PHP Manual: Send an SQL query to Ingres

Description

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.

Parameters

link

The connection link identifier.

query

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

Data inside the query should be properly escaped.

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

close (see ingres_close)
commit (see ingres_commit)
connect (see ingres_connect)
disconnect (see ingres_close)
get dbevent
prepare to commit
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.

Type code	Ingres type
a	BOOLEAN
b	BYTE
B	LONG BYTE/BLOB
c	CHAR
d	DATE/ANSIDATE/TIMESTAMP/TIME
f	FLOAT
i	INTEGER
L	LONG TEXT
m	MONEY
M	LONG NVARCHAR
n	NCHAR
N	NVARCHAR
t	TEXT
v	VARCHAR
V	LONG VARCHAR

Return Values

ingres_query returns a query result identifier on success else it returns FALSE. To see if an error occurred use ingres_errno, ingres_error or ingres_errsqlstate.

Examples

Example #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];
}
?>

Example #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];
}
?>

Example #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);
?>
