db2_execute

Executes a prepared SQL statement

bool **db2_execute** resource $stmt array $parameters
executes an SQL statement that was

prepared by . db2_execute``db2_prepare

If the SQL statement returns a result set, for example, a SELECT statement or a CALL to a stored procedure that returns one or more result sets, you can retrieve a row as an array from the resource using , , or . Alternatively, you can use to move the result set pointer to the next row and fetch a column at a time from that row with . stmt``db2_fetch_assoc``db2_fetch_both``db2_fetch_array``db2_fetch_row``db2_result

Refer to for a brief discussion of the advantages of using and rather than . db2_prepare``db2_prepare``db2_execute``db2_exec

stmt A prepared statement returned from . db2_prepare

parametersAn array of input parameters matching any parameter markers contained in the prepared statement.

return.success

Voorbeeld: Preparing and executing an SQL statement with parameter markers

 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.";
    }
}
?>
Successfully added new pet.

Voorbeeld: Calling a stored procedure with an OUT parameter

 The following example prepares a CALL statement that accepts one
 parameter marker representing an OUT parameter, binds the PHP variable
  to the parameter using
 , then issues
  to execute the CALL statement. After the
 CALL to the stored procedure has been made, the value of
  changes to reflect the value returned by the
 stored procedure for that OUT parameter.
`$my_pets``db2_bind_param``db2_execute``$num_pets`
<?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!";
?>
I have 7 pets!

Voorbeeld: Returning XML data as an SQL ResultSet

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);

?>
1000     Kathy Smith     416-555-1358
1001     Kathy Smith     905-555-7258

Voorbeeld: Performing a "JOIN" with XML data

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);

?>
1001     Kathy Smith     905-555-7258     5002     Shipped

Voorbeeld: Returning SQL data as part of a larger XML document

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);

?>
