SQLSRV_NUM_ROWS(3)														SQLSRV_NUM_ROWS(3)

sqlsrv_num_rows - Retrieves the number of rows in a result set

SYNOPSIS

       mixed sqlsrv_num_rows (resource	$stmt)

DESCRIPTION

	Retrieves the number of rows in a result set. This function requires that the statment resource be created with a static or keyset cursor.
       For more information, see sqlsrv_query(3), sqlsrv_prepare(3), or Specifying a Cursor Type and Selecting Rows in the Microsoft SQLSRV  docu-
       mentation.

PARAMETERS

	      o $stmt
		-  The	statement  for	which the row count is returned. The statment resource must be created with a static or keyset cursor. For
		more information, see sqlsrv_query(3), sqlsrv_prepare(3), or Specifying a Cursor Type and Selecting Rows in the  Microsoft  SQLSRV
		documentation.

RETURN VALUES

	Returns  the  number  of  rows retrieved on success and FALSE if an error occurred. If a forward cursor (the default) or dynamic cursor is
       used, FALSE is returned.

EXAMPLES

       Example #1

	      sqlsrv_num_rows(3) example

	      <?php
	      $server = "serverNamesqlexpress";
	      $connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password" );
	      $conn = sqlsrv_connect( $server, $connectionInfo );

	      $sql = "SELECT * FROM Table_1";
	      $params = array();
	      $options =  array( "Scrollable" => SQLSRV_CURSOR_KEYSET );
	      $stmt = sqlsrv_query( $conn, $sql , $params, $options );

	      $row_count = sqlsrv_num_rows( $stmt );

	      if ($row_count === false)
		 echo "Error in retrieveing row count.";
	      else
		 echo $row_count;
	      ?>

sqlsrv_fetch_array - Returns a row as an array

SYNOPSIS

       array sqlsrv_fetch_array (resource  $stmt, [int	$fetchType], [int  $row], [int	$offset])

DESCRIPTION

	Returns the next available row of data as an associative array, a numeric array, or both (the default).

PARAMETERS

	      o $stmt
		- A statement resource returned by sqlsrv_query or sqlsrv_prepare.

	      o $fetchType
		-  A predefined constant specifying the type of array to return. Possible values are SQLSRV_FETCH_ASSOC, SQLSRV_FETCH_NUMERIC, and
		SQLSRV_FETCH_BOTH (the default).  A fetch type of SQLSRV_FETCH_ASSOC should not be used when consuming a result set with  multiple
		columns of the same name.

	      o $row
		-  Specifies  the  row	to  access  in	a  result  set that uses a scrollable cursor. Possible values are SQLSRV_SCROLL_NEXT, SQL-
		SRV_SCROLL_PRIOR, SQLSRV_SCROLL_FIRST, SQLSRV_SCROLL_LAST, SQLSRV_SCROLL_ABSOLUTE and, SQLSRV_SCROLL_RELATIVE (the default).  When
		this parameter is specified, the $fetchType must be explicitly defined.

	      o $offset
		-  Specifies the row to be accessed if the row parameter is set to SQLSRV_SCROLL_ABSOLUTE or SQLSRV_SCROLL_RELATIVE. Note that the
		first row in a result set has index 0.

RETURN VALUES

	Returns an array on success, NULL if there are no more rows to return, and FALSE if an error occurs.

EXAMPLES

       Example #1

	      Retrieving an associative array.

	      <?php
	      $serverName = "serverNameinstanceName";
	      $connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password");
	      $conn = sqlsrv_connect( $serverName, $connectionInfo );
	      if( $conn === false ) {
		  die( print_r( sqlsrv_errors(), true));
	      }

	      $sql = "SELECT FirstName, LastName FROM SomeTable";
	      $stmt = sqlsrv_query( $conn, $sql );
	      if( $stmt === false) {
		  die( print_r( sqlsrv_errors(), true) );
	      }

	      while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_ASSOC) ) {
		    echo $row['LastName'].", ".$row['FirstName']."<br />";
	      }

	      sqlsrv_free_stmt( $stmt);
	      ?>

       Example #2

	      Retrieving a numeric array.

	      <?php
	      $serverName = "serverNameinstanceName";
	      $connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password");
	      $conn = sqlsrv_connect( $serverName, $connectionInfo );
	      if( $conn === false ) {
		  die( print_r( sqlsrv_errors(), true));
	      }

	      $sql = "SELECT FirstName, LastName FROM SomeTable";
	      $stmt = sqlsrv_query( $conn, $sql );
	      if( $stmt === false) {
		  die( print_r( sqlsrv_errors(), true) );
	      }

	      while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_NUMERIC) ) {
		    echo $row[0].", ".$row[1]."<br />";
	      }

	      sqlsrv_free_stmt( $stmt);
	      ?>

NOTES

	Not specifying the $fetchType or explicity using the SQLSRV_FETCH_TYPE constant in the examples above will return an array that  has  both
       associative and numeric keys.

	If more than one column is returned with the same name, the last column will take precedence. To avoid field name collisions, use aliases.

	If a column with no name is returned, the associative key for the array element will be an empty string ("").
