ibase_query

(PHP 5, PHP 7 < 7.4.0)

ibase_queryExecuta uma consulta em um banco de dados InterBase

Descrição

ibase_query(resource $link_identifier = ?, string $query, int $bind_args = ?): resource

Executa uma consulta em um banco de dados InterBase.

Parâmetros

link_identifier

Um identificador de conexão InterBase. Se omitido, o da última conexão será utilizado.

query

Uma consulta do InterBase.

bind_args

Valor Retornado

Se houver um erro na consulta, retorna false. Se ela for bem sucedida e houver um conjunto de resultados (possivelmente vazio), como o retornado por uma consulta SELECT, retorna um identificador de resultado. Se a consulta for bem sucedida e não houver resultado, retorna true.

Nota:

No PHP 5.0.0 e posterior, esta função irá retornar o número de linhas afetadas pela consulta para INSERT, UPDATE e DELETE. Para manter a compatibilidade com versões anteriores, irá retornar true para estas consultas se ela for bem sucedida sem afetar nenhuma linha.

Erros/Exceções

Se você tiver um erro como "arithmetic exception, numeric overflow, or string truncation. Cannot transliterate character between character sets" (isto acontece quando você tenta usar alguns caracteres com acentos) ao usar esta função e depois de ibase_query(), deve-se definir o conjunto de caracteres (isto é, ISO8859_1 ou o conjunto de caracteres atual).

Exemplos

Exemplo #1 Exemplo de 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());

?>

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;
}
?>

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);

Contrary to it's description, the function does not always execute the query, unless you try fetching the results. I discovered this through the following code:

<?php
                $result
= ibase_query($dbh,"SELECT boniid FROM PROC_INS_OBONI_DELIV_ADDBONITM ( ? , ? , ? , ? , null , ? )", $bon_id , $plucode2 , $amount , $note $discount);
               
$this->log_add(mb_convert_encoding("SELECT boniid FROM PROC_INS_OBONI_DELIV_ADDBONITM ( " . $bon_id . ", " . $plucode2 . ", " . $amount . ", " . $note . ", " . $nullparent . ", " . $discount . " )",'utf8','cp1251'));

                if (!
$result){
                   
$errmsg = ibase_errmsg();
                   
ibase_rollback($dbh);
                   
ibase_close($dbh);

                   
$this->log_add("Item (" . $mid . " - " . $plucode2 . ") : Error returned (" . __LINE__ . "): " . $errmsg);
                    return
"Error sending product ( $m_name). Error message:  $errmsg";
                }

               
// item data does NOT enter the database if I don't call ibase_fetch_assoc
               
$row = ibase_fetch_assoc($result);
?>

This problem may be limited to FireBird 1.5 or it may not be. Either way, be wary of it.

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 ..."
