db2_execute - Executes a prepared SQL statement

SYNOPSIS

       bool db2_execute (resource  $stmt, [array  $parameters])

DESCRIPTION

       db2_execute(3) executes an SQL statement that was prepared by db2_prepare(3).

	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 stmt resource using db2_fetch_assoc(3), db2_fetch_both(3), or db2_fetch_array(3).  Alter-
       natively,  you  can  use  db2_fetch_row(3)  to  move the result set pointer to the next row and fetch a column at a time from that row with
       db2_result(3).

	Refer to db2_prepare(3) for a brief discussion of the advantages of using db2_prepare(3) and db2_execute(3) rather than db2_exec(3).

PARAMETERS

	      o $stmt
		- A prepared statement returned from db2_prepare(3).

	      o $parameters
		- An array of input parameters matching any parameter markers contained in the prepared statement.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      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  con-
	      taining the input values to be passed to db2_execute(3).

	      <?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:

	      Successfully added new pet.

       Example #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(3), then issues db2_execute(3) 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 above example will output:

	      I have 7 pets!

       Example #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.

	      <?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     $row->PHONE
");
		  }
	      }
	      db2_close($conn);

	      ?>

	      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 an SQL ResultSet with information regarding shipping status for the cus-
	      tomer.

	      <?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
");
		  }
	      }

	      db2_close($conn);

	      ?>

	      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).

	      <?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]
");
		  }
	      }

	      db2_close($conn);

	      ?>

	      The above example will output:

	      <promoList xmlns="http://posample.org">
		  <promoitem>
		  <product pid="100-100-01">
		      <description>
			  <name>Snow Shovel, Basic 22 inch</name>
			  <details>Basic Snow Shovel, 22 inches wide, straight handle with D-Grip</details>

		      </description>
		  </product>
		  <startdate>2004-11-19</startdate>
		  <enddate>2004-12-19</enddate>
		  <promoprice>7.25</promoprice>
		  </promoitem>
	      </promoList>
