ibase_query Führt eine Abfrage (Query) auf eine InterBase-DB aus


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

Erzeugt eine Anfrage auf eine InterBase-DB, deren Ergebnis mit ibase_fetch_row(), ibase_fetch_object(), ibase_free_result() und ibase_free_query() weiter verarbeitet werden kann.


Obwohl diese Funktion auch die Verwendung von Platzhaltern unterstützt, ist ihr keine besondere Bedeutung beizumessen. Für reale Abfragen und Beispiele sehen sie unter ibase_prepare() und ibase_execute() nach.

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');";

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:

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);
$dataArr[] = $row;
ibase_close ($connection);

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.

$get_table_names_query = "select rdb"."$"."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");

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

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 */

/* free result */
