fbsql_errno - Returns the error number from previous operation

SYNOPSIS

       int fbsql_errno ([resource  $link_identifier])

DESCRIPTION

	Returns the numerical value of the error message from previous FrontBase operation.

	Errors coming back from the fbsql database backend don't issue warnings. Instead, use fbsql_errno(3) to retrieve the error code. Note that
       this function only returns the error code from the most recently executed fbsql function (not including fbsql_error(3) and fbsql_errno(3)),
       so if you want to use it, make sure you check the value before calling another fbsql function.

PARAMETERS

	      o $
		link_identifier  -A FrontBase link identifier returned by fbsql_connect(3) or fbsql_pconnect(3).If optional and not specified, the
		function will try to find an open link to the FrontBase server and if no such link is found it	will  try  to  create  one  as	if
		fbsql_connect(3) was called with no arguments.

RETURN VALUES

	Returns the error number from the last fbsql function, or 0 (zero) if no error occurred.

EXAMPLES

       Example #1

	      fbsql_errno(3) Example

	      <?php
	      fbsql_connect("marliesle");
	      echo fbsql_errno() . ": " . fbsql_error() . "<br />";
	      fbsql_select_db("nonexistentdb");
	      echo fbsql_errno() . ": " . fbsql_error() . "<br />";
	      $conn = fbsql_query("SELECT * FROM nonexistenttable;");
	      echo fbsql_errno() . ": " . fbsql_error() . "<br />";
	      ?>

fbsql_read_blob - Read a BLOB from the database

SYNOPSIS

       string fbsql_read_blob (string  $blob_handle, [resource	$link_identifier])

DESCRIPTION

	Reads BLOB data from the database.

	If  a select statement contains BLOB and/or CLOB columns FrontBase will return the data directly when data is fetched. This default behav-
       ior can be changed with fbsql_set_lob_mode(3) so the fetch functions will return handles to BLOB and CLOB data. If a handle  is	fetched  a
       user must call fbsql_read_blob(3) to get the actual BLOB data from the database.

PARAMETERS

	      o $blob_handle
		- A BLOB handle, returned by fbsql_create_blob(3).

	      o $
		link_identifier  -A FrontBase link identifier returned by fbsql_connect(3) or fbsql_pconnect(3).If optional and not specified, the
		function will try to find an open link to the FrontBase server and if no such link is found it	will  try  to  create  one  as	if
		fbsql_connect(3) was called with no arguments.

RETURN VALUES

	Returns a string containing the specified BLOB data.

EXAMPLES

       Example #1

	      fbsql_read_blob(3) example

	      <?php
	      $link = fbsql_pconnect("localhost", "_SYSTEM", "secret")
		  or die("Could not connect");
	      $sql = "SELECT BLOB_COLUMN FROM BLOB_TABLE;";
	      $rs = fbsql_query($sql, $link);
	      $row_data = fbsql_fetch_row($rs);
	      // $row_data[0] will now contain the blob data for the first row
	      fbsql_free_result($rs);

	      $rs = fbsql_query($sql, $link);
	      fbsql_set_lob_mode($rs, FBSQL_LOB_HANDLE);
	      $row_data = fbsql_fetch_row($rs);
	      // $row_data[0] will now contain a handle to the BLOB data in the first row
	      $blob_data = fbsql_read_blob($row_data[0]);
	      fbsql_free_result($rs);

	      ?>
