Описание

mixed ingres_query ( resource $link , string $query [, array $params [, string $types ]] )

ingres_query() sends the given query to the Ingres server.

The query becomes part of the currently open transaction. If there is no open transaction, ingres_query() opens a new transaction. To close the transaction, you can call either ingres_commit() to commit the changes made to the database or ingres_rollback() to cancel these changes. When the script ends, any open transaction is rolled back (by calling ingres_rollback()). You can also use ingres_autocommit() before opening a new transaction to have every SQL query immediately committed.

A valid SQL query (see the Ingres SQL reference guide) in the Ingres documentation.

The following types of SQL queries cannot be sent with this function:

close (see ingres_close())
commit (see ingres_commit())
connect (see ingres_connect())

rollback (see ingres_rollback())
savepoint
set autocommit (see ingres_autocommit())
all cursor-related queries are unsupported

params

An array of parameter values to be used with the query

types

A string containing a sequence of types for the parameter values passed. When ingres.describe is enabled, this parameter can be ignored as the driver automatically fetches the expected parameter types from the server.

b	BYTE
B	LONG BYTE/BLOB
c	CHAR
d	DATE/ANSIDATE/TIMESTAMP/TIME
f	FLOAT
i	INTEGER
L	LONG TEXT

Возвращаемые значения

ingres_query() returns a query result identifier when there are rows to fetch else it returns FALSE when there are no rows, as is the case of an INSERT, UPDATE or a DELETE statement. To see if an error occurred use ingres_errno(), ingres_error() or ingres_errsqlstate().

Примеры

Пример #1 Send a simple select


<?php
$link = ingres_connect("demodb");

$result = ingres_query($link, "select * from user_profile");
while ($row = ingres_fetch_row($result)) {
    echo $row[1];
    echo $row[2];
}
?>

Пример #2 Passing query parameters to ingres_query()


<?php
$link = ingres_connect("demodb");

$params[] = "Emma";
$query = "select * from user_profile where up_first = ?";
$result = ingres_query($link, $query, $params);
while ($row = ingres_fetch_row($result)) {
    echo $row[1];
    echo $row[2];
}
?>

Пример #3 Inserting a BLOB with parameter types


<?php
$link = ingres_connect("demodb");

//Open a photo
$fh = fopen("photo.jpg","r");
$blob_data = stream_get_contents($fh);
fclose($fh);

//Prepare parameters
$params[] = $blob_data;
$params[] = 1201;

//Define parameter types
$param_types = "Bi";

$query = "update user_profile set up_image = ? where up_id = ?";
$result = ingres_query($link, $query , $params, $param_types);

if (ingres_errno())
{
    echo ingres_errno() . "-" . ingres_error() . "\n";
}

ingres_commit($link);

ingres_close($link);
?>
