ibase_query

(PHP 5, PHP 7 < 7.4.0)

ibase_query — InterBase データベースでクエリを実行する

説明

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

InterBase データベース上でクエリを実行します。

パラメータ

link_identifier: InterBase リンク ID。省略した場合は、最後にオープンしたリンクを使用します。
query: InterBase クエリ。
bind_args

戻り値

クエリが失敗した場合、false を返します。成功した場合、 (SELECT クエリのような) 結果の行がある場合、結果 ID を返します。クエリが成功し、結果がない場合は true を返します。

注意:
PHP 5.0.0 以降では、INSERT・UPDATE・DELETE 文に対してはこの関数は変更された行数を返します。後方互換性を確保するため、これらの文でクエリが成功したものの 1 行も更新されなかった場合には true を返します。

エラー / 例外

ibase_query() の実行後に "arithmetic exception, numeric overflow, or string truncation. Cannot transliterate character between character sets" のようなエラーに遭遇した場合 (アクセント記号つきの文字を使用した場合などに起こります)、文字セットを(ISO8859_1 あるいは現在の文字セットに)設定する必要があります。

例

例1 ibase_query() の例

<?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());

?>

参考

ibase_errmsg() - エラーメッセージを返す
ibase_fetch_row() - InterBase データベースから 1 行分の結果を取得する
ibase_fetch_object() - InterBase データベースからオブジェクトを得る
ibase_free_result() - 結果セットを解放する

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);

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 ..."

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.
