INGRES_AUTOCOMMIT(3)							 1						      INGRES_AUTOCOMMIT(3)

ingres_autocommit - Switch autocommit on or off

SYNOPSIS

       bool ingres_autocommit (resource  $link)

DESCRIPTION

       ingres_autocommit(3)  is called before opening a transaction (before the first call to ingres_query(3) or just after a call to ingres_roll-
       back(3) or ingres_commit(3)) to switch the autocommit mode of the server on or off (when the script begins the autocommit mode is off).

	When autocommit mode is on, every query is automatically committed by the server, as if ingres_commit(3) was called after  every  call	to
       ingres_query(3). To see if autocommit is enabled use, ingres_autocommit_state(3).

	By default Ingres will rollback any uncommitted transactions at the end of a request. Use this function or ingres_commit(3) to ensure your
       data is committed to the database.

PARAMETERS

	      o $link
		- The connection link identifier

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

ingres_unbuffered_query - Send an unbuffered SQL query to Ingres

SYNOPSIS

       mixed ingres_unbuffered_query (resource	$link, string  $query, [array  $params], [string  $types])

DESCRIPTION

       ingres_unbuffered_query(3) sends the given $query to the Ingres server.

	The query becomes part of the currently open transaction. If there is no open transaction, ingres_unbuffered_query(3) opens a new transac-
       tion. To close the transaction, you can call either ingres_commit(3) to commit the changes made to the database	or  ingres_rollback(3)	to
       cancel  these  changes.	When  the  script  ends,  any  open  transaction  is rolled back (by calling ingres_rollback(3)). You can also use
       ingres_autocommit(3) before opening a new transaction to have every SQL query immediately committed. Ingres allows only a single unbuffered
       statement to be active at any one time. The extension will close any active unbuffered statements before executing any SQL. In addition you
       cannot use ingres_result_seek(3) to position the row before fetching.

       Note

	       See also the ingres.describe and ingres.utf8 directives in Runtime Configuration.

PARAMETERS

	      o $link
		- The connection link identifier

	      o $query
		- A valid SQL query (see the Ingres SQL reference guide) in the Ingres documentation. See the query parameter  in  ingres_query(3)
		for  a	list  of  SQL statements that cannot be executed via ingres_unbuffered_query(3).  Data inside the query should be properly
		escaped.

	      o $params
		- An array of parameter values to be used with the query

	      o $types
		- A string containing a sequence of types for the parameter values passed. See the types parameter in ingres_query(3) for the list
		of type codes.

RETURN VALUES

       ingres_unbuffered_query(3) returns a query result identifier when there are rows to fetch; else it returns FALSE when there are no rows, as
       is the case of an INSERT, UPDATE, or DELETE statement. To see if an error occurred, use ingres_errno(3), ingres_error(3), or ingres_errsql-
       state(3).

EXAMPLES

       Example #1

	      Issue a simple un-buffered select

	      <?php
	      $link = ingres_connect("demodb");

	      $result = ingres_unbuffered_query($link, "select * from user_profile");
	      while ($row = ingres_fetch_row($result)) {
		  echo $row[1];
		  echo $row[2];
	      }
	      ?>

       Example #2

	      Passing query parameters to ingres_unbuffered_query(3)

	      <?php
	      $link = ingres_connect("demodb");

	      $params[] = "Emma";
	      $query = "select * from user_profile where up_first = ?";
	      $result = ingres_unbuffered_query($link, $query, $params);
	      while ($row = ingres_fetch_row($result)) {
		  echo $row[1];
		  echo $row[2];
	      }
	      ?>

       Example #3

	      Inserting a BLOB with parameter types

	      <?php
	      $link = ingres_connect("demodb");

	      //Open a photo
	      $fh = fopen("photo.jpg","r");
	      $blob_data = stream_get_contents($fh);
	      fclose($fh);

	      //Prepare parameters
	      $params[] = $blob_data;
	      $params[] = 1201;

	      //Define parameter types
	      $param_types = "Bi";

	      $query = "update user_profile set up_image = ? where up_id = ?";
	      $result = ingres_unbuffered_query($link, $query , $params, $param_types);

	      if (ingres_errno())
	      {
		  echo ingres_errno() . "-" . ingres_error() . "
";
	      }
	      ?>
