HOME > PHP Manual > db2_exec - Executes an SQL statement directly




(PECL ibm_db2:1.0-1.6.2)

db2_exec Executes an SQL statement directly


resource db2_exec ( resource $connection , string $statement [, array $options ] )

Executes an SQL statement directly.

If you plan to interpolate PHP variables into the SQL statement, understand that this is one of the more common security exposures. Consider calling db2_prepare() to prepare an SQL statement with parameter markers for input values. Then you can call db2_execute() to pass in the input values and avoid SQL injection attacks.

If you plan to repeatedly issue the same SQL statement with different parameters, consider calling db2_prepare() and db2_execute() to enable the database server to reuse its access plan and increase the efficiency of your database access.



A valid database connection resource variable as returned from db2_connect() or db2_pconnect().


An SQL statement. The statement cannot contain any parameter markers.


An associative array containing statement options. You can use this parameter to request a scrollable cursor on database servers that support this functionality.


Passing the DB2_FORWARD_ONLY value requests a forward-only cursor for this SQL statement. This is the default type of cursor, and it is supported by all database servers. It is also much faster than a scrollable cursor.

Passing the DB2_SCROLLABLE value requests a scrollable cursor for this SQL statement. This type of cursor enables you to fetch rows non-sequentially from the database server. However, it is only supported by DB2 servers, and is much slower than forward-only cursors.

Return Values

Returns a statement resource if the SQL statement was issued successfully, or FALSE if the database failed to execute the SQL statement.


Example #1 Creating a table with db2_exec()

The following example uses db2_exec() to issue a set of DDL statements in the process of creating a table.


// Create the test table
$create 'CREATE TABLE animals (id INTEGER, breed VARCHAR(32),
    name CHAR(16), weight DECIMAL(7,2))'
$result db2_exec($conn$create);
if (
$result) {
"Successfully created the table.\n";

// Populate the test table
$animals = array(
3'gold fish''Bubbles'0.1),
5'goat''Rickety Ride'9.7),

foreach (
$animals as $animal) {
$rc db2_exec($conn"INSERT INTO animals (id, breed, name, weight)
      VALUES ({$animal[0]}, '{$animal[1]}', '{$animal[2]}', {$animal[3]})"
    if (
$rc) {
"Insert... ";

The above example will output:

Successfully created the table.
Insert... Insert... Insert... Insert... Insert... Insert... Insert... 

Example #2 Executing a SELECT statement with a scrollable cursor

The following example demonstrates how to request a scrollable cursor for an SQL statement issued by db2_exec().

$sql "SELECT name FROM animals
    WHERE weight < 10.0
    ORDER BY name"
if (
$conn) {
$stmt db2_exec($conn$sql, array('cursor' => DB2_SCROLLABLE));
    while (
$row db2_fetch_array($stmt)) {


The above example will output:

Rickety Ride

Example #3 Returning XML data as a 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 a SQL ResultSet format that most users are familiar with.



    "CID" VARCHAR (50) PATH \'@Cid\',
    "NAME" VARCHAR (50) PATH \'name\',
    "PHONE" VARCHAR (50) PATH \'phone [ @type = "work"]\'
    ) AS T
    WHERE NAME = \'Kathy Smith\'
$stmt db2_exec($conn$query);

$row db2_fetch_object($stmt)){
printf("$row->CID     $row->NAME     $row->PHONE\n");


The above example will output:

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

Example #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 a SQL ResultSet with information regarding shipping status for the customer.



$query '
    "CID" BIGINT PATH \'@Cid\',
    "NAME" VARCHAR (50) PATH \'name\',
    "PHONE" VARCHAR (50) PATH \'phone [ @type = "work"]\'
    ) as A,
    "PONUM"  BIGINT PATH \'@PoNum\',
    "STATUS" VARCHAR (50) PATH \'@Status\'
    ) as C
    A.NAME = \'Kathy Smith\'

$stmt db2_exec($conn$query);

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



The above example will output:

1001     Kathy Smith     905-555-7258     5002     Shipped

Example #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).



$query '
    declare boundary-space strip;
    declare default element namespace "";
    <promoList> {
    for $prod in $doc/product
    where $prod/description/price < 10.00
    order by $prod/description/price ascending
        <promoitem> {
        <startdate> {$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"
AS CLOB (32000))
WHERE PID = \'100-100-01\'

$stmt db2_exec($conn$query);

$row db2_fetch_array($stmt)){


The above example will output:

<promoList xmlns="">
    <product pid="100-100-01">
            <name>Snow Shovel, Basic 22 inch</name>
            <details>Basic Snow Shovel, 22 inches wide, straight handle with D-Grip</details>
            <weight>1 kg</weight>
