug) of php interbase drivers, not interbase/firebird itself.

Test conditions: firebird 1.5.2, php 4.

Simple function to retrieve the results of an SQL statement into an array, will also cater for BLOB fields:

<?php
function interbase_sql_exec ($sql) {
   
$dataArr = array();
   
$host = "svrname:path\filename.GDB";
   
$username = "whatever";
   
$password = "******";
   
$connection = ibase_connect ($host, $username, $password,'ISO8859_1', '100', '1');
   
$rid = @ibase_query ($connection, $sql);
    if (
$rid===false) errorHandle(ibase_errmsg(),$sql);
   
$coln = ibase_num_fields($rid);
   
$blobFields = array();
    for (
$i=0; $i < $coln; $i++) {
       
$col_info = ibase_field_info($rid, $i);
        if (
$col_info["type"]=="BLOB") $blobFields[$i] = $col_info["name"];
    }
    while (
$row = ibase_fetch_row ($rid)) {
        foreach (
$blobFields as $field_num=>$field_name) {
           
$blobid = ibase_blob_open($row[$field_num]);
           
$row[$field_num] = ibase_blob_get($blobid,102400);
           
ibase_blob_close($blobid);
        }
       
$dataArr[] = $row;
    }
   
ibase_close ($connection);
    return
$dataArr;
}
?>

Two comments on interogating system tables in Interbase or Firebird; I hope it helps.

1. if you try to build a query string to extract data from a system table (that has the form "rdb$some_name"), you should divide the "rdb$some_name" table name in your query string using the string merge operator ".".
$query = "select rdb"."$"."relation_name as TABLE_NAME from rdb"."$"."relations where rdb"."$"."system_flag=0";

2. The second thing is related to the fact that you can later use (after the call to ibase_fetch_object) as field identifier the ALIAS used in the query for the "rdb$some_name" table.

Example:
$get_table_names_query = "select rdb"."$"."relation_name as TABLE_NAME from rdb"."$"."relations where rdb"."$"."system_flag=0";
//
$res_table_names_query = ibase_query($dbconnection, $get_table_names_query);
//
while ($row_table_names = ibase_fetch_object($res_table_names_query))
{
    print($row_table_names->TABLE_NAME);//alias used
}

Editor's note:
it is easier to use a backslash to protect the $-sign.
eg. "select rdb\$relation_name as TABLE_NAME from ..."

A BLOB can be fetched easily adding IBASE_TEXT parameter to the ibase_fetch_object() function:

$r=ibase_query("select BLOB from BLOBS where BLOB_ID=1");
$d=ibase_fetch_object($r,IBASE_TEXT);

and it will fetch the BLOB as a text. Thus it referres to it like this:
$d->BLOB

Using BLOB

Insert BLOB:

 /* create blob */
$blob_id = ibase_blob_create();

 /* fill blob */
ibase_blob_add($blob_id, $var_datablob);

/* close new blob */
$blob_id_str = ibase_blob_close($blob_id);

/* insert into table  */
ibase_query("INSERT INTO BLOB_TABLE (ID, BLOB) VALUES (1, ?)",$blob_id_str);

Open BLOB:

/* query */
$set = ibase_query("SELECT BLOB FROM BLOB_TABLE WHERE ID = 1");

/* fetche a row */
$row = ibase_fetch_object($set);

/* open BLOB for read */
$blob_id = ibase_blob_open($row->BLOB);

/* get BLOB data */
$stringBLOB = ibase_blob_get($blob_id);

/* print BLOB */
echo $stringBLOB;

/* close new blob */
ibase_blob_close($blob_id);

/* free result */
ibase_free_result($set);
