$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.";
}
}
Результат выполнения данного примера:
Successfully added new pet.
Пример #2 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 $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.
$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!";
Результат выполнения данного примера:
I have 7 pets!
Пример #3 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.
$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);
Результат выполнения данного примера:
1000 Kathy Smith 416-555-1358
1001 Kathy Smith 905-555-7258
Пример #4 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.
$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);
Результат выполнения данного примера:
1001 Kathy Smith 905-555-7258 5002 Shipped
Пример #5 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).
$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);
Результат выполнения данного примера:
<promoList xmlns="http://posample.org">
<promoitem>
<product pid="100-100-01">
