db2_execute

The following example prepares an INSERT statement that accepts four parameter markers, then iterates over an array of arrays containing the input values to be passed to db2_execute().

<?php
$pet = array(0, 'cat', 'Pook', 3.2);

$insert = 'INSERT INTO animals (id, breed, name, weight)
    VALUES (?, ?, ?, ?)';

$stmt = db2_prepare($conn, $insert);
if ($stmt) {
    $result = db2_execute($stmt, $pet);
    if ($result) {
        print "Successfully added new pet.";
    }
}
?>

The above example will output:

The following example prepares a CALL statement that accepts one parameter marker representing an OUT parameter, binds the PHP variable $my_pets to the parameter using db2_bind_param(), then issues db2_execute() to execute the CALL statement. After the CALL to the stored procedure has been made, the value of $num_pets changes to reflect the value returned by the stored procedure for that OUT parameter.

<?php
$num_pets = 0;
$res = db2_prepare($conn, "CALL count_my_pets(?)");
$rc = db2_bind_param($res, 1, "num_pets", DB2_PARAM_OUT);
$rc = db2_execute($res);
print "I have $num_pets pets!";
?>

The following example demonstrates how to work with documents stored in a XML column using the SAMPLE database. Using some pretty simple SQL/XML, this example returns some of the nodes in a XML document in an SQL ResultSet format that most users are familiar with.

<?php

$conn = db2_connect("SAMPLE", "db2inst1", "ibmdb2");

$query = 'SELECT * FROM XMLTABLE(
    XMLNAMESPACES (DEFAULT \'http://posample.org\'),
    \'db2-fn:xmlcolumn("CUSTOMER.INFO")/customerinfo\'
    COLUMNS
    "CID" VARCHAR (50) PATH \'@Cid\',
    "NAME" VARCHAR (50) PATH \'name\',
    "PHONE" VARCHAR (50) PATH \'phone [ @type = "work"]\'
    ) AS T
    WHERE NAME = ?
    ';

$stmt = db2_prepare($conn, $query);

$name = 'Kathy Smith';

if ($stmt) {
    db2_bind_param($stmt, 1, "name", DB2_PARAM_IN);
    db2_execute($stmt);

    while($row = db2_fetch_object($stmt)){
    printf("$row->CID     $row->NAME     $row->PHONE\n");
    }
}
db2_close($conn);

?>

The above example will output:

The following example works with documents stored in 2 different XML columns in the SAMPLE database. It creates 2 temporary tables from the XML documents from 2 different columns and returns an SQL ResultSet with information regarding shipping status for the customer.

<?php

$conn = db2_connect("SAMPLE", "db2inst1", "ibmdb2");

$query = '
SELECT A.CID, A.NAME, A.PHONE, C.PONUM, C.STATUS
FROM
XMLTABLE(
XMLNAMESPACES (DEFAULT \'http://posample.org\'),
\'db2-fn:xmlcolumn("CUSTOMER.INFO")/customerinfo\'
COLUMNS
"CID" BIGINT PATH \'@Cid\',
"NAME" VARCHAR (50) PATH \'name\',
"PHONE" VARCHAR (50) PATH \'phone [ @type = "work"]\'
) as A,
PURCHASEORDER AS B,
XMLTABLE (
XMLNAMESPACES (DEFAULT \'http://posample.org\'),
\'db2-fn:xmlcolumn("PURCHASEORDER.PORDER")/PurchaseOrder\'
COLUMNS
"PONUM"  BIGINT PATH \'@PoNum\',
"STATUS" VARCHAR (50) PATH \'@Status\'
) as C
WHERE A.CID = B.CUSTID AND
    B.POID = C.PONUM AND
    A.NAME = ?
';

$stmt = db2_prepare($conn, $query);

$name = 'Kathy Smith';

if ($stmt) {
    db2_bind_param($stmt, 1, "name", DB2_PARAM_IN);
    db2_execute($stmt);

    while($row = db2_fetch_object($stmt)){
    printf("$row->CID     $row->NAME     $row->PHONE     $row->PONUM     $row->STATUS\n");
    }
}

db2_close($conn);

?>

The following example works with a portion of the PRODUCT.DESCRIPTION documents in the SAMPLE database. It creates a XML document containing product description (XML data) and pricing info (SQL data).

<?php

$conn = db2_connect("SAMPLE", "db2inst1", "ibmdb2");

$query = '
SELECT
XMLSERIALIZE(
XMLQUERY(\'
    declare boundary-space strip;
    declare default element namespace "http://posample.org";
    <promoList> {
    for $prod in $doc/product
    where $prod/description/price < 10.00
    order by $prod/description/price ascending
    return(
        <promoitem> {
        $prod,
        <startdate> {$start} </startdate>,
        <enddate> {$end} </enddate>,
        <promoprice> {$promo} </promoprice>
            } </promoitem>
    )
    } </promoList>
\' passing by ref DESCRIPTION AS "doc",
PROMOSTART as "start",
PROMOEND as "end",
PROMOPRICE as "promo"
RETURNING SEQUENCE)
AS CLOB (32000))
AS NEW_PRODUCT_INFO
FROM PRODUCT
WHERE PID = ?
';

$stmt = db2_prepare($conn, $query);

$pid = "100-100-01";

if ($stmt) {
    db2_bind_param($stmt, 1, "pid", DB2_PARAM_IN);
    db2_execute($stmt);

    while($row = db2_fetch_array($stmt)){
    printf("$row[0]\n");
    }
}

db2_close($conn);

?>

The above example will output:
